Site Reliability Engineer

O projekcie: The Collaboration As a Site Reliability Engineer, you will ensure our Marketplace platform remains stable, secure, and highly available. In this role, you will act as a proactive partner to engineering teams, focusing on incident prevention and infrastructure excellence. After achieving a record-low 6 minutes of downtime in 2025, your primary objective will be maintaining this standard while helping with a major migration to a new AWS region. This cooperation blends high-level engineering and automation with hands-on infrastructure optimization (reducing tech debt, strengthening observability, and refining deployment pipelines). We operate in a "you build it, you run it" culture. Thanks to our US-based counterparts and a follow-the-sun model, service availability is managed globally, typically requiring your primary availability during Warsaw business hours with no scheduled duties after 5:00 PM CET. Location & Collaboration We are looking for someone based in the Warsaw Metropolitan Area. While we don't enforce a fixed desk schedule, the team typically synchronizes in-office on Tuesdays and Wednesdays to facilitate face-to-face project alignment. Wymagania: - Practical experience with Terraform, CloudFormation, Pulumi, or similar tools on complex, production-level systems (beyond hobbyist-level work).- Hands-on experience managing environments within AWS and Kubernetes.- A strong programming background (any language) and a programmatic approach to solving infrastructure challenges.- Deep understanding of web application basics (HTTP, HTTPS, SSL, GET, POST, PUT) to effectively troubleshoot connectivity and service layers.- A realistic, skeptical attitude toward tools; you choose the right tech for the problem, not just the latest trend.- High "team fit" with the ability to engage in constructive disagreement to reach the best technical outcomes. Codzienne zadania: - Balance your efforts between proactive automation/tooling (50%) and platform maintenance/optimization (50%). - Act as a designated "Point of Contact" for infrastructure support on a rotational basis (approx. 1 week per month) to ensure smooth service delivery. - Troubleshoot complex distributed system issues, investigate logs, and debug pods using modern observability tools. - Utilize modern AI tools (ClaudeCode, Cursor) to automate repetitive tasks and streamline workflows. - Help with the migration of our infrastructure stack to a new AWS region to optimize costs and availability.
