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.

In this role, you’ll:

- Maintain high availability across hundreds of servers and ~50 services.
- Drive observability in cooperation with development team.
- Establish and enforce IaC practices, CI/CD pipeline reliability, and change management processes.
- Participate in the on-call rotation alongside backend developers.
- Respond to and lead incident resolution, run post-mortems and drive systematic remediation.
- Contribute platform tooling that improves developer experience and reduces infrastructure toil.
- Keep backend engineers informed and capable — no silos, shared infrastructure ownership.
Your skills & experience:
- Have built and operated highly available infrastructure at comparable scale — hundreds of servers, dozens of services, real production load.
- Hands-on K8s in self-hosted / bare-metal environments.
- Confident with Infrastructure as Code.

- Have been on call in a production environment.
- Proactive— surfaces problems before being asked, keeps the team informed without prompting.
- Scripting and development skills.
Nice to have:
- Led at least one major infrastructure migration - planned, executed, and stabilised it.
- Python and/or Go familiarity - backend is Python, edge services are Go.
- Exposure to proxy, networking-heavy infrastructure.
- Previous experience in a small team where developers shared infrastructure responsibility.
- Familiarity with edge clusters or split compute/edge architectures.
Salary & Benefits:
- Gross salary: 26 000 PLN/month - 34 000 PLN/gross. 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.
