Senior Product Manager, Growth Platform

About Hiya

At Hiya, we're making calls safe, useful, and human again. Voice is the most human form of communication, yet it's become one of the least trusted. Spam, scams, and AI manipulation have eroded what was once a simple way to connect. Each month our AI voice technology analyzes 28+ billion calls, protecting over 550 million users and 800+ businesses worldwide. Partnering with a growing global network including, AT&T, Samsung, British Telecom EE, Rogers, MasOrange, Bell Canada, MasMovil, and Virgin Media O2, we're not just stopping bad actors, we're helping people feel good and confident about picking up the phone again. This is a pivotal moment for voice. As new threats and technologies accelerate, so does demand for trusted voice communication. Hiya is growing 40%+ year over year, expanding globally, and defining what voice becomes next. Join us. You won't just work on what voice is today, you'll shape what it becomes tomorrow: smarter, safer, and genuinely worth answering again.

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're 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.

What You'll Do

• 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 mult-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

What "Builder" Means in This Role

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.

What Success Looks Like

• 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

• The cross-functional operating model between demand generation, marketing, product, and sales is defined, functioning, and producing shared visibility into what's working across the funnel

• Marketing retains clear governance over brand and narrative, while product teams have the autonomy and tooling to iterate quickly on the surfaces they own

• Within six months, the platform and operating model are producing measurable improvements in experimentation velocity and cross-functional alignment, with early indicators of revenue impact driven by a strong LTV/CAC ratio on self-serve product lines

What You'll Need to Succeed

Required

• Demonstrated success in growth, including hands-on work building activation funnels, running experimentation programs, and connecting acquisition through conversion through expansion in self-serve acquisition motions

• Experience building growth platforms, tooling, or infrastructure that other teams operated on: experimentation frameworks, A/B testing and feature flag systems, analytics and event tracking platforms, CMS platforms, or cross-functional operating models

• A track record of improving experimentation rigor and quality across multiple teams, not just within a single team

• Expertise in SEO and emerging GEO practices, with informed opinions on how platform and CMS decisions affect organic discoverability

• Proficiency with AI tools as a core part of how you work, with hands-on experience using them to accelerate analysis, prototyping, and platform development

• Data fluency for defining leading metrics, building shared dashboards, and creating the feedback loops that make experimentation programs learn

• The ability to build trust with product managers who own their own growth goals, positioning yourself as an enabler of their work rather than a competitor for their scope

• A high-agency, builder-oriented approach: you create structure in ambiguous situations and take ownership for outcomes

• Strong communication skills and the ability to translate between growth, marketing, product, and engineering contexts fluently

• Alignment with Hiya's values: serving our customers, doing rather than observing, improving ourselves and our business, owning and holding ourselves accountable for success, leading with a point of view, engaging in open discussion, and committing to decisions

Preferred

• Experience as a founding or early growth hire, building the function and the playbook rather than inheriting them

• Hands-on experience with headless CMS platforms, particularly Contentful or Payload, including content modeling and multi-locale support

• Experience with modern analytics and instrumentation stacks (Segment, Amplitude, Mixpanel, GA4) and tag management

• Familiarity with experimentation platforms (Optimizely, Statsig, or equivalent), including evaluation tradeoffs between build, buy, and open-source options

• Familiarity with marketing automation and lifecycle tooling (HubSpot, Braze, Iterable, Customer.io )

• Experience in environments where multiple product lines with different go-to-market
