Systems Engineer

About the Team:

The mission of our team in Allegro is maintaining and tuning Kubernetes (running in on-prem and 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 the FOSS, we develop it.

Your main responsibilities:

• Operating running Kubernetes systems

• Working in the spirit of the GitOps philosophy

• Automating and optimizing tools related to our work (most often related to Kubernetes)

• Implementing CI/CD pipelines

• Creating tools according to our needs and requirements

• Holding on-call duty 24/7

We are looking for people who have:

• Linux knowledge (especially Ubuntu) – storage management, installation, configuration, admin experience

• Knowledge of the network technologies – TCP/UDP, HTTP, SSL

• Knowledge of Kubernetes and container technologies

• Knowledge how to work with these technologies – Git, Bash, Docker/Containerd

• Analytical thinking – how to solve problems and drive to do it

• Good knowledge of English (intermediate) – you don’t need to speak like a British lord, but every day you’ll communicate and write in English

The following are also a plus:

• Automation in Terraform

• Public Cloud concepts and experience: GCP/ Azure / AWS

• On-prem Kubernetes experience (build environments, analyze problems)

• Any of these technologies – Helm, Calico, GitLab/Github, Vault, Consul, BGP, Argo

What we offer:

• Our technology stack is:

  • main point of interest: Onprem Kubernetes clusters 

  • we also integrate with public cloud Kubernetes offerings

  • tech teams integrations: Prometheus, ELK, Artifactory, etc 

  • we handle all of onprem K8s cluster operations: updates, installations, maintenance 

  • we are responsible for architecture of backend micro services engine

  • we go from managing services at the IaaS level to diving into drivers and BIOS settings as needed

• We operate on a large scale:

  • architecture composed of over 1 000 microservices divided into domains

  • communication asynchronously over the Hermes data bus based on Kafka (100 000 rps of incoming traffic)

  • traffic between services, measured by Service Mesh, is almost 2 million rps

• The IT team is made up of over 1 700 members who have shared their knowledge at multiple conferences, such as DevDays, Geekon, Code Europe, Perspektywy Women In Tech Summit, Devoxx, Confitura, and co-create a blog: allegro.tech

• Microservices – a few thousand microservices and 1.8m+ rps on our business data bus

• Big Data – several petabytes of data and Machine Learning used in production

• We practice Code Review, Continuous Integration, Scrum/Kanban, Domain Driven Design, Test Driven Development, Pair Programming, depending on the team

• To match the scale, we also focus on building entire Platforms of tools and technologies that accelerate and facilitate day-to-day development, and we ensure the best Developer Experience to our teams

• Technological autonomy: you get to choose which technology solves the problem at hand (no need for management’s consent). You are responsible for what you create

• Our deployment environment combines private Data Centers (tens of thousands of servers) and Public Clouds (Google Cloud and Microsoft Azure)

• Over 100 original open source projects and a few thousand stars on github

• We organize Allegro Tech Live event, a 100% remote version of our offline Allegro Tech Talks meetups, and we make guest appearances at the invitation of such communities as Warsaw AI, JUG (Poznań, Łódź, Lublin, Wrocław), WG .Net, Dare IT, Women in Tech Summit

• We focus on development as well. We organize hackathons and internal conferences (e.g. the annual Allegro Tech Meeting), our employees regularly participate in events both in Poland and abroad (Europe and USA), and each team has its own budget for training and study aids. If you want to keep growing and share your knowledge, we will always support you
