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
- •Ownership & Reliability – Take full responsibility for your work. Deliver high-quality service, meet deadlines, and follow through on commitments. Anticipate and proactively address potential issues before they arise.
