Apify's mission is to help anyone get more value from the web with automation, AI agents, and web scraping.
Why?
We believe that humans have better things to do than filling forms, compiling huge Excel sheets of copy-pasted data, or watching thousands of videos to determine whether they include a specific brand logo.
Those are jobs for machines.
And just as in the real world, we have tools that make our lives easier, we should have tools to make our lives easier on the web.
Web automation has a profound impact. Our users automate service unsubscriptions to save people money, and they collect billions of rows of data from all over the world for AI training, protection of consumers, or finding lost children. We give AI chatbots the context to interact intelligently, and we’re developing novel ways to work with generative AI like ChatGPT.
To support this mission, we're looking for a Senior Backend Engineer to work on proxy infrastructure and unblocking.
Anti-bot systems are constantly evolving, and we need to keep our scraping infrastructure ahead of them. You'll expand Apify Proxy, research anti-scraping services, and build internal tools that use browser fingerprinting, human-like interactions, and session management to keep data flowing.
If you enjoy solving hard technical problems and contributing to open-source proxy libraries, this role might be for you.
