We’re a team of 500+ professionals who develop cutting-edge proxy and web data scraping solutions for thousands of the world’s best known businesses, including Fortune 500 companies.

The team waiting for you:

We're scaling the development power of our Supply team, and we're looking for a Mid-Senior Backend Developer who lives and breathes Golang. At Oxylabs, you'll work on APIs and systems that operate at genuinely high loads — hundreds of servers handling hundreds of thousands of requests per second — in a fully containerized environment we've been running on Kubernetes in production for over seven years.

This is an early-stage, fast-growing project where you'll own real problems end to end, influence technical direction, and get your hands on big data every single day. If you value playful communication over corporate BS and get energized by scalability challenges, keep reading.
