Senior Systems Engineer - Network

About the Team

The Core team builds and owns the C++ infrastructure that NEO's entire stack runs on - sensor pipelines, motor control interfaces, networking, inter-process communication, and the foundational libraries that ship on every robot. Our code runs thousands of times per second on hardware moving through the real world, and its correctness and performance directly determine what every other team can build and ship. If you want to work on the systems layer that makes physical AI possible at scale, this is that team.

Your Charter

Own the design and execution of all networking systems on the core robot, working with our Cloud Infra and Apps teams to ensure we can scale robot operations end-to-end from fleet management to real-time VR teleop. This is critical-path work: as 1X scales from hundreds to tens of thousands of robots, the reliability, performance, and simplicity of networking is a critical piece of successful deployments. You will lead architecture decisions, build core components, and set technical standards for the team.

Key Outcomes:

• Own the core networking systems for robots and design topologies that maximize QoS for peer-to-peer, peer-to-server, and one-to-many.
• Design and implement load balancing strategies that maximize network utilization.
• Manage seamless connectivity across multiple networks (eg wifi, 5G)
• Build APIs & protocols that transmit multi-model data at scale, including high-bandwidth video

Key Competencies:

• Deep understanding of network topology design for peer-to-peer, peer-to-server, and one-to-many multicast
• Load balancing and resource management on both client and server
• Experience architecting systems that support network transitions and degraded connectivity
• Protocol design for high-bandwidth high-QoS multimodal payloads
• End-to-end system thinking across hardware, embedded, network stack, and cloud including QoS design (e.g. traffic classes, scheduling, and budgeting).
• Congestion control and bandwidth estimation for building an adaptive realtime stack.

Measurement discipline: realistic network emulation, tail-latency analysis, and cross-host timings (PTP/NTP).

Minimum Requirements:

• 6+ years in network engineering, distributed systems, or related cloud infrastructure roles
• Proven experience shipping network systems in production at large scale
• Strong experience with network fundamentals including TCP/IP, UDP, and related video/audio protocols
• Experience with wireless network (wifi/5G) in mobile or embedded systems
• Shipping a realtime system over variable-bandwidth links.
• Proficient in C++

Preferred Skills:

• Experience in robotics, autonomous vehicles, drones, or other embedded realtime systems
• Experience with video transport protocols such as WebRTC or MoQ.
• Experience with edge computing or hybrid cloud/edge networking
• Experience with multi-radio systems
