Job Summary

Network Engineer

As part of our engineering team, you will be responsible for implementing custom network protocols, optimizing transmission over constrained or lossy networks, and ensuring reliable, high-speed communication for mission-critical robotic operations. The ideal candidate is hands-on with C/C++ and Python socket programming, understands the nuances of UDP communication, and has a proven track record in debugging, performance tuning, and network reliability strategies.

Key Responsibilities

1. Develop and maintain UDP-based communication systems between the Ground Control Station (GCS) and robotic platforms, supporting both command/control and high-throughput data like camera feeds.
2. Implement custom packet structures and ensure efficient serialization/deserialization for real-time data.
3. Ensure low-latency, high-reliability transmission over potentially lossy or constrained networks.
4. Analyze network paths to identify bottlenecks or failure points using tools like Wireshark or tcpdump.
5. Write robust code in both Python and C/C++, depending on performance or system integration needs.
6. Implement optional enhancements like heartbeat mechanisms, packet loss detection, or buffer control to improve communication reliability.
7. Write production-grade code in C/C++ and Python for networking and integration with robotics systems.

Must have Skills

1. Strong experience in UDP socket programming in C/C++ and Python on Unix-based systems.
2. In-depth knowledge of network fundamentals, including MTU, jitter, packet fragmentation, and latency management.
3. Familiarity with multithreading or asynchronous event-driven architectures (select, poll, async IO).
4. Proficient with network profiling/debugging tools and performance optimization techniques.

Preferred Skills

1. Real-time video streaming experience over UDP (custom RTP protocols, MJPEG/H.264 over UDP).
2. Exposure to robotic control systems or embedded Linux platforms.
3. Protocol design experience (sequence numbers, ACK/NACK, packet prioritization).
4. Experience with low-latency systems with strict performance requirements.

Desired candidate profile

1. Education Background:

   Bachelor’s degree in Computer Science or related field

2. Hands-on Experience:

   Minimum of 2 years working on network communication systems using C/C++ and Python in Unix/Linux environments.

3. Deep Understanding of UDP Protocols:

   Proven ability to work with unreliable datagram protocols and implement reliability mechanisms manually.

4. System-Level Thinking:

   Ability to analyze and optimize end-to-end communication pipelines, identify latency/failure points, and propose practical solutions.

5. Tool-Savvy:

   Comfortable using tools like Wireshark, tcpdump, and logging frameworks for diagnostics and performance tuning.

6. Adaptable Developer:

   Capable of switching between high-performance C/C++ and rapid-prototyping in Python based on system needs.

7. Real-Time Mindset:

   Prior experience or a strong inclination to work on time-sensitive systems with strict performance constraints.

8. Collaborative Yet Independent:

   Able to own complex tasks while coordinating with cross-functional teams (robotics, vision, control systems).

9. Bonus:

   Exposure to video streaming protocols, robotic control systems (especially UGVs), or embedded Linux development.
