Strong Signal: Not dealbreakers, but what separates a good hire from a great one. * Experience running structured experiments or A/B tests to improve a product metric, not just intuition-led changes. * Technical fluency: you can scope webhook systems, OAuth flows, and complex integrations yourself. * Customer confidence: you thrive talking with customers, running demos, and co-selling alongside sales. Nice to Have: Bonus, not required. * Experience building trust or visibility features (dashboards, coverage reporting, status pages) for a product customers rely on. * Background implementing or rolling out complex systems for enterprise customers. ## Description Siena is the Agent of Record for CX, built for consumer brands like Spanx, FIGS, Brooklinen, and Grüns. It runs as a connected multi-agent stack on top of a shared intelligence layer: agents that sell, support, listen, handle social and voice across the entire customer journey, turning every conversation into signal you can act on. The team We are a small, fully distributed, global team. We have built leverage into how we work, which is what lets a team this size move at the speed we do. We hire athletes. Everyone here owns real outcomes, defaults to writing over meetings, communicates with directness, and acts the moment they see something worth acting on. Low ego, high standards, fast clock. If you want to set the bar rather than follow one, keep reading., Siena needs a PM to own the core of our agent platform, the systems that decide what our agents can do, how well they perform, and how customers can see that performance for themselves. You'll set the roadmap for where the platform's capabilities expand next, build the measurement and testing that make it better over time, and make sure customers always have clear, real visibility into what's happening. You're a strong problem solver first, and you've been a Product Manager in CX, ecommerce, helpdesk, or AI automation., * Build and ship the evaluation, testing, and monitoring systems that make agent performance measurably better over time. * Give customers real-time visibility into what the platform is doing and why, so trust compounds. * Design and run journey-level A/B tests across agent flows, and use the results to decide what ships next. * Own onboarding so customers reach full platform value quickly, own onboarding and keep compressing the path to full platform value. * Run full launch cycles for platform features: internal testing, early access, GA, with customer enablement through webinars, docs, and training. * Demo platform wins to customers directly and co-sell alongside sales. * Work forward deployed: sit with customers, scope live, ship the improvement.
