Backend Engineer for AI/LLM Team (Python / TypeScript)

Apify's mission is to make the web more programmable 💻.

Why? Because we believe that humans have better things to do than fill in internet forms, compile Excel sheets of copy-pasted data, or watch thousands of videos to determine whether they include a specific brand logo.

Those are jobs for a machine.

And just as we have tools that make our lives easier in the real world, we should also have tools to make our lives easier on the web.

We use web automation to robotize unsubscribe flows to save people money, and we collect billions of rows of data from all over the world for science, market research, or finding lost children.

Fortune 500 companies and small startups alike need this power to make great business decisions 🚀.

Data is driving the recent AI revolution. Companies like Intercom use Apify to extract text content from the web, feeding their vector databases and fine-tuning or training large language models (LLMs) such as ChatGPT and LLaMA.

We’re building a new product team focused on AI ecosystem and looking for a backend engineers interested in AI tooling.

Are you the engineer who will help us teach LLM agents to control the browser with all its challenges, such as dynamic websites, forms, or complex navigation?

Or to extract data from the mess of React-rendered HTML without the help of humans?

Yes?

Then stop by for a ☕. We’ll have a lot to talk about and then to work on!
