Note: The job is a remote job and is open to candidates in USA. CentralSquare Technologies is a company dedicated to empowering public servants with innovative technology. They are seeking a Principal Network Systems Architect for NG911 to design and implement network architectures that ensure reliable and secure communication systems for public safety. This role involves leading the technical architecture and deployment of NG911 network solutions, collaborating with product managers, and ensuring compliance with industry standards.

Responsibilities

• Design and own end-to-end NG911 network architectures aligned to NENA i3 standards, ESInet integration, and state-level requirements
• Define architectures for SIP/VoIP call routing, redundancy, failover, and high availability (targeting 99.999% uptime)
• Develop scalable patterns for PSAP-to-cloud connectivity, including VPN, AWS Transit Gateway, and Direct Connect
• Ensure architectures support integrated NG911 services (voice, text-to-911, ALI/location data, video)
• Design and implement AWS-based network architectures (VPCs, Transit Gateway, NLB, WAF, VPN, Direct Connect)
• Build and maintain hybrid network topologies connecting PSAPs, ESInet providers, and cloud infrastructure
• Ensure resiliency across multi-AZ and multi-region deployments
• Define and enforce Infrastructure-as-Code (IaC) standards for repeatable deployments
• Architect and support telephony platforms (SIP trunks, SBCs, media gateways, and PBX layers)
• Ensure proper integration between ESInet SIP trunks, PSAP phones/workstations, and cloud-hosted PBX layers
• Design call routing flows, failover models, and redundancy patterns
• Support migration paths from legacy (TDM/PRI/analog) to SIP-based NG911 architectures
• Personally lead hands-on deployment of network architectures for the most complex and highest-risk PSAP environments
• Build and continuously refine the deployment runbooks, playbooks, and standards that enable Cloud, Services, and Support to execute routine go-lives without this role in the loop — eliminating single-person dependency for a five-nines service
• Coordinate across customer IT teams, ESInet providers, and cloud engineering
• Validate connectivity (TGW/VPN), SIP call flows, and end-to-end call-handling readiness prior to go-live
• Design for and enforce 99.999% availability (five nines) and sub-150ms latency for real-time communications
• Implement network security aligned to CJIS, NIST, and CISA frameworks
• Ensure compliance with state NG911 mandates and ESInet requirements
• Own (or design out) the incident-response and on-call posture required to sustain five-nines
• Evaluate, integrate, and manage last-mile and connectivity partners (e.g., ESInet providers, PEAKE, Dejero) against architecture, reliability, and cost requirements
• Serve as the technical point of contact in partner architecture and integration discussions
• Serve as the technical authority for NG911 network architecture internally and externally
• Lead technical discussions with state 911 agencies, ESInet providers, and strategic partners
• Translate operational PSAP requirements into clear technical architecture designs
• Partner with the NG911 Product Manager to turn roadmap and priorities into executable architecture

Skills

• 10+ years in network engineering, architecture, or telecom infrastructure, including principal/lead-level scope
• Hands-on AWS network architecture in production and deep SIP/VoIP/telephony (SBC, media gateways, call routing)
• Strong IP networking foundation (routing, switching, VPNs, QoS)
• Proven experience with high-availability, mission-critical systems
• NG911 architecture and ESInet environments
• NENA i3 standards and SIP-based call routing
• Strong system-level thinking across network + cloud + telephony integration
• Owns both design and hands-on execution, durably — this is not a step toward management
• Credible across the table from state 911 directors and ESInet partners
• Operates calmly in high-stakes, mission-critical environments
• Excellent communication with both technical teams and public safety stakeholders
• A required part of the onboarding process for this role involves obtaining CJIS (Criminal Justice Information Services) clearance—a critical credential for safeguarding public safety data
• Familiarity with public safety systems (CAD, ALI, 911 call handling)
• AWS Certified Advanced Networking – Specialty (or AWS Solutions Architect)
• CCNP or CCIE (or equivalent)
• NENA ENP (domain credibility)
• Working knowledge of CJIS, NIST, and related compliance frameworks

Benefits

• Mentorship, learning programs, and clear paths for advancement
• Competitive compensation and a benefits package designed to support your life inside and outside of work—tuition reimbursement, parental leave, paid volunteer hours, and unlimited PTO
• Flexible work environment gives you the freedom to balance your heroic work with personal well-being, whether you’re in the office or remote
• CJIS (Criminal Justice Information Services) clearance support including comprehensive background check and assistance to secure this clearance
