Compressor Assembly Technician

Come be a part of an exciting clean energy technology startup in beautiful Loveland, CO. You will join an ambitious, talented group decarbonizing the industrial heat sector. AtmosZero is seeking a Compressor Technician to build the precision compressors at the heart of our Boiler 2.0 system. This is hands-on assembly work first. As we scale distribution, the right person will have the opportunity to grow into building and leading a small team of technicians, setting the assembly standards and training the people who follow. We would be excited to find someone interested in that path.

Reports to: Senior Director of Plant Operations

Location: Onsite full time in Loveland, CO (5 days/week)

In this role, you will be responsible for:

• Assemble precision compressor units and subassemblies from aerospace-grade machined parts, working to engineering drawings, tolerances, and specifications.
• Read and interpret engineering drawings, geometric dimensioning and tolerancing (GD&T), schematics, and bills of materials; assemble to torque, fit, and tolerance specs using calibrated hand and power tools.
• Write, refine, and maintain assembly SOPs and work instructions. Work from partial or incomplete inputs and determine what needs to be created versus updated.
• Perform in-process and final quality checks, including leak and pressure testing of assembled units. Record results and maintain build records, inspection sign-offs, and part traceability.
• Support incoming inspection of machined parts and partner with supply chain on supplier quality and nonconforming material.
• Partner directly with design engineers and the R&D team on assembly feedback, design-for-assembly, and first-article builds.
• Maintain a clean, organized workspace with foreign object debris (FOD) control, and follow all safety and PPE protocols.
• Contribute to continuous improvement of assembly processes as production scales.
• Help establish the assembly standards, documentation, and training that a growing technician team will work from.

Required Qualifications

• Demonstrated precision mechanical assembly experience (compressors, pumps, engines, turbomachinery, aerospace, medical device, or comparable high-tolerance work).
• Ability to read and work from engineering drawings, GD&T, schematics, and bills of materials.
• Proficiency assembling to torque, tolerance, and fit specifications with calibrated hand and power tools.
• Experience writing or substantially improving assembly SOPs or work instructions.
• Comfort operating from partial documentation and deciding what to build versus what to update.
• Experience working within a documented quality process (inspection records, part traceability, nonconformance handling) in a high-reliability or regulated environment.
• Strong attention to detail, manual dexterity, and pride in workmanship.
• Clear written and verbal communication to interface with design engineers and technical experts.
• Authorization to work in the U.S.

Technical

• Precision measurement and inspection: calipers, micrometers, bore gauges, dial indicators; measuring runout, concentricity, and clearances to spec.
• Rotating-assembly work: bearing and seal installation, shaft alignment, and rotor balancing or runout verification.
• Mechanical fits and joining: press, shrink, and slip fits; threaded and fastened joints to torque spec; brazing or soldering as applicable.
• Cleanliness and contamination control for close-clearance parts, including FOD prevention.
• Leak, pressure, and vacuum or evacuation procedures, with the test documentation that goes with them.
• Familiarity with rotating equipment or sealed (hermetic / semi-hermetic) compressor assemblies.

Preferred Qualifications

• EPA 608 or other refrigerant handling certification.
• Experience in low-volume or prototype-to-production (NPI) manufacturing environments.
• Experience contributing to design-for-manufacturability or design-for-assembly.
• Lean, 5S, or continuous improvement exposure.
• Trade certification, associate degree, or equivalent demonstrated hands-on experience.
• Basic experience with Solidworks E Drawings/CAD
• Experience training and developing technicians or building out a small assembly team, and interest in growing into that as the function scales.

Physical Requirements

• Stand, bend, reach, and perform detailed hand work for extended periods.
• Lift and carry up to 25 lbs regularly, and up to 40 lbs occasionally with assistance or lifting aids.
• Fine motor dexterity and close-vision work with small components and hand tools.
• Use required PPE and work safely in a shop and light-manufacturing environment.
