Test Engineer

What You’ll Do

Design and implement test automation frameworks for microservices-based platform components

Build and maintain reusable test libraries and utilities for the L-CAP test infrastructure.

Integrate automated tests into CI/CD pipelines, ensuring continuous quality gates.

Conduct performance testing to validate system behaviour under load and stress conditions

Execute integration testing across platform services, APIs, and external system interfaces.

Develop test plans and strategies aligned with sprint and PI objectives

Analyze defect patterns and test metrics to identify quality trends and improvement opportunities

Collaborate with development and systems engineering teams on testability and quality requirements

Support test environment configuration and test data management activities

Mentor junior test engineers on automation practices and testing methodologies

Design and execute test scenarios based on operational ATC workflows, ensuring modernised services replicate legacy system behaviour

Develop distributed service validation frameworks verifying inter-service communication, data flow, and performance under operational conditions

Implement data-driven verification approaches supporting modernisation of legacy automation functions

Embrace an AI-first engineering culture by actively adopting AI-assisted development tools, automation, and modern engineering practices that improve productivity, code quality, and delivery velocity.
