Power Electronics

Assistant Engineer- Power Electronics

Bengaluru   |   Full Time

Log 9 Materials is using its core competence in Graphene nanotechnology to develop advanced energy storage technologies from electrode materials, cell to pack level. Our Rapid Charging Battery packs (Read more) solve the challenges in adoption for the 2W and 3W electric vehicle platforms while our Aluminum Fuel Cell technology (Read more) is targeted towards the electrification of long haul, heavier vehicles.

Electrification of vehicles specially for commercial use ranging from 2W, 3W to LCVs to HCVs will not only have a significant positive impact on the environment, but it will lead to huge cost savings as well. However, different vehicle platforms have unique requirements and hence there cannot be a one-type fit all battery technology. 

In this endeavor, we are building a team of Engineers and Technocrats to make India energy Independent.

Log 9 team stands for Innovation, Intellect, Integrity, Initiative and Individual Growth. Hence, we are looking for people who identify with the same set of values.

Unique chance to work at the cutting edge of technology in India, building solutions to solve global energy storage challenges.
