Purpose of the job

Senior Software Engineer role: you’ll be a key figure in a cross-functional team, designing and building cloud-native, greenfield products from the ground up. You’ll own features and new capabilities, working with a Product Manager, Engineering Manager, and teammates to deliver high-quality, reliable, scalable, and secure software.

You’ll be hands-on daily—refining stories, writing code, reviewing pull requests, and solving technical problems. You’ll promote strong engineering practices and help shape how we build software. While not required to manage people, you’ll be a technical reference for others on the team.

We operate with a modern TypeScript stack, cloud-native environment, containerised deployments, and a focus on automation, observability, and AI-enhanced development. If you enjoy solving complex problems and delivering high-impact features in a high-trust, high-autonomy engineering culture, we’d love to have you onboard.

Key responsibilities

• Write clean, efficient, and testable code (frontend and backend), owning complex features from design to deployment.
• Collaborate with your squad (PMs, engineers, QAs) to refine requirements, scope solutions, and deliver software.
• Champion automated testing and CI/CD; write unit, integration, and contract tests to build robust systems.
• Build, deploy, and monitor services in AWS using Terraform, Kubernetes, and GitHub Actions.
• Ensure health, performance, and maintainability of the code you ship.
• Help evolve engineering standards and practices by sharing knowledge, reviewing code, and learning from incidents.
• Champion observability using DataDog to monitor services and troubleshoot production issues.
• Identify opportunities to improve development workflows with AI-powered tooling and automation.
• Mentor and support less-experienced engineers.
• Develop in an Agile environment using Git, Jira, and Confluence, with a collaborative, continuous-improvement mindset.

Qualifications

• Preferred: Computer Science or Information Technology degree, diploma, or similar.
• Non-negotiable: 5+ years of software development experience with a strong focus on TypeScript (Node.js & React) and solid JavaScript fundamentals.
• Experience building and running production systems on a cloud platform (AWS and Azure).
• Comfort developing software within an event-driven architecture.
• Experience with technical design and solution architecture.
• Deep knowledge of automated testing and the principles of TDD.
• Experience building and maintaining CI/CD pipelines (GitHub Actions) for code deployment, primarily using Terraform.
• Ability to take a problem and drive it to resolution with a pragmatic, product-focused approach.

Personal attributes

• Show initiative: self-driven, independent problem-solver who takes ownership end-to-end.
• Innately curious: continuously questions, learns, and seeks deeper understanding.
• Innovative: think creatively and implement ideas that enhance our systems.
• Communicative collaborator: share openly, work across teams, and incorporate feedback.
• Strong analytical and investigative problem-solving skills.
• Hungry to make a difference at a technical and operational level.
• Ability to deliver without micro-management; focus on doing the right thing and taking ownership of code.
• Proud of your code and owning your work.
