• Validate and oversee implementation activities to ensure network stability and design compliance during maintenance windows.
• Lead or support user acceptance testing (UAT), software validation, and interoperability testing as part of customer‑funded projects.
• Develop automation scripts and testing templates; conduct internal and customer workshops to share best practices.

• Soft Skills: Excellent analytical, problem‑solving, and communication skills, with the ability to work independently, manage timelines, and collaborate effectively in a global team.
• Language Skills: Fluency in Spanish or Portuguese is a plus.

Assets

• Experience with subsea networks or large‑scale optical network deployments.
• Familiarity with distributed systems and network architecture.
• Demonstrated ability to handle maintenance window activities under time pressure.
