As a Junior Systems Design Engineer – Nuclear, you will play a key role in the design and delivery of complex, high-reliability engineered systems supporting advanced nuclear and regulated industrial applications. Working as part of a multidisciplinary project team, you will help translate customer and regulatory requirements into robust system designs, gaining hands‑on exposure to the full system lifecycle—from early concept development through detailed design, integration, testing, and commissioning.

This role offers the opportunity to develop a deep understanding of customer processes and technology while contributing to solutions where safety, quality, and performance are critical.

This position is well suited for an early‑career engineer who is eager to grow technical depth and systems thinking capability in a highly collaborative environment. You will be supported by experienced engineers while progressively building ownership of system requirements, technical risk mitigation, and verification activities. Through direct involvement in design reviews, analysis, proof‑of‑principle testing, and on‑site support, you will develop into a trusted technical contributor and subject matter expert, helping deliver innovative, compliant, and reliable systems that make a real‑world impact.

• Assist in the development, documentation, and maintenance of system-level requirements, including functional, technical, and regulatory requirements.
• Support requirements flow-down to subsystems, components, and third‑party equipment under the guidance of senior engineers.
• Participate in requirements verification planning and execution, including analysis, testing, and inspection activities.
• Assist with the preparation and execution of acceptance testing activities such as proof‑of‑principle testing, factory acceptance testing, and site acceptance testing.
• Evaluate design outputs (drawings, calculations, specifications, and test results) for conformance to defined requirements.
• Support the preparation of technical documentation such as verification matrices, test plans, and acceptance test reports.
• Assist in the identification and mitigation of technical risks through structured problem‑solving and design validation activities.

• Learn and develop an understanding of customer processes, system functionality, and applicable nuclear and industrial standards.
• Support system-level and component‑level analysis and calculations, such as functional capability, accuracy, structural considerations, pressure/flow, heat transfer, and reliability, as applicable.
• Assist in the preparation of technical studies, calculations, and design assessments to support system performance and compliance.
• Support the development of risk assessments, including Failure Modes and Effects Analyses (FMEAs) and Safety Risk Assessments.
• Assist with proof‑of‑principle studies and hands‑on testing to validate design…
