Build and maintain data pipelines and integrations across engineering, manufacturing, procurement, ERP, PLM, and business systems. Develop monitoring, dashboards, automation, and data governance practices that improve operational decision-making. Collaborate with cross-functional teams to translate requirements into durable tools, document system ownership and lineage, and support evolving organizational needs. This is a full-time, onsite role in Denver, Colorado.

Designs and operates Xcimer Energy’s internal developer platform across data pipelines, warehouses, dashboards, research environments, HPC simulation access, and cloud infrastructure. Builds platform services, APIs, control planes, infrastructure-as-code, observability, and secure scalable systems across on-premises and cloud environments. Mentors engineers, documents operational practices, manages cloud costs, leads modernization, and translates research and engineering needs into reliable tooling.

Lead architecture and development of Python-based software for scientific analysis, visualization, data pipelines, machine learning, and internal workflows. Collaborate with researchers and engineers to deliver scalable production systems, integrate HPC and legacy C++ or Fortran code, optimize parallel and GPU-enabled workloads, and establish testing, documentation, CI/CD, and containerization practices. Mentor engineers and provide technical direction across research and experimental software projects.

Lead non-sequential ray-trace analysis and stray light mitigation for high-energy DUV laser systems using FRED. Model and validate mechanical features (baffles, beam dumps), identify hot spots and fringing, write scripts to automate simulations and data processing, and collaborate with optical, mechanical, and materials teams to meet system-level stray light requirements.

Create and run multi-physics and electromagnetic models and simulations of pulsed power electrical and mechanical systems. Collaborate with design teams to optimize designs, plan validation experiments, and integrate simulation-driven improvements into manufacturing-ready designs.

Lead HR strategy and operations for a rapidly scaling fusion energy company. Build and mentor the HR organization, drive workforce planning, organizational design, leadership development, total rewards, HR systems, compliance, employee relations, and people analytics to support multi-site growth and commercialization.
