About this role
About the role We're looking for a
strong full-stack Engineer who takes real ownership — someone who can take a feature from a Figma screen all the way to a deployed, production-ready API and UI on a
Next.js + TypeScript front end backed by a
Node.js / Express + MongoDB API, with real-time features, background jobs, and payments. We're not after someone who just closes tickets — we want a builder who thinks about edge cases, performance, and the user, writes clean code others can build on, and moves fast without leaving a mess behind. Whether you're fresh out of standout projects or have a couple of years under your belt, what matters is the quality of what you ship and how quickly you grow.
What you'll do
- Build features
end to end — UI in
Next.js / React / TypeScript , APIs in
Node.js / Express , and data models in
MongoDB / Mongoose .
- Design and consume
REST APIs , handling auth, validation, pagination, and error states properly.
- Build polished, responsive UI with
Tailwind CSS + shadcn/Radix ,
React Hook Form + Zod , and clean state management (
Redux Toolkit / TanStack Query ).
- Work with
real-time features (Socket.io),
caching/queues (Redis), and
background/scheduled jobs .
- Integrate third-party services —
payments (Razorpay), email (AWS SES), notifications, file storage .
- Write
tests (Jest / Vitest + Testing Library) and care that your code holds up in production.
- Own features in production — debug across the stack, watch logs and errors, and keep performance and quality high.
- Think through trade-offs, push back when something doesn't make sense, and help raise the bar on code quality.
- Collaborate with design, product, and other engineers — and ship regularly.
What we're looking for
- 0–2 years building web apps (internships, standout personal/production projects, or freelance all count) — and a genuine
drive to build and ship .
- Strong programming fundamentals — data structures, problem-solving, and the ability to reason about why your code works, not just that it does.
- Strong
JavaScript / TypeScript — TypeScript is our default; you're comfortable with types, interfaces, and generics, not fighting them.
- Solid with
React (ideally
Next.js ) — components, hooks, state, and an eye for clean, reusable UI.
- Can build real backend APIs with
Node.js / Express — routing, middleware, auth, and sensible structure.
- Comfortable modeling and querying data —
MongoDB/Mongoose ideally (SQL fine), with awareness of indexes and performance.
- Solid grasp of
REST API design ,
authentication (JWT/sessions) , async patterns, and handling failure gracefully.
- Strong
Git workflow and a habit of writing clean, readable, well-structured code.
- Able to take a feature from
concept to deployment on your own — and care that it actually holds up.
