• Conduct network design reviews and simulations to validate redundancy and performance.
• Integrate MCX applications with public safety systems and dispatch platforms.
• Coordinate testing and validation of end-to-end mission-critical use cases.
• Ensure compliance with public safety security standards and 3GPP MCX requirements.
• Collaborate with transport and RAN teams to ensure low latency and QoS.
• Lead technical troubleshooting during field trials and commercial launch.
• Document architecture, configurations, and integration test results.

Qualifications:

Education:

• Bachelor’s degree in Network Engineering or Telecommunications.

Experience:

• 6+ years in core engineering with 3+ years in mission-critical systems.

Skills:

• Deep knowledge of MCPTT, EPC, IMS, LTE/5G architecture, end-to-end QoS, high-availability systems.
