Responsibilities
Build and operate multi-agent systems that plan, coordinate, and execute tasks across multiple tools and services, to solve real user problems at scale
Implement agentic coding workflows, where agents generate code, run tests, create diffs or PRs, and iterate autonomously within guardrails
Design agent orchestration layers (planners, supervisors, evaluators) to manage task decomposition, retries, and long-running execution
Instrument and monitor agent behavior across success, failure, latency, cost, and human overrides, with exposure to agent-to-tool payment flows as the ecosystem evolves
Collaborate with Product & Design to translate user problems into shippable agent workflows, iterating quickly based on real-world feedback
Qualification
Required
Strong experience building LLM-powered systems in production, including prompt engineering, structured outputs, tool/function calling, and agentic coding workflows where agents write, modify, and validate code within guardrails
Solid backend engineering skills with Python and/or Node.js, designing APIs, async services, and background workers that support long-running, stateful agent workflows
Experience designing multi-step, agent-driven execution loops (plan → act → evaluate → retry), with explicit state management, idempotency, and failure recovery
Comfort with distributed systems primitives (queues, pub/sub, durable state, rate limiting, concurrency controls) required to coordinate agents at scale
Proven ability to instrument and observe agent behavior, emitting structured events for task success, failures, retries, overrides, and code-generation outcomes
Experience deploying and operating systems on cloud infrastructure (AWS or GCP), using Docker and CI/CD pipelines
Familiarity with inter-agent communication patterns, including message schemas, shared memory, blackboard systems, or event-driven coordination
Experience implementing agent evaluation pipelines (prompt regression tests, simulation-based evals, automated scoring, human-in-the-loop review)
Understanding of cost-aware execution for agents (dynamic model routing, caching, batching, budget constraints)
Experience with RAG architectures, vector databases, and persistent memory strategies
Exposure to emerging agent protocols (e.g., x402 payment flows, MCP), with the ability to implement evolving specs pragmatically
