Job description

Job Title: Python Engineer

Location: Fully Remote (England)

Clearance: Active SC Clearance Required

Duration: 12 month contract - will extend

Project: Major Defence Programme – Secure Data Exchange Platform

Core Mission

Build and harden Python based services and data processing components that underpin a secure, scalable, distributed defence platform. Transform prototype code into operational, production ready modules.

This is a hands on engineering role requiring strong Python skills, experience in secure or mission critical environments, and the ability to contribute across backend services, data pipelines, integration layers, and automation.

Key Responsibilities

• Develop, refine, and maintain Python microservices and backend components supporting secure data exchange.
• Translate prototype logic and PoC implementations into scalable, production-grade code.
• Implement APIs, integration layers, and event-driven services aligned to agreed architecture patterns.
• Apply secure coding practices, identity controls, and data protection mechanisms.
• Contribute to CI / CD pipelines, automated testing, and integration with Infrastructure-as-Code workflows.
• Improve performance, fault tolerance, and observability across distributed services.
• Collaborate closely with solution architects, security architects, and engineering teams.
• Support validation, hardening, and iterative refinement of backend services.
• Produce technical documentation, service diagrams, and implementation notes aligned with programme standards.

Required Experience

• Strong hands on experience with Python
• Solid understanding of APIs, microservices, event-driven architectures, and messaging patterns.
• Practical experience with secure development practices, authentication / authorisation, and zero-trust principles.
• Experience working with containerised workloads (Docker; advantage if familiar with Kubernetes).
• Proficiency with CI / CD tooling, automated tests, and modern software engineering practices.
• Ability to work effectively within a senior, cross-functional architecture and engineering team.
• Strong knowledge of networking fundamentals, data structures, and secure service design.
• Comfortable working in a highly regulated, security-focused environment.
