About the company
Apify is the largest marketplace of tools for AI. Thousands of Actors helping people and agents get real-time web data, track competitors, generate leads, or integrate their apps. Actors are built by a global creator community that now earns more than $1.5 million every month.
Responsibilities
- Build and improve Store search: the relevance, ranking, and query understanding that gets users and AI agents to the right Actor fast.
- Integrate and experiment with recommender systems that surface the most relevant Actors for each user, context, and use case.
- Develop the Store surfaces in React/TypeScript: search results, category and listing pages, and the end-to-end "find the right Actor" experience.
- Build the backend behind discovery: scoring services, quality-evaluation pipelines, and the data processes that keep Store categorization accurate as the catalog grows.
- Run A/B experiments to measure how discovery changes move activation and retention, and let the results decide what ships.
- Work with product, design, and data to turn "help users and agents find the right tool" into concrete, measurable improvements.
Requirements
- 3+ years of professional experience building fullstack web applications, with a track record of shipping and owning user-facing features. We're aiming for a senior hire, but we'll happily talk to strong mid-level engineers ready to step up.
- Strong skills developing and debugging modern single-page applications in TypeScript/React, with Node.js-based backends.
- Comfort owning a problem end-to-end across the stack, from the UI a user touches to the services, scoring, and data behind it.
- An experiment-driven mindset: you use A/B tests and metrics to decide what actually works.
- Good communication skills in English, and a collaborative approach with product, design, and data.

- Space, support, and autonomy for personal growth, with a direct impact on our success
