Infrastructure Engineer (SRE)

Job Overview

You will keep our Marketplace platform stable, secure, and highly available - acting as a proactive partner to engineering teams to prevent incidents before they happen. In 2025, our platform saw only 6 minutes of downtime, and you will help us maintain that standard while executing a migration to a new AWS region.

This role blends hands-on maintenance work (reducing tech debt, improving deployments, strengthening observability) with engineering and automation that makes the platform easier to operate over time.

You won't be a "ticket mover" here. You will work in a "you build it, you run it" culture, but without the burnout. Thanks to our US-based counterparts, we operate a follow-the-sun model, meaning no scheduled on-call duties after 5:00 PM Warsaw time.

Key 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.

Required Qualifications

• 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.


• 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.
