Senior Software Developer

We’re seeking an experienced Senior Software Developer to join our team in building complex custom solutions for our varied range of clients. Working within a full end-to-end team, we guarantee you the opportunity to develop your career and work on projects that are diverse, enjoyable and rewarding.

About GCD

GCD was founded in 1999 by our two founders in their student accommodation in Queen’s University, Belfast. It was a time of dial up internet, Netscape browsers and Napster. People didn’t ‘google’ things, smartphones didn’t exist and business software was grey and dreary.

Our ambition back then was (and still is) to create better software for businesses; to replace those ‘grey’ out of the box digital solutions, that barely work and are a pain to use, with beautifully designed custom software products and platforms that help businesses innovate, compete and win.

How we work

Behind our software solutions is a close-knit team of dedicated, ambitious engineers, thinkers and inventors. We love what we do – imagining, designing and building custom software solutions and apps that defy expectations and deliver results for our clients. 

We encourage a full-stack development environment to keep everyone on the same page and always thinking about security, performance and user experience. Typically, we will work on projects in TypeScript, JavaScript, React and PHP, to name but a few.

Everyone at GCD has been working remotely for the past year, in response to the Covid-19 pandemic, and we very much miss seeing each other in ‘real life’. We are genuinely looking forward to the day that we can have in-person chats and work together again at the office. Our plans however are to continue to embrace and offer a flexible approach to working, affording our staff the choice to work from where they feel they will be most productive, whether that’s at home, in the office or a blend of both.
