Job Description – React Native Full Stack Developer

About the Role

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

• Exposure to CI/CD pipelines

• Experience with Docker, NoSQL databases, or distributed caching

• Experience integrating third-party REST/SOAP APIs

• Experience in a fast-moving startup environment

Why SwitchKart

• Real ownership over architecture and technical direction.

• Access to the latest AI coding agents and tools — we invest in keeping our engineers on the cutting edge.

• 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.

Brewhackers Technologies is a place for creative people to develop themselves and thrive in a rapidly changing world. We are developing a service to help people consume and share ideas that matter faster and more efficiently. We deliver this through an app for iOS and Android.

We are small team so :

• Passion for the problem is our secret sauce. At a startup, everyday is a struggle but we get through that by keeping our eyes on the prize.
• We find a way or make a way. No excuses.
• We thrive in uncertainties. We have more questions than answers and more opportunity to learn new things.
•  

Our tech stack is made of :

We are looking for a full-stack engineer with a passion for product and delivery. This is the type of job where you are pushed in cold water and you have to learn to swim by yourself. Your personality and your traits matter more than your tech expertise:

• We are looking for an independent, responsible person. Mainly because there is no time for micro-management. We expect you to be able to carry your own weight and be a reliable partner.
• We are looking for a fast learner. We may need to use technologies that you never used before. That should not scare, but excite you. In most cases we may not even know what we need and you may have to propose something.
• We are looking for you to get stuff done. We work in weekly sprints because we believe in consistent delivery over big lengthy releases.
• We want you to be proactive. We appreciate conviction way more than consensus. Words are nice, opinions are cute … but proactivity in action is golden.
• We want you to be a partner for your colleagues in the dev team. Help or lead the planning process, code reviews, commits etc. Provide guidance and help your colleagues when they get stuck.
• We want you to be an over-communicator. We are remote-first and it’s up to you to show your work, explain your ideas or highlight problems.

Now on technology, these would be nice:

• Experience with Javascript.
• Experience with mobile development (native or hybrid)
• Experience with interface building frameworks (React, Angular, Vue etc)
• Experience with Node.JS, Express Framework and GraphQL
• Experience with SQL and NoSQL databases
