The T24 Career Circular Trap

At some point, every T24 professional has tried to help someone break into the field and discovered that the advice sounds like a riddle. “You need T24 experience.” “How do I get T24 experience?” “By working on T24.” “But to work on T24 I need T24 experience.” “Yes.”

This is the circular trap, and it is not unique to T24. Every enterprise technology with a small professional community has it — SAP, Temenos, FIS, Finastra. The difference with T24 is that the community is smaller than most and the knowledge is more concentrated. There are maybe ten thousand people worldwide who could credibly describe themselves as experienced T24 professionals. That is a village. Villages have specific entry protocols, and the official routes do not always work the way you would expect.

This article covers how the circular trap actually operates, the paths people have used to get through it, and the career dynamics of a technology where your reputation is a currency and some of the most valuable knowledge never appears in documentation.

Why the trap exists

The circular trap exists for three reasons, and understanding them is the first step to navigating around them rather than through them.

The technology is not publicly available. You cannot download T24, install it on a laptop, and start learning. There is no community edition. There is no free tier. There is no cloud sandbox you can spin up with a credit card. The software runs inside banks and at Temenos-hosted environments. Access requires either working at a bank that runs T24, working for a consultancy with a client that runs T24, or working for Temenos itself. This is the hard gate, and it is the reason the usual advice — “build something, put it on GitHub, demonstrate your skills” — does not apply here. You cannot build something.

The hiring risk is asymmetric. A T24 project is expensive. A failed go-live can cost a bank millions and end careers. When a hiring manager looks at a CV, they are not asking “can this person learn T24?” They are asking “can this person be trusted on a production system where a mistake affects real money?” The difference between those two questions is the difference between hiring someone with no T24 experience and hiring someone who has already made their expensive mistakes somewhere else. The hiring manager picks the second person every time, because the cost of being wrong about the first person is not measured in recruitment fees. It is measured in COB failures and incident calls.

The knowledge is tribal. The official Temenos documentation is comprehensive in the way a reference manual is comprehensive — it tells you what each parameter does, not how to run a COB recovery at 2am without making the situation worse. The knowledge that makes you effective in T24 is held by the people who have been doing it for years, passed through teams and projects, and only partially written down. Access to this knowledge requires access to these people, which requires being inside the community, which requires having a job that gives you that access. Circular.

The paths that actually work

Everyone who is now experienced in T24 was once not experienced in T24. The paths into the field exist. They are just not evenly distributed or equally visible. Here are the ones that work, presented honestly, with the trade-offs.

The bank back door

This is the most common path for people already working in banking IT. You are in a bank that runs T24. You are not on the T24 team — you are on the integration team, or the reporting team, or the middleware team, or the testing team. You work adjacent to T24. You see the interfaces. You understand what T24 does, at least from the outside. You express interest. You volunteer for the testing phase of the next release. You become the person on your team who knows how to talk to the T24 team.

After a year of this, you apply for an internal transfer to the T24 team. Internally, the hiring bar is lower. The bank already knows you. They know you are not going to cause a production incident through recklessness. They know you understand the bank's specific T24 setup because you have been watching it from the adjacent building for twelve months. You get the transfer. You spend the first six months feeling completely lost, which is normal. After two years, you are experienced. You now have the thing every job posting asks for.

This path is not fast. It requires already being inside a bank that runs T24, which is a significant prerequisite that the path description does not help with if you are not. But for people in that position, it is the most reliable route. The key insight: do not apply for the T24 role from outside. Get inside the bank first, in any IT role that touches T24 even tangentially, and move sideways.

The consultancy entry

T24 consultancies — the large ones, the specialist ones, the ones that provide managed services — hire people with adjacent skills and train them. They have to. The T24 talent pool is too small to hire only experienced people, and the consultancies that tried that approach eventually ran out of people to hire and started losing contracts to the ones that built their own talent.

The entry points: strong core banking knowledge from another system (FIS, Finastra, Oracle FLEXCUBE), strong Java development skills, strong testing and QA skills in a banking context, strong business analysis skills with payments or lending domain knowledge. Notice the pattern: none of these say T24 experience. They say adjacent experience that a consultancy can convert into T24 capability over six to twelve months of project work under supervision.

The trade-off: consultancy entry roles typically pay less than experienced contractor rates, sometimes significantly less. The consultancy is investing in you, and the return on that investment is the difference between what they bill the client for you and what they pay you. You accept this because at the end of eighteen months you have T24 experience on your CV and you are no longer subject to the circular trap. The person who took this deal three years ago is now on a contractor rate and the eighteen-month discount feels like a reasonable price for the career it bought.

The Temenos route

Temenos hires graduates, trains them on the product, and deploys them on client projects. This is the most direct path to T24 expertise — you learn from the people who built it, you see multiple implementations, and you build a network that follows you for the rest of your career. The trade-offs: travel, sometimes extensive; the pace of consulting work, which is not for everyone; and the reality that you are learning a proprietary technology that does not transfer directly to any other platform.

Temenos alumni are disproportionately represented in senior T24 roles across the industry. This is not a coincidence. The Temenos training programme, combined with exposure to multiple banks and multiple implementations, produces people who have seen more variety in three years than someone at a single bank sees in ten. When those people leave Temenos, they become the experienced hires that banks and consultancies compete for.

For someone at the start of their career who is willing to commit to the T24 ecosystem, this is the highest-return path. For someone mid-career who cannot accept a graduate-entry salary, it is a harder sell.

The operational entry

Every T24 implementation has an operations team that monitors COB, handles incident first response, and manages the batch schedule. These roles do not require deep T24 configuration knowledge. They require the ability to follow a runbook, recognise when something looks wrong, and call the right person.

Operations roles are the most common entry point for people who do not have T24 experience but do have IT operations experience — monitoring, batch scheduling, incident management. After six months of watching COB run every night, you know what healthy looks like. After a year, you know what the common failure patterns look like. After two years, you can diagnose incidents faster than some of the development team, because you have seen the system under pressure more often than they have.

From operations, the move into a more technical T24 role is a conversation with the T24 team lead, not a cold application. You have been keeping their system alive at 2am for two years. They know you. They trust you. The transition from operations to development or support is common enough that it has its own informal pipeline in several large banks. Nobody talks about it because the people who took this path are now in senior roles and have politely forgotten that they started by reading COB logs at 3am while hoping nothing broke.

Switching modules mid-career

A slightly different version of the circular trap affects people who are already in T24 but want to move from one module to another. You have five years of COB and operations experience. You want to move into TPH. Every TPH role requires TPH experience. Your five years of COB experience is clearly valuable — you understand the batch cycle, you understand how TPH interacts with COB, you understand the production support patterns — but recruiters are searching for the word “TPH” on your CV and not finding it, so your application does not reach the hiring manager.

The module-switching trap is less severe than the entry trap because you have a significant advantage: you already understand how T24 works as a system. You know what COB does. You know how services start and stop. You know where the logs live. You know the difference between a stuck record lock and a configuration problem. None of this is module-specific, and all of it transfers to any module you move into.

The practical path for switching modules:

• Pick the module you want to move into and learn its fundamentals before you apply for the role. Read the documentation. Understand the terminology. If possible, get access to a non-production environment and explore. When you interview, you need to demonstrate that you have already invested the effort, not that you are expecting the new role to teach you from scratch.
• Frame your existing experience in terms of the target module. “Five years of COB support, including managing TPH-related batch failures” is a sentence that contains the word TPH. It is also true. Most T24 professionals have touched more modules than they list on their CV because they do not think of cross-module exposure as module experience. It counts.
• Target roles where your existing module knowledge is a complement, not a replacement. A TPH support role in a bank that is also strengthening its COB monitoring is a better fit than a pure TPH development role where nobody cares about COB. Your five years of COB experience is a differentiator in the first scenario and irrelevant in the second. Apply for the roles where it is a differentiator.
• Talk to the TPH people at your current bank. Ask what they do day to day. Ask what they wish they had known when they started. Ask if you can shadow them during the next TPH release. The internal path between modules is almost always easier than the external one, and the person you shadow today might be the person who recommends you for the role in six months.

The recruiter problem

A significant part of the circular trap is not the banks. It is the recruiters. Most T24 recruitment goes through agencies who are searching CVs for keywords. If your CV does not say TPH, you will not be put forward for a TPH role regardless of whether your actual experience is relevant. The recruiter does not know what COB means. They know the client asked for TPH experience and your CV does not mention TPH. Next.

This is frustrating but it is not personal. The recruiter is processing fifty CVs for five roles and their screening tool is keyword matching. You cannot change the recruitment industry. You can change your CV.

The fix: your CV should list every module you have genuinely encountered in a production context, even if your exposure was partial. Not “experienced in T24.” “Experienced in T24 COB, including TPH batch interaction and AA arrangement processing during end-of-day.” The first version does not pass the keyword filter for any specific T24 role. The second version passes the filter for COB roles, TPH roles, and AA roles. You are not misrepresenting your experience. You are describing it at a level of specificity that the keyword filter can actually process.

The other recruiter-related problem is the job description that asks for ten years of experience in a module that has existed for seven. This happens. The job description was written by someone who does not know the technology and was not given enough information to write a meaningful specification. Apply anyway. The hiring manager knows the module has only existed for seven years. They also know the job description is aspirational. If you have five years of relevant experience and can articulate it well, you are in the conversation.

The real career dynamics of T24

The T24 professional community is small enough that reputation matters more than CV length. After a few years, you stop applying for roles through agencies and start getting calls from people you worked with on a project three years ago who are now leading a different project and need someone they trust. This shift usually happens around the five-year mark. Before that, you are building the reputation. After that, the reputation is doing some of the work for you.

This has implications for how you behave in every role, especially the early ones. The person you help at 2am during a COB incident is a future hiring manager. The team lead who watches you handle a difficult escalation calmly and competently is the person who will recommend you for a role at their next bank. The consultant you work alongside for six months is the person who will call you when their client asks if they know anyone good. These are not hypothetical scenarios. In a community this small, they are the primary career mechanism.

The practical implication: do good work, be helpful under pressure, and do not burn bridges. The T24 community is too small for bridge-burning to be a viable career strategy. Someone you clash with today will be on the interview panel for a role you want in three years. This is not a moral argument. It is a practical observation from a village where everyone eventually works with everyone.

What to actually do now

If you are currently outside T24 and trying to get in:

1. If you work at a bank that runs T24, the internal transfer path is your best option. Get into any IT role that touches T24. Move sideways. This works.
2. If you do not work at a bank that runs T24, the consultancy entry is your most realistic path. Target the consultancies that actively recruit people with adjacent banking IT skills. Accept the initial rate discount as an investment in the career it buys.
3. If you are at the start of your career, the Temenos graduate programme is the highest-return path and the one that produces the most senior people in the industry over a ten-year horizon.
4. If you have IT operations experience, the operational entry through a T24 operations role is a viable and under-discussed route. Operations teams hire for IT operations skills, not T24 configuration knowledge. Once inside, the path to a more technical role is open.

If you are already in T24 and trying to switch modules:

1. Learn the target module's fundamentals before applying. Read the documentation. Shadow someone. Get hands-on if you can.
2. Frame your existing experience in terms of the target module. Your COB knowledge is relevant to TPH. Your integration knowledge is relevant to AA. Say so on your CV.
3. Target roles where your existing module knowledge is a strength, not just background. Apply for TPH support roles that value COB experience, not TPH development roles that require deep TPH configuration knowledge on day one.
4. Talk to the people already doing the role you want. Internal moves between modules are significantly easier than external ones, and the conversation starts with the person at the next desk, not with a recruiter.

The thing nobody tells you

The honest truth about the T24 career circular trap is that it is real but it is surmountable. Everyone who is currently inside T24 was once outside T24, looking at the same job postings, reading the same experience requirements, and trying to figure out how the system was supposed to work when the entry criteria appeared to exclude anyone not already inside.

The paths exist. They are not advertised. They are not in the job descriptions. They are in the operational teams that hire for IT operations skills, the consultancies that build their own talent because the market cannot supply enough experienced people, the banks that transfer people internally because they already know and trust them, and the Temenos graduate programme that produces a disproportionate number of the senior people in the field.

The trap looks impenetrable from the outside. From the inside, it looks like a series of side doors that people used because the front door was locked and they found another way in. Find your side door. It is there. It is probably not the one you have been looking at.
