In this role, you will be the hands-on expert responsible for supporting the development, prototyping, and validation of our next-generation battery systems. You will bridge the gap between design and reality by building prototype battery packs, executing critical testing procedures, and managing day-to-day operations of our battery lab. If you thrive in a fast-paced R&D environment and love working directly with cutting-edge energy storage systems, we want you on our team. Key Responsibilities + Prototype Battery Builds: Assemble, rework, and modify prototype battery packs and modules from the ground up, working directly with battery cells, modules, connector assemblies and printed circuit boards (PCBs). + Precision Joining & Assembly: Perform precision spot welding, resistance welding, and soldering to interconnect cells and integrate Low-Voltage (LV) and High-Voltage (HV) wiring harnesses and connectors. + Quality & Safety Testing: Support critical validation tests, including pressure/vacuum leak testing for sealed enclosures, insulation testing, and continuity checks. + Lab Management & Safety: Own the maintenance, and safety compliance of the battery build and test laboratory. Ensure all equipment is calibrated, standard operating procedures (SOPs) are followed, and safety protocols for hazardous materials/high-voltage are strictly enforced. + Test Execution & Data Logging: Set up, monitor, and manage battery test equipment (cyclers, environmental chambers, data loggers) and document build processes and test anomalies clearly for the engineering team. ## Related Videos - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [Crypto-secure Data Management with In-Database Blockchain](https://www.wearedevelopers.com/videos/632-crypto-secure-data-management-with-in-database-blockchain) - [Empowering Democratic Processes: Building a Hybrid Voting Platform](https://www.wearedevelopers.com/videos/1163-empowering-democratic-processes-building-a-hybrid-voting-platform) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [A Technical Introduction to Bitcoin's 2nd Layer- The Lightning Network](https://www.wearedevelopers.com/videos/15-a-technical-introduction-to-bitcoin-s-2nd-layer-the-lightning-network) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Best Coding Boot Camps in Germany](https://www.wearedevelopers.com/magazine/237-best-coding-boot-camps-in-germany) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [6 Emerging Technologies We’ll Learn About in 2025](https://www.wearedevelopers.com/magazine/381-6-emerging-technologies-we-ll-learn-about-in-2025)
