Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way. The Community You Will Join: Airbnb is a vision and mission driven company, and our Product Managers embody that mindset. Platform PMs imagine the ideal end state for our community first, work backwards from it, and deliver it in a scalable way. The AI Assistant team owns the agentic AI system that powers Airbnb's support experience for millions of guests and hosts. This is one of the highest-visibility applied-AI efforts at the company, and it sits at the intersection of large language models, platform thinking, and a genuinely two-sided marketplace. The Difference You Will Make: You will own the platform that determines how our AI Assistant reasons, retrieves, and responds: the layer that interprets each request and routes it, the knowledge and capabilities the assistant draws on, the actions it can take to actually resolve an issue, and the evaluation systems that keep it safe and accurate at scale. You will own what a good outcome looks like for the user, and the criteria we measure it against, working through partners who own the underlying knowledge and the engineering implementation. This is a role where Product both directs technical work and does it themselves. You will diagnose architectural problems, author the artifacts that become production behavior, and help drive engineering and data science decisions alongside your key partners. Support is high-stakes: people reach out when something has gone wrong, often with another party involved. You will be responsible for making those moments accurate, safe, and genuinely helpful, increasing how often the assistant fully and correctly resolves

At Datadog, we're on a mission to build the best platform in the world for engineers to understand and scale their systems, applications, and teams. We operate at high scale, enabling seamless collaboration and problem-solving among Dev, Ops, and Security teams globally for tens of thousands of companies. Our engineering culture values pragmatism, honesty, and simplicity to solve hard problems the right way. Feature flags used to be simple on/off switches. That's changing fast.

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. This is not a back-office compliance role and it is not a generic sales-engineering role. You will operate as a named member of deal teams under our pod model: paired with Strategic and Enterprise Account Executives, embedded in their weekly cadences, engaged from first discovery through POC, onsite, close, and expansion. You will be the practitioner in the room that a buyer's CISO or GRC lead trusts — and the internal expert our AEs, SEs, and marketing team build around. What you’ll do as a Subject Matter Expert at Vanta: Serve as the dedicated GRC SME for a book of Strategic/Enterprise Account Executives: join discovery and qualification calls at the earliest deal stages, scope compliance programs against Vanta's platform, and support demos, POCs, workshops, and customer onsites across Compliance, Third-Party Risk Management, Risk Management, and Trust/Questionnaire Automation.

Answer field questions through our SME channels at customer-forwardable quality — including reviewing and validating AI-agent-generated answers before they reach customers. Our team runs AI-first: you'll use agents daily, act as the quality gate on their output, and (ideally) build tooling of your own. Design and deliver enablement: live sessions for GTM teams, bootcamp scenarios and mock-customer roleplay, async curriculum modules, and review of GRC marketing and SEO content. Own monthly alignment cadences with sales front-line managers; feed structured product feedback to our Product and PM
