Director, Integrated Target Design

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.
