Sensor Assembler and Fabricator in Saint Francis, Minnesota at Temperature Specialists, Inc.

About THIS POSTING

Temperature Specialists, Inc. is a manufacturer of custom, high-accuracy temperature sensors used in industrial and laboratory applications worldwide. We are hiring for two related production assembly roles across our General Assembly and MgO Assembly departments. Both positions involve precision sensor assembly work and share a common set of core skills — we will place the right candidate in the department that best fits their background and our current production needs.

Sensor Assembler

General Assembly Department. Core assembly role focused on resistance welding, hydraulic press operation, and potting compound processes to build finished temperature sensors.

MgO Sensor Fabricator

MgO Assembly Department. Broader fabrication role adding TIG welding, lathe operation, belt sanding, and sandblasting on top of core assembly processes.

No prior experience is required for either role — we provide comprehensive in-house training. A background in manufacturing, assembly, welding, or any hands-on production work is a plus.

CORE RESPONSIBILITIES — BOTH ROLES

• Read and interpret blueprints, work orders, and instruction paperwork to assemble temperature sensor components accurately to specification
• Perform resistance welding under a microscope to join small sensor components, requiring steady hands and sustained attention to detail
• Operate a hydraulic press to assemble and compress sensor components to specified tolerances
• Perform potting compound processes to seal and protect finished sensor assemblies
• Use dimensional measuring equipment to verify part specifications and inspect finished assemblies for quality
• Document production output and log completed work orders to support traceability and scheduling
• Communicate with other departments on assembly schedules and custom sensor requirements

ADDITIONAL RESPONSIBILITIES — MGO SENSOR FABRICATOR

• Perform TIG welding of stainless-steel sensor components, producing clean, consistent welds to specification
• Operate a manual lathe to machine and finish sensor components during the assembly process
• Use a belt sander to grind and finish metal components to required dimensions and surface finish
• Operate sandblasting equipment to surface-treat MgO sensor components and assemblies

WHAT WE'RE LOOKING FOR

• Good fine motor skills and manual dexterity — both roles involve working with small sensor components and precision equipment
• Ability to perform sustained close-focus work under a microscope
• Strong attention to detail and a commitment to consistent, accurate output in a production environment
• Ability to read and follow blueprints, work orders, and written assembly instructions
• Collaborative attitude and comfort working within a team environment
• Prior experience in manufacturing, assembly, welding, or a related hands-on field is preferred but not required — all technical skills are developed through our in-house training program
