About the Role
We are looking for a Senior Software Development Engineer in Test (SDET) who approaches quality as an engineering discipline.
This role goes beyond writing automated tests; you will design and build systems that enable scalable, reliable testing, including tools, frameworks, and supporting services that improve how teams validate software.
You will work across multiple layers of the engineering ecosystem, helping teams validate APIs, services, data flows, and user journeys, while building the supporting tooling that makes testing faster, more reliable, and more insightful.
This role is well suited to engineers who enjoy building internal platforms, automation utilities, test harnesses, data tooling, and diagnostic systems, and who are building/leveraging approaches such as AI-assisted testing and intelligent quality tooling.
Key Responsibilities
Engineering for Quality
Design and build engineering solutions that support quality at scale, including:
Test harnesses for validating services and distributed systems
Stubs and mocks for isolating dependencies
Simulation frameworks for testing complex workflows
Internal tooling that enables developers to validate their systems earlier
Develop reusable components that allow teams to test services and integrations without relying on full environments.
Test Infrastructure & Tooling
Build and maintain the technical infrastructure that enables effective testing, including:
Automation frameworks for UI, API, and integration testing
Test data generation and environment validation tools
Diagnostics and debugging utilities
Execution orchestration tools for CI/CD environments
Develop internal libraries, utilities, and services that improve the reliability and speed of automated validation.
AI-Driven Quality Engineering
Deisng and implement AI-assisted approaches to improving quality engineering, such as:
AI-assisted test generation
automated defect analysis
intelligent test maintenance
anomaly detection in test results
Contribute to the development of internal AI-enabled tooling that improves testing efficiency and insight
Observability & Quality Insights
Design and build reporting and analytics capabilities that provide insight into system quality, including:
Test execution reporting dashboards
Quality metrics and trend analysis
Integration with observability platforms
Defect and reliability analysis tooling
Leverage data to provide actionable insights into product stability, coverage, and risk.
System-Level Validation
Work across the full system stack to validate behaviour including:
APIs and service interactions
Distributed systems and microservices
Data pipelines and persistence layers
Integration points between internal and external services
Investigate failures by analysing logs, metrics, traces, and system behaviour, identifying root causes rather than simply reporting defects.
CI/CD & Engineering Integration
Embed automated validation into development workflows by integrating testing into:
CI/CD pipelines
Pull request validation
environment readiness checks
deployment verification processes
Collaborate with platform and DevOps teams to ensure quality checks are automated, scalable, and reliable.
Required Skills & Experience
Software Engineering
Strong development experience in one or more programming languages, such as:
Java
Python
JavaScript / TypeScript
C#
Experience designing maintainable, production-quality code used for automation, tooling, or internal engineering platforms.
Test Engineering
Experience building automated validation across:
APIs and service layers
integration workflows
user interfaces (where appropriate)
Experience with modern automation frameworks such as:
Playwright
Selenium / WebDriverIO
Cypress
Pytest / JUnit / NUnit
Engineering Tooling & Test Infrastructure
Experience building or maintaining engineering tools such as:
test harnesses
mock or stub services
simulation tools
test data generators
environment validation utilities
Ability to design solutions that enable developers to test systems more effectively.
CI/CD & Platform Integration
Experience integrating automated testing into pipelines such as:
Azure DevOps
GitHub Actions
Jenkins
Familiarity with modern engineering environments including:
Git-based development workflows
containerised environments (Docker)
cloud platforms and distributed systems
Data & Diagnostics
Experience working with databases such as:
PostgreSQL
MySQL
MongoDB
Ability to investigate issues using logs, queries, and system diagnostics.
Nice to Have
Experience with:
Performance testing tools (k6, JMeter, Locust)
Observability platforms (Grafana, Prometheus, ELK)
Container orchestration platforms such as Kubernetes
Distributed system testing
AI-assisted development or AI-enabled testing approaches
What We Value
We are looking for engineers who:
Enjoy building tools and systems, not just writing tests
Think about quality at a system and architecture level
Are comfortable debugging across services, infrastructure, and data
Take ownership of improving engineering practices
Continuously look for ways to increase reliability and developer productivity
By fostering a workplace that is inclusive and welcoming, we aim to harness the full potential of our diverse team. We encourage candidates of all backgrounds to apply, as we believe that a variety of perspectives leads to better decision-making and more effective problem-solving.
