Up to £420 p/d Umbrella Rate - Inside IR35

Do you enjoy turning messy operational problems into requirements an engineering team can build? This Technical Business Analyst contract sits in a team creating airline operations software, the systems that help airlines load aircraft, calculate weight and balance and get every flight away safely and on time.

You'll work in Agile product teams alongside Product Managers, Architects, UX Designers, Engineers and airline customers, with a real say in how a complex set of connected products behaves. The role is properly technical: you'll read OpenAPI specifications, query databases and contribute to solution design, using Jira, Confluence and GitHub. It's a 12 month contract, hybrid with half your time on site in Hounslow, and AI-assisted tools are part of everyday analysis.

What You'll Be Doing

• Refining business requirements and customer workflows into user stories, business rules, process flows, acceptance criteria and functional specifications
• Analysing APIs, integrations, data flows and system interactions across interconnected products, reading Swagger and OpenAPI specifications
• Writing and running database queries to investigate data, validate behaviour and support analysis
• Contributing to solution design alongside Architects and Engineers
• Validating requirements and solution designs with Product Managers, Architects, UX Designers, Engineers, domain experts and customers
• Supporting backlog refinement, design reviews, functional validation, testing and release readiness
• Investigating product issues, carrying out root cause analysis and recommending improvements
• Producing clear specifications, process models, data mappings and decision records

What You'll Bring

• A degree in Computer Science, Engineering, Information Systems or a related field
• 3+ years in Technical Business Analysis, Business Analysis, Systems Analysis or Product Definition within Agile teams
• Experience defining functional and technical requirements for enterprise software, with a solid grasp of APIs, integrations and data models
• Hands-on technical skills: reading Swagger or OpenAPI specifications and writing SQL queries against databases
• Experience working in Jira, Confluence and GitHub
• Strong analytical skills and the ability to explain complex operational scenarios to technical and non-technical stakeholders
• Experience using AI-assisted tools for analysis, documentation or solution design

Desirable: airline or airport operations (flight operations, weight and balance, load control, baggage or ramp), mission-critical, safety-critical or regulated systems, Postman or SOAP UI, JSON and log analysis, AI-DLC practices, AI-powered or agentic software
