Process Systems Engineer

AtmosZero  ·  Loveland, Colorado (onsite)  ·  Full-time 

Reports to: Sr. Director, New Product Development 

Why this role exists 

Boiler 2.0 is a modular industrial heat pump that produces steam from electricity and air. AtmosZero is running Pilot, Prototype, and 1 MW development activities in parallel, and each system must be tested, understood, protected, and improved. This role adds hands-on process-engineering capacity across those systems so existing technical leaders can focus more heavily on product segmentation and cost-down engineering. 

Level and scope 

• Engineer III. Independently own significant process or thermal-system workstreams, coordinate technical interfaces, and deliver results from requirements and analysis through testing, troubleshooting, and implementation. 
• Senior Engineer I. Lead complex system work through ambiguity, own major technical workstreams end to end, mentor teammates, and influence cross-functional decisions.

What you will do 

• Test, troubleshoot, and improve 
• • Define test objectives, plans, procedures, acceptance criteria, instrumentation, and data-acquisition requirements across Pilot, Prototype, and 1 MW systems. 
  • Support test execution, analyze operating data, identify root causes, and define engineering changes that close performance and reliability gaps. 
  • Prepare systems for commissioning and resolve process, instrumentation, and controls issues during startup and operation. 
• Define how the system operates 
• • Develop operating sequences, operating envelopes, alarms, permissives, interlocks, fault protection, and recovery behavior with controls engineers. 
  • Translate process intent into clear controls requirements, instrumentation specifications, setpoints, and validation tests. 
• Standardize execution 
• • Maintain and improve P&IDs, process requirements, test procedures, operating methods, and decision records. 
  • Convert test and operating learning into repeatable system designs, validated limits, and controlled engineering changes. 

What success looks like in your first year 

• In the first 90 days, build a working model of the Pilot, Prototype, and 1 MW systems and independently support a test campaign or commissioning-readiness workstream. 
• By six months, own recurring test and troubleshooting work, close process or controls issues, and release the resulting procedures or engineering changes. 
• By twelve months, establish a standardized process, operating method, or protection strategy that is validated in hardware and reused across systems. 

What we need from you 

• Bachelor's degree in mechanical engineering, chemical engineering, or a related discipline, with relevant experience at the level at which you are hired. 
• Strong command of thermodynamics, heat transfer, fluid mechanics, and process-control fundamentals. 
• Demonstrated experience testing and troubleshooting thermal-fluid or process systems in hardware. 
• Experience with instrumentation, data acquisition, test planning, data analysis, P&IDs, operating procedures, and engineering-change definition. 
• Ability to develop operating sequences, alarms, permissives, interlocks, and fault-protection requirements with controls engineers. 
• Comfort working directly with technicians and engineers in a startup environment where systems and documentation evolve together. 

What would help 

We do not expect anyone to have all of this. 

• Advanced degree in mechanical engineering, chemical engineering, or a related discipline. 
• Experience with industrial heat pumps, refrigeration, steam systems, process skids, HVAC equipment, or comparable thermal-fluid hardware. 
• Experience with PLC-controlled equipment, controls commissioning, functional testing, or cause-and-effect development. 
• Fluency with MATLAB, Python, EES, Aspen Plus/HYSYS, GT-SUITE, or comparable analysis tools. 
• Experience taking prototype hardware through commissioning, qualification, production release, or field troubleshooting.

• Engineer III [$110,000 - $165,000]
• Senior Engineer I [$125,000-$180,000]
