About
Amazon is guided by four principles: customer obsession rather than competitor focus, passion for invention, commitment to operational excellence, and long-term thinking. We are driven by the excitement of building technologies, inventing products, and providing services that change lives. We embrace new ways of doing things, make decisions quickly, and are not afraid to fail. We have the scope and capabilities of a large company, and the spirit and heart of a small one.
Together, Amazonians research and develop new technologies from Amazon Web Services to Alexa on behalf of our customers: shoppers, sellers, content creators, and developers around the world.
Our mission is to be Earth's most customer-centric company. Our actions, goals, projects, programs, and inventions begin and end with the customer top of mind.
You'll also hear us say that at Amazon, it's always "Day 1." What do we mean? That our approach remains the same as it was on Amazon's very first day - to make smart, fast decisions, stay nimble, invent, and focus on delighting our customers.

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
