About Share Share is a venture-backed startup building the global marketplace for bandwidth. We enable anyone to build their own programmable internet network, in seconds. Only the largest tech companies have escaped this, by spending billions to build their own physical networks. Senior Network Developer Infrastructure providers sell their services in the Share Marketplace; giving builders, AI agents and enterprises the ability to build their own global backbone via an API layer. The path, the performance, how long they need it and paying only for what they use. The Role Our network is the foundation of the product. Every route a customer provisions through our API has to exist, perform and stay up on real hardware. We're hiring a Senior Network Developer to design and build that network as software: a distributed, multi-provider fabric that engineers change through code, not by logging into devices. You'll own the network architecture end to end. That covers our BGP edge (transit, peering at KIXP and LINX, private interconnects with hyperscalers), the backbone, and the PoPs and data centers we're adding across the continent. You'll set the standards our network is built to, which partner ISPs connecting to us will inherit. As we grow, you'll also help build the network engineering team.

What You'll Do
Design the backbone and PoP architecture as standard, repeatable building blocks, from edge to data center, so we can add capacity and new markets without redesigning each time. Build on disaggregated white-box hardware (Edgecore with IP Infusion OcNOS today), and make the hardware and software calls that keep us fast and affordable. Turn operations into software. That means a source of truth (Nautobot),



templated config (Jinja), and CI/CD with validation, staged rollouts and rollback for every change. Build the telemetry and observability that show what the network is really doing. Use AI where it actually helps: anomaly detection, automated triage, and auto-remediation with a human in the loop. Work with our software team on the API and provisioning layer that exposes the network to customers, and with partner ISPs' engineers on the hand-off. Our Idóneo Candidate 8+ years building and operating large networks at a hyperscaler, CDN, internet exchange, carrier or ISP. Deep BGP at scale: route policy, communities, RPKI, traffic engineering, peering and transit. Strong data center and backbone design. Hands-on with white-box or disaggregated networking, including choosing hardware and knowing where the silicon limits you. You treat the network as code. You write automation yourself (Python or similar), and you've built or run the pipelines, source of truth and telemetry that make that safe. You've owned availability for something that couldn't go down, and can walk us through a real incident: what broke, how you found it, and what you changed. You bring ideas, not tickets, and you want to help build a team, not just a network. Nice to have Experience at an internet exchange, or running peering at scale. Open networking stacks like SONiC, OcNOS or FRR, or contributions to them. Streaming telemetry (gNMI/gRPC, sFlow), and building your own monitoring tooling. 400G/800G and optical (ZR) deployments, including vendor selection and certification. Access networks (GPON/XGS-PON) and MikroTik or Huawei gear, since many partner ISPs run it. Building networks in emerging markets such as Africa or Latin America.
