Senior Network Architect: Global Backbone & Automation

Share; Barcelona; On-site; EUR 90,000 - 130,000; Full time

Job summary

Share is building the global marketplace for bandwidth. We are hiring a Senior Network Developer to design and build a distributed, multi-provider fabric that engineers change through code, not by logging into devices.

You will own architecture end-to-end, including BGP edge, backbone, PoPs and data centers, setting standards for partners to inherit. You will drive Segment Routing, IPv4/IPv6 coexistence, and work with edge hardware like Edgecore with OcNOS.

Qualifications

• 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. You know Clos/EVPN-VXLAN fabrics and MPLS or Segment Routing, and when each makes sense.
• 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.

Responsibilities

• 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.
• Drive our move to Segment Routing and a clean IP architecture, including IPv4 reuse, IPv6, and how customer and internal address space coexist.
• 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.
• Own availability. Limit how much any failure can affect, mitigate first and diagnose second, and turn post-mortems into fixes in the system.
• 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.
• Help hire and develop the engineers who’ll run this with you.
