We are looking for Full Stack Engineers with 5+ years of experience developing cutting-edge web apps from the ground up. You will be responsible for implementing the architecture and core features of our web app as well as maintaining the codebase. Building AI-powered automation, real-time data pipelines and customer facing products. You'll own features end-to-end: design APIs, build frontends, integrate LLMs, optimize databases, deploy to serverless and managed servers.

Key Responsibilities

Backend

• Node.js/TypeScript: NestJS, production APIs, RESTful design, JWT/OAuth, rate limiting, Swagger/OpenAPI

• Async & Queues: Bull/BullMQ, SQS, background jobs, retry logic

• ORMs: Prisma or TypeORM, migrations, relations, transactions

• React/Next.js: TypeScript, hooks/lifecycle, performance optimization

• State Management: Redux/NgRx/Zustand

• Modern Stack: Tailwind/Material/Bootstrap, REST/GraphQL/WebSockets, Jest/Cypress

Database & Caching

• Redis: Caching patterns, session management, rate limiting, pub/sub

AI/ML Integration (Production Required)

• LLM APIs: OpenAI/Anthropic/OpenRouter - prompt engineering, token management, structured outputs, error handling (rate limits/timeouts/retries)

• TTS: Elevenlabs or open-source text to speech models

DevOps

Experience

• LLM features in production (actual API integration with error handling, not demos)

• Features deployed to serverless/AWS and maintained in production

• Tests and documentation as part of your workflow (not an afterthought)
