• Minimum of 2 years of experience in developing ML data pipelines
• Experience with text embeddings, RAG systems, and similarity search
• Familiar with Entity and Relationship recognition models
• Skilled at prompt engineering
• Ability to implement backend systems in Python and/or Node.js
• You can evaluate tradeoffs and propose the most appropriate storage solution (SQL, NoSQL, Vector DBs, Graph databases)
• You enjoy hard problems and open-ended assignments
• You use data to make decisions, and experiment your way around hard problems

Bonus points:

• You've developed products with LLMs before (extra if you've already built your own agents)
• You have fine-tuned foundational models to tailor responses to specific data use cases
• You have experience with LlamaIndex and Memgraph to produce knowledge graphs

Perks and benefits:

• Generous equity package
• Competitive salary and benefits
• 401(k) retirement account
• The best equipment and tools, like a spec'd out MacBook, and dev prod tools like Cursor, Claude, and Linear to help you move fast
• Flexible work arrangements with in-office work or hybrid/remote work for the right candidate
• Our current office is in San Mateo, just steps from Caltrain
