We’re looking for a highly curious and hands-on AI Engineer to help us build and continuously improve intelligent workflows inside our product. This role sits at the intersection of model experimentation, AI-first product thinking, and full-stack implementation.
You’ll work closely with the founders to prototype, integrate, and optimize the use of LLMs and other AI systems across our platform. This is a technical, creative, and fast-moving role ideal for someone who thrives in an experimental environment and uses AI tools daily.
What You’ll Do
- Prototype and implement intelligent workflows powered by foundation models (OpenAI, Claude, Gemini, etc.)
- Explore and integrate multi-step reasoning using Chain-of-Thought and agent-style patterns
- Fine-tune open-source models or run prompt tuning experiments to improve task accuracy
- Use tools like Cursor and Windsurf to prototype and iterate quickly on product
- Work across the stack to integrate AI features (Node.js + Supabase + React)
- Run micro-model evaluations to test hypothesis-to-output cycles
- Use AI to augment your own workflow and automate internal tooling
- Contribute to our experimentation engine for evaluating which models to use where
- Implement AI Voice agents
Required qualifications:
- Experience working with foundation models (OpenAI, Gemini, Claude, Mistral, etc.)
- Deep understanding of prompt engineering, reasoning chains, agent orchestration, and tool calling
- Hands-on experience with model fine-tuning and working with vector stores
- Proficiency in Cursor or Windsurf (daily usage preferred)
- Strong backend knowledge (Node.js, Supabase/Postgres)
- Comfort building UI flows (React)
- Passion for using AI not just as a tool, but as a core capability in product design
- Startup mentality: low ego, resourceful, and fast-paced
Preferred qualifications:
- Experience working with LiveKit or real-time communication platforms
- Exposure to LangChain, LlamaIndex, or similar agent frameworks
- Background in applied ML or RAG systems
- Product-minded engineer, understands the “why” behind features and contributes to UX/feature design
- Experience translating abstract AI capabilities into intuitive product workflows
