Pay: Starts at $20.50 per hour with fast growth

Interesting, challenging work with a big impact and room to grow on a team with excellent benefits. If you take pride in doing careful, hands-on work well — and you want that work to actually mean something — keep reading.

Rheo Engineering is a fast-growing team of roughly 100 engineers, craftsmen, and professionals building the powder handling systems and products that help pharmaceutical manufacturers produce medicine safely, efficiently, and reliably. We’re a critical link in the medicine supply chain, and we take that responsibility seriously. Our values — Bold Humility, Reliability, Collaboration, Competence, and Initiative — aren’t just words on a wall. They shape who we are and who we hire.

As an Assembler I on our Rheo Flexibles production team, you’ll build custom powder handling products used to manufacture medicine around the world. You’ll work with specialized equipment in a cleanroom environment, follow detailed procedures, and hold yourself to a standard our customers depend on.

This is a first-shift role: 7:00 AM – 3:30 PM, Monday–Friday.

If you thrive in a structured, hands-on environment and want room to grow, there’s a real path here.

  • Wear required PPE consistently while in applicable work areas

  • Contribute to team production targets — in both throughput and quality

  • What Success Looks Like

  • Your assemblies are completed on time, to spec, and pass inspection without rework

  • Cleanroom protocols and PPE requirements are followed consistently and without exception

  • The team doesn’t have to slow down or compensate for gaps in your execution — they know they can count on you

  • Ability to read and follow blueprints and multi-step written and verbal instructions

  • Detail-oriented — quality is non-negotiable in this environment

  • Dependable — the team knows they can count on you to show up ready and follow through

  • Hands-on aptitude — you take pride in doing precise, physical work well

  • Adaptable — you learn quickly and adjust as products and processes evolve

  • Basic computer proficiency (Windows-based systems, data entry, standard applications)

  • Basic familiarity with ERP software (Epicor Kinetic preferred)

  • Preferred Qualifications

  • Prior experience in a cleanroom or regulated manufacturing environment

  • Familiarity with heat sealing, vacuum forming, or CNC equipment

  • Why Rheo

  • Meaningful work — the products you build help make life-saving medicine around the world

  • A steady schedule you can count on — first shift, Monday through Friday

  • A values-driven team where reliability and craftsmanship get noticed and rewarded
