The Role

We’re looking for experienced Senior Software Engineers who enjoy building scalable systems, working with cloud infrastructure, and delivering high-quality software in production environments.

This role sits at the intersection of software engineering and cloud/platform work. You’ll be designing and building backend services using technologies like C#, TypeScript, or Java, while working closely with modern cloud platforms.

It’s a strong fit for someone who takes ownership, is comfortable leading on technical decisions, and enjoys improving how systems are designed, built, and operated.

What You’ll Be Doing

  • Design, build, and maintain backend services using C#, TypeScript (Node.js), or Java

  • Develop cloud-native applications across AWS, Azure, or GCP

  • Contribute to system architecture and make key technical decisions

  • Work with distributed systems, APIs, and event-driven architectures

  • Collaborate with platform teams to ensure reliable, scalable deployments

  • 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
