Share

Role Description The global marketplace for bandwidth. Share aggregates telco infrastructure into a single intelligence layer, giving ISPs, hyperscalers, and AI companies a seamless path to deliver connectivity into every home and business. We're hiring a VP of Network Engineering to lead the function that makes this real. This is the senior-most networking role at Share, reporting directly to the founders. You will own the entire technical estate (backbone, aggregation, access, peering, the systems they depend on, and the partner integrations they touch) and the team that builds and runs it. This is a role for someone who wants to create, not just operate. The mandate is to design the protocols, define the standards, and develop the reference architectures that an entire ecosystem of partner ISPs will inherit from us, and to leverage AI across the operational surface so the network behaves more like a system that thinks than a stack of boxes that's been configured. The expectation is still hands-on. You'll set technical direction, run a small high-leverage engineering team, and stay close enough to the metal that you can sit on a BGP debug call at 2am and not be the bottleneck. This is also a deeply partner-facing role: you'll absorb partner ISPs into our platform and push each one past whatever ceiling they walked in with. Qualifications - Senior leadership experience inside an ISP, carrier, or comparable network operator. - A real track record of building or leading network engineering teams. - Deep BGP knowledge. - MPLS in production at scale. - Real operational experience with passive optical access. - Comfortable in disaggregated, white-box environments. - Hands-on with MikroTik and Huawei. - Fluent in L2/L3 fundamentals. - Comfortable driving troubleshooting end-to-end. - Partner- and customer-facing maturity. - A bias for execution. - Based in Kenya, or ready to relocate. Requirements - Own the strategy for our BGP edge. - Own the policy posture. - Direct MPLS in the backbone. - Negotiate and establish new peering arrangements. - Own the disaggregated, white-box switching strategy. - Direct L2/L3 aggregation and BNG strategy. - Own passive optical access and the fiber plant itself. - Partner with the Systems team on the AAA stack. - Own the network-layer services the AAA plane depends on. - Hire, develop, and lead the network engineering team. - Build a team that writes things down. - Run a team that's allergic to ticket-shuffling and bureaucracy. - Lead the technical relationship with our partner ISPs. - Own PoP and backbone reliability end-to-end. Benefits - The senior networking seat at the table while we build the technical backbone of Africa's next-generation internet. - Real ownership of strategy, architecture, and execution. - Executive-level compensation: competitive salary and meaningful equity. - Private health and wellness benefits. - A high-ownership environment with a steep but well-supported learning curve.

Role Description We are hiring a Founding Software Engineer to take ownership of the platform’s most critical technical domains: - The payments pipeline (collections, revenue splitting, treasury operations) - The billing engine (subscription lifecycle, cycle management, automated renewals) - The integration layer (BSS/OSS sync with partner systems) You will work directly with the CTO and a small team of engineers to ship production systems that handle real financial transactions for real ISP partners. Qualifications - 7+ years of professional software engineering experience, with at least 3 years in backend systems handling real financial transactions (payments, billing, ledger, or treasury) - Deep TypeScript/Node.js expertise. You should be able to design a NestJS microservice from scratch, not just work in one. - Production experience with payment gateway integrations (M-Pesa, Stripe, Adyen, or similar). You understand STK push flows, webhook idempotency, callback signature verification, and reconciliation. - Strong PostgreSQL skills. You can design schemas for financial data, write migrations, and reason about transaction isolation and locking. - Experience with event-driven architectures (Kafka, RabbitMQ, or similar). You understand the difference between request-reply and fire-and-forget patterns and when to use each. - You ship. You can take a spec document and turn it into production code without waiting for someone to break it into small tasks. - AI-augmented engineering (required mindset) Requirements - You already use AI coding assistants (Claude, Cursor, Copilot, or similar) daily and can articulate how they change your workflow. - You are comfortable working with AI-generated specifications and can critically evaluate them, push back where they are wrong, and extend them where they are incomplete. - You see AI as a force multiplier that lets a small team operate at the capacity of a much larger one. You are not threatened by it; you are faster because of it. - You are willing to contribute to improving our AI-assisted workflows — better prompts, better context files, better session structures. Benefits - Competitive Salary & Equity package - Paid Business Travel when needed - Ownership in a venture-backed early stage startup building the future of physical and digital infrastructure in Africa
