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 SolidWorks
  • Understanding of high-voltage systems and battery manufacturing processes
  • A practical mindset with a passion for building, testing and improving products

Why join?

  • 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

This role requires eligibility for UK Security Clearance. Apply for immediate consideration.
