The Mission
Club JURA is Zaizi's dedicated club for Defence. We are looking for a heavyweight Head of Engineering to lead our technical mission. You will lead the technical mission, ensuring our solutions are architected with the holistic rigour of systems engineering while providing high-level technical oversight for modern, cloud-native software delivery.
Reporting to the Club Exec, you will be the technical linchpin of Club JURA, translating high-level mission objectives into rigorous engineering roadmaps, while providing the data-backed assurance and performance reporting necessary to de-risk our most complex sovereign programmes.

You will own the architectural integrity of the "System of Systems," providing overwatching of design, integration, and test (I&T) technical oversight across both hardware-software interfaces and pure software platforms Standards & Compliance: Own the application of established standards from ISO 15288 to Def-Stan 00-55 / IEC 61508. You will provide the engineering oversight and process rigour required to enhance quality in high-security and safety-critical domains Software Oversight: While focussed on the system, you will provide technical oversight for software engineering teams. You'll ensure that modern software practices (Agile, DevSecOps, CI/CD) are harmonised with the overall system V-lifecycle and safety requirements Performance & Board Reporting: Establish and track KPIs for engineering performance. You will provide the Club Exec and Zaizi Board with transparent, data-driven reporting on technical risk, system maturity, and delivery health Team Shaping & Governance: Recruit, mentor, and lead elite engineering teams.

You will use your experience across multiple defence domains to ensure our bids are technically sound, commercially viable, and compliant with relevant standards Intelligent Problem Solving: Where applicable, identify and architect AI-driven solutions for complex defence challenges. You will ensure that AI and Machine Learning are integrated into systems engineering to solve specific mission problems—such as predictive maintenance or autonomous ISTAR—ensuring they are fit for purpose and operationally sound Internal Collaboration: Work with our in-house AI team and provide practical, frontline-focused input to help shape internal IRAD, ensuring our research has real-world utility in contested environments
