EJ 1516 Senior Full Stack Developer

Role Summary
Softobiz is looking for a Senior MERN Stack Developer to join the engineering team. You will be responsible for designing and delivering end-to-end features across our Node.js backend and React frontend, taking ownership from API design through to UI delivery. This role is being hired to backfill a departing team member, so the ideal candidate can ramp up quickly and take over an existing area of the codebase with minimal disruption to delivery. AI-based development is central to how the engineering team works. We are specifically looking for someone well versed in AI-assisted development - comfortable using AI coding assistants as part of their daily workflow to design, build, test, and ship features faster and with higher quality.
Key Responsibilities
Backend Development
Design and implement RESTful APIs using Node.js and Express, with clean, well-tested, maintainable code.

Integrate with third-party services and internal systems, handling authentication, validation, and error management. Frontend Development
Build and maintain complex front-end applications using React, including state management, component testing, and performance tuning.
Collaborate closely with product management, design, and QA to define requirements and deliver high-quality features.
AI-Assisted Development
Use AI coding assistants (Claude Code, GitHub Copilot, Cursor, or similar) as a core part of the daily development workflow - for code generation, refactoring, review, and test creation.
Apply AI-assisted approaches to accelerate feature delivery without compromising code quality or test coverage.
Share learnings and best practices on AI-assisted development with the wider team.
Quality, Delivery & Operations
Drive best practices in code quality, testing, and CI/CD across the codebase.
Troubleshoot production issues and lead performance optimization efforts.
Take end-to-end ownership of features, ensuring consistency and reliability across the full stack.
