Job summary

Keyrock is seeking a Senior Rust Engineer with deep trading systems experience and strong AWS knowledge to join our Capital Markets division. You will own high‑impact trading infrastructure, set technical direction, and drive continuous improvements in performance and reliability within a globally distributed, predominantly remote team across European time zones.

Applicants should have production‑grade Rust expertise, hands‑on work in HFT or market making, plus strong Linux/AWS skills.

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, 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 principles: leverage AI-assisted workflows, drive automation of operational tasks, and help evolve the team's agentic tooling
• Contribute to functional, component, and production-readiness testing for critical trading components
