Senior Backend Engineer, Core Services

Apify is the largest marketplace of tools for AI. On Apify Store, tens of thousands of Actors, purpose-built tools for the web, help people and AI agents get real-time data, track competitors, generate leads, and connect apps. Anyone can build one and earn from it.

Apify is looking for a Backend Engineer for the Foundation group. The Foundation group takes care of the core of the Apify platform, both for product and tech.

What the group is responsible for:

• Running Actors end-to-end, from the Start button in the Console to the container or microVM running on our servers.

• Storages where the Actors save their progress or output, from the underlying databases to the frontend, rendering the storage contents.

• Actor Standby, our way of deploying Actors as real-time, synchronous services.

• Apify Proxy and Unblocker, our services to avoid being blocked while accessing the internet

• Our public API (the framework, not each individual endpoint).

• Our Console (the framework, not every feature in it).

• The AWS infrastructure on which all the Apify platform apps are deployed.

• The deployment process of those apps.
