Fullstack Engineer - RentOk
Location: On-site, Gurugram (Sector 27)
About RentOk:
RentOk is a property management SaaS platform used by thousands of landlords and property managers across India to run their business - rent collection, tenant management, expenses, payments, communication.
Our stack is Node.js/TypeScript on the backend, Next.js on the web, and PostgreSQL on Azure as the core data layer. Engineering here means owning things end-to-end - from schema design to the API to the UI - and being accountable for what goes to production.
About this role:
This is a backend-heavy fullstack role. You'll spend the majority of your time in Node.js and PostgreSQL - designing schemas, writing APIs, handling payment webhooks, building async job pipelines. You'll also build and ship web interfaces in Next.js when the feature demands it.
You won't have a separate backend team to hand off to or a DBA to consult. You write the query, you profile it, you fix it.
What you'll work on:
- Payment and transaction infrastructure - webhook processing, idempotency, reconciliation, payout flows across multiple gateways
- Multi-tenant data architecture - schema design, data isolation, performance at scale
- APIs consumed by web and mobile clients - clean contract design, versioning, error handling
- Async job pipelines - Redis for caching, notifications, and crons for scheduled workflows
- Web interfaces in Next.js - near pixel-perfect frontend, but functional, shippable product surfaces
What we're looking for:
Must-haves:
- 2 - 4 years of experience building production backend systems in Node.js + TypeScript
- Strong PostgreSQL fundamentals - you write raw SQL, understand query plans, and know when your ORM is lying to you
- Experience building and maintaining REST APIs at real user scale
- End-to-end ownership instinct - you've shipped features from spec to production
- Comfort with async patterns - queues, retries, idempotency, race conditions
Strong signals:
- Payment domain exposure - UPI, gateway webhooks, reconciliation, settlement flows
- Multi-tenant SaaS context - you've thought about data isolation, tenant-level configs, shared infra
- You've debugged a production incident under pressure
Nice-to-haves:
- Experience with BullMQ, Redis, or similar queue infrastructure
- Observability discipline - structured logging, query profiling
- AI tooling in your day-to-day (Claude Code, Cursor, Copilot)
- B2B SaaS or India-market product experience
- Next.js exposure
What we explicitly don't require:
- A CS degree from a specific tier of college
- FAANG or large-company experience
- DevOps or cloud infrastructure expertise
How we work:
- On-site in Gurugram (Sector 27), 6-day week with alternate Saturdays off
- Bi-weekly release cycle, every alternate Thursday
- Real product, real customers, real revenue
- Small EPD team (~10 engineers), tight feedback loops, low process overhead
- We use Claude Code, Cursor, GitHub MCP, and other modern AI tooling in our day-to-day engineering
