The Voleon GroupFull Time
Senior (5 to 8 years)
Candidates should possess 4+ years of backend engineering experience with a strong focus on Python, specifically with frameworks like FastAPI or Django. They must demonstrate the ability to design and operate distributed systems capable of handling high throughput and low latency, along with experience utilizing message queues/streams such as Apache Kafka or Google Pub/Sub, and caching layers like Redis. Familiarity with Elixir/Erlang or other functional stacks is preferred, and a pragmatic approach to considering edge cases and failure modes, particularly within financial or real-time systems, is required.
The Backend Engineer - Risk & Trading will design and implement Python backend services that power real-time risk management and trading operations, building scalable infrastructure for pricing engines, market creation, settlement, and exposure management. They will integrate with Elixir services via gRPC/REST, Kafka, and Redis, architect distributed systems on Google Cloud Platform (GCP) using Pub/Sub, Cloud Run/Kubernetes, and BigQuery, and develop robust monitoring, alerting, and CI/CD pipelines. Furthermore, they will collaborate with data scientists on model deployment and optimize end-to-end latency, and own projects from ideation through production, making thoughtful trade-offs in ambiguous, high-stakes environments.
