Job Description – Proto/Pilot Senior Manager (Mechanical & Electrical) – BESS
Role Summary
The Proto/Pilot Senior Manager – Mechanical & Electrical (BESS) will lead prototype development, pilot production, mechanical and electrical integration, validation support, and manufacturing readiness for Battery Energy Storage System (BESS) products at a 5 GWh / 6.25 GWh manufacturing facility .
The role will act as a critical bridge between Engineering, Validation, Quality, Supply Chain, and Manufacturing to ensure successful transition from prototype development to pilot production and scalable mass manufacturing.
Key Job Responsibilities
Prototype & Pilot Build Leadership
- Lead end-to-end prototype and pilot build activities for BESS products.
- Manage engineering builds, design validation builds, pre-production builds, and pilot production builds.
- Develop and execute prototype build plans, schedules, resource requirements, and milestones.
- Drive rapid problem-solving and design iterations during prototype and pilot stages.




- Ensure prototype builds are completed within defined timelines, quality, safety, and cost targets.
- Lead teams of engineers, technicians, and manufacturing personnel involved in prototype and pilot builds.

Mechanical Prototype & System Integration
- Lead mechanical integration of battery modules, packs, racks, enclosures, and containerized BESS systems.
- Oversee assembly of structural frames, battery housings, cooling systems, mechanical interfaces, and related components.
- Identify and resolve mechanical fitment, tolerance, interference, fastening, sealing, and structural issues.
- Ensure proper mechanical integration across the complete BESS architecture.
- Support thermal and cooling system integration, including interfaces between mechanical and thermal components.
- Drive Design for Manufacturability (DFM) and Design for Assembly (DFA) improvements.
- Work with mechanical design teams to incorporate prototype and pilot build learnings in
