VP of Systems Engineer

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.

This role sits at the intersection of network engineering and systems engineering. You will own Share's systems function end to end — the infrastructure that makes internet access work for our partner ISPs, and the team you'll build to run it as we scale.

We are hiring a VP of Systems Engineering to build, own and lead Share's network-facing infrastructure: the Free RADIUS 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 Free RADIUS 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.

• Free RADIUS proxy architecture: Share operates a central RADIUS proxy that routes authentication requests to per-partner Free RADIUS servers. The proxy uses a failover mechanism (soft reject → attribute clearing → failover to partner pool) to determine whether a subscriber is Share-managed or partner-managed. You will own the configuration, deployment, monitoring, and scaling of this architecture.

• Per-partner Free RADIUS servers: Each ISP partner gets a dedicated Free RADIUS instance with a Hono API overlay for programmatic CRUD of subscriber credentials and plan attributes. You will manage these instances, their database backends, and their API endpoints.

• BNG integration support: Work with the network team to define and validate the BNG-side configuration changes required for each ISP partner (RADIUS pointer, Share-specific subnet, source-based routing, pool configuration). You are the bridge between the software platform and the ISP's physical infrastructure.

• Provisioning pipeline: The software platform's Provisioning service pushes subscriber credentials and plan attributes to Free RADIUS. You own the receiving end — ensuring the Free RADIUS API, database, and RADIUS configuration are correct and performant.

• Infrastructure and deployment: Server provisioning, deployment automation, monitoring, logging, and security for all systems infrastructure. Git Hub Actions pipelines, SSH-based deployments, VM management.

• CoA (Change of Authorization): Design and implement the CoA endpoint on per-partner Free RADIUS servers for real-time plan changes and session disconnects without re-authentication.

• Team and technical leadership: Set the standards, runbooks, and architecture for Share's systems function. Hire, mentor, and lead the systems engineering team as we scale, and represent systems engineering in technical and cross-functional decisions.
