About the role

Senior Rust Engineer with trading systems experience and strong AWS knowledge to join Keyrock's Capital Markets division, focusing on designing, building, and operating low-latency, mission-critical trading systems in a fully remote, European-timezone environment.

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

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
