• Strong scripting skills (Bash, Python) for automation and toolchain development
• Understanding of security best practices, certificate management, and encryption in AWS
• Experience working in agile teams with sprint-based delivery (2–3 week sprints)
• Great communication skills in English – ability to interact with client's PM and technical stakeholders and multi-cultural team
• Self-directed and able to make informed decisions with limited documentation
• Willing to travel to the EU and the USA for business trips

Your Responsibilities:

• Conduct an initial assessment of the existing AWS infrastructure, CI/CD pipelines, and deployment processes; provide recommendations and a prioritized improvement plan
