Location: Templecombe, United Kingdom

Thales is a global technology leader with more than 83,000 employees on five continents. With over 7,500 people in the UK, operating across defence, space, aerospace, and digital security, we help build a future we can all trust. Thales supports the security and stability of our nation by providing extraordinary technology to our customers, as well as delivering social value to the UK with our products and services.

Our purpose is to deliver trusted underwater sensing and decision advantage, working hand‑in‑hand with navies around the world to safeguard people and nurture global security. Our work spans four sectors: Mine Countermeasures, Anti‑Submarine Warfare, Services and Future Capabilities.

Our Underwater Systems (UWS) is looking for a Project Design Authority—a technical leader who possesses the rare blend of engineering rigor, strategic vision, and the "natural authority" to lead complex sonar projects from concept to sea.

As the primary technical interface with our customers, you won’t just be part of the team; you will be the ultimate arbiter of solution integrity, ensuring our anti-submarine warfare and mine-hunting technologies are compliant, safe, and world-beating.

• Risk & Strategy: Navigate "Make vs. Buy" decisions and mitigate technical risks throughout the bid and project lifecycle.

• Verification: Sign off on the final integration, verification, and validation (IV&V) of complex systems.

About You:

You are an experienced engineer who has moved beyond "doing" and into the realm of authorizing and influencing. You thrive in high-stakes environments where your decisions have a direct impact on national security.

Your DNA:

• Technical Depth: Significant expertise in Sonar Systems, Signal Processing, or Hardware, with a deep understanding of the full systems engineering lifecycle.

• Natural Authority: A proven track record as a PDA or Lead Engineer on large-scale, complex defense projects.

• Strategic Thinker: You don’t just solve the problem; you consider the business case, the supportability, and the long‑term footprint.

• Communicator: You can command a room of experts or simplify complex technical hurdles for stakeholders with ease.
