Senior Member of Technical Staff: Realtime Networking
Walden Robotics · Cambridge, MA · 2 mo ago
EngineeringFull-time
You will own the networking that our robots depend on—most critically the low-latency wireless link that carries teleoperation between operator and robot, and more broadly the on-robot, building-wide, and infrastructure networking that keeps a deployed fleet connected and responsive. Teleoperation lives or dies on this link: it must deliver video, audio, and control with minimal latency and maximum reliability across real, messy industrial RF environments.
Responsibilities
- Teleop Network Link: Own the low-latency wireless link between operator and robot—topology, radio selection and configuration, and relentless optimization of latency, jitter, and reliability.
- Real-Time Transport: Design and tune the transport and streaming software (WebRTC and similar) that carries control, video, and audio, making the right tradeoffs between latency, throughput, and robustness.
- Building-Wide Infrastructure Design: Design and deploy the network infrastructure across customer and deployment sites—access point placement and coverage planning, backhaul, VLANs/segmentation, and the physical and logical topology that keeps a facility's robots reliably connected.
- Robot & Infrastructure Networking: Architect and maintain networking on the robot and across deployment sites—wireless infrastructure, connectivity, and the configuration that keeps robots reliably online.
- RF & Environment Robustness: Characterize and improve performance in real industrial RF environments, handling interference, roaming, coverage, and spectrum challenges.
- Resilience & Failover: Ensure networking degrades gracefully and recovers cleanly under loss, congestion, or coverage gaps, in coordination with the teleop and safety systems.
- Diagnostics & Tooling: Build tools to measure, monitor, and debug network performance in the lab and in the field.
- Cross-Functional Collaboration: Partner with teleoperation, VR, and infrastructure engineers to define interfaces and hit end-to-end latency and reliability targets.
Requirements
- Real-Time Networking Expertise: Proven experience building low-latency, real-time networked systems where latency and reliability are critical.
- Networking Fundamentals: Deep understanding of networking across the stack—IP, transport protocols, routing, QoS, and the causes of latency and jitter.
- Wireless Understanding: Solid working knowledge of wireless networking (Wi-Fi and related technologies) and the realities of RF in real environments, even if your primary strength is software.
- Real-Time Media/Transport: Hands-on experience with real-time streaming or transport protocols such as WebRTC, RTP, or custom low-latency transports.
- Systems Software: Strong C/C++ and/or Python skills, with experience implementing and debugging networked software on Linux.
- Field Debugging: Strong ability to diagnose network problems across software and wireless boundaries using packet capture, network analysis, and RF tooling.
- Ownership: Track record of taking networked systems from design through deployment and real-world validation.
Preferred Qualifications
- Hands-on experience with industrial or point-to-point wireless systems (e.g., URWB), Wi-Fi 6/6E, or managed cellular connectivity.
- Experience designing building-wide or site-wide network infrastructure (coverage planning, structured cabling/backhaul, enterprise AP deployments).
- Experience with antenna selection, placement, and RF planning for reliable coverage.
- Familiarity with teleoperation, remote driving, or other latency-critical human-in-the-loop systems.
- Experience with network QoS, traffic shaping, and prioritization for mixed real-time traffic.
- Exposure to time synchronization, DDS, or other real-time middleware.
Benefits
- Competitive total compensation program, including salary, annual cash bonus, and company equity.
- Company-subsidized insurance programs.
- 401(k) with company match.
- Flexible PTO.
- Daily lunch.
