We are building a custom high-load and high-scale IPsec backend on AWS to support over 20,000 IKEv2 tunnels for connected vehicles with dual-modem WAN bonding and custom StrongSwan gateways, IPv6-only. We are looking for an experienced network engineer with
software development skills to help us create this platform.
- Implementing redirector and tunnel-terminator logic for thousands of parallel IKEv2/IPsec tunnels. Designing control-plane logic that can steer per-vehicle traffic over dual-modem tunnels with dynamic source IPs.
- Embedding client identity into the protocol stack
- Writing automation around Linux networking (iptables/netfilter/XFRM), StrongSwan VICI, and AWS primitives (NLB, ENI, etc.). Writing plugins or extensions for StrongSwan or the Linux IPsec stack if needed.
- Building observability and traceability for IPsec sessions at scale (IDi, DPD status, per-modem metrics). Debugging packet flows and helping design testable redirect and failover scenarios.
MUST
- Deep understanding of the Linux networking stack, including iptables, XFRM/IPsec, netfilter, and conntrack.
- Experience configuring StrongSwan (IKEv2, CHILD_SA lifecycles, MOBIKE, VICI).
- Solid AWS knowledge at the level of the Advanced Networking Specialty certification or equivalent real-world experience. Able to reason about flow consistency through NLB, GWLB, and EC2 fleet mechanics.
- Capable of developing code.
- Comfortable reading packet traces (tcpdump, Wireshark) and analyzing kernel-level behavior.
- Experience with building custom VPN plugins (e.g., for StrongSwan, Libreswan, or similar).
- Kernel-space or eBPF experience.
- Previous work on mobility protocols or embedded network stacks.
- Familiarity with QNX or automotive telematics protocols.
- Hands-on experience with VPP, DPDK, or packet reordering logic.
- IPv6 edge deployment experience.
- AWS Advanced Networking Specialty certification.
