Our team is small, engineering-driven, and consists of top operators who’ve worked at Amazon, Alibaba, and even one guy who worked directly for the CTO of Affirm and the founder of eBay.

  • Write clear documentation, share your expertise with other engineers.
  • [Optional] Expand features and improve the reliability, accuracy, and speed of our LLM orchestration.

Requirements

  • 3-5 years of experience building robust and performant backend systems using modern technology. We use Python, FastAPI, asyncio, OAuth2.0, Pub/Sub (Protobuf), and Google Firestore (NoSQL).
  • Deep understanding of backend development best practices, including system design, performance optimization, async frameworks, and scalable architecture.
  • Take initiative and get things done.
  • Quickly evaluate tradeoffs and make sound technical decisions in a fast-paced, changing, and often unclear environment.
  • Proficient in English with strong communication and collaboration skills (we perform deep integrations with external APIs and most of the documentation you encounter will be in English).

We Offer

  • Up to 8000 USD (annual salary)
  • Full-time position
  • Opportunity to work in a fast-growing startup environment
