• 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.
