We are hiring a high-impact Staff Engineer / SDE-3 to build and scale core backend systems, product architecture, and platform infrastructure for a fast-growing AI-first startup. This is a hands-on engineering role for builders who have worked in strong product/startup environments and enjoy solving large-scale engineering problems across backend systems, distributed architectures, APIs, cloud infrastructure, and product scalability. You will work closely with founders, product, and engineering leadership to drive architecture decisions, ship production-grade systems, and help scale engineering from the ground up.
Responsibilities:
- Design and build highly scalable backend systems and APIs.
- Drive architecture decisions across backend and full-stack systems.
- Optimise system performance, reliability, scalability, and developer productivity.
- Build clean, maintainable, production-grade code with strong engineering standards.
- Collaborate closely with product and founders on 01 and scale-stage initiatives.
- Mentor junior engineers and contribute to engineering culture/processes.
- Improve observability, deployment workflows, and infrastructure reliability.
- Work across backend, infra, and occasionally frontend layers when needed.
Requirements:
- Strong backend engineering fundamentals with the ability to build scalable production systems.
- Experience working in Series A+ / high-growth product startups.
- Ability to independently own architecture, design, execution, and scaling challenges.
- Strong understanding of distributed systems, databases, APIs, performance optimisation, and cloud infrastructure.
- Comfortable operating in fast-moving, high-ownership startup environments.
- Product-thinking mindset, not just ticket execution.
- Ability to mentor engineers and raise engineering quality across teams.
- Tier-1 CS pedigree (IITs / NITs / BITS / top institutes) is a strong plus.
Tech Stack:
- Backend: Node.js, Next.js .
- Frontend: React.js, TypeScript.
- Database: PostgreSQL.
- Cloud and infrastructure AWS.
Must Have Skillset:
- Strong expertise in backend development using Node.js .
- Strong understanding of system design and distributed systems.
- Production experience with React + TypeScript.
- Strong SQL and PostgreSQL fundamentals.
- Experience building scalable cloud-native applications on AWS.
- Strong API architecture and asynchronous systems understanding.
- Experience working in product startups at scale.
