About the role

  • Define and document the target-state architecture for the Network Services domain, including SIP trunk consolidation, SBC configuration templates, and dial-plan normalization.
  • Identify and resolve enterprise DNS conflicts and IPAM-related issues across multiple legacy network environments.
  • Develop standardized configuration templates and architectural guardrails for Voice and SIP services to support large-scale automated deployments.
  • Design routing frameworks for emergency and authenticated communications, aligning with regulatory and compliance requirements while coordinating with client legal teams for approvals (e.g., e911, STIR/SHAKEN).
  • Define clear exit criteria and Definition of Done (DoD) for voice migrations, enabling consistent and safe execution by offshore delivery teams.
  • Contribute to architecture governance, including participation in architecture reviews, design approvals, and development of enterprise standards and reference architectures.
  • Collaborate with cross-domain architects (security, application, platform) on integrated design decisions.

Requirements

  • 10+ years of experience in enterprise network architecture with strong specialization in Voice over IP (VoIP), SIP trunking, and Session Border Controllers (SBCs).
  • Deep expertise in resolving DNS and IP addressing conflicts (IPAM) within large-scale network consolidation or M&A environments.
  • Proven experience designing dial-plan normalization across multi-vendor ecosystems (e.g., Cisco, Avaya, Microsoft Teams).
  • Strong understanding of US telecommunications standards and regulatory considerations; focus remains on architecture rather than carrier management or LNP execution.
  • Ability to translate complex voice configurations into standardized, reusable Low-Level Design (LLD) templates suitable for automated, factory-style deployment.
Benefits
  • Culture of Relentless Performance : join an unstoppable technology development team with a 99% project success rate and more than 30% year-over-year revenue growth.
  • Competitive Pay and Benefits : enjoy a comprehensive compensation and benefits package, including health insurance, and a relocation program.
  • Work From Anywhere Culture : make the most of the flexibility that comes with remote work.
  • Growth Mindset : reap the benefits of a range of professional development opportunities, including certification programs, mentorship and talent investment programs, internal mobility and internship opportunities.
  • Global Impact : collaborate on impactful projects for top global clients and shape the future of industries.
  • Welcoming Multicultural Environment : be a part of a dynamic, global team and thrive in an inclusive and supportive work environment with open communication and regular team-building company social events.
  • Social Sustainability Values : join our sustainable business practices focused on five pillars, including IT education, community empowerment, fair operating practices, environmental sustainability, and gender equality.
