About the Company

A well-established engineering business based in North Wales is seeking a Software Engineer to join its multidisciplinary engineering team. The company designs, develops, and manufactures specialist instrumentation and analytical technologies used in demanding scientific and technical environments.

This role sits at the core of a complex product stack, delivering desktop-installed software that interfaces directly with highly specialised hardware and data acquisition systems. While modern web technologies are used within the application stack, the primary challenges lie in back‑end logic, data handling, system integration, and reliability.

The Role

You will contribute to the design, development, testing, and maintenance of robust software systems used to control, acquire, process, and present scientific data. The software acts as the primary interface between advanced measurement hardware and its users, requiring dependable real‑time behaviour, clear presentation of complex data, and strong engineering discipline.

This position suits a capable, technically curious engineer, from an early‑career developer through to a mid to senior‑level engineer (Candidates at all levels of seniority will be considered), who is comfortable learning domain‑specific systems and working closely with hardware, firmware, and scientific colleagues.

Maintain build and technical documentation
Write and maintain unit tests for critical code paths
Support CI/CD pipelines where appropriate
Track and resolve issues using tools such as GitHub Issues or Jira
Evaluate and integrate open‑source libraries, ensuring appropriate licensing
Collaborate closely with hardware, firmware, and scientific engineering teams
Contribute ideas and improvements through technical reviews
Ensure all design and documentation complies with ISO 9001 standards

Skills & Experience

Experience with technologies such as Node.js, Express, Vue.js and Electron
Strong programming fundamentals and a solid understanding of software engineering principles
