About the role
We’re looking for a full-stack developer to join our founding team and drive our product development. If you’re someone who thrives on high ownership, can figure stuff out on your own and wants to be part of the zero-to-one journey, this might be for you.
What you’ll do
- Tl;dr code, debug and repeat, but since job descriptions are supposed to be serious stuff, feel free to read on;
- You’ll be responsible for architecture and development of both frontend and backend systems;
- Brainstorm and prioritize features with the product team based on technical feasibility to define the product roadmap;
- Ownership of shipping features from writing the frontend and backend code to making it live;
- Unless you’re the one who writes answers on stackoverflow, your code is going to break so make sure you can come back and fix it;
What makes you a good fit
- If you can write code that works, we should be good but read on (disclaimer: most of what follows is not a hard requirement);
- You have 1-3 years of experience building a product from scratch or being in the initial engineering team of an early stage startup;
- Well versed with front-end technologies like HTML, CSS, Javascript to craft intuitive UIs;
- Worked with React.JS & Redux (or similar frameworks) to build scalable, reusable components;
- You've built backend architectures using Node.js & Postgres (Brownie points if you’ve worked with Redis & Sequelize);
- Deployed applications on AWS using services like RDS, EC2, S3, Cloudfront;
- You can write tests, are great at logging {by great logging we don’t mean embarrassing console logs} & error tracking using tools like Sentry & Travis CI;
- Most of the above is us trying to sound legit about our stack, so if you’ve not worked with some of it & are open to learning or have better ideas, it’s totally cool;
Location: Delhi NCR, India (Remote for now, hybrid model post-covid)
