Python Engineer DevOps Poland : Kielce, Kraków, Wrocław + Remote – PLN NET PER HOU

Overview

Virtus Lab is a leading European software consulting and engineering company. Our mission is to craft clean code and practical solutions with precision and purpose. We foster a dynamic culture rooted in strong engineering, ownership, and transparency, empowering professionals to make a substantial impact in the software industry.

The engagement involves collaborating with a specialized Dev-Tooling / Software Engineering stream focused on supporting a large-scale migration from a legacy in-house artifact storage solution to JFrog Artifactory.

• Docker — Advanced
• Relational & Non-relational databases (SQL, No
  
  SQL) — Regular
• CI/CD — Regular
• IaC (Terraform) — Regular
• Jenkins — Regular
• Artifactory — Nice to have

Smart Artifacts Engine

Artifactory will serve as the central repository across the enterprise for high-volume binary assets, compiled packages, software libraries, and large data files. Given the massive scale of the artifact repository and the complexity of the migration, this initiative is driven by software engineering and automation rather than standard operational Dev Ops tasks. The primary focus centers on developing robust, reliable developer tools and services to streamline the onboarding experience and automate workflows for engineering teams across enterprise environments.

• Developer Tooling Engineering:
  Designing, building, and maintaining automation scripts, CLI tools, and background services to facilitate seamless artifact migration and continuous integration.
• Onboarding & Workflow Automation:
  Delivering automated onboarding mechanisms for internal dev teams, simplifying dependency handling, package publishing, and access management.
• Dependency Management Optimization:
  Resolving complex dependency resolution challenges in Python and Docker environments during high-throughput repository transitions.
• Lightweight Backend Development:
  Creating internal REST APIs and microservices to support migration operations and integrating Artifactory into the existing tooling ecosystem.

The project team operates in a distributed setup between New York and London. With the primary Technical Lead based in New York, the engagement offers high flexibility, allowing seamless cooperation aligned with European business hours.
