Senior Test Engineer

At BOLD, we design and build the next generation of high-performance battery systems for the world’s most demanding industries — from Formula 1 and hypercars to aerospace, marine and defense. Our mission: to deliver energy systems where every millisecond and every degree matter.


As a Senior Test Engineer, you will play a key role in validating the performance, safety and reliability of our high-voltage battery systems. You’ll design and execute advanced test plans, analyse data, and collaborate with cross-functional teams to turn engineering concepts into proven, high-performing energy solutions.

If you’re passionate about testing, validation and pushing energy systems to their limits, this is your chance to make a real impact on the future of electrification through rigorous engineering and innovation.


What You’ll Do

  • Plan, execute and analyse validation tests to ensure our high-voltage battery systems meet the highest standards of performance, safety and reliability.
  • Develop and maintain Design Verification Plans (DVPs), linking system requirements to test activities and ensuring complete coverage throughout the validation process.
  • Set up and operate test benches and measurement systems — including battery cyclers, climatic chambers, vibration and shock rigs, EMC and abuse test setups.
  • Use tools like CANalyzer, CANoe, PCAN Explorer, Python, Concerto or vSignalyzer to collect, process and interpret test data.
  • Collaborate with design, systems, hardware and software engineers to identify issues, propose solutions and verify design improvements.
  • Apply and adapt testing standards and safety regulations from automotive, motorsport, aerospace and defense industries.
  • Contribute to continuous improvement by refining test methodologies, introducing automation or data management tools, and supporting the development of new test infrastructure.
  • Act as a technical reference within the Testing team, guiding and supporting junior engineers in developing their testing skills and ensuring consistent, high-quality validation practices.

About BOLD

At Bold, we’re a diverse, international team with backgrounds in automotive, motorsport, aerospace, defense and aviation.

We combine creativity and engineering rigour to deliver high-performance, safe and sustainable energy systems for the world’s most demanding applications.

We operate through two divisions:

  • BOLD Applied Engineering (BAE )– Provides top-tier professional engineering services, primarily to elite motorsport teams (especially Formula 1), in areas such as composite design, mechanical engineering, aerodynamics and systems integration. This expertise is transferred directly to complex defence sector programmes.
  • BOLD Technology (BT) – Designs, develops and manufactures high-voltage battery systems and electric propulsion system components for defence applications, tactical vehicles, military platforms, aviation and advanced mobility. BOLD is an international benchmark in defence electrification, supplying systems to United States Army programmes and collaborating with leading defence primes in the US and Europe.

Together, BT and BAE allow BOLD to offer a unique blend of technology, engineering services, and execution capability to elite customers operating at the highest levels of performance.
