Golang Developer (Senior)

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.

• You’ll be solving complex challenges and maintaining our own infrastructure with 60PB+ monthly data traffic. Here are its scale and maturity in numbers:

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.

• 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.

• 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.
