Fullstack Engineer

• *This role is for one of our clients**

Company Name: RentOK

Industry:Technology, Information and Internet

Seniority level: Associate level

Experience: 2\+ yrs

Location: Gurugram

Job Type: full\-time

• *About the role**
• -----------------

#### **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 (not demo projects)

End\-to\-end ownership instinct — you've shipped features from spec to production, not just implemented tickets

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 and can tell the story clearly

• *Nice\-to\-haves**

Experience with BullMQ, Redis, or similar queue infrastructure

Observability discipline — structured logging, query profiling, knowing what to instrument before things break

AI tooling in your day\-to\-day (Claude Code, Cursor, Copilot) — we use these actively

B2B SaaS or India\-market product experience

Next.js exposure — you're not a frontend specialist, but you can ship a working page

• *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 — nice to have, not load\-bearing

#### **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 — your backend decisions affect transaction reliability directly

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
