Lead AI Product Engineer - AI Agents & Emerging Products

What You’ll Do:

• 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.

What You’ll Bring:

• 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.

Who You Are:

• You operate with high urgency agency and a bias for action translating ideas into working systems quickly learning from real-world signals and iterating continuously.
• You pair speed with rigor bringing strong engineering fundamentals (systems thinking evaluation discipline reliability) so each iteration is meaningfully better not just different.
• You embrace a “long is wrong” mindset simplifying automating and removing bottlenecks to consistently reduce cycle time.
• You think and act like an owner making sound tradeoffs and taking end-to-end accountability for performance reliability cost and user experience.
• You optimize for technological leverage building reusable primitives tooling and patterns that compound team output over time.
• You are growth-minded working backward from LTV/CAC and prioritizing engineering work that moves activation retention conversion and cost per successful outcome.
• You excel at constraint removal unblocking execution and increasing innovation per unit time including through agentic tool use with clear guardrails and observability.
