We're developing an excimer-based laser fusion architecture to commercialize safe, affordable fusion energy while advancing national security. We employ nearly 200 people, mostly in our Denver headquarters. Backed by Prelude Ventures.
About the role
Xcimer Energy leverages decades of research on Inertial Fusion Energy (IFE) combined with groundbreaking new laser architecture. Our mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. Xcimer has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by leading investors, Xcimer is uniquely positioned to deliver limitless, clean, fusion power to combat climate change.
What they're looking for
- Education: Bachelor's degree in Computer Science, Engineering, Physics, Applied Mathematics, or related field, advanced degree preferred
- Experience: 7+ years of experience in platform, infrastructure, or software engineering, including building internal tools or platforms used by other engineers
- Strong software engineering fundamentals. Proficiency in Python, Rust, and/or C++
- Experience building internal platforms or tooling that measurably improved team productivity
- Hands-on experience with Linux and infrastructure automation (Ansible, Terraform, or equivalent)
- Experience with cloud infrastructure (AWS/GCP/Azure). Familiarity with HPC clusters and job scheduling is a plus

As a Senior Platform Engineer you will design and ship the systems, services, and paved-path tooling that let researchers and engineers move fast. The platform spans data analysis pipelines, the data warehouse, dashboards, research code environments, and the friendly interfaces that expose HPC simulation to non-specialists: a broad surface where great engineering directly accelerates discovery.
This is a hands-on, high-impact role. You will architect and write systems, treat internal tooling as a product with real users, mentor junior engineers, and make deliberate tradeoffs between speed and robustness in an R&D environment where both matter....
