Summary Generated by Built In
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:
They're building the next generation of web scraping platform - new high-scale product endpoints, designed Go-first. We're looking for a strong backend engineer who wants to grow into Go and likes owning real problems at scale.

In this role, you’ll:

  • Design and build new backend services and product endpoints.
  • Work across our current Node.js/TypeScript core while new components grow in Go.
  • Write clear, tested, documented code that delivers real business value.
  • Partner with engineers to shape architecture and review each other's work.

Your skills & experience:

  • 5+ years of backend development experience (any language).
  • Some hands-on Go, or a genuine drive to build in it — including a solid grasp of syntax, best practices, and standard libraries in Go or another language.
  • Strong understanding of distributed systems and building for scale.
  • You use AI coding tools (Claude, Copilot, Cursor, Codex or similar) as part of your daily workflow - and you're curious about where AI fits into production systems, not just your editor.
  • Proactive, ownership-driven mindset and solid English and Lithuanian language knowledge.

Nice to have:

  • Familiarity with React/JS to understand how backend logic is visualized.
  • Skilled in using Docker and Kubernetes for deployment and orchestration.
  • Experience leading R&D initiatives and/or introducing new technologies/AI tools.

Salary & Benefits:

  • Gross salary: from 6000 EUR/month. Keep in mind that we are open to discussing a different salary based on your skills and experience.
  • Growth & Learning: 40+ internal learning options, external conferences, mentorship, and year-round knowledge-sharing.
  • Health & Well-being: Private health insurance, psychotherapy, on-site well-being consultants, 24/7 gym access, and a wellness app.
  • Celebration & Community: Team events, an overseas workation, quarterly team-building budgets, and plenty of ways to mark milestones together.
  • Plus bonus vacation days, paid life-moment days off, barista coffee, and all the tools you need. See the full list of benefits here: https://career.oxylabs.io/blog/our-work-benefits/.
