Job description

Location: Poznań, PL, 61-569

Team: Technology

Contract Type: Employee

Job Description:

The mission of our team at Allegro is maintaining and tuning Kubernetes (running on-premise and in Public Cloud) and its ecosystem. Our work is a never-ending challenge that gives us an opportunity to learn new technology trends from the world of FOSS and run them. If we don’t find what we need in FOSS, we develop it ourselves.

This is the right job for you if you:

• Have proven, real-world experience with Linux (especially Ubuntu – storage management, installation, configuration, administration).
• Have solid hands-on experience with Kubernetes and container technologies (Docker, Containerd).
• Daily use Git and Bash,
• Know networking fundamentals well (TCP/UDP, HTTP, SSL).
• Demonstrate strong analytical thinking – you know how to solve complex technical problems and drive them from start to finish.
• Have proficiency in English and Polish (minimum B2).

Familiarity with the following is a plus:

• Public Cloud concepts and experience (GCP, Azure, or AWS).
• On-premise Kubernetes experience (building environments, analyzing and troubleshooting issues).
• Tools such as Helm, Calico, GitLab/GitHub, Vault, Consul, BGP, or Argo.
• Programming languages like Python or Golang.

In your daily work, you will handle the following tasks:

• Operating and maintaining production Kubernetes systems running on-premise and in Public Cloud.
• Working in accordance with the GitOps philosophy.
• Automating and optimizing tools related to team operations and the Kubernetes ecosystem.
• Building and implementing CI/CD pipelines.
• Creating and developing custom tools according to team needs and requirements when FOSS options fall short.
• Participating in daily meetings, handling backlog tasks, and resolving business‑critical issues as they arise.

What's in it for you:

• Flexible working hours in the hybrid model (4/1) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work.
• Annual bonus up to 10% of the gross annual salary (depending on your annual assessment and company results).
• Well‑located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms).
• A 16" or 14" MacBook Pro with Apple Silicon processor and 36GB RAM, or a corresponding Dell with Windows (if you don't like Macs) and all necessary accessories.
• A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).
• English classes that we pay for related to the specific nature of your job.
• A training budget, inter-team tourism, hackathons, and an internal educational platform (MindUp) with training courses on technologies, work organization, and soft skills.
• An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal.
• Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy.
