Senior Developer I - Full Stack Python Engineer (Fixed Income Technology)

About this role

We are seeking a Senior Full Stack Engineer to build modern, intuitive web applications and a microservices-based backend that powers Fixed Income investment workflows (trading, portfolio construction, risk and analytics). This is a hands-on, highly collaborative role partnering closely with portfolio managers, quantitative teams and research to deliver scalable, production-ready platforms.

You will design and develop front-end user experiences as well as backend services and APIs, including event-driven components leveraging Kafka. Success in this role requires a builder mindset—someone who can take ambiguous problems from concept to production—paired with strong engineering judgment around service boundaries, API design, testing strategy and operational readiness. You should be comfortable working directly with investment stakeholders and iterating quickly while maintaining high quality.

What you’ll do (Responsibilities)

- Partner with investment and research stakeholders to clarify requirements, define scope, and translate needs into technical designs and deliverables.
- Design, build, and maintain interactive web applications (React) used by investment professionals.
- Build RESTful APIs and microservices (Python/Flask/FastAPI) to support data access, business logic, and workflow orchestration.
- Implement event-driven patterns using Kafka (producers/consumers, topic design, partitions/consumer groups, error handling/retries, and delivery semantics where applicable).
- Contribute to data platform work: modeling, pipelines, validation, transformation, and integration with analytics/reporting use cases (e.g., Snowflake + SQL).
- Own end-to-end delivery: design, development, code review, testing, deployment, and production support.
- Improve engineering quality and operability through standards for testing, documentation, CI/CD, monitoring, and alerting.
- Mentor engineers and lead by example in design reviews, pull requests, and production readiness practices.
