Job description

About Crustdata

The way information on the internet is consumed is changing - from humans searching pre-crawled pages to AI agents doing real-time targeted crawling from sources of truth. But there’s no “Google” for AI agents… yet.

At Crustdata, we’re building that. We serve 300+ customers and we’re growing fast. Backed by Y Combinator, General Catalyst, SV Angel, A Capital, and Liquid 2 Ventures. Our mission: be the default way AI agents interface with the internet.

What you’ll do

You’ll be a technical partner to revenue and product teams: build rapid prototypes and demo tooling, ship customer integrations, and turn those into repeatable solutions that help customers (and help us close deals).

• Build rapid prototypes and POCs for prospects
• Create demo tooling + reusable templates to accelerate sales
• Implement turnkey integrations (APIs, pipelines, dashboards) and hand off to Customer Success
• Connect Crustdata to customer systems + third-party tools
• Turn prototypes into repeatable reference implementations into the product
• Build AI agents for internal sales and customer success workflows
• Share feedback with Product & Engineering and write docs/playbooks
• Optional: Join occasional on-site workshops

Who you are

• Undergrad (or equivalent) CS/EE/Math background
• Strong coding skills in Python and/or TypeScript/JavaScript
• Comfortable building real things end-to-end (projects, OSS, hackathons, research, prior internships - all count)
• Solid fundamentals + you learn fast
• Bonus: SQL/data curiosity (warehouses/ETL/analytics), APIs/integrations

Why this internship is different

• You ship. You’ll work on real customer problems with real stakes.
• You learn fast. Small team, high trust, direct founder access.
• You matter. Your work will influence product direction and revenue.
• Future upside. Strong interns are top-of-list for full-time.

If you want an internship where you ship real stuff that customers use (and you work directly with founders), this is it.
