About the Role

Senior Fullstack Developer (MERN) - Team Lead

Experience: 7+ years

Work Mode: Work from Office / Hybrid - US shift, 5 days/week

Budget: Open (market-competitive, to be finalized based on candidate quality)

About the Role

We’re hiring a Senior Fullstack Developer (MERN) who can own projects end-to-end - from client discovery through architecture, development, team leadership, and production launch. This is a hybrid IC + leadership role: you’ll write and review code, lead a small team, interface directly with US-based clients, and drive AI-augmented development practices across the team.

Key Responsibilities

Technical Ownership

• Own full project lifecycle: requirement gathering → architecture → development → deployment → post-launch support
• Design scalable system architecture for MERN-based applications (MongoDB, Express.js, React, Node.js)
• Make key technical decisions on stack, infrastructure, and integrations
• Conduct code reviews, enforce coding standards, and ensure technical debt stays manageable
• Troubleshoot complex production issues and lead root-cause resolution

Team Leadership

• Lead and mentor a team of 3-8 developers (fullstack/frontend/backend)
• Plan sprints, distribute tasks, and track delivery against timelines
• Conduct 1:1s, performance feedback, and technical upskilling for the team
• Act as the technical point of escalation for the team

Client & Stakeholder Management

• Lead client discovery calls - translate business requirements into technical scope
• Prepare and own client-facing documentation: SOWs, technical specs, architecture diagrams, project status reports
• Manage client communication independently during US working hours
• Handle scope discussions, timeline negotiations, and expectation management

Product Delivery

• Drive products from concept to live launch, including go-live checklists, deployment pipelines, and rollback plans
• Own post-launch monitoring, performance optimization, and iteration cycles

AI-Driven Efficiency

• Actively use AI tools (GitHub Copilot, Claude, ChatGPT, Cursor, etc.) to accelerate development, code review, testing, and documentation
• Build/streamline internal workflows using AI to improve team velocity
• Evaluate and introduce new AI tooling where it improves delivery speed or quality

Required Skills

• Frontend: React.js (advanced), Redux/Context API, TypeScript, HTML5/CSS3, responsive design, performance optimization
• Backend: Node.js, Express.js, RESTful API & GraphQL design, microservices architecture
• Database: MongoDB (schema design, aggregation, indexing/performance tuning), Redis (caching)
• Cloud & DevOps: AWS/Azure/GCP, Docker, CI/CD (GitHub Actions/Jenkins), basic Kubernetes exposure
• Architecture: System design, scalability planning, security best practices (OWASP), API gateway/load balancing concepts
• Leadership: Sprint planning, code review ownership, mentoring, cross-functional coordination
• Client-Facing: Requirement discovery, technical documentation (SRS, architecture docs, SOWs), client communication in a US business context
• AI Tooling: Practical, daily use of AI coding/productivity tools - not just awareness

Nice to Have

• Next.js, Nest.js
• Experience with client billing models (T&M, fixed bid)
• Prior experience in an agency/services environment handling multiple client projects
• PMP/Agile certification
• Experience setting up engineering processes from scratch (0-to-1 team building)
