Job Summary 

Thoro is seeking an Embedded Cloud Software Engineer to build the high-performance C services that live on the robot and connect it to the cloud. You will own how the robot ingests commands, manages state, and offloads telemetry using our high-performance robotics toolkit.

Working at the seam between the robot and the cloud, this role designs and implements the secure, bidirectional communication paths that keep our fleet coordinated, observable, and safely updatable in the field. You will collaborate closely with platform, cloud, and autonomy engineers to deliver services that are robust under the constraints of real-world industrial environments.

• Integrate on-robot logic with AWS IoT Core for secure, bidirectional communication
• Design and implement distributed algorithms for multi-robot operation and synchronization
• Build and maintain resilient networking layers over MQTT, WebSockets, and TCP/UDP
• Optimize on-robot services for performance, memory footprint, and reliability in resource-constrained environments
• Collaborate with platform and cloud teams to define APIs and data contracts between the robot and the cloud
• Troubleshoot field issues with the fleet and deliver timely fixes
• Contribute to code reviews, documentation, and engineering standards
• Present technical designs and results to engineering leadership and cross-functional partners

Required Skills / Abilities: 

Our ideal candidate will have experience with the following:

• Expert-level C and experience with asynchronous programming and event loops
• Deep understanding of networking protocols, including MQTT, WebSockets, and TCP/UDP
• Experience with Linux IPC and multi-threading in a resource-constrained environment
• Strong problem-solving and debugging skills across the application and system layers
• Ability to work independently and in a team environment
