Xcimer is seeking a Principal Adaptive OpticsEngineer to technically lead the design, specification, procurement, and integration of a high-speed custom adaptive optics system for advanced laser beamlines. This role will serve as the technical authority for adaptive optics within the organization and will work closely with vendors, internal engineering teams, and system stakeholders to deliver a fully integrated and operational system. We are looking for our engineers and scientists to apply their technical expertise, problem solving skills, and dedication to quality to positively impact the future of energy!

Technical Leadership and System Architecture

Serve as the technical lead for the adaptive optics system, from requirements definition through integration and commissioning

Define system level requirements and performance budgets for fast adaptive optics, including wavefront sensors, deformable mirrors, real time controllers, and diagnostics

Lead trade studies and architecture decisions for high bandwidth, low latency correction systems integrated into laser or photon beamlines

Ensure system designs meet performance, reliability, and operability requirements

Vendor Engagement and Procurement

Lead technical engagement with commercial and research vendors delivering adaptive optics components and subsystems

Develop technical specifications, statements of work, and acceptance criteria for externally supplied hardware and software

Oversee vendor design reviews, factory acceptance tests, and delivery milestones

Act as the primary technical interface for resolving performance, schedule, and integration issues with suppliers

Integration, Test, and Commissioning

Lead assembly, integration, and test of the adaptive optics system within the beamline environment

Define laboratory and in situ test plans to validate performance and closed loop operation

Work closely with beamline, controls, and laser system teams to ensure seamless system integration

Support commissioning activities and transition to reliable operations

Department Growth and Future Management

Establish technical standards, documentation practices, and development workflows for the Adaptive Optics group

Mentor and guide engineers and scientists working on adaptive optics and wavefront control topics

Participate in hiring and onboarding as the group expands

Education: Advanced degree in optics, physics, electrical engineering, or a closely related field

Experience: 8+ years of experience in adaptive optics, wavefront sensing and control, or closely related high speed optical control systems

Demonstrated hands on experience working with laser beams, including propagation, beam quality, wavefront control, and interaction with real optical hardware

Experience developing or integrating adaptive optics specifically for laser-based systems

Proven experience specifying, integrating, and testing fast adaptive optics hardware and real time control systems in laboratory or operational environments

Hands-on experience with deformable mirrors, wavefront sensors, and high bandwidth feedback control

Proven ability to work directly with external vendors on custom optical and electro optical systems

Strong written and verbal communication skills for technical reviews, requirements definition, and cross team coordination

Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee of granted asylum

Highly preferred: experience with directed energy systems, including high power or high intensity laser platforms

Experience delivering custom adaptive optics systems from concept through commissioning

Prior experience mentoring engineers or leading technical teams

Familiarity with real time software, FPGA based control, or low latency computing architectures

Experience in laboratory and operational environments requiring high reliability and uptime
