Seated within our Quantitative Investment Science group, the Junior Quantitative Developer builds the core services, APIs, and shared foundations that the rest of our product is built on.

• Partner with product and design to turn requirements into clear technical designs
• Support gradual rollouts and feature flags to ship changes safely
• Instrument services with logging, metrics, and telemetry for reliability
• Document platform capabilities and APIs so teams can build with confidence

What you bring:

• Proficiency in Python and SQL for building services and working with data
• Understanding of web application architecture (frontend/backend request flow)
• Exposure to cloud platforms (Azure preferred), including containers and CI/CD pipelines
• Familiarity with API design and building clear, well-structured endpoints
• Familiarity with event-driven architecture and telemetry patterns
• Experience with collaborative git workflows (branching, pull requests, code review)
• Ability to communicate technical decisions clearly to product and non-technical collaborators
• Interest in system design and writing clean, well-typed, tested, maintainable code
• Preferred: Familiarity with React/TypeScript for frontend work, familiarity with feature flags for controlled rollouts, exposure to financial products
