Chief Technology Officer at Green Telecom Tanzania

We are looking for a visionary and hands-on Chief Technology Officer (CTO) to lead Green Telecom’s technology function. The CTO will be instrumental in shaping and delivering our ISP infrastructure strategy from core network design to rural last-mile deployment ensuring high availability, low latency, and robust scalability.

This role requires deep expertise in ISP architecture, strong leadership in cross-functional teams, and the ability to align technical capabilities with business growth goals.

Key Responsibilities

Technology Strategy & Innovation

• Lead the development and execution of the company’s technology roadmap.
• Introduce scalable, cost-effective, and innovative solutions to improve service delivery and customer experience.
• Champion the adoption of best practices in network security, architecture, monitoring, and performance optimization.

ISP Infrastructure Leadership

• Architect and oversee the implementation of end-to-end ISP infrastructure, including:
• Core network infrastructure: IP/MPLS design, routing (BGP, OSPF), peering, and transit arrangements.
• Transport/backhaul networks: Fiber, microwave, and wireless backhaul systems; understanding of SDH, DWDM, and Ethernet-based transport.
• Access networks: FTTH, fixed wireless access (FWA), GPON, and hybrid solutions for rural deployments using aerial wooden poles.
• Redundancy and resilience: Design for high availability, failover routing, and traffic engineering to support QoS.
• Network management systems: NMS/OSS platforms, SNMP monitoring, and centralized provisioning.
• Customer edge & last mile: Configuration of CPEs, OLTs, ONU/ONTs, wireless CPEs, and support for IPv6.
• Lead infrastructure rollouts in greenfield areas, including network planning, topology mapping, pole route design, and power systems integration (solar/hybrid).

Operational Excellence

• Oversee 24/7 NOC operations to ensure uptime, fault response, and SLA adherence.
• Implement capacity planning frameworks, incident response playbooks, and proactive maintenance schedules.
• Standardize network documentation, configuration management, and version control practices.

Team & Talent Development

• Recruit, mentor, and lead a multidisciplinary technical team (network engineers, infrastructure planners, systems admins).
• Set performance goals, track KPIs, and invest in continuous learning and professional certification for technical staff.
• Foster a high-performance engineering culture with strong cross-team collaboration.

Cross-functional Collaboration

• Work closely with the COO, VP of Network Services, and the CTO's direct reports to align infrastructure with commercial growth plans.
• Partner with Finance and Procurement to optimize capex/opex for network expansion.
• Collaborate with regulatory bodies (e.g., TCRA) on compliance, spectrum use, and licensing.

Requirements

Experience & Expertise

• 10+ years of experience in ISP/telco network engineering or infrastructure leadership, including 5+ years in a senior or CTO-level role.
• Proven track record in designing, deploying, and managing:
• Layer 2/3 networks (VLANs, bridging, OSPF/BGP/MPLS)
• ISP backhaul architecture (ring/star topologies, route optimization)
• Core services (DNS, DHCP, RADIUS, PPPoE, CGNAT)
• Rural and semi-urban deployments with a focus on infrastructure constraints
• Familiarity with regulatory requirements, IP address management (RIPE/AfriNIC), and peering policies.

Education & Certification

• Bachelor’s or Master’s degree in Telecommunications, Electrical/Electronic Engineering, Computer Science, or a related field.
• Professional certifications such as CCNP/CCIE, JNCIP, MikroTik MTCINE, Ubiquiti UEWA, or equivalent are highly desirable.
