Battery Integration Engineer

Maidenhead | Onsite | 9-Day Fortnight | Salary Negotiable

Most battery engineering roles involve optimising an existing product.

This role is about creating the next one.

We're supporting a pioneering company developing some of the most advanced UAV platforms operating anywhere in the world today.

As part of a growing Concept Development team, you'll take ownership of battery systems from initial requirements through to flight-ready hardware.

Unlike many organisations where battery engineers sit in a narrow specialist function, here you'll work closely with propulsion, avionics, mechanical and flight test teams, seeing your designs progress rapidly from concept to airborne reality.

What you'll be doing:

• Designing and integrating advanced battery pack solutions from concept through to production
• Developing battery architectures using pouch cell technologies
• Creating and executing test and validation programmes
• Building and evaluating prototype battery systems
• Working on thermal management, packaging and high-voltage integration challenges
• Collaborating closely with suppliers and multidisciplinary engineering teams
• Supporting the development of next-generation energy solutions for autonomous aircraft

We're interested in engineers who bring:

• Strong battery pack design and cell integration experience
• Hands-on experience with pouch cells
• Knowledge of thermal management and battery safety principles
• Experience with CAD tools such as Solid Works
• Understanding of high-voltage systems and battery manufacturing processes
• A practical mindset with a passion for building, testing and improving products
• Work on technology where battery performance is mission critical
• See your designs move rapidly from concept to flight testing
• Join a highly engineering-led environment with significant autonomy
• Work alongside experts across avionics, propulsion and autonomy
• 9-day fortnight with a long weekend every other week
• Healthcare, bonus scheme, pension and share incentive plan
• Salary is negotiable and will reflect experience and capability
