Senior Backend Engineer (Node.js/TypeScript)

We are looking for Senior Backend Engineers to implement the core APIs and features for a white-label platform that enables creators to launch branded mobile apps aggregating content from YouTube, Twitch, Instagram, TikTok, Twitter/X, with exclusive content, free messaging, and livestreams.

Duration: 9-12 weeks MVP, with long-term potential (Phase 2+ payments, advanced features).
 

Key responsibilities:

• Build REST APIs for social feed aggregation/normalization (5 platforms → unified JSON), content CRUD (S3 secure upload, thumbnails, scheduling), free WebSocket messaging (text/image/voice notes, delivery/read receipts), Firebase push notifications (deep links), livestream URL/status management (YouTube/Twitch APIs).
• Implement background workers: hourly social sync, analytics aggregation (subscriber growth, content engagement, DM stats), AWS Rekognition moderation queue, media processing callbacks.
• Design PostgreSQL schemas for multi-tenant data (creator isolation), Redis for caching/pubsub.
• Write clean, testable code with unit/integration tests, contribute to OpenAPI 3.0 documentation.
   

Requirements:

• 4+ years Node.js/NestJS TypeScript production experience, REST API design.
• Hands-on with social media APIs (YouTube Data API, Twitch Helix, etc.), OAuth flows.
• WebSocket real-time experience (chat/messaging), AWS S3 media handling.
• PostgreSQL + ORMs, Redis caching/pubsub, job queues (Bull/Agenda/BullMQ).
• Docker basics, Git workflow.
• English B1+ (code reviews, docs, team syncs).
   

Nice to have:

• Firebase FCM push notifications.
• Background processing at scale, OpenAPI specs.
• Esports/media platforms, real-time systems experience.

What we offer:

• Real App Store product impact — platform powers creators' fan apps
• Modern stack: Node.js/NestJS → PostgreSQL/Redis → AWS S3/ECS → Firebase
• Senior team context: Tech Lead Architect, 2nd Backend, Frontend, DevOps (AWS cert), QA, PM
• Long-term roadmap after MVP (Phase 2 payments/subscriptions, native livestream)
• Remote/hybrid (Ivano-Frankivsk), flexible hours
   

Technical challenges you'll own:

• 5 social APIs → unified feed (hourly background sync, caching strategy)
• Production WebSocket messaging (delivery guarantees, read receipts)
• Multi-tenant content isolation (creator data separation)
   

Let's build the next-generation creator platform together! 🚀
