Why Join Us? Keet is a fully peer-to-peer messaging and video calling app built on Holepunch's P2P stack. There are no servers, no middlemen, and no data harvesting. People talk directly to each other, with end-to-end encryption by design. We're taking Keet to a billion users, competing head-on with WhatsApp and Telegram. Product sets the direction. We're looking for a Product Engineering Lead to turn that direction into features people love, built to a standard that holds up at global scale. You lead the teams that build Keet's features: the API team, which adds feature-focused APIs to Keet's core, and the frontend team, which builds the React app on top, each with its own lead. You report directly to the CTO and take direction from product. Product owns the what and the why. You own the how and the engineering bar. The split is roughly 70% engineering leadership and 30% product. You're a combination of three things. You're an engineering leader who has helped teams ship consumer products at speed. You have real product sense and can partner with PMs as an equal, shaping what gets built, not just executing it. And you have an intuition for distributed, local-first systems, so you can work fluently on top of a P2P engine without needing to build it yourself. Responsabilities Engineering Run the API and frontend teams day to day: unblocking, reviewing, and keeping them shipping. Set and hold a high engineering bar for performance, reliability, and clean APIs. Own the technical design of features and the API surface between Keet's core and the app. Make sure the API team works closely with our deep tech teams on code reviews, design, and anything that touches the engine. Product Partnership Work alongside Keet's product managers to turn vision and roadmap into scoped, buildable work. Push back when scope and reality don't match, and propose better paths when they exist. Bring an engineering perspective to product decisions, especially where P2P opens doors that centralized apps can't. Help the team move fast, using AI tools and quick prototypes to validate ideas before committing to them. Leadership Create clarity around team goals and make sure everyone knows what success looks like. Mentor team leads to build strong team operating systems, improve how their teams work with others, and grow as leaders. Lead by example: roll up your sleeves when the team needs it, and step back when they're ready to own it. Experience managing engineers or engineering leads who ship consumer product, ideally in chat, calling, or social apps. Strong product sense: you can tell a good feature from a busy one. Intuition for distributed and local-first systems. Offline-first and eventual consistency should feel natural. You don't need P2P protocol expertise, because our core abstracts it away. Deep JavaScript and React. Initiative, curiosity, resilience, and the ability to give and receive direct critique. Bonus: experience with local-first apps, CRDTs or sync engines, offline-capable mobile or desktop apps, or open source.

We build native Swift and Kotlin SDKs optimized for ms initialization and minimal binary overhead, with Unity, Flutter, and React Native wrappers that provide a unified API across the entire mobile ecosystem. Behind the scenes, a high-throughput Go and DynamoDB architecture handles the real-time state synchronization of millions of concurrent sessions. When your code runs on nearly one out of every seven smartphones on Earth, every millisecond of execution and every byte of memory counts. What you Will Do: - Own and prioritize the Mobile SDK product backlog, balancing customer needs, business priorities, technical requirements, and engineering capacity. - Translate product and developer needs into clear requirements, user stories, acceptance criteria, and actionable priorities for the engineering team. - Drive feature delivery from discovery and planning through development, testing, release, and post-launch evaluation. - Work closely with Android, iOS, Backend, QA, and other stakeholders to manage dependencies, resolve blockers, and ensure smooth delivery. - Gather and analyze feedback from customers, developers, and internal teams to identify integration pain points and opportunities to improve the SDK and developer experience. - Support SDK releases and rollouts, including release planning, documentation, adoption tracking, and communication with relevant stakeholders. - Use product data, SDK telemetry, and feedback to measure outcomes, identify opportunities, and continuously improve the Mobile SDK platform. Who You Are: - You bring 3+ years of hands-on experience as a Product Owner in a fast-paced, high-growth environment. (Bonus points if you have a background in ad-tech or Mobile/SDKs) - You aren't expected to write code, but you are right at home discussing SDK architecture. You grasp the fundamentals and differences between iOS and Android, empowering you to have meaningful debates with the development team and properly weigh technical debt against business value. - You have a proven track record of leveraging A/B testing and experimentation to drive product strategy. You know exactly how to define clear success metrics, analyze KPIs, and confidently pivot based on what the data tells you. - You are a digital native who speaks the language of both business and engineering fluidly. You excel at closing the gap, aligning what the business envisions with what the technology can actually execute. - You take deep ownership of your product. You are comfortable navigating ambiguity, working independently, and making the objective calls needed to balance incoming business requests with the long-term technical integrity of the platform. - You possess concise, direct communication skills. You know how to align, motivate, and guide interdisciplinary teams, cultivating a thriving and collaborative environment even as project requirements evolve.
