The posting, in Xcimer Energy's own words
archived Oct 29, 2026Responsibilities:
Define and maintain the plant control system architecture: safety, real-time, and supervisory control layers, network segmentation, precision timing and triggering, and plant data capture, documented in architecture descriptions and control narratives. Develop control system requirements and interface definitions between the plant control system and the plant’s major systems, and carry them through gated design reviews and change control. Contribute hands-on controls and instrumentation design within other plant systems: I/O and signal definitions, control sequences, interlocks, and operating modes. Evaluate and select control platforms, protocols, and standards, and build prototype or testbed implementations to retire architecture risk early. Support the program’s control systems director with trade studies, technical analyses, design review material, and staffing and schedule inputs for the control system scope.
Qualifications:
Education: Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related STEM field; an advanced degree is a plus. Experience: Typically 10+ years of relevant experience in control systems engineering for large, multi-subsystem facilities such as power plants, process plants, accelerators, or large laser or research facilities, including ownership of system-level or architecture design. Working knowledge of industrial control architectures: PLC or DCS and safety instrumented systems, SCADA/HMI, industrial networks, and plant historians. Experience developing control requirements, interface control documents, control narratives, and architecture descriptions through formal design reviews. Ability to work independently on complex, loosely defined problems and to communicate architecture decisions clearly to engineers, scientists, and leadership. Willingness to travel 10 to 20% of the time between Xcimer’s Denver headquarters and the program’s future plant site. Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee of granted asylum.

Desired:
Experience with nuclear or other licensed facilities, including safety classification, defense in depth, and instrumentation and control qualification. Experience with functional safety lifecycle work (IEC 61508/61511), SIL allocation, and cause and effect design. Experience with precision timing and triggering, high-speed data acquisition, or pulsed power controls. Experience with OT cybersecurity (IEC 62443) and segregated control network design. Hands-on experience with Beckhoff TwinCAT, Siemens, Rockwell, or EPICS-class control platforms, and with Python or LabVIEW for test automation.
