Company mission
To stop bad things from happening to good organisations.
Role
Who you are
- A foundation in programming in at least one language such as Java, C# or Python
- A willingness to use AI coding tools (e.g. Cursor, Claude, or GitHub Copilot) responsibly as part of your daily workflow
- Curiosity about how modern software is built and run — APIs, cloud, containers, and production systems — and eagerness to learn our stack
- A bias for learning by doing, asking questions, and improving with each iteration
- You have a bias for action and prefer shipping small, frequent improvements over big-bang changes
- You are comfortable with production ownership — on-call is part of the job, not someone else's problem
- You participate actively in team ceremonies: refinement, estimation, retrospectives
- You communicate clearly in writing — our teams are distributed, and async clarity matters
- You are comfortable saying "let's do this the right way" even when the shortcut is tempting
- You ask for help when you need it and give it freely when others do
- We're looking for early-career engineers with the drive to learn and the adaptability to thrive. You don't need to tick every box — you need to be ready to grow into them
What the job involves
- As an Associate Software Engineer in the GCI pillar, you will build and maintain full-stack features — from modern, containerized backend services to user-facing React interfaces — that power compliance and insights for enterprise collaboration and email data
- Your primary focus is feature development: working across C# and Java codebases, contributing to the React frontend, and owning your work from design through production
- You will work in a small, focused, cross-functional squad in close partnership with product, and alongside our SRE team who will guide you on deployment, observability, and infrastructure best practices
- Build and maintain backend services in Java and C# (.NET) — including evolving mature C# codebases and contributing to greenfield Java services
- Contribute to React frontend work to complete vertical slices of functionality end to end, carrying features from API to screen when the work requires it
- Write well-tested, observable code that integrates with shared dashboards and our platform's logging and tracing standards
- Build on a modern, cloud-native technology stack — leveraging AWS services (including SQS, S3, and Bedrock), PostgreSQL, Elasticsearch, Kubernetes, and Grafana to deliver scalable, observable, and resilient features
- Handle production incidents as part of an on-call rotation, and feed learnings back into the codebase and runbooks
- Participate actively in sprint refinement and estimation, bringing both technical context and genuine curiosity to the conversation
- Build high-quality, performant, scalable, and testable software — treating quality as a first-class concern from design through delivery
- Partner with SRE — following their guidance on deployment practices, observability standards, and infrastructure conventions to ensure your services are production-ready
- Use AI tooling as a standard part of your daily engineering workflow: for code generation, debugging, documentation, review, and design
