Senior Advanced Systems Engineer - 680

We are seeking a Senior Advanced Systems Engineer in our Broomfield, CO, location to lead the delivery of complex infrastructure systems across cryogenic, fluid‑handling, and precision building/facility environments. The ideal candidate brings strong systems integration and field‑execution experience spanning cryogenics, industrial gases, and advanced facility technologies such as precision building controls, environmental systems, and data‑center‑grade mechanical/electrical infrastructure.

All applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test.

Key Responsibilities:

• Own end‑to‑end systems engineering for advanced infrastructure projects, including cryogenic distribution systems, industrial gas systems, and precision facility control systems (e.g., data centers, cleanrooms, high‑stability labs).
• Lead system‑level architecture, requirements definition, trade studies, and requirements flow‑down for cryogenic delivery, facility utilities, and environmental or controls infrastructure.
• Serve as a technical authority for the integration of complex subsystems such as cryogenic equipment, fluid‑handling systems, vacuum‑jacketed lines, compressors, pumps, valves, PLC‑based controls, SCADA/BMS interfaces, and electrical power systems.
• Lead and participate in installation, commissioning, and troubleshooting of equipment and control systems in operational environments—including cryogenic systems, building automation systems (BAS), and precision environmental controls.
• Drive cross‑functional collaboration with mechanical, electrical, controls, facility operations, safety, external vendors, and project teams to resolve interface challenges and deliver reliable integrated systems.
• Support R&D, scale‑up, and continuous‑improvement initiatives by transitioning experimental or prototype concepts into robust, field‑deployable systems.
• Maintain comprehensive documentation, including process workflows, P&IDs, control logic, interface specifications, safety procedures, and operations/maintenance guidance.
  
  

YOU MUST HAVE:

• Bachelor's Degree minimum
• 6 years of experience delivering complex facility or infrastructure systems, preferably involving cryogenics, fluids, or industrial gases.
• 4 years’ experience with design software – ASPEN, EcoSim, AutoCAD, Solidworks, Onshape or similar
• Due to Contractual requirements, must be a U.S. Person defined as, U.S. citizen permanent resident or green card holder, workers granted asylum or refugee status.
• Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.
  
  

WE VALUE:

• Master’s Degree or PHD in Mechanical Engineering, Chemical Engineering, Electrical Engineering, or a closely related field.
• Demonstrated experience with systems integration, commissioning, and field execution
• Strong understanding of cryogenic safety practices, hazard analysis, and operational risk mitigation.
• Experience as an engineering project lead on an infrastructure upgrade or a new pilot-scale project
• In-depth knowledge of safety protocols and regulatory standards related to cryogenic systems.
• Familiarity with systems engineering methodologies (requirements of management, interface control, verification & validation).
• Experience working with vendors, contractors, and external partners on delivered systems.
• Ability to work independently, make technical decisions, and drive issues to closure in fast-moving project environments.
• Strong communication skills and the ability to translate complex technical issues into clear guidance for operations, leadership, and non-technical stakeholders.
