Senior Software Engineer, Builder Studio

Apollo is the AI-powered go-to-market platform that helps revenue teams find, engage, and convert their best customers. We combine a database of more than 210 million contacts and 35 million companies with an agentic end-to-end GTM platform, and more than 500,000 companies rely on us to run their go-to-market motion. We are profitable, growing fast, and rebuilding the product around AI and agents.

About Builder Studio

Builder Studio is Apollo's new product for building custom GTM software in plain English. A RevOps lead, GTM engineer, or founder describes the tool they need, and Builder Studio plans it, generates real code, and turns it into a working app they can preview, refine through conversation, publish, and share with their team.

Every app is made of four building blocks: Pages for the interface, Databases for structured records, Workflows for visible backend logic and scheduled jobs, and Agents that reason over Apollo context and take action. What makes it different from a generic app builder is that Apollo's data, enrichment, sequences, deliverability, and CRM sync are native building blocks, not bolted-on third-party integrations.

It is one of Apollo's flagship AI bets. The product is in the hands of early design partners now and is heading toward broad launch, which means the next year is about taking a working product and making it reliable, secure, and loved at scale.

Your role and mission

You will own major slices of Builder Studio end to end, across the builder experience customers see and the systems that make generated apps actually run. You will work on problems most engineers have never touched: an agent that writes and edits software on a customer's behalf, a runtime that safely executes that code with the user's own Apollo permissions, and an interface that makes all of it understandable to someone who has never read a line of code.
