Network Engineer - Edge Routing & Telemetry (Remote)

Network Engineer (Edge Routing & Telemetry) Location: Remote (U.S.) Team: Engineering • Full‑time • Pre‑seed About Hoplynk Hoplynk is building the communications and networking layer for the intelligent edge, ensuring resilient connectivity for autonomous systems and mission-critical operations in any environment. We’re a pre-seed startup spun out of Stanford University and based in San Francisco, developing an embedded software/firmware stack that delivers multipath, failure-aware networking across heterogeneous links so critical systems stay online when networks don’t. The Role You’ll be our first networking specialist and a founding engineer. Your mission: design, ship, and measure a robust multipath networking stack on Linux. You’ll own the edge data plane end-to-end, from kernel and policy to telemetry, experiments, and field support, to accelerate learning in the field and deliver weekly improvements. What You’ll Do and Own • Design, implement, and evolve the multipath routing/transport stack on Linux, including policy engines for path selection, subflow management, and failover. • Define and maintain SLOs for latency, loss, failover time, and goodput. • Build and operate telemetry: per-subflow RTT/RTTVAR, cwnd, loss/reordering, packet sampling, and device-health signals; keep schemas stable as the system grows. • Design and run experiments with simulated networks in QEMU. • Partner with embedded/firmware on BSP, drivers, OTA updates, and device observability. • Support deployments and onboarding: capture traces, triage issues, and harden release processes as we scale customers. What You’ll Bring • Clear writing and documentation; ability to mentor and set engineering standards. • Willingness to support field work: capture traces, debug issues, and harden releases. • Solid Linux networking experience at L3/L4 with iproute2 / netlink / tc. • A track record of improving latency, reliability, or throughput via shaping, queue management, or congestion control. • Comfort with transports and routing (TCP, QUIC, MPTCP, MPLS, routing daemons). • Experience building network telemetry (RTT, loss, cwnd, packet sampling) with stable data models. • Ability to design experiments, simulate real conditions, and measure results. Nice to Have • Routing & Fast-Path: FRR, Babel, OLSR, batman-adv; frameworks like DPDK; Segment Routing (SR-MPLS/SRv6). • Wireless & Cellular Networking: CGNAT, captive portals, flaky radios. • Embedded & Security: OpenWrt, Yocto, Buildroot; OTA frameworks (RAUC/Mender), A/B partitioning, secure boot/firmware signing. • Timing & Observability: NTP, PTP, perf, ftrace, pcap, mptcpd, gNMI/streaming telemetry. • Hardware & Applied Domains: Schematics interpretation, PHY bring-up testing; robotics/autonomy networks in challenging RF environments. Tools & Tech You’ll Touch Linux 6.x · MPTCP · OpenWrt/Debian/Ubuntu · iproute2/netlink · mptcpd · perf/ftrace · Rust / C++ / Python (routing and full-stack development) How We Work - Hoplynk’s Values We believe that shared values are the foundation for success. At Hoplynk, we value: • Candor: Say the hard thing kindly, early, and with evidence. Speak up during decisions. • Humility: Strong opinions, loosely held. Change your mind with facts. Teach and learn in the open; celebrate team wins over heroics. • Initiative: Run toward the smoke. Own problems end-to-end. Ship in small, safe steps with clear, observable outcomes.
