• Customer behaviour modelling, pricing strategy and product development.

• Collaborating with product teams to translate quantitative insights into customer-facing decisions

Qualifications

• 4+ years of relevant quantitative or engineering experience, with strong Python development skills.

• Quantitative background - maths, physics, engineering or finance - you can read a model and reason about correctness.

• Clear communicator who can work cross-functionally with other quants, analysts, traders, product managers and engineers.

• Experience taking quantitative work into production and owning its ongoing validation, monitoring and improvement.

• For the Researcher track:

• Strong experience in quantitative research or modelling in finance, with depth in an area such as pricing, forecasting, risk or trading.

• Ability to translate an open-ended financial problem into a quantitative model, choose appropriate statistical or numerical methods, and explain assumptions and limitations.

• Experience designing backtests and out-of-sample validation, accounting for data leakage, transaction costs and changing market conditions.

For the Developer track:

Strong experience with microservices, databases, and production infrastructure

Experience with streaming systems, real-time data pipelines, or event-driven architectures (Kafka, Flink, Redis etc.)

Experience with testing, monitoring, and debugging complex systems under load

We’re people without borders — without judgement or prejudice, too. We want to work with the best people, no matter their background. So if you’re passionate about learning new things and keen to join our mission, you’ll fit right in.

Also, qualifications aren’t that important to us. If you’ve got great experience, and you’re great at articulating your thinking, we’d like to hear from you.

And because we believe that diverse teams build better products, we’d especially love to hear from you if you’re from an under-represented demographic
