Full Stack / DevOps Engineer

Lightium is building next-generation photonic integrated circuits on thin-film lithium niobate (TFLN). As we scale, we need someone to own the day-to-day operation and development of the systems that keep our engineering and operations running, from cloud infrastructure and CI/CD pipelines to enterprise platform integrations and internal tooling.

Position Summary

This is a hands-on, execution-focused role. The focus is on backend development and infrastructure. You’ll be the person who makes things work, keeps them running, and continuously improves them. We want someone who is equally comfortable spinning up a cloud environment, writing a Python integration script, and experimenting with LLM-based tooling to automate a tedious workflow. If you are hungry to build real things in a fast-moving environment, this role was designed for you.
