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.

• Experience with normal-conducting RF cavity design.

• Experience with RF cavity design for Particle Accelerators.

• Experience with traveling-wave RF structures for Particle Accelerators.

• Experience with Multiphysics analysis software such ANSYS, COMSOL, ACE3P.

• Experience with the design, fabrication, and/or commissioning of high-power (kW to MW-level) RF cavities.

• Familiarity with coding languages like C++, Python, Julia, or similar.

• Knowledge of beam-cavity interaction physics.

• Knowledge of SRF for Particle Accelerators.

Environmental, Health & Safety Requirements:

• May be required to work with Compressed Gases.

• May be required to work in Oxygen Deficiency Hazard areas and Static Magnetic fields areas.

• May be required to climb Ladders.
