Salary Range: 241000 to 284000 (Currency: USD) (Pay period: per-year-salary)

Xcimer Energy is advancing Inertial Fusion Energy (IFE) by combining decades of scientific progress with a breakthrough laser architecture designed for practical and scalable fusion power. Our mission is to deploy commercial fusion plants quickly enough to accelerate global decarbonization, and also reduc the cost of electricity. Backed by leading investors, Xcimer brings together experts in laser physics, fusion science, and advanced manufacturing with a proven history of rapid execution. With a uniquely positioned team and technology, we are urgently working to deliver clean, abundant fusion energy with the speed to address climate change. Please join us in building a future powered by laser driven inertial confinement fusion (ICF).

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

As the Director of Integrated Target Design at Xcimer, you will lead the interdisciplinary group of scientists and engineers that optimize all aspects of target physics for our new laser architecture. Your main responsibilities will be to guide efforts in advanced simulations and experiments, as well as the recruitment, mentoring, and development of the team. As a technical expert, you will provide day-to-day guidance to your team and participate in cross-function discussions across ICF disciplines. In close partnership with the program leads, you will translate high-level priorities and objectives into actionable plans, and build the culture and collaborations needed to reach the highest possible levels of fusion performance. At Xcimer, you can expect the resources and opportunity to build on decades of prior work in ICF and realize its ultimate potential for producing energy.

The ideal candidate would have significant understanding of inertial confinement fusion (ICF), the associated workflows, and existing high-energy-density-facilities and institutions.

Responsibilities

Build, grow, and lead the Integrated Target Design group, including recruiting, hiring, onboarding, managing, mentoring, and the professional development of staff.

Convert program priorities into detailed work scopes, schedules, and task assignments for the team.

Participate as a technical authority in cross‑functional discussions with laser engineering, target fabrication, chamber engineering, diagnostics, etc.

Provide day-to-day technical guidance to team members in implosion physics, LPI, symmetry control, and energy coupling strategies.

Review and validate team outputs for technical quality and consistency Contribute to technical collaborations with national labs, universities, external vendors, and testing facilities.

Establish department-wide practices, documentation standards, review processes, and quality control appropriate for industrial fusion systems.

Success Measures

An Integrated Design team with high measures of performance, strong collaborations, and very clear priorities.

High-quality outputs delivered on schedule and aligned with program goals.

Strong integration of target physics and implosion design work into experimental platforms that drive system, element, and program level decisions.

Effective recruiting, mentoring, and development of internal capabilities.

Consistent delivery of work scopes tied to physics risks and their resolution.

Qualifications

Ph.D. in Physics or Engineering, or a related technical field, with knowledge of ICF.

Demonstrated ability to lead and develop scientific or technical teams.

Strong written and verbal communication skills, including the ability to convey complex arguments to diverse staff in a matrixed organization.

Ability to manage execution in a fast-moving, interdisciplinary environment, with evolving priorities.

Must be a U.S. citizen or national, U.S. permanent resident, or lawfully admitted as a refugee or granted asylum.

Desired

Deep expertise in inertial confinement fusion, capsule and hohlraum design, laser-plasma instabilities, hydrodynamics, or a related field.

Familiarity with radiation‑hydrodynamic modeling workflows, methods in physics validation, and developing or supporting experimental platforms at HED facilities (NIF, OMEGA, Z, or similar).

Experience in multi‑institutional experimental collaborations.

Familiarity with topics of interest to IFE including target fabrication, DT filling, cryogenic handling, and/or target injection and delivery.

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. Xcimer Energy hires and promotes people on the basis of their qualifications, performance, and abilities.
