2 days ago
Join Hoplynk as the senior networking lead and a founding engineer. Your mission: set the architecture and deliver a production?grade multipath networking stack on Linux.
The RoleYoull drive the technical roadmap from kernel and policy management to observability and QoS optimization; mentor the team; and turn user feedback into measurable improvements.
What Youll Do And Own- Define the end?to?end system architecture, including routing/transport policies, subflow management, and failover.
- Establish SLOs (latency, loss, failover time, goodput) and build comprehensive monitoring systems.
- Lead design reviews, RFCs, and implementation plans across kernel/user space (iproute2, netlink, tc, eBPF/XDP, mptcpd).
- Design and run experiments with QEMU and other network simulation services.
- Partner with our embedded systems team on BSP, drivers, OTA/rollback, and device observability.
- Support deployments: capture traces, triage issues across layers, tune policies, and manage the release process as we scale customers.
- Mentor engineers, raise standards for documentation and reliability, and help hire the early networking team.
- Routing & Policy: Strong familiarity with writing low level code in Rust; familiarity with queue management and load balancing optimization algorithms; deep knowledge of Linux routing stacks and familiarity with DPDK, eBPF, or custom datapath acceleration.
- Transport & Multipath: Strong understanding of TCP, QUIC/MP?QUIC, and MPTCP protocols; ability to prototype, simulate, and validate transport behavior under real?world conditions.
- Telemetry & Observability: Hands?on experience with network instrumentation and metrics; experience with perf, ftrace, and streaming telemetry pipelines.
- Leadership & Collaboration: Mentorship, clear documentation, and ability to bridge firmware, kernel, and cloud domains.
- Embedded & Security: Experience with OpenWrt, Yocto, or Buildroot environments; familiarity with OTA frameworks, A/B partitioning, secure boot.
- Familiarity with cellular modems, multi?SIM bonding, and adaptive path selection across ISPs for latency and privacy.
- Awareness of traffic fingerprinting and obfuscation techniques; experience designing overlay networks or tunnel obfuscation layers.
- Strong understanding of network encryption, key management, and secure channel establishment.
- Ability to interpret hardware schematics, understand PHY bring?up, or debug low?level Ethernet/Wi?Fi/5G link issues.
- Experience deploying communications or networking systems in robotics, autonomy, or rugged edge environments where RF and multipath conditions vary drastically.
Linux 6.x, MPTCP, OpenWrt/Debian/Ubuntu, iproute2/netlink, mptcpd, perf/ftrace, Rust/C++/Python.
How We Work - Hoplynks Values- Candor: Say the hard thing kindly, early, and with evidence.
- Humility: Strong opinions, loosely held. Teach and learn in the open.
- Initiative: Run toward the smoke. Own problems end?to?end.
