About Runlayer

AI is transforming how every company operates, but most enterprises are stuck. They want to move fast with AI Agents, tools, and workflows, but they can't do it safely. We're fixing that.

Our team built AI Actions for OpenAI, shipped Zapier Agents to millions of users, and launched the first remote MCP server with Anthropic. We helped establish the protocol, and now we're building the platform enterprises need to actually put MCP to work.

Runlayer is one platform for MCPs, Skills, and Agents: purpose-built security, fine-grained governance, and complete observability so organizations can go all-in on AI across the entire company without the risk. We just raised a $30M Series A led by Felicis, with participation from Khosla Ventures, bringing our total raised to $42M. Already trusted by Gusto, Instacart, Opendoor, dbt Labs, Cursor, and Decagon.

We're a team of 35, mostly engineers, shipping fast. Agent operators on Runlayer grew 5x in four weeks while human operators stayed flat. The shift to agentic work is already showing up in our own usage.

About the Role

As an Identity engineer, you'll own the authentication and authorization layer that secures every AI-to-enterprise connection on Runlayer, from the OAuth broker behind our enterprise integrations to how AI agents prove who they are and get auditable access. You'll work directly with customers and help shape the MCP Auth spec that defines how agent identity works industry-wide.

Why You'll Thrive Here

• Impact: Own the identity and authentication layer that secures every AI-to-enterprise connection on our platform.

• Excellence: Work alongside engineers who've shipped AI systems at scale.

• Ownership: Shape how MCP & AI agent authentication works, from spec-level decisions to production code.

What You'll Do

• Architect and implement authentication and authorization systems for MCP servers (OAuth 2.0, Dynamic Client Registration, token management).

• Build and extend our OAuth broker that handles enterprise identity integrations across dozens of vendors.

• Design identity propagation for AI agents, ensuring secure, auditable access to enterprise systems.

• Integrate with enterprise identity providers (Okta, WorkOS, Azure AD) and SCIM systems.

• Define fine-grained access control policies for MCP tools and resources.

• Collaborate directly with customers like Gusto and Rippling to solve real-world identity challenges.

• Contribute to the MCP Auth spec and help define how agent identity works industry-wide.

What We're Looking For

• 5+ years of software engineering experience with significant focus on identity, authentication, or authorization systems.

• Deep experience with OAuth 2.0/OIDC, including DCR, token exchange, and audience restriction.

• Background building or integrating with enterprise identity systems (Okta, WorkOS, Auth0, AWS IAM, GCP IAM).

• Strong fundamentals in distributed systems and API security.

• Experience with Python and TypeScript (our stack is Python/FastAPI backend, TypeScript/React frontend).

• Comfortable working directly with enterprise customers to understand and solve their security requirements.

• Heavy AI user who leverages tools like Claude Code or Cursor to multiply output.

Bonus Qualifications

• Experience with Kubernetes-native authorization patterns or service mesh security.

• Background in ML security (differential privacy, LLM security research).

• Prior work on identity for multi-tenant SaaS platforms.

• Familiarity with the MCP specification.
