  • Optimize backend systems for performance, scalability, and reliability at high data volumes.
  • Collaborate with frontend engineers to ensure smooth integration into Next.js applications.
  • Ensure security, compliance, and best practices in API authentication (OAuth, tokens, etc.).
  • Contribute to architecture planning, documentation, and system design reviews.


Required Skills/Qualifications

  • Strong expertise with MongoDB (including Atlas) and schema design.
  • Experience with data vectorization and embeddings (OpenAI, Pinecone, MongoDB Atlas Vector Search, etc.).
  • Proven track record of social media API integrations (Meta, Instagram, Facebook; additional platforms a plus).
