What you'll do

Own the end-to-end design of how systems connect and communicate: topology, links, transports, delivery semantics and failure behaviour
Design connectivity scenarios such as beyond-line-of-sight operation over LEO satellite or cellular links, including latency budget, link selection and failover, security, and behaviour when the link drops
Build the network: addressing plans, routing, segmentation and multi-homing across tactical radio, cellular, satcom and wired links, with dynamic routing and link selection
Build secure links: IPsec/IKEv2 or WireGuard overlays with certificate authentication from hardware-backed keys, including rekeying, NAT traversal and behaviour on link loss
Design how trust propagates from production to the field: device identity, certificate lifecycle, mutual authentication, authorisation tiers, revocation and signed commands that work without backend connectivity
Design and build the node agent that runs on every node and exposes identity, health, software state, connectivity and updates through one API
Define one resource model for every node type, versioned and backward compatible, with SDKs generated from the contract
Design node discovery with and without infrastructure, and a directory that survives restarts and shows what should exist versus what is present at fleet scale
Build on proven middleware and transports, define delivery semantics per traffic class, and engineer QoS so command and control traffic survives congestion
Treat network as code: configuration templated, version controlled, validated in CI and shipped as part of the system release
Verification: network emulation reproducing measured field link profiles, fault injection in CI, and network test campaigns at test ranges and flight tests with root cause from packet captures
Write design documents and contracts that embedded, backend and application engineers build against, and review designs

What we're looking for

Degree in Computer Science, Electrical Engineering, Telecommunications or a related field, or equivalent experience
5+ years building networked or distributed systems in production, combining software engineering with hands-on network engineering, including technical ownership of a core component other teams depend on
Designed a networked system end to end and can reason through a new connectivity scenario from first principles: topology, latency budget, failure modes and security
Expert in Rust, Go or C++, working proficiency in Python, and comfortable reading and writing C++
Strong networking across the stack: IP addressing and routing, UDP, TCP and QUIC internals, congestion control, multicast, NAT traversal, MTU and fragmentation; fluent with Wireshark and tcpdump
Expert Linux networking: iproute2, policy routing, network namespaces, VRFs, bridges, VLANs, nftables, tc and netem
Production experience with IPsec (strongSwan or libreswan) and WireGuard, including PKI-based authentication
Routing: OSPF and BGP (ideally FRRouting or BIRD), and how latency, loss and link quality shape routing and protocol design in dynamic networks
Applied security: PKI and certificate lifecycle, mTLS, hardware-backed keys (TPM or secure elements) and authorisation models
Built services that run on devices: Linux daemons, systemd, local IPC and resource-constrained environments
Experience with middleware such as DDS, ROS 2, Zenoh, ZeroMQ, NATS or gRPC, including discovery, flow control, serialisation and QoS
API and contract design consumed by many teams: schema evolution, versioning and backward compatibility
Written design documents that other teams implemented against
Willingness to travel to test sites and flight tests (around 20%)

Nice to have

Systems built for denied, degraded, intermittent or limited (DDIL) connectivity: defense, robotic fleets, autonomous vehicles, space
Beyond-line-of-sight operation over LEO satellite, cellular or long-range radio links
Integration of MANET or mesh radios (e.g. Silvus, Doodle Labs, Persistent Systems) and MANET routing such as OLSR or B.A.T.M.A.N.
Network emulation with EMANE, CORE, ns-3 or Linux netem
Time synchronisation with PTP/gPTP
Replication and coordination (Raft, gossip, CRDTs, logical clocks)
Embedded ARM targets, RTOS or mixed Linux and RTOS systems
Tactical datalinks, defense crypto equipment or interoperability standards such as STANAG 4586
