Most networks are designed for environments where connectivity is reliable, bandwidth is abundant, and failure is the exception.
You will be designing and building networks that operate across moving nodes, multiple bearer types, and degraded or denied links. Systems where topology changes in real time, where path selection has to happen automatically, and where the assumption is that links, nodes, and services will fail.
There is no existing architecture to maintain. Building multi-bearer link aggregation and path selection across LTE, satellite, and RF links. Implementing zero-trust connectivity at the edge: certificate-based device identity, mutual authentication, policy enforcement. Owning routing, traffic engineering, and QoS across constrained and adversarial links. Building observability into networks that are partly opaque by nature. Writing the automation and infrastructure-as-code that makes it repeatable and deployable.
You will also be shaping the architecture standards and reference patterns the wider engineering team builds against.
You should be genuinely comfortable at packet level in Linux. SD-WAN or software-defined networking applied to real operational problems, not vendor demos. If you have worked with MANET routing protocols (OLSR, BATMAN, OSPF-MDR) or disruption-tolerant networking approaches, that is directly relevant here. Zero-trust architecture experience matters: PKI, certificate lifecycle, identity-aware policy at the network edge. You should be comfortable writing the code that configures, validates, and deploys network infrastructure.
