• Partner with licensing, administration, Product, and customer-facing teams to deliver a consistent path from purchase to product activation.
• Write tests, design documentation, runbooks, and operational guidance; use rollout practices that support safe changes.
• Contribute to design and code reviews and support teammates through technical problem solving.

What You’ll Bring

• Strong ownership and sound judgment when working on customer activation paths where accuracy and reliability matter.
• Ability to reason about distributed workflows, failures, and recovery while keeping customer impact in view.
• Clear communication and collaboration across service boundaries and with Product and partner teams.
• Attention to detail and commitment to tested, observable, well-documented production systems.
• Ability to manage concurrent work, surface risks early, and learn from operational feedback.

Required Education / Experience

• Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
