Job description

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’s 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

In this role, you’ll:

• Own and evolve Webshare's production infrastructure – lead the migration from Docker Swarm to Kubernetes (or hybrid K8s + Ansible)
• 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 owned CI/CD pipelines end‑to‑end (GitLab CI or equivalent)
• 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. 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, gym allowance and a wellness app
• Celebration & Community: Team events, an overseas workation and plenty of ways to mark milestones together
