Purpose of the job

As a Senior Software Engineer, you’ll be a key figure in one of our cross-functional teams, designing

and building cloud-native, greenfield products from the ground up. You’ll take ownership of features

and new capabilities, working closely with a Product Manager, Engineering Manager, and your

teammates to deliver high-quality software that is reliable, scalable, and secure.

You’ll be hands-on every day; refining stories, writing code, reviewing pull requests, and solving

interesting technical problems. You’ll bring strong engineering practices to the team and help shape

the way we build software. While you’re not expected to manage people, your technical depth and

experience mean you’ll naturally become a point of reference for others on the team.

We have a modern TypeScript stack, cloud-native environment, containerised deployments, and a

strong focus on automation, observability, and AI-enhanced development.

If you enjoy solving complex problems, delivering high-impact features, and being part of a high-trust,

high-autonomy engineering culture, we'd love to have you onboard.

Key Responsibilities

• Write clean, efficient, and testable code, owning complex features and services from design

to deployment.

• Work closely with your squad (PMs, engineers, QAs) to refine requirements, scope technical

solutions, and deliver great software.

• Champion automated testing and CI/CD. You’ll write unit, integration, and contract tests, and

help make our systems robust and reliable.

• Build, deploy, and monitor services in AWS using tools like Terraform, Kubernetes, and

GitHub Actions.

• Take responsibility for the health, performance, and maintainability of the code you ship.

• Help evolve our engineering standards and practices by sharing knowledge, reviewing code,

and learning from incidents.

• Being a mentor and teacher to less experienced engineers.

Non-negotiable

• 5+ years of experience in software development with a strong focus on TypeScript (Node.js &

React) and excellent knowledge of JavaScript fundamentals.

• Experience building and running production systems in AWS using tools like EKS, Lambda,

RDS.

• Skilled in designing and building GraphQL and RESTful APIs, with practical knowledge of

MongoDB, PostgreSQL, and Kafka.

• Comfortable developing software within an event-driven architecture.

• Deep knowledge of writing automated tests with Jest, Pact, and the principles of TDD.

• Comfortable building and maintaining CI/CD pipelines (we use GitHub Actions) for code

deployment primarily using Terraform.

• Experience using DataDog (or similar) to monitor services and debug production issues.

• Experience working in Agile environments using tools like Git, Jira, and Confluence, with a

mindset of collaboration and continuous improvement.

• Able to take a problem and run with it, bringing a pragmatic, product-focused approach to

software delivery
