You’ll help define a new product area, partnering with **product, design, and engineering** to discover customer needs and deliver practical solutions.

Distinguish recommendations from actions that commit customer spend. - Make cross-platform workflows reliable with durable state, idempotency, safe retries, reconciliation, observability, and recovery from partial failures, expired credentials, rate limits, and provider API changes. - Establish agent evaluations and production monitoring for plan quality, tool selection, policy compliance, spend safety, and verified execution. Partner on experiments that distinguish attributed results from incremental customer value. - Lead ambiguous initiatives across product, design, AI, data, security, and partnerships—staying hands-on with implementation, defining incremental milestones, mentoring engineers, and owning quality and operations. ## Required Skills & Experience - Track record of **Staff-level technical leadership** on complex customer-facing products/platforms: setting direction, resolving ambiguity, and delivering through launch and production operation across multiple teams. - Strong hands-on software engineering and system design across **APIs, data modeling, distributed systems, asynchronous workflows**, and customer-facing product experiences. - Experience building and operating **third-party integrations** that remain correct under duplicate requests, partial failures, rate limits
