• Contribute to CI/CD pipelines and improve engineering workflows

• Troubleshoot issues across application and infrastructure layers

• Mentor engineers and contribute to a strong engineering culture

• Work closely with cross-functional teams to deliver production-ready systems

Required

• Strong experience building production systems using C#, TypeScript, or Java

• Solid experience working with cloud platforms (AWS, Azure, or GCP)

• Good understanding of system design and scalable architectures

• Experience building and consuming APIs (REST / event-based systems)

• Comfortable working across the full delivery lifecycle (build, deploy, operate)

• Strong grasp of software engineering fundamentals and best practices

• Ability to take ownership and drive technical solutions

Nice to Have

• Frontend development experience using React, Angular, or Vue

• Experience with infrastructure-as-code (e.g. Terraform, CloudFormation)

• Exposure to containerisation (Docker, Kubernetes)

• Familiarity with CI/CD tooling (GitLab CI, GitHub Actions, etc.)

• Experience working in cross-functional or product-focused teams

• Interest in improving engineering standards, tooling, and ways of working
