Weapon System Product Lead

At Hypersonica, we're redefining what's possible in European defence technology. We exist to deliver speed, resilience, and technological independence at a pace that sets a new standard. We are a small, elite team working on problems that matter, and solving them fast.

By joining Hypersonica, you're not stepping into a predefined role. You're joining a talent dense environment where every individual shapes the direction of the company. Our philosophy is to hire a small number of exceptional people with broad, deep technical capability, strong judgement, and the ability to operate autonomously.

We hire for talent, not rigid boxes. This role represents a business need, but the way it evolves will be shaped by the individual. If you've achieved what others said was impossible, or you bring a unique combination of skills that doesn't fit a traditional mould, we want to hear from you. The work you do here directly contributes to Europe's technological independence.

• Own the product direction and lifecycle coherence of one of our weapon systems currently in development, ensuring it evolves into a capable, reliable, producible, maintainable, and supportable product. 
• Build and maintain the product roadmap, translating operational needs, technical maturity, test evidence, and business priorities into clear capability spirals, releases, and product decisions. 
• Act as the product authority across engineering, manufacturing, test & safety, quality, programmes, and ILS, ensuring a shared understanding of the product, its intended use, and its next priorities. 
• Own the product baseline, variants, versioning, and configuration intent, ensuring that engineering changes are assessed before adoption. 
• Set clear product priorities and trade-offs with engineering, balancing capability, safety, reliability, cost, schedule, maturity, production, and through-life sustainability. 
• Engage with relevant customer and operator stakeholders to validate priorities and usage requirements. 
• Use evidence from integration, test, production, maintenance, and operator feedback to shape the next development spirals and focus investment on the changes that create the greatest product and operational value. 
• Ensure reliability, maintainability, producibility, supportability, transportability, and safety from the outset. Work closely with the ILS organisation, retaining ownership of the resulting product trade-offs and evolution. 
• Establish lean product-management structures and decision routines where needed, keeping the product moving without adding process for its own sake. 
• Make sound decisions under real technical and delivery ambiguity, recognise when a decision requires wider expertise or escalation, and step into unowned product problems rather than waiting for assignment. 

• You have five or more years' experience leading the development and evolution of complex hardware products or systems, ideally in defence, aerospace, or a similarly demanding environment.
• An understanding of the full product lifecycle, from requirements and design through integration, test, production, in-service support, and product improvement.
• A technically credible with engineering teams and can turn complex technical detail into clear product priorities, decisions, and trade-offs.
• Experience managing product baselines, variants, configuration, and the impact of engineering changes in a controlled development environment.
• You understand how safety, reliability, maintainability, producibility, supportability, and cost shape a successful product, not just its technical performance.
• Experience leading effectively across disciplines, creating alignment without needing formal authority over every contributor.
• Comfortable taking ownership in ambiguity, making considered decisions with incomplete information, and escalating issues where the decision or risk exceeds your authority.
• You bring a pragmatic, hands-on approach, building only the structure needed to keep the product moving, and continuously improving ways of working rather than working problems.
• British citizenship is required due to the security requirements of the role. You must be eligible to obtain and maintain the required UK security clearance.

At Hypersonica, every hire raises the bar. We are deliberately small, intensely capable, and deeply mission-driven. If this role feels like a strong fit, or if you believe you bring something exceptional that goes beyond the description, we encourage you to apply.

Hypersonica is an equal-opportunity employer and assesses candidates solely on merit, capability, and potential.

You can apply directly to this role or reach out to Nathan Sweeney, Head of Talent. We review every application and aim to respond to all candidates within two weeks, whether the answer is yes or no.
