About The Position

MintMCP helps companies put agents to work safely. We exist to help companies do more of their work with agents, and we build the infrastructure that makes a company's own work runnable by them. Our first product is an MCP gateway that gives those agents governed access to company data and tools. Before agents can touch Slack, GitHub, Jira, Snowflake, internal databases, or production systems, you need to know what they can reach, what they did, and why they were allowed to do it. MintMCP scopes that access down to exactly what an agent needs to do its job and captures the data flows and audit logs security teams need. From there we are building the rest of the agent stack: connectors, monitoring, sandboxing, long-running agents, and memory, with the goal of becoming the system a company's work runs on. We work in person in the San Francisco Bay Area. The structure is flat and the market moves fast, so you have a lot of latitude over what you work on and how. We are AI-native. Everyone uses Claude and Codex every day, and we have more agents than employees. They run in Slack alongside the team, write code, review PRs, and handle sales, marketing, and deal ops on the same gateway we sell to customers. We are building an entire company operating system around them, and you will help build it. Since launching in February 2026, we have grown to 40+ paying customers, with strong inbound demand. Customers include Coursera, Arlo, and Braze. We are backed by Cowboy Ventures and Coatue, with angels including Frederic Kerrest (Okta), Michael Grinich (WorkOS), Andrej Karpathy, Jeff Dean, and Scott Belsky. Our founders are machine learning experts from Stanford, Berkeley, and CMU, with applied research at Google Brain and Waymo, and one co-founded Coursera.

Requirements

• A builder with a track record of shipping to real users, whether that is a product, an internal tool, an open-source project, or a serious side project.
• Ship, then iterate, without waiting for specs or approvals.
• Strong fundamentals and learn fast.
• Care about product value and customer needs over technical purity.
• Take infra seriously.
• Think about blast radius, trust boundaries, and what happens when your code is in the path of every customer's agents.
• Can read unfamiliar code, reason from first principles, and explain your tradeoffs.
• Comfortable across the stack (TypeScript, Python, CockroachDB), or you pick up new languages, protocols, and domains fast.
• Excited to build with agents, and to learn when they help and when they hide a problem.
• Already build with AI every day and want room to move without heavy process.

Nice To Haves

• Developer-facing products, protocol or gateway work, or infrastructure at scale.
• Background in security, identity, or permission systems.
• Contributions to open source, MCP servers, or agentic frameworks.
• Design sensibility: engineers who care about design, designers who think about infrastructure.

Responsibilities

• Own features end to end, from conception to production, across our gateway infrastructure, enterprise deployments, and agentic systems.
• Build the UI when the product needs a better one.
• Fix connectors when they break during a security review.
• Shape the problem, make architecture, product, and UX calls.
• Harden enterprise paths.
• Design connectors.
• Protect security-sensitive surfaces.
• Catch generated code that is quietly wrong.
• Build and deploy agents on the same platform we sell.

Benefits

• Competitive compensation and meaningful equity.
• Unusual scope and ownership of features that ship to enterprise customers.
• Building and deploying agents on the same platform we sell.
• Direct access to the founders, customer context, and product direction, with mentorship as you grow.
• Health benefits, on a team that puts family and health first.
