Job Description

Senior Python Software Engineer Cambridge Hybrid Competitive Salary
We're working with an innovative technology company seeking a Senior Python Software Engineer to build and optimise high-performance data processing systems in a production-focused environment.
This role is centred on software engineering rather than modelling, with a strong emphasis on clean code, Test-Driven Development (TDD), and scalable data processing.

Key Responsibilities
  • Develop and maintain production-grade Python applications.
  • Build high-throughput data processing pipelines handling large datasets on local server infrastructure.
  • Design and implement robust multithreaded and multiprocessing solutions.
  • Write clean, maintainable code within a TDD environment.
  • Optimise performance across CPU, memory, and I/O intensive workloads.
Essential Experience
  • Strong commercial Python development experience.
  • Expert knowledge of multithreading, multiprocessing, and concurrency.
  • Proven track record working in a Test-Driven Development environment.
  • Experience building scalable, production-focused systems.
  • Strong understanding of software performance optimisation and clean code principles.
  • Experience working with big data and high-volume processing on localised infrastructure.
Desirable
  • Experience with C++ or Rust.
  • Distributed systems or parallel processing experience.
  • Background in scientific, engineering, or industrial software environments.
This is an excellent opportunity for an engineer who enjoys building reliable, high-performance software and solving complex data and concurrency challenges.
