We're always looking for competent web developers who value well-structured code, creative problem-solving, and getting things done without unnecessary faff. You'll work on interesting projects, with a team of developers who know their stuff, in an environment that lets you focus on what you do best. If that sounds like your kind of developer job, we'd love to hear from you. Who are we? We are Gecko, a digital agency based in Edinburgh, but we work with clients across the UK. We specialise in Umbraco websites. We've been in the game for 22 years, creating beautifully designed, highly functional, and refreshingly responsive digital experiences. Our team of developers is small but mighty. We like to move fast, think creatively, and always deliver top-notch work. Through a mix of careful planning, great communication, and genuinely brilliant project management, we've built a team that sticks around - and clients that do the same. Our clients stay with us because we're straight-talking, honest, and ridiculously good at what we do. What will you be doing? * Developing and maintaining Umbraco-powered websites with .NET (C#). * Writing clean, scalable, and maintainable code that plays nicely with our front-end web developer team. * Working with SQL Server, Azure, and modern dev tools to keep everything running smoothly. * Collaborating with designers, project managers, and clients to bring ideas to life. * Troubleshooting, debugging, and generally being a tech wizard. * Keeping up with best practices, emerging tech, and Umbraco updates. While our team of developers is collaborative, we're looking for someone who can pick up a project from start to finish and work independently with strong problem-solving skills. Of course, "independent" doesn't mean "alone" - our Technical Lead is always on hand to provide support. We also use Slack for quick questions and chatting with our colleagues in Chester, Bristol and Portugal. Our work varies between creating new websites and updating existing ones. Some projects are quick turnarounds; others take months. As a Full Stack Web Developer, you'll integrate third-party services and support clients long after the big jobs are done. You'll work on diverse development projects, using your development skills across web and mobile development. Every week brings something new, so we're looking for someone with a genuine enthusiasm for web application development and the development of software - from writing clean code to exploring the latest industry trends. What You'll Need to Succeed Experience & Qualifications * Minimum of 3 years' web development experience. * An experienced software developer, ideally with a degree in Software Engineering, Computer Science, or a related subject. * Experience in developing and extending Umbraco CMS with a strong understanding of its capabilities. Best Practices & Tools * Knowledgeable in OOP design patterns, best practices, and key principles (SOLID, DRY, etc.). * Experience using industry best practices. * Experience with version control systems such as GIT. Project & Communication Skills * Ability to assist with gathering requirements and creating timescales. * Strong communication skills, with the ability to discuss user requirements clearly. * Experience using XML, XSLT, XPATH, etc. * Participate in regular code reviews and contribute to improving the development workflow.
