Senior Product Engineer - Full Stack

About the job:

Role: Senior Product Engineer - Full Stack

Location: Remote / Chennai

Job Type: Full-Time

Experience: 5+ years mandatory

Start Date: Immediate

Screening Priority: Proven leadership and end-to-end product and mobile app development experience in startup environments.

About the role:

We’re building a mobile-first hyperlocal super app that unifies commerce, services, logistics, and payments into a single operating system.

This is not a feature-shipping role.

This is a 0→1, founder-level engineering role — where you will:

• Architect systems from first principles
• Ship end-to-end products independently
• Own critical decisions across product, engineering, and scale

You will work directly with the founder and operate as a full-stack owner, not a contributor.

Perks:

• Work from anywhere. Own your time. Deliver outcomes. Fully remote with flexible hours, with occasional travel as required
• Work from Bali, Thailand, Vietnam, etc — on us. Sponsored overseas workcation after one year (flights + stay covered) for 2 weeks.
• Not your typical offsites. Milestone-based team experiences (India + overseas) — escape rooms, private chef dinners, race track days
• Build with the best tools. Premium hardware + access to leading AI tools (e.g., Claude Pro/Max)
• Real ownership from day one. Shape product and technical decisions directly
• Grow into leadership. Clear path to Head of Engineering
• See the full picture. Direct exposure to product, GTM, and scaling decisions
• Stability + ambition. Backed by a public limited company with startup-level ownership

What You’ll Build:

You will design and ship core systems such as:

Merchant Onboarding

• KYC, verification, compliance workflows

Hyperlocal Discovery

• Tools that power real-world execution at scale
• Geo-based ranking, density optimization, supply-demand matching

Internal Ops Systems

• Tools that power real-world execution at scale

What You Own:

Build production-grade systems from scratch

Translate ambiguous ideas → architecture → shipped product

Own the entire lifecycle:

• Design → Build → Deploy → Monitor → Iterate

Make high-stakes technical decisions independently

Design systems that scale across:

• Commerce (food, grocery, retail)
• Services (home services, salons, etc.)
• Logistics + financial flows

System Design & Architecture:

• Design system architecture from first principles based on product needs
• Make pragmatic trade-offs between speed, scalability, and complexity
• Build systems that handle real-world constraints (data inconsistency, async workflows, geo-based logic)
• Model data effectively across SQL and NoSQL systems
• Evolve architecture over time as the product and scale grow

Tech Expectations:

Frontend (React Ecosystem):

Deep expertise in React + Next.js (App Router)

Strong grasp of:

• SSR, SSG, ISR, edge middleware
• Advanced patterns (compound components, hooks architecture)

State management judgment:

• Zustand / Redux Toolkit / React Query — knows when to use what

Performance-first mindset:

• Rendering strategies, lazy loading, bundle optimization

Backend (Node.js)

Strong experience with Node.js + Typescript

Ability to design:

• Scalable REST APIs (versioning, rate limiting, fault tolerance)

Experience with:

• Distributed systems
• Event-driven architectures / queues (BullMQ, RabbitMQ, etc.)

Writes clean, maintainable, production-grade code

Data & Systems Design:

Strong fundamentals in:

• Schema design (SQL + NoSQL)
• Indexing, performance, trade-offs

Experience with:

• PostgreSQL / MySQL / MongoDB / Redis

Understands:

• Caching strategies
• Data consistency vs speed trade-offs

Auth & Security:

Hands-on with:

• JWT, OAuth2, session management, refresh tokens

Builds:

• RBAC and permission systems

Solid understanding of:

• CORS, CSRF, injection risks, secrets management

Nice to Have (High Leverage):

• Exposure to Python (FastAPI / Django / Flask)
• Familiarity with mobile (React Native / Flutter)
• Experience with AI tooling (Copilot, Claude, etc.) as a thinking partner — not a crutch

Product Mindset (Non-Negotiable):

• Thinks in systems, not tickets
• Can convert vague ideas → structured execution
• Challenges assumptions before building
• Operates with high ownership and zero hand-holding
• Optimizes for speed and correctness

Deployment & Production Ownership:

Comfortable with:

• CI/CD (GitHub Actions, etc.)
• Cloud platforms (AWS / GCP / Vercel / DO)

Sets up:

• Monitoring, logging, alerting (Sentry, Datadog, etc.)

Handles:

• Production incidents, debugging, rollback strategies

Who This Is For:

You’ll thrive if:

• You’ve built 0→1 products in the real world
• You enjoy owning entire systems, not parts
• You move fast without waiting for instructions
• You’re comfortable with ambiguity and responsibility

Who This Is NOT For:

• Engineers who need detailed specs for everything
• Resume-driven “stack collectors”
• People looking to contribute to a small module

Why This Role Matters:

You’ll help build a super app architecture (rare, complex, high impact)

Work across multiple real-world systems:

• Commerce + services + logistics + payments

Direct exposure to:

• Product strategy
• GTM
• Real scaling challenges
