Job summary

Keyrock seeks a Senior Rust Engineer with deep trading systems experience and strong AWS knowledge to join our Capital Markets division. You will own core trading infrastructure, design scalable components, and drive improvements in performance and reliability.

You will join a fully remote, global team with European time‑zone alignment and participate in high‑impact projects that push the frontier of digital assets trading systems.

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).
• 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, kernel bypass techniques (DPDK).
• Familiarity with agentic engineering tools and concepts: LLMs, MCP APIs, AI‑First IDEs, 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 principles: AI‑assisted workflows and automation of operational tasks.
• Contribute to functional, component, and production‑readiness testing for critical trading components.
