Job description

Want to build and run large-scale systems that power products used by millions?

Join Similarweb’s new Prague hub and take a leading role in designing, automating, and scaling the infrastructure behind one of the world’s most advanced digital intelligence platforms.

You’ll work hands-on with cloud, data, and automation — solving tough reliability challenges and helping our teams ship faster and safer at massive scale.

⚙️ What you’ll do

Design, build, and maintain scalable, reliable, and secure infrastructure across AWS and GCP
Develop automation and internal tooling in Python, Go, or Node.js
Define and manage Infrastructure as Code (Terraform, Pulumi) for consistent, repeatable deployments
Implement monitoring, alerting, and observability systems for proactive incident detection
Collaborate closely with engineering teams to improve performance, scalability, and developer experience
Lead post-incident reviews, root cause analysis, and reliability improvements
Participate in on-call rotations — and make sure the same alert never fires twice

What you bring

3+ years of experience building or operating large-scale distributed systems
Strong coding skills in Python, Go, Node.js, or Java
Deep understanding of AWS/GCP, networking, load balancing, and caching
Hands-on experience with CI/CD pipelines (Jenkins, GitLab CI, CircleCI)
Familiarity with Docker, Kubernetes, or Nomad
Automation-first mindset and ownership mentality
Fluent in English (Czech is a plus)

🚀 Why you’ll love it here

Work on mission-critical systems that power Similarweb’s global data platform
Build real infrastructure — not just operate it — with full ownership and autonomy
Join a Prague-based engineering team with global reach and local impact
Shape how reliability, performance, and scalability are done at Similarweb
Learn, grow, and make your mark in a brand-new site with startup energy and global resources
