Hiring outlook
Critical
India's gigafactory wave needs 4,000+ cell engineers by 2030.
Role overview
Cell engineers sit at the foundational layer of any battery program — every design choice they make ripples through module, pack, BMS and thermal. The role is split roughly 60% lab work (coin-cell builds, electrolyte trials, formation cycles) and 40% data analysis and supplier dialogue.
India's gigafactory push (Ola, Reliance, Tata, Exide) plus a dozen well-funded cell startups (Log9, ePropelled, Bharat Energy Storage) means cell engineers can pick from venture-backed and OEM-led environments.
