About the role
- LeanData helps the world's fastest-growing companies automate, simplify, and accelerate revenue.
- This is a Staff-level individual-contributor role with founding-level ownership.
- This role reports to the SVP of Engineering and is based in our Santa Clara, CA office.
Responsibilities
- Build and ship production multi-agent systems end to end: agent control loops and planning, the orchestration graphs and tools they call, and the coordination, handoffs, state, and durability across agents
- Build the safe write-back path that applies agent decisions to a customer's live systems without corrupting data
- Evaluate everything you ship: build the eval cases, rubrics, and regression tests that prove a change made the agent better
- Design agent memory and retrieval: persistent per-account context, pre-compute, and just-in-time lookups that keep reasoning fast, cheap, and reliable across many concurrent agent instances
- Integrate frontier LLMs behind a model-agnostic abstraction with routing by task, cost, and latency; own the cost, latency, and reliability of your surface, and create the patterns that let the team build agents faster
- build the eval cases, rubrics, and regression tests that prove a change made the agent better
Requirements
- You have shipped customer-facing LLM or agent systems that real users depend on, and can explain how they failed and how you fixed them
- Experience with Salesforce APIs (Bulk 2.0, Composite, Pub/Sub) or another large, messy enterprise data source
- You are required to be in office Mondays and Wednesdays each week.
Nice to have
- Strong, current Python (TypeScript or Go a plus)
- Strong systems-engineering fundamentals (concurrency, distributed systems, statefulness, latency and cost at scale), plus skill debugging deep, non-deterministic failures in multi-step agent traces
Compensation
- The salary for this role will be between $160,000 and $200,000 base, plus equity.
