• Experience level: Mid level, Senior

About the role

• Site Reliability Engineer ensuring platform stability and managing AWS migration. Focused on hands-on maintenance work and engineering automation for healthcare staffing platform.

Responsibilities

• Split your time 50/50 between keeping the lights on (maintenance/support) and active development (improving automation and tooling).
• Contribute to major roadmap projects, such as the migration of our infrastructure stack to a different AWS region to improve cost and availability.
• Participate in our "Sheriff" rotation (approx. 1 week per month during standard office hours), acting as the primary point of contact for infrastructure ad-hoc support to prevent interruptions for the rest of the team.
• Investigate logs, debug crashing pods, and troubleshoot complex distributed system issues using observability tools - going deeper than just deploying charts.
• Use modern AI tools (ClaudeCode, Cursor) to automate toil and speed up workflows, maintaining a realistic balance between using new tech and relying on proven engineering principles.

Requirements

• Hands-on production experience with Terraform (or Pulumi/CloudFormation), managing version-controlled, modular infrastructure through an infrastructure-as-code–first approach.
• Ability to spin up pods, debug broken deployments, and manage resources via YAML. We don't need you to architect a cluster from scratch on Day 1, but you must be comfortable operating inside one.
• Strong understanding of web application fundamentals (HTTP/S, SSL, GET/POST) to troubleshoot connectivity issues between services effectively.
• A programmatic mindset. Whether it’s Python, Go, or Bash, you write code to fix problems rather than fixing them manually every time.
• An open but skeptical attitude toward AI. You are willing to use LLMs to be more efficient, but you verify the output and don't use them as a crutch.

Benefits

• Additional vacation days for better work-life balance.
• Modern office in Warsaw’s Powiśle district with Vistula River views, recreational facilities, and great nearby restaurants.
• Thoughtfully designed private medical package to take care of what matters most.
• Sports card to fuel your active lifestyle.
• Life and accident insurance for peace of mind.
