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.

Key Responsibilities

• Design, develop, and maintain desktop‑based software supporting data acquisition, processing, and analysis
• Contribute to back‑end logic, data handling, and system integration
• Use Git with established branching and merge strategies
• 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
• Experience building or maintaining desktop applications or system‑focused software
• Exposure to back‑end or data‑driven development
• Comfortable working with structured data, real‑time systems, or computation‑heavy logic
• Practical experience using Git and collaborative development workflows
• Ability to learn new domains and work effectively within a small engineering team
• Clear communicator, able to explain technical concepts to non‑software specialists
• Background or strong interest in geophysics, geology, physics, engineering, or applied science
• Experience with scientific instruments, test equipment, or data acquisition systems
• Exposure to numerical methods, signal processing, or scientific data analysis
• Experience working in multidisciplinary engineering teams (hardware, firmware, R&D)
• Mentoring, knowledge sharing, or willingness to support junior colleagues
• Annual performance‑based bonus
• Company pension contributions
