• Experience with Dremels, sanders, files, deburring tools, or similar fabrication and rework tools.

• Soldering experience preferred; ability to learn and consistently perform a product‑specific soldering technique.

• Familiarity with adhesives, surface preparation, clamping, bonded assemblies, or torque‑controlled fastening is preferred.

• Ability to read and follow drawings, work instructions, rework instructions, and visual standards.

• Experience with busbars, busplates, battery components, sheet‑metal assemblies, or industrial equipment is a plus.

• Strong mechanical aptitude and ability to perform precise, repeatable work.

• Strong attention to detail, safety, cleanliness, and workmanship.

• Basic documentation and data‑entry skills.

• Effective communication and ability to work collaboratively with technicians, engineers, and manufacturing teams.

Physical Requirements

• Ability to sit or stand and perform repetitive assembly tasks for extended periods.

• Ability to lift up to 50 pounds with or without reasonable accommodation.

• Ability to handle and position large components safely.

• Ability to perform tasks requiring dexterity, precision, and hand‑eye coordination.

• Ability to safely operate soldering equipment, hand tools, power tools, fixtures, and rotary tools.
