About the Role

As a Senior Cloud & Backend Engineer, you will take ownership of improving and scaling a cloud-agnostic AWS platform while contributing to the development of backend services and new product functionality.

Your primary focus will be strengthening infrastructure, Infrastructure as Code, CI/CD pipelines, software supply-chain security, monitoring and alerting. You will also develop backend capabilities supporting access control, metrics ingestion and multi-tenancy.

Working closely with a small engineering team, you will contribute to platform maturity, product development and long-term technical improvements. This role requires an independent engineer who can take ownership, challenge technical decisions constructively and deliver reliable solutions. Frontend development experience would be beneficial but is not essential.

• Strong practical experience with AWS infrastructure and core services, including EC2, ECS, RDS/Aurora, DynamoDB and Lambda.
• 3 years of experience with Java-based backend services, or relevant backend development expertise applicable to Java microservices.
• Strong hands-on experience with Terraform and Infrastructure as Code (IaC).
• Proven experience designing, maintaining and improving CI/CD pipelines, ideally using GitHub Actions. Equivalent experience with GitLab CI/CD or Jenkins is acceptable where transferable expertise can be demonstrated.
• Knowledge and practical experience of software supply-chain security, including SBOMs, signed container images and image verification.
• Experience implementing and maintaining cloud monitoring and alerting solutions.
• Hands-on experience with Docker, containerised services and container orchestration using ECS and/or Kubernetes.
• Strong backend development experience, with the ability to independently implement new features and functionality in microservices.
• Ability to develop backend functionality involving access control, metrics ingestion and multi-tenancy.
• Experience troubleshooting production infrastructure, deployment pipelines and backend services.
• Understanding of platform reliability, maintainability, security and continuous improvement.
• Ability to work independently, take ownership of technical decisions and contribute beyond assigned development tasks.
• Strong collaboration, knowledge-sharing and problem-solving skills.
• Ability to propose and justify technical improvements constructively.
