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: 30 000 PLN/month  - 34 000 PLN/gross.
