Java Developer – 12-Month FTC | Greenfield Build | London
We’re partnering with a leading systematic hedge fund on an exciting opportunity for a Senior Java Developer to join their Middle Office Engineering team. The team is embarking on a greenfield digital transformation programme, rebuilding key trading and operational systems from the ground up.
Location: Central London (4 days per week in office – non-negotiable)
Engagement : 12-month Fixed-Term Contract, rolling based on start date
Salary: £130k base + potential completion bonus
Start date: ASAP – 1 month notice acceptable
The Role
You’ll work as a hands-on contributor in a team of high-performing engineers, taking full ownership of technical delivery. The current focus is an internal project, a large-scale initiative replacing legacy internal platforms with a more modern, performant, and scalable system.
Expect to build across trading support systems, infrastructure, and execution tools, with strong autonomy and end-to-end ownership.
What They’re Looking For
Key Skills:
Strong Java experience (Java 17 )
Kafka – Power User level only (critical requirement)
Microservices experience is a nice-to-have
Background & Experience:
Deep, production-grade Kafka experience is non-negotiable
6–8+ years of commercial Java development
Financial services experience is a plus (swaps, pricing, middle/back office etc.) but not essential
Important Notes
This is an on-site role (4 days/week) – no remote/hybrid flex beyond the agreed schedule
Please only apply if you're 100% comfortable with that
The team is looking for engineers, not managers – strong individual contributors only
Interview Process
30–45 min technical screen with engineering leads
On-site technical deep dive (~2–2.5 hours) with the wider team
Feedback and offer turnaround expected within days
If you’re a seasoned Java developer with serious Kafka experience and want to work on a genuinely interesting greenfield project at a high-performance trading firm, this is well worth a conversation.
