Software Engineer, Backend

Why you should join us

• We’re building a research lab with a real-time feedback loop: the financial markets.
• Our edge isn’t secret data or microwaves - it’s the speed at which we iterate and learn.
• We’re starting in options, where complexity (read: opportunity) is high and most firms still rely on human intuition.
• Join a frontier team with over a decade of experience in quant trading. These aren’t logos from internships - we’ve started and led teams at Optiver, DRW, and Argo AI.
• Real ownership, fast iteration, zero red tape. We’re literally putting our $ where our mouth is.

What you’ll do

• Build the core systems for ingesting data, training models, simulating strategies, and running them live - from scratch.
• Design infra that helps researchers move fast: feature stores, experiment tracking, feedback loops, monitoring.
• Work side-by-side with the founders to test predictions in real markets and learn from every outcome - good and bad.
• Make calls on architecture, tools, and priorities. This isn’t a “here’s the roadmap” kind of role. You hold the pencil.

What we’re looking for

• You’ve built real systems: distributed compute, ML pipelines, or infra that powers actual decisions.
• You’re fluent in languages like Python, C++, Rust, and you know your way around cloud, containers, and databases.
• You care about iteration speed, clean abstractions, and systems that can hold up under pressure.
• You think like a builder and have empathy for researchers. Bonus if you’ve worn both hats.
• Zero finance experience required - just curiosity, drive, and the desire to go deep on a hard problem.

You’ll be given the autonomy to do some of the best work of your life.
