• Leading end-to-end solution blueprints spanning access network, transport, core, IMS/application layer, dispatch and recording systems, device ecosystems, and integration interfaces.
• Driving vendor selection, solution validation, and deployment governance, including HLD/LLD documentation, integration planning, cutover strategies, and acceptance testing.
• Defining resilience architecture encompassing geo-redundancy, active-active/active-standby configurations, disaster recovery strategy, backup and restore, and observability frameworks.
• Establishing security-by-design principles and compliance guardrails for MCX services, covering encryption, identity management, key management, and auditability.
• Supporting the test team through ATP phases, defect qualification, and FAT/SAT readiness activities.
• Leading technical workshops with key stakeholders, translating complex operational requirements into technical designs and structured delivery backlogs.

• Proven track record delivering mission-critical platform design and deployment across MCX, PS-LTE, or critical communications environments, with 15+ years of relevant experience.
• Hands-on experience with vendors such as Hytera, Airbus, Motorola Solutions, or TDTech.
• Strong knowledge of 3GPP Mission Critical Services, IMS, VoLTE/VoNR, QoS/QCI/5QI, policy control, and session management.
• Demonstrated ability to produce HLD/LLD documentation, test strategies, and operational readiness artifacts, with experience managing multi-vendor technical delivery programs.
• Strong leadership and stakeholder engagement skills, with the ability to bring together cross-functional teams, drive alignment, and communicate technical strategies clearly at all levels.
