We're working with a proprietary trading firm, trading its own capital in the most competitive traditional markets for over a decade. Colocated infra with FPGAs handling market data decode and order entry.
The seat
You would join the team that covers everything behind the trade: the books and P&L, the risk numbers the desk trades against, position keeping, and daily reporting.
Half the role is hands-on Python - internal applications, ETL and data pipelines, deployment tooling and CI/CD, and reconciliation and data quality frameworks. This is genuine building, not scripting. The other half is running the estate: their own on-prem Linux, monitoring and alerting, and a pager rotation.
A trading background is preferred, but not required. Recent engineering hires came from outside the industry. Exchanges, clearing houses, banks and payments all count.
What you will want on your CV
- Python you have shipped into production
- Time spent running systems where downtime is expensive
- On-prem infrastructure rather than cloud consoles alone
- Containerised workloads, configuration management and infrastructure as code
- Mid or back office systems - P&L, positions, reconciliation - useful, not essential
Why them
Small firm and team. Sat close to the people who use what you build daily.
