Job Description

We are seeking a skilled Software Developer to play a key role in supporting Instrumentation & Control (I&C) system commissioning across a major nuclear project. This role focuses on designing, developing, testing, and supporting software solutions that enable safe, efficient, and compliant commissioning activities on one of the UK’s most significant infrastructure projects.

You will develop robust, scalable applications using technologies such as Python, JavaScript, and PostgreSQL, contributing across the full software development lifecycle – from requirements capture and technical design through to implementation, testing, deployment, and ongoing optimisation.

We are looking for someone who is comfortable working across both server-side and client-side technologies, has a strong understanding of modern web architectures, and takes pride in delivering clean, maintainable, and high‑quality code. A proactive approach to troubleshooting, performance optimisation, and continuous improvement is essential, along with a desire to stay current with emerging technologies and best practices.

This is a hands-on role within a fast‑paced commissioning environment, requiring strong attention to detail, adaptability, and effective collaboration with multidisciplinary teams. Your work will directly support the safe startup and long-term performance of critical nuclear systems.

Roles & Responsibilities:

Design technical solutions to support I&C commissioning engineers, simplifying the use and interpretation of I&C data.
Improve and maintain web-based applications.
Implement backend logic, data processing workflows, and automation solutions using Python.
Build responsive, user-friendly frontend components and interactive features using JavaScript.
Design, manage, and optimise relational databases in PostgreSQL.
Write performant SQL queries, stored procedures, and data migration scripts.
Ensure data integrity and security across environments.
Ensure software quality by testing and writing documentation.
Conduct unit testing, integration testing, and assist in user acceptance testing.
Write technical specifications and installation procedures.
Assist in writing user manuals.
Debug, troubleshoot, and resolve software defects across the stack.
Deploy and maintain these tools.
Collaborate with cybersecurity team.
Ensuring high standards of security, performance, and scalability across all developed solutions.
Contribute to the continuous improvement of development practices and code quality standards.

Fluent in spoken and written English.

Desirable

Degree in software development.
Experience with containerisation technologies such as Docker.
Familiarity with cloud platforms (AWS, Azure, GCP) or on-premises hosting environments.
