About the Role

The opportunity

We are working exclusively with a technology-driven trading firm at the cutting edge of global financial markets. The team is small, senior, and embedded directly on the trading floor - your work has immediate, measurable impact from day one.

They are looking for a Software Engineer fluent in Python or Rust (ideally both) to take full ownership of features end-to-end, from design through delivery and into production. This is a predominantly in-office role (4–5 days per week) in London.

What we’re looking for

  • 2–5+ years in a software engineering role, with a track record of delivering production-quality features independently
  • Strong proficiency in Python and/or Rust; willingness to pick up complementary languages as needed
  • Systems programming fundamentals: memory management, concurrency, safe and performant code
  • Test-Driven Development discipline - unit, integration, and E2E tests as a standard part of your workflow
  • REST API experience: designing, building, and consuming APIs including authentication, versioning, and error handling
  • Source control and CI/CD: GitHub, Azure DevOps, or GitLab; branching strategies and pipeline contribution
  • Experience in cloud-hosted environments - Azure preferred
  • Strong ownership mindset; comfortable engaging directly with stakeholders without a middleman
  • Clear written and verbal communication in English

Nice to have

  • Async Rust (Tokio / async-std) and high-throughput concurrent services
  • Familiarity with C, C++, or other systems languages; FFI bridging experience
  • Prior exposure to financial services or fintech
  • Containerised environments (Docker / Kubernetes)
  • Message-based architectures (Kafka, NATS) or gRPC / protobuf
  • Experience collaborating with globally distributed teams
