About The Position

Poseidon is building the data infrastructure that the next generation of AI will depend on. Foundation models aren't bottlenecked by compute; they're bottlenecked by rare, high-quality, IP-safe data that actually improves performance. In the AI era, data is the new form of intellectual property. The datasets that power models are the assets that create lasting value. Poseidon connects AI companies with the data they need, enabling scalable, compliant, demand-driven data sourcing. Backed by a16z, the team is early, moving fast, and focused on defining this new category. Examples of the datasets we work with include conversational audio, complex video, domain-specific imagery, and other real-world data that enables models to perform reliably outside controlled environments. Numo is an app we built that is part of this ecosystem. Numo is a consumer application that lets people around the world contribute training data through simple tasks and get rewarded for it. We're currently focused on voice data across underrepresented languages, building a scalable, distributed supply layer for high-quality AI training data, and we will expand to more tasks and modalities in the near future. We've launched the first version of Numo as a web app. Now we're building the native mobile experience from scratch (iOS and Android), and we need someone to own it end-to-end and scale it to millions of users. This is a senior product role. You'll be the loudest product voice in the room, partnering directly with engineering leadership to drive the product process and hold the line on the decisions that matter. You're not maintaining a roadmap someone else wrote. You're shaping the product from the first wireframe through launch and into growth. You'll take what exists today and decide what carries over, what gets rebuilt, and what needs to be invented for mobile. You'll own what gets built, how it feels to use, and whether the numbers move. The first version is shipped. The hard part, getting from one to ten million users, is the job.

Requirements

• Experienced mobile PM with a very strong backbone
• Track record that includes scaling a consumer mobile app from early traction to millions of users
• Experience knowing what breaks at 100k, at 1M, and at 10M, and have been the PM in the room when it broke
• Strong growth instincts
• Understanding of performance marketing channels (Meta, TikTok, Google) well enough to know how product decisions affect CAC and payback
• Thinking in terms of Day 1, Day 7, and Day 30 retention and knowing what good looks like
• Real product authority: comfortable holding the line on product decisions in a fast-moving engineering culture
• Ability to push back, drive alignment, and run the process without being overridden
• Strong design sense
• Familiar with HIG and Material Design at a level where you can hold your own with designers or lead design directly
• Obsession over finer details, even if AI drafts it
• Comfortable with data: building your own dashboards and not waiting for a data team to answer basic questions

Nice To Haves

• Consumer mobile apps with proven viral growth (recent breakouts in AI, social, fitness, gaming)
• Mobile gaming, sports betting, or any product built on engagement mechanics and habit loops
• AI labs or data-collection companies (Scale, Mercor, Surge and similar), particularly anyone who has built systems for large-scale data contribution

Responsibilities

• Define product vision, strategy, and roadmap for the mobile apps
• Translate an early web product into a best-in-class mobile experience
• Drive product process end-to-end, partnering closely with engineering and design leadership
• Own the full user funnel: onboarding, activation, retention. Find the drop-offs, run the tests, fix the leaks
• Engineer growth into the product from day one through ASO, referral loops, deep linking, and viral mechanics
• Set up and run the analytics stack (Amplitude, Mixpanel, AppsFlyer, or similar) and use it to make decisions
• Work directly with the design team on a product that has to feel as good as the best consumer apps people use every day

Benefits

• This is a founding role with real ownership over the product that matters most to the company right now
• You're not inheriting a mobile app. You're building it from scratch and making it work
• The infrastructure layer (Poseidon, a16z-backed) gives this consumer product a moat most consumer apps don't have
• If you want to build something from nothing and scale it to real impact, this is that job
• We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
