Responsibilities

• Lead the Laser Engineering department, including hiring, onboarding, mentoring, and performance development of engineering staff.
• Define and own the technical roadmap for laser system development, maturation, scaling, and industrial deployment.
• Oversee the design, integration, testing, validation, and commissioning of large-scale laser systems with strong emphasis on reliability, manufacturability, repeatability, and operational performance.
• Collaborate closely with experimental physics teams to evaluate existing laser architectures, experimental results, and critical design tradeoffs.
• Review and assess current laser technologies and architectures to identify technical risks, limitations, opportunities, and areas for improvement.
• Drive technical decision-making related to future laser system architectures using experimental data, modeling results, and system-level performance analysis.
• Partner cross-functionally with optics engineering, optomechanical engineering, pulsed power, materials science, controls, manufacturing, and systems engineering teams to ensure effective communication and technical alignment.
• Translate experimental insights and lessons learned into robust engineering designs, specifications, and scalable production-ready systems.
• Lead the transition from prototype and research systems to reliable industrial-grade laser products and infrastructure.
• Establish engineering best practices, design review processes, technical documentation standards, and quality expectations for complex laser systems.
• Identify technical risks across laser development programs and drive mitigation strategies to support program execution and long-term scalability.
• Manage relationships with external vendors and partners supplying laser components, hardware, and subsystems.
• Support system troubleshooting, root cause investigations, and corrective action implementation during development and operations.
• Align laser engineering priorities with company strategy, schedules, budgets, and organizational objectives in partnership with executive leadership.
