About the Role We are looking for an ambitious Senior Backend Engineer to own our entire backend infrastructure. You won't just write APIs; you will architect a Backend-for-Frontend (BFF) system that drives our mobile app's UI dynamically. You will lead a small team, make high-level architectural decisions, and build scalable systems using NestJS, Redis, and PostgreSQL. Key Responsibilities Architecture Ownership: Design and build the BFF layer that serves dynamic UI layouts to the mobile app. System Design: Architect scalable database schemas, caching strategies (Redis), and background workers (BullMQ) for high-traffic events. Code Quality: Enforce strict TypeScript standards, write comprehensive tests (Jest), and conduct rigorous code reviews. DevOps: Manage deployment pipelines (Docker, CI/CD) and cloud infrastructure (AWS/GCP). Mentorship: Guide junior developers and define engineering standards for the team. Requirements Node.js & NestJS: Expert-level mastery. You understand Dependency Injection, Guards, Interceptors, and Modules deeply. Database Design: Strong SQL (PostgreSQL) skills. You know how to design for scale, use indexes effectively, and manage migrations (TypeORM/Prisma). System Design: Experience with caching (Redis), message queues (RabbitMQ/BullMQ), and microservices patterns. TypeScript: Strict typing is your religion. Testing: Experience writing Unit and Integration tests. Preferred Qualifications Experience with Server-Driven UI or BFF patterns. DevOps experience (Docker, Kubernetes, AWS/GCP). Open source contributions or technical blogging.
