  • Strong PostgreSQL skills and experience with relational data modeling at scale.
  • Familiarity with AI/LLM libraries such as LangGraph or similar.
  • Background building scalable backend systems for communications, messaging, or similar high-throughput platforms.
  • Strong computer science fundamentals (data structures, algorithms, distributed systems).
  • Senior-level experience with a proven track record of delivering complex features independently.

Nice to Have

  • Experience with event-driven architectures using queues and pub/sub systems (e.g. SQS, SNS).
