The Applications Engineer supports the commercial design and quoting process for In-Core Instrumentation (ICI), probes, and sensors used in nuclear reactors. These instruments are critical for monitoring and controlling reactor core conditions—neutron flux, temperature, and pressure—to ensure safe and efficient operation.

This role bridges the gap between engineering and commercial teams, providing technical expertise during the exploratory design phase to ensure proposed solutions align with both customer requirements and manufacturing capabilities.

The Applications

Engineer partners closely with the commercial organization to support major nuclear utilities as well as emerging SMR (Small Modular Reactor) operators, delivering technically sound, cost-effective solutions tailored to each reactor’s needs.

Technical Sales Support: Partner with the commercial team to develop technically sound proposals and quotations, ensuring alignment with both customer requirements and internal manufacturing capabilities. Act as a primary technical interface for customers—participating in design reviews, clarifying specifications, and guiding exploratory design discussions for ICIs, neutron detectors, and related sensor systems.

Review reactor core layouts, sensor placement requirements, and interface specifications to generate conceptual designs, BOMs, and configuration options supporting bid packages. Work closely with design engineering, manufacturing, and quality teams to ensure proposed solutions are feasible, cost-effective, and compliant with nuclear safety and regulatory standards. Prepare technical content for quotes and proposals, including datasheets, preliminary drawings, performance summaries, and design assumptions.

Voice of Customer: Capture field and customer insights to inform design improvements, product standardization, and new development initiatives. Work closely with design engineering, manufacturing, and quality teams to ensure proposed solutions are feasible, cost-effective,



and compliant with nuclear safety and regulatory standards. Support early-stage discussions with next-generation nuclear developers (SMRs, microreactors) to adapt product offerings to new designs and reactor geometries.
