Description
Job Purpose (Significance Of The Role & Objectives) As a Battery Prototype Engineer at Pravaig, you will play a critical role in developing Proof of Concepts (PoCs), functional prototypes, and pilot battery packs that closely resemble production-ready designs. You will work across mechanical and electrical domains to bridge the gap between R&D and production by bringing early-stage battery concepts to life in a structured, high-quality manner. Key Responsibilities And Deliverables Build PoC, functional prototypes, and pilot lots of Li-ion battery packs according to engineering documentation and production intent. Interpret and execute mechanical and electrical designs, including wiring layouts, component placements, and mechanical assemblies. Work from design documentation, schematics, and BOMs to assemble prototypes and ensure adherence to DFM (Design for Manufacturing), DFA (Design for Assembly), and DFS (Design for Serviceability) principles. Collaborate with cross-functional teams (design, thermal, BMS, supply chain) to integrate feedback and support rapid iteration. Apply knowledge of QC tools, DFMEA, process flow charts, and SOPs to support validation and design integrity throughout the build cycle. Operate tools such as torque wrenches, crimpers, spot welders, grinders, and hand/power tools with precision and safety. Understand high-voltage architecture, battery sub-systems, and electrical safety protocols for HV components and systems. Contribute to improving manufacturing feasibility by identifying design challenges during proto and pilot builds. Record accurate data on material usage, part issues, and design deviations and relay clear feedback to the R&D and design teams. Coordinate with procurement and vendors for prototype part sourcing, clarification, and on-time readiness of materials. Desired Qualifications: Required Qualification, Knowledge, and Experience 2–5 years of experience in battery pack prototyping (preferably in EV). Working knowledge of CAD tools, Microsoft Office, and reading mechanical drawings and wiring schematics. Understanding of battery assembly processes, sheet metal fabrication, welding techniques, and electrical layout standards. Comfortable multitasking between activities such as mechanical builds, electrical connections, documentation, and part coordination. Excellent verbal and written communication skills to document build processes and feedback clearly. Key Competencies Result-oriented/Goal driven. Proficiency in oral and written communication. Self-motivated, passionate about learning, and takes initiative with a problem-solving attitude. Highest level of integrity (teamwork, confidentiality, ethics, and integrity are the prerequisites for the role). Sense of ownership and pride in his/her performance and its impact on the company’s success. Show more Show less
