NanoX is building the world's first commercially viable lithium-free semi-solid state battery modules — and we're looking for a hands-on CTO to take our technology from validated cells to market-ready packs. This isn't a strategy-only role. We need a builder.
Responsibilities
- Design and development of battery pack and module architectures (high-voltage and low-voltage)
- Cell-to-pack integration engineering for our proprietary semi-solid state chemistry
- BMS design and integration, thermal management, and electrical safety systems
- Busbar design, laser/ultrasonic welding processes, and tab-to-busbar interconnect engineering
- Taking products from prototype → pilot → commercial production
- Building and leading a lean technical team across four countries (USA, India, Netherlands, South Korea)
- Working directly with contract manufacturers, vendor qualification, and supply chain partners
What We're Looking For
- 10+ years in battery systems engineering — you've personally designed and built packs and modules
- Deep knowledge of HV and LV pack architectures, series/parallel configurations, and safety systems
- Hands-on experience with BMS (hardware and firmware), thermal simulation, and pack-level testing
- Proven track record with cell integration, busbar routing, welding processes, and DFM
- Familiarity with battery certifications: UL810A, UL 1973, UN 38.3, IEC 62619, and equivalent standards
- Startup DNA — you're comfortable being an IC on Monday and presenting to investors on Friday
- Bonus: Experience with non-lithium or next-generation chemistries — semi-solid state, sodium-ion, or similar
What We Offer
- Co-founder-level impact at an early-stage deep tech startup
- Meaningful equity stake (details discussed with serious candidates)
- The opportunity to shape an entirely new battery chemistry's path to market
- A global team with active operations in the US, India, Netherlands, and South Korea
- Direct collaboration with the founding team and Tier 1 defense and commercial customers
About NanoX
NanoX is not another lithium-ion company. We're proving that lithium-free, semi-solid state batteries are commercially viable — safer, NDAA-compliant, and built for the markets that need an alternative to Chinese-dominated supply chains. We need a CTO who can turn breakthrough cells into products the world can use.
