About the role
- DRW is a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world.
- Headquartered in Chicago with offices throughout the U.S., Canada, Europe, and Asia, we trade a variety of asset classes including Fixed Income, ETFs, Equities, FX, Commodities and Energy across all major global markets.
Responsibilities
- Build and operate agentic harnesses - tools, context management, evals, guardrails - that do real work against our data and infrastructure, and own their quality in production.
- Own full-stack performance from the network edge to in-memory stores - instrumenting, monitoring, and debugging production systems alongside operations, keeping SLOs razor-sharp.
- Lead green-field initiatives, design reviews, and post-mortems.
Requirements
- A preference, not a gate - deep systems experience in another serious language transfers.
- Deep knowledge of network programming and protocols - TCP/UDP/IP, DNS, BGP, HTTP(S), WebSocket, QUIC.
- Bachelor's or Master's in Computer Science, Data Science, Mathematics, or a related discipline.
- We have also leveraged our expertise and technology to expand into three non-traditional strategies: real estate, venture capital and cryptoassets.
- 3-5 years building real-time or data-intensive systems (we weigh trajectory and depth over the exact number).
- Depth with LLMs, not just usage - how these models actually behave (context and its failure modes, tool use, structured output, cost/latency trade-offs, bounding hallucination) and how to build the harness around one: tools, memory, retries, evals, human-in-the-loop boundaries. Bring something real you shipped and can walk us through end to end, including what broke.
- Strong engineering fundamentals in Python, Go, or Rust. A preference, not a gate - deep systems experience in another serious language transfers.
- Rapid POCs to production - validate statistical significance, iterate quickly, ship, and explain the result to technical and non-technical audiences alike.
- Who Thrives Here
- This is a competitive, high-stakes environment, and we're looking for people who want that
- rather than tolerate it. You'll likely recognize yourself here if:
- You want problems that are genuinely hard and measurable - where the scoreboard is real and public inside the team.
- You move fast without being sloppy, and you'd rather ship, measure, and correct than deliberate indefinitely.
- You're comfortable being wrong quickly and in public, and you update rather than defend.
Compensation
- Competitive salary, matching RRSP
Benefits
- Continuous learning through paid postgraduate degrees, Dev Lightning talks, online learning support and 1 on 1 language tutoring with Berlitz
- Bi-weekly social activities, monthly wellness plan, on-site weekly massages, and games room
