The problem space

Markets move fast. Prices update in microseconds. Billions of events. Global users. No margin for latency spikes or silent failures.

We're a small, senior engineering team building the infrastructure that makes that work — event-driven, distributed, and genuinely performance-critical. Systems where correctness and latency are the product.

What you'll actually do

• Own hard problems end-to-end
• Write production code and set technical direction in the areas you lead
• Work directly with senior engineering leadership on critical architectural decisions
• Take deep technical ownership of complex, performance-critical systems
• You'll be the most senior technical IC in the company

The bar

• Strong production experience in Rust, Python, Go, or C++
• Experience building high-throughput, low-latency distributed systems at scale
• Kafka, Kubernetes, AWS - in production
• Comfortable reasoning about failure modes, tail latency, and system trade-offs
• Two or more years at Staff or Principal IC level

Why it's worth your time

• Full private health insurance
• Annual learning and development budget
• Flexibility to work from anywhere for up to one month a year
• A profitable, independently owned fintech operating at scale for over a decade - no VC pressure, no pivot risk

Compensation: £200k package (Base + Bonus) + equity, plus full benefits and hybrid flexibility.
