Join Xcimer, a company on a mission to revolutionize energy through commercially viable inertial fusion. As a Senior Platform Engineer, you will design and build the systems and tools that enable researchers and engineers to work efficiently. This hands-on role involves architecting and writing platform services, managing cloud infrastructure, and mentoring junior engineers. You will have a direct impact on the future of energy and work closely with physicists, controls engineers, and software architects.

Responsibilities

  • Design and ship systems, services, and tooling that enable researchers and engineers to work efficiently.
  • Build and own the internal developer platform, ensuring researchers and engineers can provision what they need quickly.
  • Architect and write platform services, control planes, APIs, and data-pipeline frameworks, ensuring reliability and scalability.
  • A track record of designing systems for reliability, observability, and scale
  • Clear communication, including explaining technical tradeoffs to non-technical colleagues
  • Experience mentoring engineers and leading cross-functional projects

Requirements

  • Strong software engineering fundamentals. Proficiency in Python, Rust, and/or C++
  • Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee of granted asylum
  • Experience building internal platforms or tooling that measurably improved team productivity
  • Experience: 7+ years of experience in platform, infrastructure, or software engineering, including building internal tools or platforms used by other engineers
  • 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
  • Education: Bachelor's degree in Computer Science, Engineering, Physics, Applied Mathematics, or related field; advanced degree preferred
  • Familiarity with Open OnDemand or similar research computing portals

Preferred

  • Experience with containerization and orchestration (Kubernetes, Docker, or similar)
  • Experience building data platforms, data warehouses, or analytics and dashboard infrastructure
  • Prior experience in scientific computing or research environments
  • Experience with secure enclave architectures, identity management (OIDC, LDAP), or export-controlled data
  • Experience managing and optimizing cloud infrastructure
  • Domain background in manufacturing, experimental physics, or fusion energy. We don't require it — strong generalists ramp quickly here — but a head start is welcome
