Job Title: BESS Integration Engineer
Location: Trichy
About Frigate: Frigate is a fast-growing B2B manufacturing execution company. We take industrial products from development to serial production—handling New Product Development (NPD), contract manufacturing, and second-source programs. Powered by a proprietary digital platform, we coordinate a network of 33 committed manufacturing partners selected from over 900 qualified Indian suppliers, serving customers across 19 export markets. Our core focus segments include energy, power electronics, EV charging, and precision manufacturing.
What You Will Do
- Own end-to-end integration of a 100 to 200 kW C&I BESS: module-to-rack assembly, busbar and DC wiring, LV/AC wiring, BMS installation and configuration, thermal system fit-out, fire suppression fit-out
- Define the assembly sequence, torque specs, wiring plan, and quality checkpoints; build the SOPs and checklists this program will scale on
- Lead FAT: insulation resistance, hipot, continuity, IP verification, functional and charge/discharge testing, with full documentation
- Work with our enclosure fabrication vendors on design-for-assembly feedback
- Train and supervise one fitter/electrician during the build
- Support commissioning at the customer site
Must have
- 5 to 10 years in lithium battery pack or ESS manufacturing/integration, with at least 2 years above single-pack level (rack, cabinet, or container)
- You have personally assembled, wired, and commissioned battery systems. This is a hands-on role, not a supervisory one. Be ready to walk us through torque specs, busbar prep, and BMS CAN faults you have resolved yourself
- Working knowledge of LFP systems, BMS commissioning, and safety standards (IEC 62619, UL1973; exposure to UL9540/NFPA 855 a plus)
- Comfortable with FAT documentation discipline: test records, dimensional reports, traceability
Good to have
- Experience at a BESS or pack OEM (Delta, Amara Raja, Cygni, Exicom, Grinntech, Okaya, HBL, Nexcharge or similar)
- HV safety certification, C&I or grid-connected system exposure
- Tamil helpful, not mandatory
Why this role
You build the program from unit one and write its playbook. Successful pilot converts this into a full-time leadership seat on a new business line, not a maintenance job on someone else's line.
