Senior SRF Engineer

Brookhaven National Laboratory • Ridge, NY

17d • $113,050 - $218,150 • Hybrid

About The Position

Brookhaven National Laboratory (BNL) is the building site for the Electron-Ion Collider (EIC), a one-of-a-kind nuclear physics research facility. The EIC will be a discovery machine for unlocking the secrets of the “glue” that binds the building blocks of visible matter in the universe. The machine design is based on the existing and highly optimized RHIC Ion-Ion collider. It will consist of two intersecting accelerators, one producing an intense beam of electrons, the other a beam of protons or heavier atomic nuclei which are steered into collisions. Beyond sparking scientific discoveries in a new frontier of fundamental physics, the Electron-Ion Collider will trigger technological breakthroughs that have broad-ranging impact on human health and national challenges. Position Description BNL’s Electron-Ion Collider (EIC) directorate has an opening in the RF Group for a Senior SRF Engineer with experience in surface processing and clean assembly of SRF cavities and equipment. In this role, you will oversee and optimize all cleanroom operations related to the preparation, assembly, and integration of SRF cavities and associated components. The work scope will include upgrades and maintenance of the current class 10 cleanroom and the class 100 cleanroom, as well as planning, surface preparations, and clean assemblies of SRF cavities and associated components for the EIC Project. This position has a high level of interaction with an international and multicultural scientific community.

Requirements

• Bachelor’s degree in mechanical engineering, chemical engineering, materials science, applied physics, or a related field plus 7+ years of related experience, OR Master’s degree in related field plus 6+ years of related experience.
• At least five (5) years’ experience in class 10-100 cleanroom operations and clean assembly of SRF cavities and components.
• Experience with SRF cavity processing techniques such as HPR and vacuum bakeout.
• Familiarity with ISO cleanroom standards, environmental monitoring, and gowning protocols.
• Ability to read and interpret detailed mechanical drawings and 3D models of SRF systems and components.
• Experience developing and maintaining technical documentation, procedures, travelers, and quality reports.
• Leadership skills with the ability to manage teams and coordinate across disciplines.
• Excellent written and oral communication skills.
• Attention to detail and commitment to procedural discipline.

Nice To Haves

• At least ten (10) years of experience in SRF cleanroom operations and accelerator-related hardware.
• Experience with SRF cryomodule assembly, integration, or operational support.
• Experience with SRF cavity processing techniques such buffered chemical polishing, electropolishing, and nitrogen infusion and doping.
• Experience designing tooling and fixtures for clean processing and assembly of SRF components.
• Knowledge of materials compatibility for ultra-high vacuum and cryogenic applications.
• Familiarity with cleanroom certification processes and environmental monitoring systems.
• Familiarity with the production of thin film coatings used in RF/SRF cavities (e.g. TiN).
• Familiarity with surface characterization techniques (e.g. XPS, SEM).
• Project management experience, including scheduling and resource planning tools (e.g., MS Project).
• Professional Engineering (PE) license.
• Demonstrated ability to mentor and train technicians in SRF cleanroom best practices.

Responsibilities

• Lead and coordinate all SRF cleanroom operations, including cavity preparation, high-pressure rinsing (HPR), clean assembly, and leak checking in ISO class 10–100 environments.
• Oversee upgrades, maintenance, certification, and validation of SRF cleanroom facilities to meet EIC project requirements.
• Serve as the technical interface with external vendors and partners for SRF component processing (e.g., BCP, EP), including coordination and follow-up.
• Develop, implement, and enforce cleanroom procedures and quality documentation to ensure particle-free handling and assembly of SRF components.
• Optimize surface preparation, cleaning, assembly, and vacuum practices to improve cavity yield, performance, and schedule efficiency.
• Supervise and manage technicians and engineers responsible for cleanroom operations and SRF cavity and cryomodule assembly.
• Ensure compliance of cleanroom operations with laboratory safety standards, national codes, and environmental, health, and safety requirements.
• Contribute to project planning, budgeting, and execution of SRF systems scope for the EIC in collaboration with RF Group leadership and project management.

Benefits

• Brookhaven National Laboratory is committed to providing fair, equitable and competitive compensation.
• Brookhaven National Laboratory is committed to employee success and we believe that a comprehensive employee benefits program is an important and meaningful part of the compensation employees receive.
