- Working across cloud infrastructure (AWS, GCP or Azure)

- Improving performance, reliability and observability of live systems
- Collaborating with product and engineering teams to deliver real impact
- Supporting and mentoring engineers around you
What we're looking for
- Strong commercial experience as a Backend Engineer in Java and/or Go
- Hands‑on experience building and running systems on cloud platforms (AWS, GCP or Azure)
- Solid understanding of microservices and distributed architectures
- Experience with REST APIs and relational or NoSQL databases
- Comfortable in a CI/CD‑driven engineering environment
- A proactive engineer who takes pride in what they build
Nice to have
- Experience with Kubernetes or Docker
- Infrastructure as Code (Terraform or similar)
- Background in security, fintech or high‑throughput systems
This role would suit someone who wants genuine ownership, interesting technical challenges and the chance to grow with a company that's scaling fast.
