Eligible candidates have 5–8 years of backend experience, hands‑on NestJS in production, and proven ability to handle traffic spikes while maintaining performance and reliability.

Qualifications

• 5–8 years in backend engineering with 2–3 years NestJS in production

Responsibilities

• Design and build NestJS services serving reader and newsroom traffic
• Ensure reliability during traffic spikes via caching, autoscaling and graceful degradation
• Model data across MongoDB and relational stores with proper indexing and query plans
• Secure authentication surface: login, sessions, SSO, roles and permissions
• Implement personalization signals, ranking and experiments for readers
• Own end-to-end caching contract from Redis to CloudFront and purge-on-publish
• Build APIs for mobile and web teams and improve developer experience

Job description

Role Overview

Build the services behind Patrika’s newsroom and reader products — APIs that stay fast and available when a story breaks and traffic multiplies within minutes. This is a backend‑weighted fullstack role: NestJS and TypeScript in production, MongoDB and a relational store, AWS, auth, caching from Redis to CloudFront, and a pager you have actually carried.

What You’ll Work On

• Design and build NestJS services in TypeScript that serve both reader-facing and newsroom-facing traffic.
• Keep the platform standing when a story breaks — caching, autoscaling, backpressure, load shedding and graceful degradation.
• Model data across MongoDB and relational stores, and own the indexes and query plans that keep reads fast at volume.
• Build and secure the authentication surface: login, sessions, SSO, entitlements, roles and permissions.
• Ship personalisation — the signals, the ranking and the experiments behind what each reader sees.
• Own the caching contract end to end, from Redis to CloudFront, including purge‑on‑publish when a story is corrected or pulled.
• Build the APIs the mobile and web teams depend on, and treat their developer experience as part of the job.
• Instrument everything: tracing, metrics, SLOs and alerts that page a human only when a human is needed.
• Take part in on‑call, write honest incident reviews, and fix the class of problem rather than the instance.

Who Is Right for This Role

• 5–8 years in backend engineering, including at least 2–3 years hands‑on NestJS in production.
• Writes real TypeScript — typed services, dependency injection, decorators — not JavaScript with a few annotations.
• Has run MongoDB at scale: aggregation pipelines, indexing strategy, explain plans, replica sets or sharding.
• Has genuine relational experience — PostgreSQL or MySQL, transactions, query plans, migrations.
• Can describe a specific traffic spike they handled: the number, what broke, and what they changed.
• Has deployed and operated on AWS — ECS, EC2, S3 and CloudFront.
• Has built proper AuthN and AuthZ: OAuth 2.0 / OIDC, JWT, role‑based access, and at least one SSO integration.
• Has carried a production pager and written up an incident afterwards.
• Can join immediately (0–15 days).

Who Isn’t a Fit

• Has not spent 2–3 years on NestJS in production.
• TypeScript is annotations on JavaScript, not typed services and DI.
• Mongo experience without aggregations, indexes, explain plans, or replica/shard operations.
• No PostgreSQL or MySQL with transactions, query plans, and migrations.
• Cannot describe a specific traffic spike: the number, what broke, and what they changed.
• Has not operated on AWS (ECS, EC2, S3, CloudFront).
• Has not built OAuth 2.0 / OIDC, JWT, RBAC and at least one SSO integration.
• Has never carried a production pager or written an incident review.
• Notice period longer than 15 days.

How You’ll Work

Full‑time contract, remote / flexible (India). Immediate joiners only — notice period 0–15 days. Experience required: 5–8 years.
