Controls Engineer

AtmosZero•Loveland, CO

23d•$125,000 - $180,000•Onsite

About The Position

AtmosZero is hiring a Controls Engineer to help move its Boiler 2.0 modular industrial heat-pump platform from development hardware into repeatable customer delivery. The role focuses on completing controls implementation, integration, testing, and commissioning readiness for a 1 MW customer system, then turning lessons from the first system into reusable controls standards and tools for future systems. The position is hands-on and hardware-close, spanning design documentation, PLC code, HMI and SCADA configuration, panels, field devices, test equipment, and operating data. The engineer will 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. The role reports to the VP, Engineering and is based onsite in Loveland, Colorado.

Requirements

Bachelor's degree in electrical engineering, controls engineering, computer engineering, computer science, mechanical engineering, or a related technical discipline.
At least 5 years of relevant experience developing and commissioning industrial control systems for complex equipment or processes.
Hands-on proficiency with IEC 61131-3 PLC programming, including Structured Text and at least one of Ladder Logic or Function Block Diagram.
Experience with Siemens PLCs and TIA Portal, including integrated hardware configuration, communications, and troubleshooting.
Experience developing industrial HMI or SCADA applications and implementing alarms, trends, historian tags, user access, and operator workflows.
Experience with industrial instrumentation, analog and digital I/O, drives, motor controls, field devices, and networked equipment.
Demonstrated ability to commission and troubleshoot 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.

Nice To Haves

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.

Responsibilities

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.
Resolve controls issues during panel checkout, I/O checkout, build, factory acceptance testing, commissioning, and early operation.
Develop modular, state-based control software using consistent equipment modules, control modules, interfaces, naming, and version-control practices.
Configure Siemens PLCs and distributed I/O hardware, industrial networks, drives, IO-Link devices, instrumentation, and third-party equipment interfaces.
Create reusable code libraries, simulation and test utilities, diagnostic tools, and deployment practices to reduce commissioning effort and replication risk.
Build and maintain operator interfaces for commissioning, local operation, troubleshooting, and service, with clear alarm and abnormal-condition presentation.
Integrate local and centralized data collection, historian functions, trends, event logging, dashboards, and remote monitoring while appropriately separating customer and internal networks.
Use operating and commissioning feedback to improve diagnostics, alarm rationalization, service workflows, and product reliability.
Work with process and thermal engineers to translate theory of operation, P&IDs, operating envelopes, and protection requirements into tested controls behavior.
Work with electrical engineering and panel suppliers on schematics, I/O architecture, device selection, networking, panel checkout, cable and signal issues, and field changes.
Work with manufacturing, test, and field teams to define acceptance criteria, test procedures, troubleshooting methods, and controlled software releases.
Maintain controls design specifications, software descriptions, sequence diagrams, I/O maps, alarm and interlock lists, network architecture, test records, release notes, and troubleshooting guides.
Support DFMEA, design reviews, safety reviews, change control, and root-cause investigations, and drive controls actions to verified closure.
Convert first-unit learning into released standards, templates, work instructions, and commissioning packages for subsequent systems.
