Quantitative Researcher

What you will do

  • Research alpha signals and trading strategies.
  • Apply ML, statistics, and rigorous data analysis to portfolio construction and optimization.
  • Write research the team can act on, and iterate fast.

What we look for

  • Strong background in math, stats, CS, physics, or a related quantitative field.
  • Statistical intuition and breadth across ML models and techniques.
  • Self-confident and self-motivated.
  • Prior research experience in crypto or finance is a plus.

Senior Quantitative Engineer

What you will do

  • Build our time-stream dataflow engine in Rust — the core our research and trading run on.
  • Design trading systems that are simple yet powerful — and robust and fast because of it.
  • Use AI throughout your development process, with humans in control of every design decision.
  • Work alongside engineers with 15+ years of experience.

What we look for

  • A strong background in Rust or C++, databases, parallelism, and algorithms. Ordering incoming execution events so a crash recovers to a consistent state doesn’t scare you.
  • You reach for the simple solution, not the fashionable tool — Postgres over Kafka, until scale truly demands otherwise.
  • A taste for correctness, minimalism, and elegance. Your functions do one thing well, and corner cases fall out of the design rather than a tangle of if/else.
  • Experience writing maintainable, testable code. We build software to last, so you design testability and composability into the architecture from the start.

Internship

What you will do

  • Take one project from blank page to presented result.
  • Pair with a researcher or an engineer.
  • Ship something we keep using.

What we look for

  • Evidence of high ownership and proactiveness.
  • A quantitative background — math, science, engineering, or similar.
  • Available for a 10–12 week summer, in person.
