- Design storage and retrieval patterns for market data, trade history, positions and audit trails at high volume.
- Collaborate with the Product team and stakeholders to design technical solutions for new financial products.
- Participate in on-call rotations and respond to production incidents requiring deep technical troubleshooting.
- Set and uphold engineering standards across the platform, mentoring less senior engineers where appropriate.
What You'll Need:
- 8+ years of professional software engineering experience building high-performance, low-latency distributed systems.
- Expert-level Java proficiency including concurrency primitives, memory management, JVM internals and performance optimisation.
- Proven experience with Aeron, Hydra or comparable low-latency messaging frameworks.
- Track record of building systems handling 100,000+ messages/second, sub-millisecond p99 latency and 99.99%+ uptime.
- Experience with financial markets technology order books, matching algorithms and derivatives products.
- Degree in Computer Science, Software Engineering or a related discipline.
Desirable / Nice to Have:
- Direct experience with prediction markets, binary options or exchange-level clearing systems.
- Exposure to financial data architecture at scale -- trade history, positions, audit trails.
Why Apply?
- £100,000 - £135,000 salary with a highly attractive bonus and benefits package.
- Director-level technical leadership with genuine architectural influence not a management track.
- Work on exchange-grade infrastructure at institutional scale with microsecond precision.
