  • Strong experience in desktop GUI development
  • Experience with RAD Studio (desirable) or Visual Studio
  • Strong analytical and problem-solving skills
  • Experience leading or taking ownership of software projects

  • APIs and inter-process communication
  • Exposure to vacuum systems or laboratory equipment
  • Understanding of compliance requirements for regulated markets
  • BSc (or higher) in Computer Science or related discipline

  • Full-time, permanent
  • 36.5 hours per week

Who This Role Suits

This position is ideal for an experienced C++ desktop engineer who:

  • Enjoys building robust, high-performance software
  • Is confident taking technical ownership and leading projects
  • Wants to work on meaningful scientific applications
  • Values stability, long-term progression and technical depth over short-term churn
