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.
