We are expanding our Systems Engineering and Assurance capability and are recruiting a Junior Systems Assurance Engineer to support the delivery of systems assurance, requirements management, verification and validation activities across major infrastructure projects.

This role is ideal for an engineer with 1–5 years’ experience who is seeking to deepen their expertise in assurance and systems engineering. You will work alongside experienced Systems Engineers and Assurance Leads, gaining exposure to complex, safety‑critical and highly regulated environments.

Firstco is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.

Example Duties and Responsibilities

Applications are open to engineers with experience in systems engineering and/or assurance roles. We are looking for candidates who have experience in some (but not necessarily all) of the following areas:
