Optical Engineer

Focused Energy is a fusion energy startup with the goal of generating unlimited clean energy to responsibly meet future global demand. With the use and commercialization of laser-induced inertial fusion a clean and highly efficient power generation technology is coming within reach suitable to ensure a secure and scalable future energy supply.

We are seeking a skilled and driven Optical Engineer to design analyze and help realize the next generation of high-energy and high-average-power laser systems that underpin Focused Energys fusion this role you will be responsible for turning advanced optical concepts into robust manufacturable and operable experimental and production laser systems.

Your work will directly enable the performance stability and scalability of our fusion laser infrastructure ensuring that optical designs meet extreme power precision and reliability requirements while remaining practical to build integrate and operate.

What youll do

Optical System Design : Design model and optimize complex optical systems for high-energy and high-average-power laser applications balancing performance robustness and manufacturability.

Simulation & Analysis : Use advanced optical modeling tools (e.g. Zemax / OpticStudio) to perform ray tracing tolerance analysis stray light analysis and wavefront propagation to predict and validate system behavior.

Performance Specification : Define detailed optical specifications including component selection materials coatings and tolerances to meet demanding power fluence and stability requirements.

Integration & Commissioning : Partner closely with technicians laser engineers and mechanical and electrical teams during assembly alignment testing and commissioning of optical systems troubleshooting issues as they arise.

System Optimization : Identify and resolve performance limitations related to aberrations thermal effects alignment sensitivity and stray light to ensure stable repeatable operation at high power.

Documentation & Communication : Produce high-quality technical documentation analyses and design reviews to support internal development knowledge sharing and external collaboration.

Cross-Functional Collaboration : Work across disciplines to ensure optical designs integrate cleanly into larger laser mechanical electrical vacuum and control system architectures.

Who you are

A degree in Optical Engineering Physics Electrical Engineering or a related field with professional experience designing and analyzing optical systems for laser or photonics applications.

Deep hands-on experience with Zemax (OpticStudio) or comparable optical design and simulation tools including tolerance and stray light analysis.

Strong understanding of classical optics Gaussian beam propagation laser physics and material behavior under high-intensity or high-fluence conditions.
