• 2+ yrs shipping production software, incl. any experience building with LLMs (OpenAI, Claude, etc.) or non-LLM ML engineering
• Can design and measure agent workflows: prompt chaining, RAG, vector stores, guardrails, eval suites

• Willing to work in-person in Singapore, and you’re serious about building a culture we’ll all love
