Backend Developer (Golang)

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.

What’s in store for you:

• You’ll be solving complex challenges and maintaining our own infrastructure with 60PB+ monthly data traffic. Here are its scale and maturity in numbers:
• 6PB+ Ceph storage
• 60PB+ monthly data traffic through our systems
• 300k+ service requests/sec processed
• 500k+ Kafka messages/sec streamed

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.

What you'll do:

• Design and build systems and solutions that scale effortlessly
• Write clean, tested, and documented code that delivers real business value
• Own the entire development cycle — from research and prototyping to deployment
• Deliver and review technical designs, code, and documentation
• Contribute to technical decision-making in an early-stage, fast-growing project
• Create, review, and maintain multiple microservices, optimizing them for performance and stability

• Deep knowledge of Golang
• Some experience with — or genuine interest in — other programming languages
• Solid understanding of SQL and NoSQL databases: how they work, how to write optimized queries, and how to debug them
• A firm belief in why automated tests can save the world
• Experience with (or strong curiosity about) real-time data processing and event streaming
• Passion for technology and a habit of constantly trying something new
• Hands-on experience with some of the technologies we use extensively: Docker, Kubernetes, microservices, Kafka, MySQL clusters, GitLab CI, Redis
• Comfort with ambiguity and rapid change
• You value playful communication over corporate BS

Nice to have

• Experience with DevOps practices (deployment pipelines, automation, etc.)
• A clue on how web scraping works

• 40+ internal learning options, external conferences, mentorship, and year-round knowledge-sharing.
• Private health insurance, psychotherapy, on-site well-being consultants, 24/7 gym access, and a wellness app.
• Team events, an overseas workation, quarterly team-building budgets, and plenty of ways to mark milestones together.
