Deep, hands-on AWS expertise - not just familiarity. We’re talking EC2, EKS, Lambda, SQS, S3, RDS, CloudFormation, and beyond
Strong grasp of distributed systems design: event-driven architecture, microservices, fault tolerance, and performance at scale
Experience with Spring Boot and modern Java frameworks
Solid SQL and database design skills (PostgreSQL a plus)

The ability to communicate technical complexity clearly to both engineers and non-engineers

Nice to have:

Experience with Kotlin or Scala
Familiarity with data pipelines, reporting systems, or analytics platforms
Prior experience in a staff or principal IC role

We’re a global product company with a Belfast engineering team that punches well above its weight. You’ll work on problems at a scale most Belfast roles simply don’t offer - and you’ll do it with a team that cares deeply about the craft.
