About the company:

Xcimer Energy is a fusion energy company focused on commercializing laser-driven inertial confinement fusion, which it describes as the only scientifically validated form of fusion energy. The company is developing high-energy excimer laser systems designed to ignite fusion reactions using fuel derived from seawater and lithium, with the goal of delivering safe, clean, and affordable electricity that is cost-competitive with fossil fuels and renewables. Its mission centers on decarbonizing energy-intensive sectors such as artificial intelligence infrastructure, desalination, and industrial processes that require firm, always-on, carbon-free power. Xcimer's technical approach relies on electron-beam-pumped excimer lasers combined with a pulse compression technique called Stimulated Brillouin Scattering (SBS), which compresses microsecond laser pulses to nanosecond durations without damaging optics. In 2024 the company broke ground on Phoenix, its first prototype high-energy laser system, located in Denver, Colorado, and announced the start of its operations in June 2026. Phoenix is the first electron-beam-pumped excimer laser built in the private sector in more than two decades and validates key elements of the company's low-cost laser fusion architecture. Xcimer's longer-term target is Athena, which it describes as the world's first laser fusion power plant, expected to deliver 400 megawatts of continuous clean energy by 2035. The company has received a U.S. Department of Energy approval of its fusion power plant preconceptual design and technology roadmap milestone, and collaborates with industrial partners such as TRUMPF Laser SE. With a team of nearly 200 engineers, physicists, and business professionals, Xcimer positions itself as the most technically mature private laser fusion company.

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. Join us in powering a better world with inertial fusion!  

This is a full-time, onsite role based at our headquarters in Denver, CO.

As a Technical Project Manager, DOE Partnerships, you will support Xcimer’s public-private partnerships with the U.S. Department of Energy as we design, build, and test the experimental facilities and run the numerical investigations that lead to our fusion pilot plant. You will apply your project management skills to coordinate proposals and milestone reporting, manage cost and schedule performance, and help keep our DOE-funded work on track. As part of the Inertial Fusion Energy (IFE) program team, you will work closely with technical leads to translate program requirements into actionable schedules, track progress across concurrent workstreams, and surface risks before they threaten deliverables.

We are looking for a project manager who is comfortable coordinating both internal engineering teams and outside consultants to deliver complex technical scope, and who can pick up new technical domains quickly, going deep enough to ask the right questions and spot problems early. In this role, you’ll help manage the partnerships that take Xcimer’s fusion pilot plant from design to reality.

Equal Employment Opportunity

Xcimer Energy is proud to be an Equal Opportunity/Affirmative Action Employer and is committed to attracting, retaining, and developing a highly qualified, diverse, and dedicated work force.

Benefits are available to regular employees, including part-time and fixed-term roles, as well as interns, with eligibility varying by benefit.

Responsibilities

Manage execution of the public-private partnership between Xcimer and the Department of Energy, including milestone tracking, status reporting, and deliverable coordination.

Coordinate across technical teams, external partners, and consultants to keep DOE-funded work on track. Partner with engineering and science teams responsible for technical execution.

Coordinate the next update to the Fusion Pilot Plan (FPP) report to the DOE, including coordination with external consultants and stakeholders, to deliver an update aligned with DOE milestone requirements.

Lead establishment of cost and schedule baselines for the FPP report deliverables and milestones. Track performance against those baselines and support technical leads in keeping work within scope, cost, and schedule commitments.

Communicate accurate and timely program status, award health, risks, and reporting deadlines to Xcimer leadership.

Qualifications

Education: B.S. degree in engineering, physical sciences, project management, or a related field; advanced degree a plus.

Experience: 5+ years of project or program management experience, preferably supporting technically complex engineering, R&D, or hardware development programs.

Demonstrated experience developing and managing project schedules, milestones, dependencies, risks, and cross-functional deliverables.

Strong ability to work with technical teams and develop sufficient understanding of complex technical scope to identify dependencies, risks, and execution challenges in unfamiliar domains.

Experience coordinating multiple internal and external stakeholders across concurrent workstreams.

Experience with technical program reporting, proposal development, statements of work, milestone definitions, and deliverable management.

Strong written and verbal communication skills, including the ability to synthesize complex program information for technical teams, executives, and external stakeholders.
