We are looking for an experienced Software Engineer to work on designing and developing cutting-edge battery inspection technology. We are developing an on-premise metrology tool that integrates with factory systems, as well as cloud systems for ingesting and analyzing the collected data. You will be instrumental in creating and analyzing requirements as well as designing, implementing, testing, and delivering software that is modular, scalable, robust, and meets customer requirements. You will work closely with our product development and engineering teams on a variety of projects.

On a typical day, you may integrate a new data acquisition (hardware) component into our toolchain, build endpoints for IoT devices to communicate with one another, integrate process monitoring and traceability tools onto deployed devices, or design a user interface. You value active listening, thoughtful questions, and data-driven discussions. You are comfortable with gathering and distilling information to drive the direction of open-ended projects. The ideal candidate will approach this work with a mixture of intellectual curiosity, thoughtful creativity, and methodical rigor. You will get great satisfaction from seeing people do great things with your work, and, above all, are excited to solve hard problems that have a positive impact on the world’s clean energy future. This is a potentially hybrid position with expectations of in-office work for the first 6 months.
