Senior Full-Stack & Platform Engineer

DevOps / Platform Engineer / Go Developer · SoftServeBucharest, Romania

Joined Oct 2026

Senior full-stack and platform engineer with 7+ years of experience. I build backends in Ruby on Rails and Go, and the platforms they run on: Kubernetes operators with kubebuilder, GitOps with Flux CD, event-driven autoscaling with KEDA, and lean k3s clusters on Hetzner.

I like making infrastructure boring in the best way. That means reproducible deploys, security checks built into , and PostgreSQL, Redis and RabbitMQ setups the team doesn’t have to babysit.

Looking for an EU-remote platform/infrastructure or senior Rails role on a team where the product matters more than the tech for its own sake.
