Precision Resistor Fabricator in Saint Francis, Minnesota at Temperature Specialists, Inc.

About the role

Temperature Specialists, Inc. is a manufacturer of custom, high-accuracy wire-wound RTD temperature sensors used in industrial and laboratory applications worldwide. We are hiring a Precision Resistor Fabricator to join our specialized winding department — performing the second and most exacting phase of our sensor manufacturing process.

In this precision manufacturing and production operator role, you will bond, verify, and finish the wire-wound resistor elements at the heart of every RTD temperature sensor we produce. This is highly detail-oriented, microscope-based work requiring exceptional hand steadiness — you will use a micro acetylene torch to bond wires finer than a human hair and a resistance comparator to verify each element meets specification. No prior experience in resistor fabrication or sensor manufacturing is required — we provide comprehensive in-house training. A background in manufacturing, assembly, electronics, or production work is a plus.

What you'll do

• Operate a micro acetylene torch under a microscope to precisely bond wires smaller than a human hair onto wire-wound ceramic sensor elements — this is among the most delicate production operations in our manufacturing process
• Use a resistance comparator to verify the resistance accuracy of finished RTD temperature sensor elements against specification, ensuring every sensor meets required performance standards before moving downstream
• Perform the high-temperature glassing process using an industrial furnace to coat and seal ceramic tube sensor elements
• Read and interpret blueprints and work orders; use dimensional measuring equipment to inspect finished elements for quality and accuracy
• Document resistance verification results and log completed work orders to support traceability and scheduling across the manufacturing process
• Work collaboratively within the winding department team to meet daily production targets; communicate with downstream assembly on schedules and custom sensor requirements
• Support training of new team members as needed; perform routine maintenance and cleaning of department equipment

What we're looking for

• Exceptional fine motor skills and manual dexterity — you'll be working with components smaller than a human hair using a micro torch and precision instruments
• Ability to perform sustained close-focus work under a microscope for extended periods, with a steady hand throughout
• High attention to detail and a consistent commitment to accuracy and quality in a precision manufacturing environment
• Ability to read and follow blueprints, work prints, and written/verbal instructions accurately
• Collaborative attitude and comfort working within a small, close-knit team
• Prior experience in manufacturing, production assembly, electronics assembly, or laboratory work is preferred but not required — all technical skills specific to this role are developed through our in-house training program

A note on the work

This role involves a brief natural orientation period — the torch bonding work under a microscope is a learned skill that takes time to develop. Candidates who thrive here tend to be patient, methodical, and take genuine satisfaction in producing precise, consistent work. If you've ever enjoyed detailed hand work — whether in assembly, electronics, crafts, or similar — this role is likely a strong fit.

Why join Temperature Specialists

• Work with a specialized, skilled team manufacturing precision products used across diverse industries
• Comprehensive in-house training — no prior resistor fabrication or sensor experience required
• Stable, full-time position with a manufacturer of highly specialized, custom-engineered products
• Opportunity to develop rare, in-demand skills in precision micro bonding and resistor element fabrication
