Stealth-mode Battery Startup • Fremont, CA

3d • Onsite

About The Position

The Mechanical Assembly and Rework Technician will support the assembly, modification, and rework of large battery busplates and related components. Initial work will focus on connector soldering, adhesive-backed assembly, fixture operation, part cleaning, and tab-removal rework. As the role expands, the technician may support additional prototype and low-volume production activities involving large-format mechanical and electromechanical assemblies. This is a hands-on role requiring strong mechanical aptitude, attention to detail, and consistent execution of documented processes.

Requirements

• High school diploma or equivalent required.
• Hands-on experience in mechanical assembly, manufacturing, fabrication, production rework, equipment assembly, or a similar environment.
• Experience using hand tools, power tools, assembly fixtures, and basic measuring equipment.
• Experience with Dremels, sanders, files, deburring tools, or similar fabrication and rework tools.
• Ability to read and follow drawings, work instructions, rework instructions, and visual standards.
• 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.

Nice To Haves

• Associate degree, trade-school training, or technical certification preferred.
• 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.
• Experience with busbars, busplates, battery components, sheet-metal assemblies, or industrial equipment is a plus.

Responsibilities

• Solder electrical connectors onto large busplates using established techniques and work instructions.
• Assemble busplates and related components using adhesives, compression fixtures, fasteners, brackets, and hand tools.
• Support prototype builds, engineering trials, and low-volume production of large-format mechanical and electromechanical assemblies.
• Perform controlled rework and part modifications using Dremels, sanders, files, deburring tools, and similar equipment.
• Prepare and clean surfaces and completed parts to meet manufacturing cleanliness requirements.
• Inspect assemblies for dimensions, alignment, fit, surface condition, and overall workmanship using basic measuring tools.
• Set up and maintain tools and fixtures, identify assembly issues, and provide feedback to improve tooling and work instructions.
• Organize materials and document completed work, process results, and observed defects.
• Maintain a clean and safe work area and follow all requirements for soldering equipment, adhesives, power tools, and PPE.
