Sr. Product Manager - Partnerships; Yahoo Mail

Yahoo Mail is the ultimate consumer inbox with hundreds of millions of users. It's the best way to access your email and stay organized from a computer, phone or tablet. With its beautiful design and lightning fast speed, Yahoo Mail makes reading, organizing, and sending emails easier than ever.

Yahoo Mail is one of the world's largest consumer email platforms, serving hundreds of millions of users globally across web, iOS, Android, and other client surfaces.

Beyond serving individual users, Yahoo Mail is a trusted platform for a diverse ecosystem of partners. Some are large enterprises and consumer brands who rely on Yahoo Mail to deliver and operate email experiences for their own customers at global scale. Others consume specific Yahoo Mail APIs, capabilities, or services, including emerging access patterns such as MCP, to enrich their own products and increasingly their AI agents.

Still others are platform customers who build on top of our infrastructure in more targeted ways. Across all of these models, our partner ecosystem is central to how Yahoo Mail extends its reach and value, and managing those relationships well, including protecting the integrity of our platform from abuse, is critical to the long‑term health of the product and the business.

We are looking for a senior product manager, partnerships, to lead the product strategy and execution for Yahoo Mail’s external partnerships and partner integration program. This role owns the relationships, product surfaces, and integration capabilities that serve our full partner ecosystem. That includes large‑scale partners who operate Yahoo Mail experiences for their own customers, partners who consume our APIs, MCP endpoints, and capabilities to enhance their own products and AI agents, platform customers who build on top of our infrastructure, and the broader program enabling industry partners and developers to integrate with Mail.

This is a senior, highly cross‑functional role that works deeply with experience‑focused product managers, client and platform engineering teams, business development, legal, and central trust and safety teams. You will be responsible for ensuring that partner integrations are secure, reliable, and commercially aligned, while remaining adaptable as the Yahoo Mail product and platform evolve.

A critical dimension of this role is acting as the connective tissue between external partners and Yahoo Mail’s internal product and engineering organization. You will translate partner needs into product direction, advocate for partner requirements where they align with our strategy, and shape the integration patterns and tooling that make our partner program scalable. This work requires strong commercial judgement, excellent stakeholder management, and comfort operating in environments where product, business, and contractual considerations intersect.

Equally critical is deep technical understanding. This is not about expertise in any single technology. It is about the ability to translate partner and business requirements into technical requirements, to understand how Yahoo Mail’s platform works at a system level, and to reason in both directions about how our platform shapes what is feasible for partners and how partner requirements should influence the platform.

The right person will be able to sit in a room with engineering and confidently discuss tradeoffs, identify where a partner ask creates friction with our architecture, and recognize when a small platform change unlocks meaningful partner value.

Trust and abuse prevention are inseparable from this work. Every partner integration, whether a hosted experience, a traditional API, or an MCP endpoint consumed by an AI agent, is a potential vector for abuse if not designed thoughtfully. APIs can be abused, credentials can be misused, and agent‑driven access introduces new categories of risk including prompt injection, agent‑to‑agent abuse, and large‑scale automated misuse on behalf of users.

The person in this role is expected to treat anti‑abuse as a first‑class product concern, working closely with trust and safety, security, and engineering to ensure…
