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. What You’ll Do Industrialisation &

• Production Lines Define the technical concept of battery pack production lines, from prototype builds to niche-volume production. Develop and optimise manufacturing processes for assembly, welding, and end-of-line (EOL) testing. Ensure production solutions meet quality, safety, scalability, and manufacturability requirements. Support the definition of plant layouts, production flows, and manufacturing concepts. Provide technical support during equipment commissioning, process validation, and production ramp-up. Engineering &

• Product Design Collaboration Collaborate closely with engineering teams to ensure product designs are optimised for manufacturability. Recommend design improvements to enhance production efficiency, product quality, and cost-effectiveness. Align product requirements with manufacturing capabilities and process constraints. Support the definition of fixtures, tooling, and material handling solutions. Identify and mitigate industrialisation risks during the early stages of product development. Supplier &

• Automation Management Coordinate with equipment suppliers and automation integrators throughout project execution. Define technical requirements and specifications for manufacturing equipment and automation systems. Provide technical support during equipment manufacturing, installation, commissioning, and validation. Ensure the successful integration of automated and semi-automated production systems. Review and validate technical solutions from both manufacturing and quality perspectives. Quality, Process &





• Continuous Improvement Ensure manufacturing processes comply with applicable quality standards, including IATF 16949 or equivalent. Support the implementation of quality control, traceability, and process monitoring systems. Contribute to the definition of control plans, process validation, and production readiness activities. Drive continuous improvement initiatives to enhance process efficiency, reliability, and repeatability. Investigate and resolve manufacturing and process-related technical issues to support stable production.

Requisitos mínimos What You Bring 5+ years of experience as a Process Engineer, Manufacturing Engineer, or in a similar role within an industrial manufacturing environment. Bachelor’s or Master’s degree in Industrial, Mechanical, Electronic, Automotive Engineering, or a related discipline. Hands‑on experience with battery pack manufacturing processes, from prototype builds to low‑/medium‑volume production. Strong knowledge of assembly, welding, and end‑of‑line (EOL) testing processes.

Experience specifying and implementing industrial automation systems and production equipment. Expertise in the design and validation of tooling, fixtures, and material handling systems. Solid understanding of industrial quality systems, process validation, and manufacturing in regulated environments. Knowledge of IATF 16949 quality standards (preferred) and ISO 9001.

Monthly Town Hall

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. Inclusion & Diversity BOLD is an equal opportunity employer. We foster a culture where ideas thrive based on merit and competence, regardless of age, disability, race, religion, gender, sexual orientation, or family circumstances.
