We are looking for an experienced Senior QA Engineer to lead testing across several of our engineering teams in Belfast. This is a hands-on engineering role: writes test code every week, the person in it builds and maintains test frameworks, and sets the standard for how the teams around them test their own work. Spanning back-end services in Golang and Java and front-end applications in React TS, the teams build distributed scanning systems across all major cloud providers (AWS, GCP, Azure, Oracle), running on Kubernetes, Docker, Neo4j, ElasticSearch, Redis, TimescaleDB, RabbitMQ, and more.

Responsibilities

• Designing, building and maintaining test frameworks and tooling for services, APIs and the user interface, and keeping them fast, reliable and easy for engineers to extend
• Working with teams to create test strategies and deciding what is tested at which level (unit, integration, contract, end-to-end) so that most coverage sits below the user interface
• Integrating automated tests into continuous integration and deployment (CI/CD) pipelines as quality gates, and treating flaky or slow tests as defects to be fixed
• Advocating for testing best practice, and writing the standards, examples and documentation that teams adopt as their default
• Teaching engineers testing concepts, frameworks and techniques through pairing, code review, workshops and written guides
• Reviewing test code and production code with a testing lens, and giving clear, constructive feedback that raises the quality of both
• Working with engineers to make services testable in isolation: interface contracts, test data, ephemer**?** environments and known-correct expected results
• Building test data sets and cloud test environments that let us verify the accuracy of security findings, not only that the code runs
• Contributing to performance, load and reliability testing, and helping teams define measurable quality targets
• Measuring and reporting on quality (escaped defects, test coverage, pipeline stability) and using the results to decide where to invest next
• Interfacing with other teams (e.g. Backend, Frontend, DevOps, Product, Customer Success) to reproduce customer issues, agree acceptance criteria and deliver best-in-class features

We operate on a hybrid working model, with three days per week in our impressive CustomHouse Square offices (Tuesdays, Wednesdays and Thursdays) and the remaining days working remotely.
