Full-time
Remote
Mid LevelHoplynk is a pre-seed startup focused on building the communications and networking layer for the intelligent edge. The role involves designing and implementing a robust multipath networking stack on Linux, owning the edge data plane, and ensuring resilient connectivity for autonomous systems.
Transportation/Trucking/Railroad
Responsibilities
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
Qualification
Required
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
Preferred
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
