Superbuilder, AI Tooling & Autonomous Agents

We believe that the onchain platform is the most important builder platform since the internet (“online”). We believe that the onchain platform should be open source, free to use, and globally available. And we believe that in order to make it really work, we need all hands on deck, working together to scale in a secure, decentralized, easy-to-use way.

At Base, we live by our Stay Based values: we do the right thing, work hard, stay optimistic, prioritize the team, and push creative boundaries—all while building the future of onchain. We value a Zone 3+ work ethic, where our team rises to the challenge, embraces hard weeks, and makes small to significant personal tradeoffs when necessary to drive impact and innovation.

Base is incubated within Coinbase and plans to progressively decentralize in the years ahead. We believe that decentralization is critical to creating an open, global crypto economy that is accessible to everyone.

Base is built on Optimism’s open-source OP Stack. We’re joining as the second Core Dev team working on the OP Stack to ensure it’s a public good available to everyone; and contributing a portion of sequencer revenue to funding public goods.

About us

We’re building the next generation of AI-native tools that fundamentally transform how software teams build, collaborate, and ship. Our mission is to 100x organizational productivity and unlock entirely new workflows by embedding AI agents into the core of product development.

We believe the best teams in the world will soon have AI teammates working alongside them - writing code, filing PRs, managing backlog items, writing docs, and more. You will join to make that future real.

What You’ll Do

As a Superbuilder, you’ll be one of the earliest engineers shaping how AI agents are built, deployed, and integrated across teams and products in Base. Your work will directly impact how developers write software and how entire product teams collaborate with agents.

• Build AI-first tools that massively boost developer productivity
• Create autonomous agents that integrate with real-world tools (GitHub, Slack, Linear, Figma, etc.)
• Design agents that become full-fledged team members — contributing to codebases, responding in threads, even running retros and handling follow-ups
• Collaborate closely with engineering, product, and design teams to deploy agents into our internal workflows
• Package these agents into SDKs, APIs, or frontends for broader adoption in external products
• Prototype quickly, ship fast, and obsess over real-world performance, latency, and UX

You Might Be a Fit If You...

• Have strong engineering instincts and love building full-stack systems end-to-end
• Are deeply obsessed about the intersection of AI, agents, and productivity
• Have deep experience building LLM-powered tools (LangChain, OpenAI, Anthropic, Agents, etc.)
• Have shipped agentic workflows before and deeply understand how agents function in production
• Prioritize pragmatic solutions and outcomes above technicalities and artificial barriers
• Thrive in fast-paced environments with high agency and autonomy, and are unafraid to break through walls.
• Experience integrating AI into dev tooling and collaboration tools with rapid feedback cycles

Nice to Haves

• Previous startup or zero-to-one product experience
