• Leading the design and development of Python-based software systems in a high-security setting
• Working closely with data scientists, analysts, and engineering teams to deliver scalable, reliable solutions
• Architecting secure applications and services in line with defence-grade standards
• Mentoring developers and enforcing best practices across code, testing, and deployment
• Integrating machine learning models and real-time data pipelines where applicable
• Collaborating with stakeholders to gather requirements and showcase technical progress
• Experience in secure or regulated industries (Defence, Government, Aerospace, etc.)
• Solid grasp of CI/CD, containerisation (Docker/Kubernetes), and cloud or on-premise deployments
• Ability to lead technical discussions, reviews, and deliverables across cross-functional teams
• Familiarity with Agile/Scrum delivery
• Active DV Clearance
