Software Engineer, Developer Platform

About Glean: Glean is the Work AI platform that helps everyone work smarter with AI. What began as the industry’s most advanced enterprise search has evolved into a full‑scale Work AI ecosystem, powering intelligent Search, an AI Assistant, and scalable AI agents on one secure, open platform. With over 100 enterprise SaaS connectors, flexible LLM choice, and robust APIs, Glean gives organizations the infrastructure to govern, scale, and customize AI across their entire business—without vendor lock‑in or costly implementation cycles.

At its core, Glean is redefining how enterprises find, use, and act on knowledge. Its Enterprise Graph and Personal Knowledge Graph map the relationships between people, content, and activity, delivering deeply personalized, context‑aware responses for every employee. This foundation powers Glean’s agentic capabilities—AI agents that automate real work across teams by accessing the industry’s broadest range of data: enterprise and world, structured and unstructured, historical and real‑time.

The result: measurable business impact through faster onboarding, hours of productivity gained each week, and smarter, safer decisions at every level.

Recognized by Fast Company as one of the World’s Most Innovative Companies (Top 10, 2025), by CNBC’s Disruptor 50, Bloomberg’s AI Startups to Watch (2026), Forbes AI 50, and Gartner’s Tech Innovators in Agentic AI, Glean continues to accelerate its global impact. With customers across 50+ industries and 1,000+ employees in more than 25 countries, we’re helping the world’s largest organizations make every employee AI‑fluent, and turning the superintelligent enterprise from concept into reality.

If you’re excited to shape how the world works, you’ll help build systems used daily across Microsoft Teams, Zoom, Service Now, Zendesk, Git Hub, and many more—deeply embedded where people get things done. You’ll ship agentic capabilities on an open, extensible stack, with the craft and care required for enterprise trust, as we bring Work AI to every employee, in every company.

About the Role: Glean is seeking creative engineers to build the Developer Platform that external and internal developers rely on to extend Glean. Our team owns the developer experience end‑to‑end: standards and tooling for REST APIs, SDKs and client libraries, agent SDKs and integrations, and the infrastructure and docs that make it easy to build on Glean. In a rapidly growing startup, this means working across multiple layers of the stack – backend services, developer tools, SDKs, and docs – and partnering closely with product, security, SRE, and other engineering teams.

You’ll spend most of your time in Go, Python and Type Script building the foundations that power integrations, agents, and custom applications, while also helping define what “great” looks like for APIs and developer experience across Glean.

You will:

• Design, build, and evolve SDKs and client libraries that developers use to integrate with Glean from their own applications and agent frameworks.
• Own and advance agent‑focused tooling and SDKs (including MCP and related integrations) so external frameworks, IDEs, and agents can easily and reliably call into Glean.
• Define and maintain standards and conventions for Glean’s public REST APIs (resource design, versioning, errors, deprecations), and provide the OpenAPI schemas, tools, and CI checks that other teams use when building and evolving endpoints.
• Implement and harden platform and integration services in Go (and occasionally Java) that support developer workflows, agents, and external integrations, with a focus on reliability, observability, and debuggability.
• Build and improve developer tooling and automation that reduce “paper cuts” for external developers.
• Collaborate with security and SRE to design and operate authentication and authorization flows for developer scenarios (e.g., OAuth2/OIDC, dynamic client registration, service‑to‑service auth).
• Shape and improve the developer experience on  by contributing to documentation, quick starts, reference material, migration guides, and changelogs.
• Work closely with product managers, solutions engineers, and…
