Experience: 8+ years

Band - SDE 3

Location: Noida, Uttar Pradesh, India — full-time on-site (no hybrid, no remote)
Department: Engineering — Platform & Product
Reports to: Engineering Manager / Principal Engineer

About the Role
We are looking for a Senior Full Stack Developer to design, build, and scale distributed
backend services and up-to-date web applications. You will own end-to-end delivery —
from API and data modelling through to production operations — across a microservices
platform built on Node.js, NestJS, gRPC, PostgreSQL, Elasticsearch, Redis, and a multi -
cloud footprint spanning Google Cloud Platform and AWS, with React on the front end.
This is a hands-on senior IC role. You will write production code daily, set technical
direction for your services, review others' work, and mentor mid-level engineers.
Key Responsibilities
Backend & Architecture
• Design, build, and maintain scalable microservices using Node.js and NestJS
(TypeScript).
• Define and implement gRPC service contracts (Protocol Buffers) for highthroughput
inter-service communication; maintain backward compatibility across
versions.
• Build and version REST and GraphQL APIs for client-facing consumption.
• Decompose monolithic components into well -bounded services; define service
ownership, contracts, and SLAs.
• Experience with ORMs such as TypeORM or Prisma, and with raw SQL where
performance demands it.
• Implement resilient inter-service patterns: retries, circuit breakers, idempotency,
timeouts, back-pressure, and graceful degradation.
• Design event-driven flows using message brokers (Pub/Sub, Kafka, or RabbitMQ)
— including outbox patterns and exactly-once/at-least-once handling.
Media Delivery, CDN & Video Streaming
• Design, develop, and operate scalable video processing and transcoding
pipelines for VOD and live streaming workflows.
• Implement video ingestion, adaptive bitrate (ABR) ladder generation, packaging
for HLS/DASH, thumbnail generation, previews, and media optimization using
FFmpeg, GCP Transcoder API, or similar encoding platforms.
• Architect and manage CDN delivery infrastructure using solutions such as Cloud
CDN, Cloudflare, Akamai, Fastly, or CloudFront.
• Configure and optimize CDN settings including cache keys, cache-control policies,
TTLs, invalidation workflows, origin shielding, geo-restrictions, signed URLs, and
token-based access control.
• Drive streaming performance improvements through cache optimization, origin
offloading,



multi-CDN strategies, and cost optimization initiatives.
• Develop and maintain media catalog, metadata management, content discovery,
and playback services.
• Build and scale playback APIs responsible for manifest generation, playback
authorization, and entitlement validation.
• Support Live Streaming and VOD platforms, including DVR functionality, catch-up
TV workflows, and low-latency streaming architectures.
Data & Search
• Model relational schemas in PostgreSQL; write and optimise complex queries,
indexes, partitions, and migrations.
• Diagnose and fix query performance issues using EXPLAIN ANALYZE, connection
pooling, and read-replica strategies.
• Design Elasticsearch (or AWS OpenSearch) indices, mappings, analyzers, and
aggregation-heavy queries for search and analytics workloads; own reindexing
and relevance tuning.
• Use Redis — self-managed, GCP Memorystore, or AWS ElastiCache — for caching,
distributed locks, rate limiting, session storage, and queue primitives; define
cache invalidation strategy and TTL policy.
Frontend
• Build responsive, accessible interfaces in React.js with TypeScript, hooks, and
modern state management (Redux Toolkit / Zustand / React Query).
• Optimise front-end performance: bundle size, code splitting, lazy loading,
memoisation, and Core Web Vitals.
• Collaborate with design on component libraries and design-system consistency.
• Write component and integration tests (Jest, React Testing Library).
Engineering Leadership
• Lead technical design reviews and produce clear design documents with explicit
trade-offs.
• Conduct rigorous, constructive code reviews; enforce coding standards and test
coverage.
• Mentor mid-level and junior engineers; grow team capability through pairing and
knowledge sharing.
• Partner with Product, QA, and Design to break down epics, estimate accurately,
and deliver predictably.
• Participate in on-call rotation; lead incident response and write blameless
postmortems.
Required Skills & Experience
• 8+ years of professional software engineering experience, with 5+ years building
production backend services in Node.js / Express.js.
• 3+ years of hands-on NestJS in production — modules,



dependency injection,
interceptors, guards, pipes, custom decorators.
• Strong TypeScript across both backend and frontend.
• Proven experience designing and operating microservices at scale, including
service decomposition and distributed-systems failure modes.
• Production experience with gRPC and Protocol Buffers — schema design,
streaming, versioning.
• Deep PostgreSQL expertise: schema design, indexing, transactions, isolation
levels, query optimisation, migrations.
• Hands-on Elasticsearch: index design, mappings, analyzers, aggregations, cluster
health, and performance tuning.
• Production use of Redis for caching and distributed coordination.
• Solid GCP experience — deploying and running services on GKE or Cloud Run with
managed data services.
• Hands-on AWS experience — EKS/ECS or Lambda, RDS/Aurora, S3, SQS/SNS,
ElastiCache or OpenSearch, IAM roles and policies.
• Comfortable operating in a multi-cloud environment and reasoning about
portability, vendor lock-in, and cost trade-offs between GCP and AWS.
• DevOps competence: Docker, Kubernetes, CI/CD pipelines, Terraform, monitoring
and alerting.
• React.js proficiency — hooks, component architecture, state management,
performance tuning.
• Strong grasp of API design, authentication/authorisation (OAuth2, JWT, RBAC),
and secure coding practices.
• Testing discipline: unit, integration, and end-to-end (Jest, Supertest,
Playwright/Cypress).
• Git-based workflows, trunk-based or GitFlow branching, and disciplined PR
hygiene.
Good to Have
• Experience with Kafka, Google Cloud Pub/Sub, or AWS MSK/Kinesis at high
volume.
• Cloud certification — GCP Professional Cloud Architect/Engineer or AWS
Solutions Architect / DevOps Engineer.
• Experience migrating workloads between cloud providers or running active-active
across regions and clouds.
• Familiarity with Next.js, server-side rendering, and edge caching.
• Exposure to multi-tenant SaaS or OTT/media streaming platforms.
• Implement secure video delivery mechanisms including DRM integration
(Widevine, FairPlay, PlayReady), encryption, entitlement checks, and secure key
management.
• Monitor and improve Quality of Experience (QoE) metrics including startup
latency, buffering ratio, playback success rate, video quality distribution, and
viewer engagement metrics.
• Troubleshoot streaming issues across encoding, packaging, CDN, player, and
network layers.
• Knowledge of BFF patterns.
• Performance and load testing (k6, JMeter, Artillery).
