Read this first: Research shows that while men apply to jobs when they meet an average of 60% of the criteria, women and other marginalized groups tend to only apply when they check every box.

We'd love to have a chat to see what skills/experiences you are able to bring to this team.

What you need to know about the Belfast Tech Scene
If asked to name the birthplace of the RMS Titanic, you might not say Belfast. Similarly, if asked to name Europe's leading destination for foreign direct investment in new software development, Belfast might not come to mind. Yet, both are true. The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
