Senior Software Engineer (Full Stake & DevOps)

Experience in both full stack development and DevOps or platform engineering. This role needs someone who has genuinely done both.

Strong experience in software engineering (typically 5+ years), across both front-end and back-end development.

Proficiency in at least one modern programming language (e.g. C#, Java, Go, or similar), plus experience building web applications, APIs and service-based architectures.

Hands-on ownership of CI/CD pipelines (e.g. Jenkins, TeamCity, GitHub Actions, Azure DevOps) rather than experience of using pipelines someone else built.

Strong working knowledge of cloud architecture — designing for scalability, resilience, security and cost on a major platform such as AWS, Azure or GCP.

Experience with Infrastructure as Code (e.g. Terraform, CloudFormation, Pulumi) to provision and maintain environments repeatably.

Knowledge of containerisation and modern deployment tooling (e.g. Docker, container orchestration).

A considered view on testing: what to test, at which level, and where the return on effort actually is.

Solid understanding of relational databases, version control (Git) and modern development workflows.

Comfortable using AI tools to support and accelerate your work — code assistants, AI-powered IDEs (e.g. Claude Code, Antigravity) or agent-based development workflows.

Strong stakeholder communication, and the confidence to take ownership and challenge existing thinking.

Experience with high-traffic e-commerce systems is beneficial, but not essential.

Real ownership of how software gets built, tested and released — not just what gets built.

High-traffic, commercially critical platforms where your work is visible in the numbers.

A culture that values curiosity, experimentation and continuous learning.

Flexible, hybrid working and a small, capable team.
