MERN Developer

Overview
We are seeking a hands-on Senior Backend / MERN Developer to design, develop, and maintain scalable backend services that support a growing marketplace and API-driven platform. This role is backend-focused and ideal for a senior engineer with deep experience in Node.js, MongoDB, and TypeScript, who enjoys working within established systems while helping modernize and scale them for future growth. The ideal candidate brings strong backend judgment, experience stepping into existing platforms, and a collaborative, team-first mindset.

• Contribute to backend architecture discussions and technical decision-making
• Support platform modernization and migration efforts within an existing codebase

• Collaborate closely with product, QA, and globally distributed engineering teams
• Follow best practices across SDLC, testing, performance optimization, and secure coding
• Utilize CI/CD pipelines to support automated builds, testing, and deployments
• Communicate progress, risks, and technical tradeoffs clearly within the team
• Stay current with evolving backend technologies and tooling, including emerging AI-assisted development tools
