Software Engineer (Go)

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

Join us at a stage where your work actually moves the needle. The product is still young, the customer base is growing fast, and there’s a lot of space to shape both the tech and the product itself. You won’t be just closing tickets – you’ll be helping to decide what we build, how we build it, and how it scales.

You’ll work with a modern stack (Go, Kubernetes, MySQL, Kafka, Redis, monitoring, headless browsers) and real-world problems around scraping, browser automation, stealth techniques and AI agents. If you like digging deep into how things actually work – from infrastructure to browser internals – you’ll feel at home.

It’s a small, hands-on team where ownership is real: you can talk directly to customers, ship features end-to-end, and see your impact quickly. The flip side: the product is growing and changing, so we’re looking for someone who’s flexible, curious, and wants to grow together with it – not someone who needs a fixed roadmap and golden processes. If you enjoy building, experimenting and improving both the product and yourself, this is a good place to do it.

Your day-to-day::
• Develop systems and solutions that can scale easily as the product and customer base grows.

• Own the full development cycle – from research and prototyping to deployment and production.

• Deliver and review technical design, code, and documentation.

• Take part in technical decision-making in an early-stage, fast‑growing product.

• Work directly with customers when needed: help investigate and solve their issues, and bring ideas back to the team.

• Look for and suggest product improvements based on real customer problems and your own insights.

• Actively contribute to growing and shaping the product from a fairly early stage – understand the product, its problems and opportunities, not just the technical side.

Your skills & experience::
• Solid hands-on experience with Go.

• Production experience with Kubernetes – you should understand how to deploy and maintain services.

• A good grasp of the underlying infrastructure, not just how to write application code.

• A genuine desire to work with an early-stage, growing product and take ownership beyond just coding tasks.

• Flexibility – you are comfortable with the fact that in a fast-growing product, priorities and direction can change quickly.

• Good communication and a collaborative mindset for a small, hybrid team.

NICE TO HAVE REQUIREMENTS:

• Experience with headless browsers (e.g., Playwright, Puppeteer) and web scraping/automation.

• A deep understanding of the scraping niche, including stealth techniques and advanced headless browser principles.

• Familiarity with AI agents and ideas on how they could leverage headless browsers.

• Practical experience with our stack: MySQL, Kafka, Redis, Grafana, Sentry, ELK.

Our Salary::
• Gross salary: from 22 000 - 29 000 PLN/month. Keep in mind that we are open to discussing a different salary based on your skills and experience.
