Mechanical Engineer

Argonne National Laboratory•Lemont, IL

About The Position

We are searching for a junior engineer to join the engineering team supporting the Medium Energy Physics and Fundamental Symmetry research groups at Argonne National Laboratory. The engineering team supports the full experimental program of both groups, including the design and construction of particle detectors and atomic physics instrumentation. The main focus over the next five years will be the design and construction of the Barrel Imaging Calorimeter for the future Electron-Ion Collider and the expansion of the Argonne TRACER center, alongside other smaller experimental efforts. The position includes structured overlap with an outgoing senior engineer and is designed to grow toward a long-term lead engineering role supporting both research groups.

Requirements

B.S. in mechanical, structural, or related engineering required.
Proficiency with mechanical CAD software (Solidworks, Creo, Inventor, or equivalent).
Working knowledge of high- and ultra-high-vacuum systems.
Oral and written communication skills.
Experience with a breadth of laboratory equipment.
Working proficiency with modern engineering analysis tools, including FEA (ANSYS, COMSOL, SolidWorks Simulation, or equivalent).
Basic fluency with the physics context of detector and atomic-physics work, enough to communicate design tradeoffs with physicists (specialist physics or data-analysis expertise is not required).
Mechanical aptitude and demonstrated hands-on work (academic, internship, or professional).

Nice To Haves

M.S. in engineering OR experience in an accelerator or physics research laboratory preferred.
Familiarity with laser and optical systems, and radiation and beam detectors to support detector R&D.

Responsibilities

Carry out mechanical design and hands-on build/assembly for large particle detector systems and other systems for physics experiments.
Support the full experimental program of both research groups, including the design and construction of particle detectors and atomic physics instrumentation.
Focus on the design and construction of the Barrel Imaging Calorimeter for the future Electron-Ion Collider and the expansion of the Argonne TRACER center.
Interact with research scientists, laboratory support staff, and external collaborators or vendors.
Model Argonne’s Core Values: Impact, Safety, Respect, Integrity, and Teamwork.
