Experience designing and supporting secure, fault-tolerant, and scalable solutions
Excellent stakeholder management and communication skills, with the ability to engage across technical and non-technical audiences
Exposure to 4G/5G networks and data analytics is highly desirable
Relevant qualifications in Computer Science or Engineering, with cybersecurity certifications (e.g. CISSP, CISM) advantageous
