SwitchKart is on a mission to make technology more accessible and more sustainable — we're in the business of recommerce, giving old smartphones a second life, cutting down e-waste, and extending the lifecycle of every device we touch.
We're looking for a Senior Full Stack Developer to help us build and scale the ecosystem of platforms powering this mission — from our procurement app to our retailer app, pricing engines, and warranty systems. You'll take ownership of complex features end-to-end, mentor junior engineers, and make architectural decisions that shape how we grow.
What You'll Do
• Own Features End-to-End: Design, build, and ship full stack features across our procurement, retailer, pricing, and warranty platforms — from database schema to UI polish.
• Drive Architecture: Make key technical decisions on system design, scalability, and code structure as our ecosystem of apps grows.
• Build AI-First: Design and build systems with AI at the core — not bolted on. Think about where AI can automate, assist, or enhance the products you're building from day one.
• Build Scalable Architecture: Build and monitor a highly performant, failure-resistant platform — we take pride in doing this with a small, high-ownership team.
• Automate and Integrate: Develop tools that automate our integration processes and build data pipelines across our app ecosystem.
• Foster Technical Excellence: Champion unit and integration testing and lead meaningful code reviews across the team.
• Prototype and Validate: Create interactive prototypes to prove out technical concepts and participate in pilots for new initiatives.
• Mentor the Team: Guide junior developers through code reviews, pairing, and technical direction.
• Report Upward: Provide regular updates to management on milestones, risks, issues, and mitigation plans.
• Collaborate Cross-Functionally: Work closely with product and design to translate requirements into robust technical solutions across multiple products.
What We're Looking For
Must Have
• 4+ years of full stack development experience
• Strong proficiency in React and Node.js
• Solid experience with PostgreSQL or MySQL — schema design, query optimisation
• Experience designing and scaling production systems
• Experience deploying and managing applications on a cloud platform (AWS/GCP or similar)
• Comfortable owning a feature from concept to deployment
• Strong debugging and problem-solving skills
Good to Have
• Experience mentoring or leading junior engineers
• Track record of driving scalability and time-to-market in past cloud architecture decisions

• Work on a genuinely differentiated business with measurable impact.
• Be part of a lean team where your decisions shape the product.
• Opportunity to mentor and grow the engineering team.
What we need:
• Experience in both Web + Mobile development
• Strong understanding of APIs & system design
• Ability to build end-to-end features
· Maintain version control and documentation using Git / GitHub.
Roles and Responsibilities
- Design and develop responsive web applications using React.js / Next.js.
