About Share

Share is a venture-backed internet infrastructure network building Africa's backbone. The company aggregates underutilized telecom infrastructure, fiber, subsea cables, and data centers, and provides ISPs with scalable access to bandwidth without traditional upfront costs. Share's network spans thousands of kilometers of fiber, 12 infrastructure providers, and 10 data centers, reaching over 8 million people across East Africa.

At the network level, Share operates a RADIUS proxy architecture that authenticates ISP subscribers, provisions their internet access, and coordinates with partner BNG (Broadband Network Gateway) equipment. The platform must coexist with existing ISP infrastructure, not replace it. This means every deployment involves real BNG configuration, real RADIUS authentication, and real subscriber traffic.

The role

We are hiring a VP of Systems Engineering to build, own and lead Share's network-facing infrastructure: the FreeRADIUS proxy servers that authenticate ISP subscribers,



the provisioning pipeline that pushes credentials and plan attributes to per-partner RADIUS servers, the BNG integration layer, and the deployment and monitoring of all systems infrastructure. You will work directly with the network team (who handle ISP-side BNG configuration) and the software team (who build the APIs that drive provisioning).

This is a player-coach role. You are hands-on today; you will configure FreeRADIUS servers, write deployment scripts, troubleshoot authentication failures on production networks, and design the infrastructure that scales from 10 ISP clients to 500. And as Share grows, you will hire and lead the systems engineering team, set the technical standard they work to, and own the roadmap for how our infrastructure is built and run. You are the person the team calls when a subscriber can't authenticate or when a new ISP's BNG doesn't behave as expected — and the person who decides how we solve it at scale.
