Senior Full-Stack Software Engineer (React & Spring Boot)

About the role

Space42 is looking for a Senior Engineer in Software Development who will lead full-stack delivery across its projects, owning both the React frontend and the Java (Spring Boot) backend outside the dedicated critical-client engagement, which is supported by embedded specialists. The role covers end-to-end feature delivery, from design and development through testing and deployment, and works across several concurrent projects.

Key responsibilities

• Design, build and maintain features end-to-end across React and Spring Boot, adapting to each project's architecture
• Maintain and extend frontend state management without introducing conflicting patterns
• Ensure data integrity and correct transaction boundaries across concurrent backend operations
• Diagnose and fix issues across the full stack, from frontend rendering and state bugs to backend concurrency and performance
• Profile and improve performance under real usage, not synthetic benchmarks
• Make sure UI changes meet WCAG accessibility standards
• Work on the relational database layer (schema changes, query performance, migrations) with production-safe practices
• Design and consume REST APIs, owning both sides of the contract
• Collaborate with Product Managers, Engineers and Designers in Agile/Scrum, and apply change-management discipline suited to each project's risk profile

Required profile

• Strong React experience (5+ years) with deep understanding of state architecture at scale
• Strong Java experience (5+ years) with concurrency, thread safety and locking
• Solid grasp of transaction boundaries and data integrity in multi-user systems
• Experience with Spring Boot and strong SQL and relational database experience
• Track record of diagnosing and improving performance on both frontend and backend
• Comfortable reading and extending unfamiliar codebases and working across multiple projects

Required skills

• React, state management patterns, Spring Boot
• Java concurrency (java.util.concurrent)
• SQL, schema design, query tuning, migrations
• REST API design, WCAG accessibility
• Nice to have: AI-assisted coding tools (GitHub Copilot, Cursor, Claude Code) and Python

What we offer

• Competitive compensation packages and comprehensive medical insurance
• Well-being initiatives and resources
• Exclusive discount programs across the UAE
