  • Strong proficiency in at least one programming language commonly used for AI development (Python, JavaScript, TypeScript).
  • You have deployed at least one AI Agent to production, with a deep understanding of the entire development lifecycle — from initial concept to final deployment with customer feedback loops.
  • You have experience leading a team of engineers, especially in growth-focused environments.
  • Hands-on experience with AI frameworks and tools, such as OpenAI, Anthropic, Hugging Face, LangChain, and vector databases.
  • Strong understanding of NLP, ML, and LLM fundamentals - including modern LLM technologies, RAG, and prompt engineering techniques.
  • A desire to work in an environment which values speed of iteration and individual autonomy, while also embracing personal accountability and the ability to collaborate effectively as part of a dynamic team.

Requirements

  • Bonus points: You have contributed to open-source AI/ML projects.

Benefits

  • Fully remote: work from anywhere in the world!
  • Autonomy and trust to do your job: we care about outcomes over everything else.
  • Paid time away: all employees are given 35 days of PTO annually. We also offer a paid sabbatical after 5 years.
  • Generous U.S. benchmarked compensation and startup equity no matter where you are in the world.
  • Awesome medical coverage with 100% coverage for you and your family, or medical reimbursement options where applicable!
  • Parental leave for parents expanding their family, or just starting one.
  • Home office stipend to help you get up and running.
  • Learning & development stipend to help you level up your professional skills.
  • Annual bonus potential for roles that don't already receive variable income or commission.
