Job summary

Keyrock is seeking a Senior Rust Engineer for its Capital Markets division. You will design, build, and run low-latency trading systems, owning components from architecture to production. You will collaborate with quants, traders, and engineers to deliver resilient, high‑performance solutions and drive improvements across the stack.

The role emphasizes AI‑driven workflows, automation, and a strong ownership mindset within a fully remote, global team expecting candidates in European time zones.

Qualifications

• Production‑grade Rust experience building high‑performance, concurrent systems; proficiency with Tokio is a strong advantage.
• Hands‑on experience in a systematic trading environment (HFT, Market Making, Quantitative Trading, or similar) with solid understanding of execution, market data, and operational risk.
• Strong AWS and Linux expertise, including cloud infrastructure trade‑offs for latency‑sensitive workloads, shell scripting, debugging, and production troubleshooting.
• Proficiency in Python or other scripting languages for strategy development, automation, and operational tooling.
• Deep familiarity with trading system protocols (FIX, REST, WebSocket), exchange connectivity, and market data feeds.
• Solid grasp of low‑latency networking: TCP/UDP, packet and latency path analysis, dedicated network infrastructure, and kernel bypass techniques (DPDK).
• Familiarity with agentic engineering tools and concepts: LLMs, MCP APIs, AI‑First IDEs (e.g. Cursor, Claude Code), harness engineering, and workflow automation.
• Ability to make sound architectural decisions, articulate trade‑offs clearly, and guide implementation across complex systems.

Responsibilities

• Design, develop, and optimise low-latency, mission‑critical trading systems.
• Own key trading stack components end‑to‑end — from architecture through to production operation.
• Collaborate closely with quants, traders, and engineers to deliver solutions that improve trading performance and resilience.
• Maintain and evolve trading infrastructure with a focus on performance, stability, observability, and operational excellence.
• Troubleshoot complex production issues across exchange connectivity, execution, and market data handling.
• Drive engineering standards through technical leadership, code reviews, and mentoring.
• Embrace agentic engineering: leverage AI‑assisted workflows and automate operational tasks.
