Senior Software Engineer
Belfast
A growing Belfast team. A major platform programme. Real influence over what gets built.
Over the past year, I've successfully partnered with this business on multiple hires, helping build its Belfast team to 18 people. Now, as an exclusive recruitment partner, I'm supporting its next phase of growth with opportunities for Senior Software Engineers.
The Belfast team will play a central role in a substantial technology programme, taking ownership of complex integrations and helping shape the platform's future.
What you'll get stuck into
Building full-stack applications, with a strong focus on backend engineering.
Connecting modern software with large-scale enterprise systems.
Shaping architecture and technical decisions alongside experienced engineers.
Working closely with product colleagues in Belfast and engineering teams in the US.
Using AI coding assistants throughout development, testing and delivery.
What you'll bring
You'll have six or more years of software engineering experience, strong technical fundamentals and an interest in solving complex integration challenges.
The core stack is React, Ruby and AWS, but there's flexibility for engineers coming from other backend languages or modern frontend frameworks. Your ability to learn, make sound engineering decisions and deliver reliable software matters.
Full-stack capability with a backend leaning would suit the work particularly well, and practical experience using AI coding assistants is essential.
What's on offer?
35-hour working week, with flexible start and finish times.
An enhanced benefits package being finalised, expected to include a competitive pension, private medical, dental and optical cover, death-in-service cover and a bonus of up to 10%.
Significant ownership within an established and growing Belfast team.
Having helped multiple engineers join this business, I can give you insight into the team, the opportunity and the interview process.
