Software Engineer, Low-Latency Systems
- Employment Type: Full-time
- Experience Level: senior-level (7–10 years)
About the Role
We are hiring a Software Engineer, Low-Latency Systems to design and optimize the core infrastructure powering our algorithmic trading systems. In this role, you will work on latency-critical execution paths where nanoseconds, cache lines, memory layout, and network behavior matter.
This is a hands-on engineering position for someone who enjoys building high-performance systems and reasoning deeply about correctness, throughput, and tail latency. Prior trading domain experience is helpful but not required—we value engineering depth and systems thinking above all else.
What You’ll Do (Responsibilities)
- Build Core Infrastructure: Design, develop, and maintain low-latency components including order routing, market data handling, and execution pipelines.
- Optimize Performance: Profile and optimize critical code paths to minimize throughput and tail latency.
- Collaborate Across Teams: Work closely with quant and trading teams to translate complex strategy requirements into highly efficient infrastructure primitives.
- Drive System Design: Contribute to architectural decisions around threading models, memory layout, and network stack configurations.
- Ensure Reliability: Improve observability and operational performance across trading infrastructure. Participate in on-call rotations, incident response, and post-mortems to keep systems running smoothly.
What We’re Looking For (Requirements)
- Experience: 7 to 10 years of professional experience in systems engineering, with a demonstrable focus on low-latency systems or high-performance computing (HPC).
- Language Proficiency: Strong, production-level proficiency in Rust and/or C++.
- Systems Depth: Comfort reasoning about memory management, lock-free data structures, compiler behavior, and CPU-level performance.
- Tooling: Experience using Linux performance tooling such as perf, flamegraphs, strace, or similar tools.
- Networking Fundamentals: Solid understanding of network stack behavior, including TCP, UDP, multicast, and kernel bypass.
- Problem Solving: Ability to debug complex production issues and optimize systems under real-world constraints.
Nice to Have (Bonus Points)
- Prior exposure to trading systems, market data feeds, or exchange connectivity.
- Familiarity with financial market protocols (e.g., FIX, ITCH, OUCH).
- Experience with low-latency networking technologies like DPDK, RDMA, or kernel bypass.
- Familiarity with co-location environments and latency-sensitive infrastructure.
Culture & Fit
We are looking for an engineer who takes ownership, thrives in ambiguous and fast-moving environments, and holds an incredibly high bar for correctness and performance. If you love drilling down into the lowest levels of software to squeeze out maximum efficiency, we want to hear from you.
