Research Engineer, AI/ML

Responsibilities

• Turn messy financial data and ambiguous problems into working AI products, starting with simple baselines and adding complexity only when it earns its keep
• Build evaluations that reflect real user outcomes, then use error analysis, ablations, and production feedback to make the system better
• Make practical tradeoffs across model quality, cost, latency, determinism, reliability, and maintainability

Requirements

• Experience shipping ML or AI systems end-to-end, from data and evaluation through production
• Comfort making progress with noisy data, weak labels, incomplete specifications, and imperfect supervision
• Strong Python skills and the ability to contribute to production software; TypeScript or modern web application experience is a plus
• We welcome a range of backgrounds. Successful candidates will typically have one of the following:
• A bachelor’s degree in a relevant quantitative field plus 3+ years of relevant industry or applied research experience
• A relevant master’s degree plus 1+ year of relevant industry or applied research experience
• A relevant PhD; doctoral research counts as relevant experience, with 3 years of substantive doctoral research considered equivalent to the experience above

The Job

• You’ll work on a fast-moving AI team, owning problems from initial exploration through production.
• Partner closely with product and engineering to build AI features that take real work off finance teams’ plates

What You Bring

• Strong statistical and machine learning fundamentals, with good judgment about when the answer is classical ML, an LLM, agents, or something in between
• Experience across several of: classical ML, embeddings, retrieval and reranking, similarity search, model evaluation, LLM applications, and agentic systems

Experience and education

Equivalent practical experience demonstrated through shipped systems, independent research, open-source work, or another nontraditional path

How We Work

We’re a small team, so everyone has a hand in deciding what to build and making it work in the real world.

We ship, learn from real usage, and iterate

• We make assumptions explicit, follow the evidence, and communicate tradeoffs clearly
• We stick with hard problems and welcome better ideas, regardless of where they come from
• We help where the team needs us, even when it falls outside our immediate scope
• We collaborate closely in person five days a week
• No one gets extra points for making the solution more complicated than the problem.
• Even if you don’t meet every qualification, we encourage you to apply. We care most about curiosity, craft, judgment, and drive.

Competitive compensation and equity

Unlimited PTO

• Up to 100% employer covered monthly healthcare premium (medical, dental, vision)
