Job description

xLight is on a mission to build the next-generation light source to power the future of semiconductor manufacturing. Our approach harnesses the power of free-electron lasers, utilizing accelerator-based methods in use globally at scientific user facilities. Extending this technology, we are developing an industrial-grade light source, engineered for continuous operation, to meet the sophisticated demands of next-gen patterning, metrology, and inspection applications.

We are seeking a highly skilled and motivated Cryogenic Engineering Leader to build and manage a talented engineering team responsible for designing, constructing, and operating a complex 2K cryogenic system supporting our superconducting electron accelerator. As the technical leader of this effort, you will play a critical role in guiding the team through all project phases, from design through commissioning, while mentoring engineers at all levels.

Key Responsibilities

• Team Leadership & Development: Build, hire, and lead a high-performing cryogenic engineering team. Mentor engineers and technicians, provide technical guidance, and foster a culture of excellence, collaboration, and continuous improvement.
• System Design & Development: Lead the design and development of the 2 Kelvin cryogenic plant, including specifications, component selection, system integration, and technical validation. Ensure all designs meet performance, safety, and reliability requirements.
• Project Management: Manage all aspects of the project including scheduling, budgeting, resource allocation, risk management, and stakeholder communication. Ensure timely and successful completion while maintaining technical quality.
• Installation & Commissioning: Lead on-site activities during the Albany convergence phases. Oversee installation, commissioning, and operational setup of the cryogenic system with your team, including performance verification, troubleshooting, and final validation.
• Cross-Functional Collaboration: Work closely with other teams and departments, as well as external partners and vendors, to ensure alignment and coordination throughout the project lifecycle.
• Documentation & Reporting: Maintain accurate documentation of design specifications, test procedures, operational guidelines, and lessons learned. Provide regular technical and progress reports to stakeholders.

Required Qualifications

• Bachelor's degree or higher in Mechanical Engineering, Cryogenic Engineering, or a related field (advanced degree preferred)
• Minimum 15 years of professional experience in cryogenic engineering with a strong background in the design, construction, and operation of cryogenic systems
• Demonstrated leadership experience managing technical teams and complex engineering projects from conception through completion
• Strong communication and interpersonal skills with the ability to lead, mentor, and collaborate effectively across teams and organizational levels
• Proficiency in CAD software (Siemens NX preferred) and other engineering tools for design and analysis
• Knowledge of relevant industry standards and regulations related to cryogenic systems and safety protocols
• Ability to work independently, prioritize complex tasks, and manage multiple workstreams in a fast-paced, dynamic environment

Highly Desired Qualifications

• Experience with superconducting technology and particle accelerator systems
• Familiarity with electron accelerator component design or related scientific instrumentation
• Experience designing, building, or commissioning capital equipment in semiconductor or related manufacturing environments
• Track record of successfully transitioning team members from project-based roles to ongoing operational responsibilities

Work Location & Travel

This position is remote-first, with flexibility to work from anywhere. However, the role requires your team to converge in Albany, NY for critical project phases:

• Installation phase (estimated 4-6 months)
• Commissioning and operational setup (estimated 4-6 months)
• Final system checkout and validation

We provide accommodation and logistical support during convergence periods. Candidates must be willing to relocate temporarily to Albany during these critical project phases.

What We Offer

• 100% Company-funded health insurance for employee
• Company funded Life Insurance and disability insurance
• 401k contribution. 100% up to 3% of compensation, plus 50% match between 3% and 5%. Immediately vested.
• Flexible Paid Time-Off, Sick leave and Company Holidays
