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.
