Senior Software Engineer – C# / .NET (Web and Windows) – Near Edinburgh Hybrid – 70K plus Bonus

Lorien’s longstanding client based near Edinburgh is a leader in their industry with a growing and award winning product line that makes a huge difference around the globe. They are looking for a Senior Software Engineer with strong .NET skills across Web and Windows applications. This is a hands on development role focused on C# / .NET, full stack development, user interface delivery, system integration, software quality and continuous improvement.

You’ll work across the full software development lifecycle, from technical requirements analysis and design through to implementation, testing, code review and release. The role suits someone who enjoys solving complex engineering problems, building maintainable software and contributing to robust development practices within an Agile environment.

Key responsibilities

  • Analyse technical requirements and translate them into clear, testable software tasks and specifications
  • Design, implement and maintain new software features, ensuring solutions are scalable, reusable, maintainable and aligned with functional and non functional requirements
  • Define and integrate interfaces between internal and external systems, collaborating with other technical teams to agree robust specifications
  • Contribute to user facing application development, including process flows, information architecture, wireframes and usability focused interface delivery
  • Follow coding standards and ensure code is integrated frequently into automated build and continuous integration processes
  • Write and maintain unit tests, investigate test failures and support automated verification activities where required
  • Debug, troubleshoot and diagnose performance, integration and functional issues across development, test and production environments
  • Review code produced by other engineers, identifying design or implementation issues and helping maintain high software quality
  • Mentor junior engineers and promote best practice in software design, development, testing and maintainability
  • Work closely with product, development, automation and DevOps teams to support high quality software delivery

What they’re looking for

  • Strong commercial record of full stack software development across Web and Windows applications
  • Good understanding of software architecture, object oriented design, maintainable coding practices and software engineering principles
  • Comfort working across UI, application, integration and data layers
  • Ability to analyse requirements, propose technical solutions and communicate clearly with technical and non technical stakeholders
  • Ideally but not necessarily any exposure to any of the following:
    • Python / C/C++ / VB / SQL
    • Unit and component testing for software modules
    • Automated build or CI/CD processes
    • Cloud based deployment/automation/staging/testing
    • Jenkins / GitHub / Jira / similar tooling

In return, you’ll join a supportive organisation well versed in keeping their staff happy, with a generous bonus scheme, a hybrid working model with flexible start/finish times, annual salary reviews and plenty of opportunities to upskill and progress professionally.
