• Optimize I/O-heavy operations to maximize concurrency and throughput.

4. Data Storage, Pipelines & Caching

• Design relational schemas, write optimized SQL queries, and work with PostgreSQL performance tuning (indexes, partitions, query planning).
• Implement caching strategies, rate limiting, distributed locks, and session storage using Redis.
• Build data validation pipelines and compliance-driven data flows ensuring data correctness and auditability.

5. Security, Reliability & Observability

• Implement authentication, authorization, encryption, and secure API practices.
• Build monitoring, alerting, metrics, and tracing systems using modern observability tools.
• Diagnose production issues, identify bottlenecks, and drive long-term fixes and improvements.

6. Code Quality & Technical Leadership

• Conduct detailed code reviews and ensure engineering best practices across the team.
• Participate in technical roadmap planning, architectural discussions, and system design decisions.
• Mentor junior and mid-level engineers; drive a culture of technical excellence and ownership.

Edit job description

• Create a platform to change the way kids learn: Because company is solving a unique problem, we have the chance to reimagine education. Be it collaboration or puzzles or interactive videos or even 3D experiences, there is a huge scope for innovation. You can help us get there.
• Tackle challenging and impactful problems: You'd jump between product, marketing, internal tools, process — participating in every phase from inception to implementation. Absolutely no boredom.
• Join us at a magical time: We went through Y Combinator, have raised funding and are seeing strong traction with a very lean team. You get to be among the first employees in one of the strongest and most passionate teams in the EdTech space.

So, what will you do as a Full Stack Lead at company?

• As one of the early employees, there will be a lot on your plate. All the time!
• You'll take ownership and build new product features from start to finish. We love to hire ‘Product Engineers’ who care about “why” behind a feature and suggest changes to hit the objectives even better
• You'll build improvements to performance, reliability, and product polish — for example, improving the efficiency and performance of our replicated state systems.
• You will mentor new joiners, review the pull requests and help with expanding the team as we grow

This might be for you if...

• You have strong knowledge of both front and back end technologies
• You have been professionally coding for at least 4 years
• You have worked in a startup and relish the chaos and pressure
• You've built and maintained quality user interfaces that have reached a large audience, ideally while the product is experiencing rapid growth.
• You can readily learn most technologies as you go. To you, technologies are about tools and tradeoffs, not an ideology.
• You care about the business implications of anything you build. You're not just going after cool stuff — you understand the balance between craft, speed, and the bottom line.
• Bonus: You're fluent with Typescript, Python, Go, NodeJS, Postgres, Docker.
• Bonus: You're familiar with multiple frameworks such as React, Django
• Bonus: You understand AWS infrastructure and can put out a fire if one happens
