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. Responsibilities DevOps & Cloud Infrastructure Manage and maintain cloud infrastructure on AWS and/or GCP, including compute, storage, and networking. Build, maintain, and improve CI/CD pipelines to support reliable and repeatable deployments of internal software and tooling. Implement infrastructure-as-code practices to ensure environments are version-controlled, reproducible, and auditable. Monitor system health, cyber security, access control, respond to incidents, and implement fixes and preventive measures to maximize uptime and reliability. Manage development and production environments and enforce sensible promotion and deployment workflows. Enterprise Systems Support & Integration Support the day-to-day operation and configuration of Lightium’s enterprise platforms: Aras Innovator (PLM), Oracle NetSuite (ERP), and MES. Support, maintain, and scale our corporate IT infrastructure, such as selection and implementation of network hardware, servers, storage, etc. Develop and maintain integration pipelines and API connectors (in Python, C#, etc.) that move data reliably between systems.
