Addepar, Inc.; Mountain View (CA); On-site; USD 163,000 - 204,000; Full time

Job summary

Addepar, Inc. is seeking an Applied AI Engineer to build agentic AI systems for strategic clients. You will understand client workflows, prototype rapid solutions, and partner with core engineering to ship features that scale across customers.

You will design LLM integrations, implement tool interfaces, and develop evaluation harnesses while collaborating with clients to validate AI behavior and production-readiness.

Qualifications

• 2+ years of professional software engineering experience.
• Experience with Python as primary language.
• Experience with LLM APIs including function calling and structured outputs.
• Comfort with SQL for data exploration and building data-grounded AI workflows.
• Experience with AI-assisted development tools (Claude Code, Codex, or similar).

• Bias for action and rapid iteration.
• Bachelor's or Master's in CS, Mathematics, or quantitative field, or equivalent experience.

Responsibilities

• Build AI-powered agents and tools end-to-end: identify client problems, prototype quickly, evaluate rigorously, and ship to production.
• Design and implement LLM integrations including prompt engineering, function calling, structured outputs, and retrieval-augmented workflows
• Define evaluation criteria and build test harnesses for AI systems where correctness is ambiguous and domain-specific
• Work directly with clients to understand workflows, validate AI behavior, and iterate toward production quality
• Partner with core engineering teams to generalize client-specific work into product features
• Contribute to shared AI infrastructure (agent frameworks, tool integrations, deployment pipelines)
• Monitor and maintain production AI systems with attention to reliability, cost, and performance
