Contract Quality Assurance Engineer

Contract Quality Assurance Engineer - 12-Month Contract | Hounslow (50/50 Hybrid) | Up to £380 per day

Every time an aircraft pushes back from the stand, software has already optimised the load, calculated weight and balance, produced a compliant load sheet and absorbed every last-minute change. You could be the engineer who makes sure that software is right, every single time.

This QA role sits within Agile product teams building mission-critical flight management solutions used by airlines worldwide. You'll work closely with Product Managers, Business Analysts, Architects, Engineers, domain experts, and airline customers, validating complex workflows across multiple systems, integrations, and operational domains. If you want your testing to matter - safety, compliance, on-time performance - this is it. You'll also be encouraged to use AI-assisted tooling for test design, automation, defect investigation and documentation.

What You'll Be Doing

Analysing requirements and workflows to define test approaches, and producing test plans, test cases, automation assets and quality reports
Designing, implementing and maintaining automated tests that lift regression coverage and delivery efficiency
Executing functional, integration, end-to-end, regression and exploratory testing
Validating workflows, integrations, APIs and data flows across interconnected products and services
Supporting CI/CD through automated testing and quality validation
Investigating defects, carrying out root cause analysis and driving issues to resolution
Collaborating across product, engineering and domain teams to ensure solutions are testable
Championing improvements in quality, automation maturity and engineering practice, including AI-assisted toolsWhat You'll Bring

A degree in Computer Science, Engineering, Information Systems or a related field
3+ years in QA, Software Testing or Quality Engineering within Agile product development
Proven experience building and maintaining automated testing for enterprise software, integrated into CI/CD pipelines
Solid understanding of APIs, integrations, data models, and distributed applications, with experience of complex, interconnected systems
Self-sufficiency to manage competing priorities in a fast-paced, multicultural environment
Confidence using AI-assisted tools across test design, automation, and defect investigation (AI-Driven SDLC awareness a plus)
