Systems that cannot be down at the open.
Most software can be retried. This cannot. If you find that constraint interesting rather than stressful, we should talk.
- What it is
- Engineering, product, operations and support roles building and running the Raptor ecosystem.
- Who it is for
- People who like correctness, latency, and systems where the failure mode has a cost attached.
- Why it matters
- Financial infrastructure rewards care. It is one of the few places where being pedantic is a professional virtue.
- How it connects
- Small teams own whole surfaces end to end, including the operational consequences.
- What happens next
- Send a message describing what you have built and what you want to work on.
6 open roles
What we are hiring for.
Small teams owning whole surfaces, including the operational consequences. No role here is a ticket queue.
Senior Frontend Engineer
Ruislip, UK · or remote
The trading surface. Real-time data, dense interfaces, and the requirement that none of it stutters while a market is moving.
Apply for this role- Build and own parts of the terminal: charting workspaces, order tickets, position and risk panels.
- Keep interfaces responsive under a live tick stream — worker offloading, render budgets, measuring rather than guessing.
- Work in TypeScript strict with a design-token system, in both light and dark, at every breakpoint.
- Care about the details traders notice: tabular numerals that do not jitter, refusals that explain themselves.
- Strong React and TypeScript, and opinions about state management you can defend.
- Experience with real-time or data-dense interfaces — trading, monitoring, analytics, anything where the data does not sit still.
- Comfort with performance work as measurement rather than folklore.
- Financial markets experience is welcome but genuinely not required.
Execution & Risk Engineer
Ruislip, UK · or remote
The order path. Pre-trade validation, position keeping, and the limits that have to hold at the exact moment nobody has time to check them.
Apply for this role- Own order management and the risk engine that validates every order, human or automated.
- Implement exposure, concentration, drawdown and loss controls, and the audit trail behind them.
- Make refusals informative: which check, what value, which ceiling.
- Write the tests that matter when correctness is the requirement rather than a goal.
- Backend engineering where correctness has a cost attached — payments, exchanges, ledgers, clearing.
- Comfort reasoning about concurrency, idempotency and partial failure.
- Someone who finds "what happens if this fails halfway" the interesting part.
Market Connectivity Engineer
Ruislip, UK · or remote
Feed handlers and provider sessions — including everything that happens when they degrade rather than fail cleanly.
Apply for this role- Build and operate FIX and API sessions to liquidity providers and market data vendors.
- Handle the ugly cases: stale ticks, crossed books, session drops, silent degradation.
- Measure execution quality per provider, per instrument, per session — separately, not as one score.
- Define failover behaviour so a degraded session is contained rather than becoming an outage.
- FIX protocol experience, or strong network and protocol fundamentals plus willingness to learn it properly.
- Operational instinct — you have been on call for something that mattered.
- Scepticism about vendor claims, and a habit of verifying them.
Intelligence Engineer
Ruislip, UK · or remote
The intelligence layer: applied analysis with explicit boundaries and outputs a risk committee can read.
Apply for this role- Work on condition classification, input scoring and the re-ranking that keeps readings current.
- Make every output explainable — the reading, the inputs behind it, and the confidence in plain language.
- Keep the boundary between what the layer concludes and what it is permitted to do absolutely clean.
- Say clearly when a signal is weak. That is the job, not a failure of it.
- Applied statistics or ML in production, with a healthy suspicion of your own backtests.
- Willingness to describe rather than predict, and to publish the limitations.
- Interest in market structure — how liquidity, sessions and correlation actually behave.
Platform Operations Engineer
Ruislip, UK · hybrid
Running a platform through market hours. Most software can be retried; this cannot.
Apply for this role- Own monitoring, alerting and incident response across application, data and connectivity layers.
- Run deployments that avoid peak sessions, with rollback that has been rehearsed.
- Exercise the recovery plan rather than filing it.
- Write the post-incident reviews, honestly.
- Infrastructure-as-code, observability tooling, and container orchestration in production.
- Someone who has been woken up by a pager and improved the system afterwards.
- Calm under an incident, and precise in writing about it.
Client Solutions Engineer
Ruislip, UK · or remote
The technical face of the company. Configured demos, migrations, and the awkward integration questions.
Apply for this role- Configure demos against a prospect’s real instruments, sessions and risk policy.
- Lead technical evaluations and answer security due diligence accurately.
- Own migrations: clients, balances, history, and the parts nobody scoped.
- Feed what you hear back into the product rather than working around it.
- Enough engineering to be credible with engineers, enough clarity to be useful to a risk committee.
- Brokerage, trading platform or fintech integration experience.
- Willingness to say "that does not exist yet" to a prospect.
