Liminal’s mission is to accelerate the clean energy transition by improving the cost, quality, and reliability of battery manufacturing. We do this by providing customers with better analytics and insights during production. Our breakthrough EchoStat® platform uses ultrasound and machine learning technology to supply customers with the information needed to accelerate production ramp-up, improve productivity and reliability, and detect critical defects early. We will be deploying our first fully-automated process inspection solutions in a major cell manufacturing factory in late 2023.
Liminal is based in Emeryville, California. Our investors include ArcTern Ventures, Ecosystem Integrity Fund, Chrysalix Ventures, Volta Energy Technologies and Northvolt. We also have funding support from the Department of Energy’s ARPA-E, the National Science Foundation and California Energy Commission.

About the role
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.
