Job description

engine room: pre-trade risk checks, margin logic, position lifecycle, liquidation paths, and guardrails/kill-switch controls.Partner across teams to define clean boundaries, failure modes, and rollout strategy as the platform evolves.Build foundations properly: HA, horizontal scaling, zero-downtime upgrades, safe rollouts, incident playbooks and post-mortems that lead to measurable improvements.Put observability everywhere: tracing/metrics/logging, SLOs, alerting, capacity signals and performance regression detection.Create simulation and replay harnesses to validate changes before production (load, failover, extreme market conditions).Be the Rust thought leader internally: set standards, coach engineers, and raise the quality bar across the platform.What we're looking for3+ years minimum Rust in production, building performance-critical systems.7+ years backend engineering experience overall.Ultra-low latency mindset: hot-path profiling, lock-free/low-lock concurrency, cache/memory layout, backpressure, and reducing jitter.Exchange experience across 70%+ of the core components, for example: matching/order book, execution/order routing, risk, margin, positions, market data/streaming, internal APIs and monitoring.Comfort owning the full loop: requirements * architecture * implementation * measurement * rollout * on-call/incident response.Able to explain what you changed, how you measured it, and the impact (latency, throughput, stability, trading outcomes).Nice to haveDerivatives experience (traditional or crypto), and familiarity with funding, liquidation flows, and margining models.Event-driven architectures (Kafka-style), Redis, distributed systems patterns, high-throughput data pipelines.Protocols/feeds: FIX, binary feeds, ITCH/OUCH, SBE/Aeron-style IPC, shared memory patterns.Systems optimisation: CPU pinning/affinity, NUMA, cache locality, IRQ/interrupt tuning, NIC tuning, kernel bypass/DPDK.Open-source contributions in Rust or trading infrastructure.Why this roleTrue exchange rebuild with a 2+ year runway and strong backingTop-of-market comp with real ownership via equityHigh-trust environment reporting into the CTO + CRO, with scope to set backend direction and build a teamIdeal for HFT engineers who want to keep the performance edge without trading seat restrictionsIf you're a senior Rust engineer/architect who's built most of an exchange (order book to risk) and you want to lead a serious rebuild, apply here or message me and I'll share details.
