• Evaluate and Recommend Technology: Lead partner evaluations and proof-of-concepts for emerging B2B capabilities and vendor technologies.
• Deliver Enterprise-Ready Documentation: Maintain architecture blueprints, system documentation, and reusable patterns for development and operational use.

• Experience with BSS/OSS systems, commerce engines, and 3rd-party vendor ecosystems.
• Strong understanding of federal compliance requirements, security standards, and data protection in the context of enterprise customers.

 

Preferred Qualifications

• Deep familiarity with cloud-native development (AWS, Azure), container orchestration (Docker, Kubernetes), and API-first integration strategies.
• Experience with federal and large enterprise customer constructs, including onboarding, account lifecycle management, and secure identity.
• Strong leadership presence and ability to communicate effectively across technical and executive partners.
