    Our expectations of you

    Qualifications

    • You've worked in early-stage startups or scale-ups where you had to wear multiple hats (coding, testing, UI, integrations).
    • You actively use AI coding tools like Cursor, Codex, or Claude in your daily workflow - and you can talk about how and why.
    • You're comfortable with ambiguity and high ownership: you'll manage multiple projects simultaneously and organize your own delivery.
    • You came from software engineering and have deliberately moved into AI.
    • Strong Python skills: you can actually code, not just prompt.

    Experience

    • You have 5+ years experience in Software Engineering and AI.
    • Hands-on experience building with LLMs (OpenAI, Anthropic, or similar): APIs, prompt engineering, structured outputs, agent frameworks (LangChain, LangGraph, or similar).
    • Experience with RESTful APIs, cloud services, and testing/QA for AI systems.
