Rust Engineer - Trading Systems

Keyrock is a leading digital asset company specializing in market making, trading, and DeFi ecosystem growth, with a focus on Rust development for trading systems.

Location: European time zones

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

Requirements

• 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

Benefits

• A competitive salary package
• Autonomy in your time management thanks to flexible working hours and the opportunity to work remotely
• The freedom to create your own entrepreneurial experience by being part of a team of people in search of excellence
