Senior Engineer - Software Development

Job Description As a Senior Engineer – Software Development will lead full-stack software delivery across Space42 projects, taking ownership of both React frontend and Java (Spring Boot) backend development outside the dedicated critical-client engagement, which is supported by embedded frontend and backend specialists. The role is responsible for the end-to-end delivery of features, from design and development through testing and deployment, with accountability for both sides of the technology stack without reliance on a counterpart engineer. The Senior Engineer will work across multiple concurrent projects, adapting to each project's existing architecture, development standards, and technical conventions while ensuring consistent, high-quality outcomes. They will proactively embed data integrity, performance, accessibility, and maintainability into solutions from the outset, ensuring robust and scalable systems. In addition, the role will collaborate closely with engineering leads, architects, and project-specific teams to align shared engineering standards, best practices, and development methodologies across the organization. Responsibilities • Design, build, and maintain features end-to-end across the React frontend and Java (Spring Boot) backend, adapting to each project's established architecture • Maintain and extend frontend state management approaches without introducing conflicting patterns • Ensure data integrity and correct transaction boundaries across concurrent backend operations • Diagnose and resolve issues across the full stack, from frontend rendering and state bugs to backend concurrency and performance issues • Profile and improve performance across the stack under real usage, not synthetic benchmarks • Ensure UI changes meet accessibility standards (WCAG) as a built-in requirement, not an afterthought • 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 between frontend and backend • Collaborate with Product Managers, Engineers, and Designers in Agile/Scrum on whichever project you're supporting • Apply change-management discipline appropriate to each project's risk profile, whether early-stage or already in production Qualifications • Strong React experience (5+ years) with a deep understanding of state architecture in non-trivial applications component state, context, and state management patterns at scale • Strong Java experience (5+ years) with a deep understanding of concurrency thread safety, locking, and race conditions the java.util.concurrent toolkit • Solid grasp of transaction boundaries and data integrity in multi-user systems • Experience with Spring Boot for building backend services • Strong SQL and relational database experience (schema design, query tuning, migrations) • Track record of diagnosing and improving performance under real usage, on both the frontend and backend • Solid grasp of web accessibility standards (WCAG) and how to implement them, not just audit for them • Comfortable reading and extending an existing, unfamiliar codebase across both stacks • Strong understanding of REST API design, both building and consuming, including request/response contracts Additional Requirements • Comfortable working across multiple projects with different codebases, conventions, and risk profiles, rather than being embedded full-time on one • Comfortable adapting to each project's existing architectural patterns rather than imposing a single standard approach everywhere • Demonstrated full-stack capability, with end-to-end ownership of frontend and backend features across all assigned projects. • Coordinates with, but does not report into, project-dedicated engineers; shares standards and practices rather than a reporting line NICE TO HAVE • Experience using AI-assisted coding tools (e.g. GitHub Copilot, Cursor, Claude Code) to accelerate delivery across projects, while retaining full ownership and review of what ships • Python experience Our Benefits & Perks • Competitive compensation packages and comprehensive medical insurance to support you and your family. • Well-being focused initiatives and resources, designed to enhance your personal and professional life. • Access to exclusive discount programs, offering savings across various lifestyle and leisure experiences across the UAE.
