Want servers with 600k persistent TCP connections each? We got you covered.
Want in-house anycast DNS servers backed by BGP/BFD serving hundreds of thousands of users? Check.
Want in-house globally distributed Content Delivery Network (CDN) serving over 3,5Tbps of video traffic each night? You bet.
Want to orchestrate 1000s of physical servers that are highly available? Gotcha.
You think developers should write their own pipelines, monitoring and alerting and deploy their apps by giving them self-service tooling? We think there is no other way. Are you bothered by strange spikes in graphs that you can’t explain? It pains us too and it can affect our sleep sometimes.
Does saying “I’ll do it manually on the server” causes feelings of disgust, maybe even an eye twitch? Us too.
If these questions tick your boxes come join us (we sometimes do have cookies,). We are big believers in Open-Source Software, and we like engineering things. We believe in creating highly performant solutions and we like optimizing them to their limits. We are not afraid to code stuff, both big and small. We like our developers happy, so we give them tools to self-service most of their needs. We think that if we do it right, we don’t need to scale infinitely with our system.
We can promise you it will never be boring, and that you will never stop learning.
What you'll have here:
- In-house products: Working on products that we use every day and have millions of users. Some of them are your friends, neighbors, family members. We are our own clients. Our opinions and experiences are directly shaping the products that we design and create.
- People: You will work with experts, community leaders and senior engineers who made these products from scratch. They will reveal to you how the whiteboard idea turns into a worldwide platform.
- Tech stack: We are tech agnostic and programming languages are just a tool, but they can make our job easier if we choose the right tool for the job.
- Engineering mindset: We are engineering our solutions from ground up using open-source tools and customizing them to our needs. We worry about performance, we analyze and observe our system. We are not throwing money at the problem, we actually care if things could be more optimal.
- Career growth: We strongly believe in feedback culture and development plans.
Your Responsibilities:
- Fully automate all DevOps processes, e.g. servers / VM clusters / Kubernetes provisioning, deprovisioning, security updates, intrusion detection, log collection and analysis, backups, service mesh, Kafka clusters, ML platforms, Big Data platforms, etc.
- Development of internal services for system analytics and monitoring.
- Create “self-service” CI/CD infrastructure for development teams.
- Advise the development team on best practices throughout the design process of their applications, to ensure that they can be delivered to manageable and highly available production environments.
- Design and implement highly available and scalable infrastructure to support our products.
- Mentoring less experienced colleagues.
- Documenting your designs and solutions.
- Implement best security practices on a large-scale custom-built hybrid infrastructure.
- Proposing, planning and implementing further improvements.
What we're looking for:
- At least 4 years of relevant work experience: DevOps/Infrastructure, Systems Administration, SRE, and/or Development.
- Experience working with infrastructure operations and automation tools (Ansible, Terraform).
- Proficient knowledge of and passion for the Linux operating system (Ubuntu, Debian, CentOS).
- Experience with Kubernetes and any of container runtimes.
- Experience working with monitoring (Prometheus, Grafana, Loki or similar) and alerting tools (Alertmanager or similar).
- Familiar with SRE concepts and an understanding of observability and availability, SLOs/SLIs/SLAs.
- Experience working with CI/CD tools (Jenkins, ArgoCD, Gitea [VR1] or similar) and process automation platforms (Rundeck or similar).
- Experience working with Virtualization environments (Proxmox, VCD or similar).
- Experience with managing and optimizing web servers (NGINX) and load balancers (HAProxy) for high loads and high availability.
- Knowledge of modern scripting languages (Python, Go or similar).
- Advanced knowledge of network protocols, DNS, firewalls, SSO.
- High proficiency in written and spoken English.
- Good verbal communication and good interpersonal skills.
What will be considered as a bonus:
- Experience with on-premises Kubernetes deployment, clustering, optimisation and maintenance.
- Experience with highly scalable storage systems (Ceph).
- Experience with AWS, Apache Kafka[VR2] , HashiCorp Vault, PowerDNS, MQTT brokers, service mesh.
- Experience with tools like Cilium, Istio, Envoy.
- Experience with eBPF for tracing and profiling.
- Experience with running containerized workflows on the edge.
- Experience with hybrid cloud infrastructure.
- Experience with distributed tracing systems (Jaeger, New Relic or similar).
- Experience with deployment, clustering, optimisation and maintenance of databases (PostgreSQL, MySQL or similar).
We have more than cookies:
- Flexible working environment – we have offices in Belgrade and Ljubljana.
- Private healthcare.
- Gifts for your special days.
- “Healthy” Friday – not always healthy snacks on Fridays.
- 25 vacation days.
Here’s the thing: We come to work every day to face exciting and challenging creative problems. And we come armed with an extremely Agile mindset and a bundle of opportunities for career growth and personal development plans.
We come and go relaxed and happy as we know United Cloud has our back, making sure our work and private life are in a perfect balance. Our team is made of smart people, ambitious enough to make the change and brave enough to move boundaries. There is always room for more individuals like that, so send us your CV.
