Full Job Description

đź“‹ Description

  • • Design and ship production multi-agent systems that automate go-to-market workflows, including agent control loops, planning, orchestration graphs, and tool-integration layers
  • • Build and maintain the safe write-back path that applies agent decisions to customers’ live data systems without risk of data corruption or inconsistency
  • • Develop evaluation frameworks with custom test cases, rubrics, and regression tests to measure agent performance and prove improvements from system changes
  • • Design agent memory systems including persistent per-account context, pre-computed state, and just-in-time retrieval mechanisms to ensure fast, cheap, and reliable reasoning across thousands of concurrent agent instances
  • • Harden agent systems against adversarial inputs such as malformed account names or maliciously crafted notes that could hijack agent behavior or decision logic
  • • Integrate frontier large language models behind a model-agnostic abstraction layer, routing tasks by cost, latency, and performance requirements while owning the reliability and cost efficiency of the agent surface
  • • Create reusable patterns and abstractions that accelerate the team’s ability to build new agents while maintaining consistency, safety, and observability
  • • Own end-to-end delivery of agent systems from concept to production, including debugging deep, non-deterministic failures in multi-step agent traces
  • • Collaborate with cross-functional teams to align agent capabilities with go-to-market business objectives and customer data requirements
  • • Maintain high standards for system durability, concurrency, and distributed systems design under enterprise-scale loads
  • • Ensure multi-tenant data isolation and a strong security posture when handling sensitive customer data within agent memory and execution environments
  • • Continuously optimize for latency, cost, and reliability across agent operations, balancing performance with economic efficiency at scale
  • • Document system architecture, failure modes, and operational procedures to enable team scalability and knowledge sharing

🎯 Requirements

  • • 4+ years building production systems, including 2+ years shipping LLM-powered or agentic systems
  • • 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
  • • Strong, current Python (TypeScript or Go a plus)
  • • Hands-on with a modern agent framework / orchestration (e.g. LangGraph or agent SDKs), tool/function-calling, structured outputs, retrieval (RAG), and context/memory management
  • • 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
  • • High agency: you scope, prioritize, and ship without waiting for permission

🏖️ Benefits

  • • Salary between $160,000 and $200,000 base, plus equity
  • • Office-based role requiring in-office presence on Mondays and Wednesdays each week
  • • Work at the core of LeanData’s new autonomous agents platform for go-to-market teams
  • • Opportunity to own founding-level systems with direct impact on enterprise revenue automation
