Software Engineer Research

We are a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world. We value autonomy and the ability to quickly pivot to capture opportunities so we operate using our own capital and trading at our own risk.

We operate with respect curiosity and open minds. The people who thrive here share our belief that its not just what we do that mattersits how we do it. We are not aplace of high expectations integrity innovation and a willingness to challenge consensus.

We build the systems that turn real-world events into actionable signal at low latencyand high reliability in a trading environment where being right second is the same asbeing wrong. This role sits at the intersection of research and infrastructure: youllform hypotheses prove them with rapid analysis and then build the production systemsthat act on them.

We also build with LLMs as a first-class part of the toolchain not a side people who do well here are the ones who can wield an agentic harness as fluently as
they wield a profiler and who know exactly where each one stops being trustworthy.

How You Will Make an Impact

Discovery & Research

• Expand our event-driven strategy across exchange feeds market news social media and infrastructure telemetry.
• Spin up rapid analyses in Python/Jupyter to assess signal quality and turn what you find into system improvements.

LLM & Agentic Systems

• 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.
• Apply LLMs where they genuinely win (extraction classification triage research acceleration) and make the call tonotuse one where they dont.

Infrastructure & Technical Leadership

• 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.

What You Bring

Core

• 35 yearsbuilding 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.
• Deep knowledge of network programming and protocols TCP/UDP/IP DNS BGP HTTP(S) WebSocket QUIC.
• Rapid POCs to production validate statistical significance iterate quickly ship and explain the result to technical and non-technical audiences alike.
• Bachelors or Masters in Computer Science Data Science Mathematics or a related discipline.

Who Thrives Here

This is a competitive high-stakes environment and were looking for people who want that
rather than tolerate it. Youll 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 youd rather ship measure and correct than deliberate indefinitely.
• Youre comfortable being wrong quickly and in public and you update rather than defend.

Bonus Points

• Depth in the current LLM ecosystem agent frameworks MCP RAG architectures eval tooling or local/self-hosted inference.
• Demonstrated success squeezing latency from NGINX Envoy or custom load-balancing layers.
• Background in high-pressure domains trading floors esports competitive athletics or hackathons.
• Open-source contributions technical blogging or conference speaking.

What we have to offer you:

• Mentorship with experienced software developers database administrators and technical project managers
• Continuous learning through paid postgraduate degrees Dev Lightning talks online learning support and 1 on 1 language tutoring with Berlitz
• 40 hours of paid volunteer work at the organization of your choice
• Bi-weekly social activities monthly wellness plan on-site weekly massages and games room
• Enjoy daily catered meals (breakfast and lunch) with unlimited snacks and beverages
• Competitive salary matching RRSP
