Cleanroom Engineer Jobs (NOW HIRING)

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.

• 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.

Required Knowledge, Skills, and Abilities:

• 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.

Preferred Knowledge, Skills, and Abilities:

• At least ten (10) years of experience in SRF cleanroom operations and accelerator-related hardware.

• 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.

Environmental, Health & Safety Requirements:

• May be required to work with Compressed Gases.
• May be required to work in Confined Spaces, Oxygen Deficiency Hazard areas and Static Magnetic fields areas.
• May be required to climb Ladders and operate Cranes.
• May be required to become a qualified Radiation Worker and work in radiation areas.
