Staff Electrical Engineer

Job Title:

Staff Electrical Engineer Location:

Danbury, CT or Mississauga, ON This role is central to that effort. We are looking for a principal electrical and controls engineer who has done this kind of work before, someone who can help architect the path forward, raise the technical bar, and mentor a talented team through a meaningful technology transition.

Hybridization and Load-Following Architecture:

Define the electrical and controls architecture for integrating BESS, supercapacitors, or other fast response assets with our MCFC power plants Develop strategies for dynamic load-following, transient response, and power smoothing, capabilities our current systems were not designed for Support grid-forming, islanding, black-start, and high-availability operating modes suited to data center and mission-critical applications Evaluate and select hybrid topologies, inverter interfaces, and energy management approaches that work within MCFC technology constraints

Controls Architecture and Modernization:

Assess and improve our current PLC-based control architecture across ladder logic, structured text, and function block programs for reliability, maintainability, and scalability Establish controls standards and reusable frameworks that reduce the amount of custom tuning required at each customer site Work with the team to systematically reduce field debugging time through better upfront design, validation, and documentation practices Identify where controls architecture changes are needed to support hybridization, load-following, and higher uptime targets Develop and maintain control philosophies, functional specifications, and system-level architecture documentation Support SCADA and HMI integration across plant, module, EBOP, and grid interface applications Simulation, Modeling and

MIL/SIL/HIL

Help the organization build toward a simulation-first development culture; we understand this is a journey and are looking for someone who can lead it practically Develop or adapt dynamic system models using MATLAB/Simulink, Modelica, Python, or equivalent tools that allow controls logic to be tested before field deployment Lead or support model-in-the-loop (MIL), software-in-the-loop (SIL), and hardware-in-the-loop (HIL) efforts as capability is built out Provide practical guidance on which modeling and simulation investments will have the highest near-term payoff in our product development cycle

Power Electronics and Electrical Equipment:

Apply deep knowledge of power electronics used in distributed generation including inverters, rectifiers, DC-DC converters, UPS systems, and associated protection and switching equipment Lead electrical architecture for

HV/MV/LV

distribution systems including transformers, switchgear, electrical panels, VFDs, grounding, bonding, and auxiliary power systems Specify and oversee conduiting, cable tray, wiring, and electrical balance-of-plant (EBOP) systems from concept through installation Develop and review electrical drawing packages including one-line diagrams, schematics, panel schedules, conduit and cable schedules, grounding plans, and as-built documentation Lead or contribute to protection coordination studies, relay settings, arc-flash analysis, and fault current calculations Apply relevant certification and compliance frameworks including FC-1, UL, CE, NFPA, NEC, and IEEE standards across product and plant designs

EPC and Integrator Coordination:

Support technical interface with EPCs, large-scale systems integrators, and equipment vendors across electrical and controls scope Define contractor deliverables and review EPC-produced drawings, specifications, and submittals for technical accuracy and compliance Support utility interconnection activities including coordination with utilities, EPCs, and permitting authorities Manage technical interfaces across multi-party projects, ensuring alignment between FuelCell Energy's engineering standards and contractor execution Provide technical input during procurement, bid evaluation, and vendor qualification processes

Commissioning and Field Support:

Support FAT, SAT, commissioning, startup, energization, and field troubleshooting activities Develop commissioning plans, LOTO procedures, and customer acceptance protocols Support root cause analysis and corrective actions for controls and electrical field issues Coordinate with field service teams during installation, startup, and system integration at customer sites

Required:

Bachelor's degree in Electrical Engineering or closely related field 8+ or more years of relevant experience in industrial controls, distributed generation, or complex power systems Hands-on PLC programming experience across ladder logic, structured text, and function block, and a clear view of where that approach has limitations Experience with hybrid power systems, BESS integration, or fast-response storage paired with generation assets Deep working knowledge of power electronics including inverters, rectifiers, converters, and associated protection equipment used in distributed generation applications Experience with electrical drawing packages including one-lines, schematics, panel schedules, and conduit and cable schedules Familiarity with certification and compliance frameworks relevant to distributed power equipment: FC-1, UL, CE, NFPA, NEC, and IEEE standards Demonstrated experience working with EPCs and large-scale systems integrators as a technical owner, including drawing review, specification development, and contractor coordination Working knowledge of protection coordination, grounding, arc-flash analysis, and industrial electrical safety Experience supporting field commissioning and startup, with a practical understanding of what it looks like when controls are not right and why Experience with or genuine interest in advancing simulation-based controls development including MIL, SIL, and HIL methodologies Strong communicator, able to explain technical tradeoffs clearly and work across engineering, field, and commercial teams Hands-on experience with

MIL/SIL/HIL

environments or digital twin development using MATLAB/Simulink, Modelica, or equivalent

Preferred:

Experience with fuel cells, electrochemical systems, or other slow-response generation assets that require hybridization for dynamic applications Experience with data center power infrastructure, UPS architectures, or high-availability power design Familiarity with grid-forming inverters, microgrid controllers, or utility-scale energy management systems Experience with DC power systems, high-voltage DC distribution, or insulation monitoring Experience with ETAP, AutoCAD Electrical, EPLAN, SolidWorks Electrical, or similar engineering tools PE license or EIT designation
