Role

We are looking for an experienced Senior Software Engineer (with a DevOps focus) to work on supporting the software infrastructure for our 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 these data. You will be instrumental in defining the roadmap and implementation strategy for our software releases and infrastructure upgrades. You will be curating and defining requirements – delivering and releasing software that meets internal and external customer requirements, including scalability and repeatability. You will work closely with our software, data and product management teams on a variety of projects.

We are looking for a developer who wants to set the foundation for devops-related architectural decisions to simplify our in-house and external software releases. However, there are many hats to wear based on need – you might define a data analysis pipeline using AWS or integrate a new data acquisition hardware component into our toolchain. 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.
