Senior Product Manager, Platform

About the Role

This is the founding product management hire for Hiya's growth function. Our product portfolio spans B2B and B2C with distinct go-to-market motions, from product-led self-service to enterprise sales. As that portfolio has grown, so has the need for a consistent growth platform that every product team can operate on. We are in the early stages of building this platform, with a GTM engineer already in place and initial traction on the underlying infrastructure.

We are looking for someone to take ownership of the platform's product vision and scale it across the organization.

Your job is to build the growth platform that all product teams at Hiya use to run experimentation, measure funnels, and iterate on customer-facing surfaces. That means owning the experimentation framework, event tracking and instrumentation, the website platform (headless CMS), growth model dashboards, and lifecycle tooling. The platform is unified across the website and in-product surfaces, giving the whole company shared instrumentation and attribution through the full funnel.

You'll directly own the website and the platform itself; product teams continue to own what gets tested and shipped inside their products. You're also building the cross-functional operating model that ties demand generation, marketing, product, and sales together so that every product team works from a shared playbook with shared visibility into what's working.

This role requires senior, hands-on growth experience. You can't build a platform that serves working PMs without having done the work yourself. You'll partner closely with your GTM engineer, marketing, and demand generation leadership to execute. As the platform proves out, you'll have the case to grow the function.

• Own the growth platform strategy across experimentation, instrumentation, the website (headless CMS), growth model dashboards, and lifecycle tooling.

• Design the cross-functional operating model that connects demand generation, marketing, product, and sales into a coherent growth system with shared metrics and consistent process.

• Build a strong culture of experimentation at Hiya: define how experiments are structured, how results are measured and shared, and improve experimentation rigor and quality across all teams.

• Partner with product managers across Hiya's product lines to translate their growth needs into platform capabilities and shared tooling they can use independently.

• Bring a strong perspective on SEO and generative engine optimization (GEO) so the platform produces surfaces that perform well in both traditional search and AI-driven discovery, and partner with product marketing on content strategy execution, including multi-locale support.

• Establish operating rituals that keep the growth system healthy: experiment reviews, shared learnings, and regular alignment with marketing and demand generation.

• Use AI tools to accelerate platform development, analysis, prototyping, and the operational work of standing up a new function.

In this role, "builder" means taking ownership for turning a growth platform vision into systems that other teams actually use to ship.

That may mean:

• Prototyping experimentation tooling, instrumentation patterns, or platform capabilities yourself.

• Using AI tools to accelerate iteration and platform development.

• Running fast tests with product teams to validate whether new platform capabilities solve their real problems.

• Instrumenting the platform itself, studying how teams use it, and improving based on what you learn.

• Independently driving a platform initiative from concept to launch when scope and context make that possible.

• Helping product teams operate with more autonomy, curiosity, and speed.

We're looking for someone who can move fluidly between solo ownership and cross-functional collaboration, and who stays focused on what will create the most leverage for the teams operating on top of the platform.

• Product teams across Hiya are running growth work on a shared platform with consistent tooling and process, shipping faster and learning more effectively because of it.
