Opis

We’re looking for an experienced Senior Backend Engineer to join a project in the hosting technologies domain. You’ll work on a distributed Python-based backend platform, the core component of our infrastructure. The role combines hands-on coding, defining functional and non-functional requirements, and designing new solutions from scratch. This is a technically challenging environment, with a fast onboarding process and full remote flexibility.

You’ll work primarily with Python, but this is not a typical web-backend position. The ideal candidate is someone who understands system-level development, knows how Linux works under the hood, and can design and build backend components that integrate deeply with the OS and network layer.

This is a highly technical role for an engineer who enjoys solving complex infrastructure problems, rather than relying on managed cloud services.

Nasze wymagania

  • 5–7 years of experience in backend software engineering
  • 3+ years of hands-on experience with Python
  • Strong knowledge of Linux (administration, architecture, troubleshooting)
  • Proficiency in at least one additional backend language — e.g. C, C++, Perl, Go, Lua, etc.
  • Experience with distributed systems and backend architectures
  • Solid knowledge of databases (MySQL, PostgreSQL, Redis)
  • Understanding of and ability to write automated tests
  • Hands-on experience with some of the following:
    • Kubernetes, Docker, RabbitMQ, Zookeeper, Kafka
    • Web & mail servers: Apache, Nginx, Postfix, Dovecot, LDAP
    • CI/CD tools: Git, GitLab, Jenkins
  • Good understanding of TCP/IP protocols and network communication
  • Ability to work independently and debug complex production issues
  • Fluent Polish and good English

NICE TO HAVE

  • Experience with ZeroMQ or other distributed messaging systems
  • Knowledge of hosting or ISP environments
  • Familiarity with IaC tools (Ansible, Terraform, OpenStack, Vault)
  • Understanding of low-level OS mechanisms, such as processes, cgroups, and networking
  • Willingness to work outside of fully-managed cloud ecosystems

Twoje zadania

  • Develop and enhance a Python-based distributed backend for a large-scale hosting platform
  • Design and maintain system-level components
  • Create architecture for new modules and improve existing ones
  • Troubleshoot and resolve complex application and infrastructure issues (last-line production support)
  • Support CI/CD and containerization processes (Docker, Kubernetes, LXC)
  • Collaborate with the engineering team to define requirements and shape the technical roadmap

To oferujemy

  • Relocation package (4500 PLN total value), paid in three installments (1500 PLN per month)
  • Benefits: Extended medical care (over 2000 medical facilities in Poland, 80 in Kraków) for you and your family; Multisport Benefit card; Life insurance
  • Remote work option
  • Dofinansowanie zajęć sportowych
  • Prywatna opieka medyczna
  • Ubezpieczenie na życie
  • Paczki świąteczne
  • Imprezy integracyjne
  • Elastyczne godziny pracy
