Our view of agile software development is inspired by eXtreme Programming rather than Scrum. We focus more on the technical practices that enable agility, such as TDD, Pair Programming, SOLID, Simple Design etc. but we do find some of the rituals useful, such as Daily Stand-ups and Retrospectives.

  • C#
  • .NET Core (MVC, RESTful Web APIs, dependency injection)
  • SQL Server, Entity Framework
  • HTML, CSS, jQuery

Your skills

  • You will be the sort of person who enjoys getting things done.
  • You will need to be great at thinking logically, but also laterally.
  • You must be able to communicate your thoughts well.
  • You should enjoy collaborating with others and relish solving challenging problems.

Your experience

  • You will have a minimum of five years development experience using C# & .NET in a commercial environment.
  • Experience of enterprise product development would be particulalry relevant to our business.
  • You will be comfortable working in an agile environment. Experience of any eXtreme Programming practices that are key to being agile, such as TDD, Pair Programming, SOLID, Simple Design would also be beneficial.

Working at GMSL

We are a small team. We have around 30 people in our software team, so even though we are a part of a company of around 100 people overall, the software team has retained a small team “startup” feel. Your colleagues will be from a wide variety of backgrounds – we encourage diversity, openness and gender equality.

We value the long-term. The success and stability that comes from 25+ years’ experience in software development means we value the long-term in terms of software development and the development of our people.

We empower teams and individuals. Teams are empowered to own their products. Individuals are empowered to make meaningful contributions at every level.

We are agile. We develop using an agile approach, which focuses on our ability to respond to change. We broadly follow XP practices, but we take a pretty pragmatic view about this. We adapt our processes to support the context, rather than follow a standard rigid process for all situations. We trust the teams who do the work to decide how best to do it.

We strive to make GMSL a great place to work. The management team are friendly, approachable and care personally about the people on their team. Managers consider the people on their team as the first priority and take our people’s personal situations into account in decision-making wherever they can.

We are flexible. Our teams typically work at least one day a week in our office in Cambridge, and the rest of the time working from home. We also have a day a month where the whole software department come in and we all go to the pub for lunch. Hours are flexible and are based on the needs of the team.
