Role: Build Quality Engineer (Battery, Product & Integration)
Department: New Product Development Location: Bengaluru, India Experience: 5+ Years
Your Team:
You'll be working with New Product Development — a group that runs on coffee and an infectious passion for building products that have never been built before. Our Flexible Energy Stack consists of the e^pack (battery pack) and e^pump (charging station), which unlock 15-minute rapid charging.
Our philosophy:
Break. Believe. Build.
Break stuff, break assumptions, break the thumb rule.
Believe in the team, the process, and through failures.
Build fast, build passionately, build to simplify.
Own it like you mean it.
What you’ll own:
We are seeking a Build Quality Engineer to own factory-floor quality during battery, product, and vehicle-integration prototype builds — catching deviations early, driving root cause on build issues, and certifying builds ready for testing.
The ideal candidate is hands-on, detail-obsessed, and comfortable being the last line of defense before a build moves to test.
What you’ll do:
Prototype Build Quality
- Own quality oversight during battery and vehicle-integration prototype assembly builds
- Identify and document issues as they occur during assembly
- Capture part and build deviations and log them for tracking
RCA & Feedback
- Drive root cause analysis on issues identified during prototype builds
- Provide assembly feedback to the design and process quality engineers
Build Certification
- Certify assemblies and vehicles as ready before they proceed to testing
- Support closure of build-related non-conformances before test handoff
Cross-functional Collaboration
- Interface with the design and process quality teams on recurring build issues
- Escalate patterns and systemic issues to the Function Lead
What you’ll bring:
- Education qualification
- B.E. / B.Tech in Mechanical Engineering or related field
- 1-3 years of experience in prototype or manufacturing builds
- Working knowledge of deviation tracking and basic RCA tools
- Comfortable working hands-on, daily, on the factory floor
Preferred Experience (Good to Have):
- Experience in EV or automotive prototype build environments
- Exposure to both battery and vehicle assembly (vehicle preferred)
What matters to us:
- Quality of work
- Structured problem-solving
- Dissatisfaction with mediocre work
- Ability to multi-task and handle a dynamic working environment
- Resilient attitude to bounce back after failing
