Lead Technical Product Manager, Platform

ABOUT POSH We are all social creatures, but the dominant “social” companies today have evolved into digital loneliness machines, driving isolation, anxiety, and mental health challenges around the world. Human connection is lost. Posh is a beacon guiding us back. Posh enables anyone to build an IRL community based on shared interests, while connecting consumers with the communities of people just like them. Founded by event organizers who were frustrated with the growing loneliness epidemic and the tools available to build their own event brand, we’ve built the ultimate platform for launching, monetizing, and finding IRL communities of people just like you. In just 6 years, Posh has grown to a team of 70, expanded to 8M+ users, secured $70m in venture funding, and facilitated over $350M in transactions. ABOUT THE ROLE Startups are defined by their feature set. Generational platforms are defined by their reliability. As the team scales toward 40 engineers by EOY and the platform scales past 10m users, powering events with up to 20k attendees, our infrastructure is rapidly becoming one of the most important determinants of our success. As our founding Technical Product Manager, you'll partner directly with our CEO, Product Team, Director of Engineering, and a team of Senior and Staff Engineers to shape the roadmap, architect the team, and own execution of our most complex technical problems with one goal in mind: make Posh the most scalable and reliable events platform to ever exist. Your work will span across 2 core teams: - Platform: Owning observability/incident response, backend services, notifications, authentication/permission systems, localization, and experimentation infrastructure to optimize reliability and empower user-facing teams to create novel technical innovations - Internal Operations: blurring the lines between product, GTM, marketing, and operations to empower teams with software tooling that accelerates their goals This role reports to the CEO, working in lockstep with the entire leadership team to ruthlessly prioritize projects, allocate resources, and accelerate velocity. This is an in-person position at our SoHo NYC office, 5 days a week. WHAT YOU'LL OWN & ACHIEVE - Own infrastructure end-to-end: Turn company objectives into an actionable roadmap, defining, tracking, and improving key reliability metrics to establish the infrastructure necessary to support hundreds of millions of users. Free our engineers from the planning work they currently absorb so they can focus on building. - Be the technical translator between Platform and the rest of the company: Collaborate at the intersection of deeply technical backend engineers and non-technical stakeholders to prioritize engineering needs & limitations against company objectives, scope & milestone robust projects, and communicate the importance of technical decisions to the broader organization. - Run incident response as a first-class program: Own on-call rituals, observability, and post-mortems to ensure best-in-class SLAs and SLOs. Make sure every meaningful incident becomes a durable improvement in reliability or developer experience. - Drive build-vs-buy decisions: Lead the evaluation of where to invest in homegrown tools vs. third-party integrations, balancing cost, effort, and long-term leverage. - Make Platform's impact legible: Establish the dashboards and rituals that prove Platform improvements are making Posh more reliable while improving developer experience. - Partner on architecture, not just timelines: You won't be the architect, but you should be deep enough in the system to push back on scope, identify hidden complexity, surface tradeoffs to leadership, and earn the trust of our Staff engineers in technical conversations. Engineers should treat you as a peer in the design phase, not a project manager who shows up after the decisions are made. - Scale the Platform operating model: As your team grows into two clear sub-pods (Product Infrastruct
