Controls Engineer

The posting, as Atmoszero wrote it

AtmosZero is building the next generation of industrial steam infrastructure. Our flagship product, Boiler 2.0, is a modular industrial steam heat pump designed to help manufacturers reduce operational risk, improve flexibility, and modernize steam generation over time. Rather than forcing facilities to choose between reliability and sustainability, AtmosZero enables a practical path toward future-ready steam systems that integrate with existing operations and scale with customer needs.

AtmosZero · Loveland, Colorado (onsite) · Full-time · Senior Engineer I
Reports to: VP, Engineering
Why this role exists
Industrial steam runs manufacturing across food, pharmaceuticals, specialty chemicals, and other essential industries, yet most steam is still produced by combustion-based boilers. AtmosZero is replacing that legacy equipment with an electrified platform designed for practical deployment in existing boiler rooms.
Boiler 2.0 is a modular industrial heat-pump system that produces steam using electricity. We are moving the platform from development hardware into repeatable customer delivery, with a 1 MW customer system now driving controls implementation, integration, testing, and commissioning readiness.
The controls challenge spans process sequences, compressor and drive interfaces, distributed instrumentation, protection logic, HMI and SCADA, industrial networking, data infrastructure, and live-system troubleshooting. This role adds the hands-on capacity to complete the 1 MW system and turn first-unit learning into a reusable controls platform for future systems.
Level and scope
We are hiring an experienced engineer who can own major portions of an industrial controls system from requirements through commissioning. The role is intentionally hardware-close: you will move between design documentation, PLC code, HMI and SCADA configuration, panels, field devices, test equipment, and operating data.

• Controls Engineer (5+ years). You own controls implementation and issue resolution for assigned systems and subsystems, while helping establish the architecture, software standards, diagnostics, and commissioning methods needed for repeatable product delivery.

If your experience does not follow a conventional path but you have commissioned complex industrial equipment and can demonstrate strong controls judgment, apply anyway.
What you will do

• Deliver the 1 MW controls system
• Complete PLC programming, sequence implementation, controls integration, and system-level testing for the 1 MW Boiler 2.0 platform.
• Develop and verify startup, normal operation, shutdown, maintenance, fault, trip, and recovery behavior, including interlocks, permissives, alarms, timeouts, and protective responses.
• Own controls issue resolution during panel checkout, I/O checkout, build, factory acceptance testing, commissioning, and early operation.
• Build the controls architecture and software platform
• Develop modular, state-based control software

ot live industrial hardware using drawings, P&IDs, software diagnostics, test instruments, and operating data.

• Ability to produce clear, controlled engineering documentation and communicate effectively across mechanical, process, electrical, software, manufacturing, and field teams.
• Comfort with the ambiguity and pace of a startup building physical hardware, where design, build, and test may occur in parallel.

What would help
We do not expect anyone to have all of this. The first three are the ones we would most like to see.

• Experience with Ignition, including edge or local gateways, centralized gateways, historian configuration, dashboards, and remote-support use cases.
• Experience with Siemens S7-1500-series controllers, WinCC, Weidmuller UR20 I/O, IFM IO-Link devices, Modbus TCP, Profinet, OPC UA, and industrial Ethernet.
• Experience applying ISA-88 concepts to modular, state-based machine or process control and ISA-101 principles to HMI design.
• Experience with refrigeration, heat pumps, boilers, steam systems, turbomachinery, process equipment, or comparable thermal-fluid systems.
• Experience with functional protection logic, alarm rationalization, machinery safety, and standards such as NFPA 79, NFPA 70, UL, or CE requirements.
• Experience with control-panel design review, wiring diagrams, loop diagrams, network diagrams, panel checkout, FAT, SAT, and field commissioning.
• Experience with software version control, coding standards, simulation, automated or bench testing, release management, and change control for industrial controls.
• Experience supporting production equipment, remote fleets, customer sites, or field-service organizations.
• Experience moving a controls platform from prototype development into repeatable production.
