Process Systems Engineer

About the role

• 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.

Base salary range

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