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
- 25 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.
