  • Develop production-ready LLM and ML features (e.g., document classification, predictive maintenance, AI assistants), including prompt engineering, fine-tuning, and deployment
  • Closely collaborate with the founders – you decide on architecture, tools, frameworks, and set technical standards (clean code, testing, code reviews, DevOps processes)
Requirements

We're looking for someone who:

  • Has deep experience with backend systems, infrastructure, and API design
  • Thrives in early-stage environments where speed and adaptability are key
  • Enjoys solving complex technical challenges with an eye toward scalability and maintainability
  • Is comfortable working in-person with the founding team (not full-time remote)
  • Wants to take ownership—both in equity and in decision-making
