Glean•Mountain View, CA

About The Position

Glean is seeking a Product Manager for its API Platform to lead the development of Glean's APIs, SDKs, and MCP strategy, targeting developers within customer organizations and partner companies. This role requires a strong technical background, a deep understanding of developer needs, and a passion for building robust, scalable API and SDK solutions. The Product Manager will also collaborate with leading B2B product companies for the partnership strategy. The position involves owning the design and evolution of public APIs and SDKs, including versioning, deprecation, and backward-compatibility. A key aspect is defining the end-to-end developer experience, covering authentication, onboarding, first call, error handling, rate limiting, webhooks, and edge cases. The role also includes writing code, building sample applications, running integrations, and proactively identifying and fixing issues based on customer feedback and support tickets. Success will be measured by key metrics such as time-to-first-call, integration success rate, and API error rates. The Product Manager will be responsible for locking API contracts and requirements before engineering begins development and managing scope creep.

Requirements

5+ years of product management experience, ideally in platform, developer experience, API, SDK, or partnership-driven products
Deeply technical and comfortable working through API contracts, request payloads, logs, telemetry, and implementation tradeoffs with engineers
Built or led APIs and SDKs that are robust, scalable, and easy for external developers to adopt
Strong product taste for developer interfaces and care about clear abstractions, consistent resource design, and machine-readable errors
Know how to think from the developer’s point of view and can quickly spot where documentation, workflows, or product behavior become confusing
Worked directly with customer and partner developers and know how to translate their needs into better platform products
Experience integrating products with third-party enterprise applications and understand what it takes to make those integrations reliable in production
Write clearly and value concise specs, accurate documentation, and product experiences that tell developers what to do next
Define success with metrics and can track adoption, usability, and business impact for developer-facing products
Excited about AI and motivated by helping customers and partners build more effectively with it

Responsibilities

Own the design and evolution of our public APIs and SDKs, including versioning, deprecation, and the backwards-compatibility promises we make.
Spec the developer experience end to end: auth, onboarding, first call, error handling, rate limiting, webhooks, and the long tail of edge cases that decide whether someone stays.
Write code. Build the sample apps, run the integrations, and feel the rough edges yourself before a customer does.
Read the docs like a developer who's never seen them, then fix the parts that lie or leave things out.
Dig into support tickets and forum threads for patterns. Treat a recurring question as a design defect, not a documentation gap to paper over.
Set and defend the metrics that matter: time-to-first-call, integration success rate, API error rates, and the ones that actually predict whether a developer ships.
Lock the API contract and requirements before engineering starts building, and hold the line when someone wants to bolt on scope mid-flight.
