Applications Engineer

Job Details
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.

Description
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.

Core Duties/Responsibilities

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.

Customer Engagement

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.

Design Translation

Review reactor core layouts, sensor placement requirements, and interface specifications to generate conceptual designs, BOMs, and configuration options supporting bid packages.

Engineering Collaboration

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.

Proposal Documentation

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.

SMR & Advanced Reactor Engagement

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

Responsibilities – Safety & Quality

All employees are expected to follow government and corporate laws, rules, regulations, policies, and procedures.

All Cambridge employees play a role in the implementation of the site Quality and Safety Policy, which outlines a safe work environment as the foundation for the business unit’s goal to create a positive customer experience.

Supervisory Responsibilities

No direct supervisory responsibilities, but scope includes indirect responsibility for Mirion Technologies’ supplier quality management processes.

Skill/Knowledge & Other Requirements
Educational

Bachelor’s degree in Mechanical, Electrical, or Nuclear Engineering (or related field). Master’s degree preferred.

Licensed Professional Engineer (PE).

Experience

Minimum 5+ years of engineering experience in the nuclear industry, ideally in core instrumentation, neutron flux sensors, or radiation detection systems.

Prior exposure to in‑core instrumentation or reactor physics applications strongly preferred.

Experience supporting customer proposals, design reviews, or bid development within a regulated technical environment.

Physical

Regularly required to sit, stand, and walk 2-4 hours at a time.

Required ability to use hands and fingers to operate a computer keyboard, mouse, and telephone.

Frequently required to sit and reach with hands and arms.

Verbal and listening skills required.

Must occasionally lift and/or move up to 40 pounds.

Work will be performed in the office and various production site work environments.

Other Requirements

Working knowledge of reactor instrumentation systems for safety and non‑safety applications (flux mapping, radioactive decay, response time, thermocouples, liquid level probes, and EQ requirements).

Ability to interpret reactor drawings, I&C schematics, and mechanical interfaces.

Familiarity with ASME, IEEE, and 10

CFR‑related design standards.

Proficiency in 3D CAD (Solid Works/AutoCAD), Microsoft Office, and engineering documentation.

Excellent communication and presentation skills for interfacing with technical and commercial stakeholders.

Strong analytical and problem‑solving skills with a customer‑first mindset.

Ability to manage multiple concurrent quoting and design support activities under tight timelines.

Working Conditions While Performing The Job

Work will be performed in office and various production site work environments.
