Embedded System Engineer

At Sentinel Eagle, the company builds autonomous UAV systems that operate where GPS and communications fail. Their systems integrate embedded Linux computers, flight controllers, cameras, sensors, networking, and custom electronics. The role focuses on solving complex system-level issues at the boundary of hardware, firmware, and operating systems, aiming to improve system reliability.

• Experience with embedded Linux systems and system integration on custom hardware.
• Strong debugging skills across hardware and software layers.
• Hands-on hardware prototyping or rework experience, including basic soldering.
• Familiarity with interfaces such as UART, USB, Ethernet, SPI, or I2C.
• Experience analyzing network communication and diagnosing storage or I/O issues on embedded platforms.
• Ability to write diagnostic tools or scripts (e.g., Bash, Python) with a strong analytical troubleshooting mindset.

Nice to have:

• Experience with robotics or UAV platforms.
• Familiarity with PX4, ArduPilot, or other flight controllers.
• Experience with custom board bring-up and embedded Linux build systems.
• Familiarity with debugging tools such as logic analyzers or oscilloscopes.

Flight controller and communication integration:

• Integrate and troubleshoot flight controllers and communication interfaces such as UART, USB, and Ethernet, including third-party component integration.

System behavior analysis:

• Analyze behavior across operating systems, drivers, firmware, and hardware interfaces.
• Work closely with software and hardware teams to implement design changes during product development, especially addressing failures in field conditions.

Network, storage, and I/O diagnostics:

• Investigate network, storage, and I/O issues across embedded devices.
• Develop diagnostic scripts, tools, and debugging procedures with other engineers.

Interoperability diagnosis:

• Diagnose communication and interoperability issues across embedded systems in collaboration with cross-functional teams.
• Define appropriate components, cables, and interface specifications for reliable multi-device deployments.

Fault identification and security support:

• Identify faults related to grounding, interference, signal integrity, cabling, and electrical integration.
• Coordinate root-cause analysis and corrective actions with hardware and software engineers.
• Support hardware-related security measures on integrated boards.
• Address cases where one device damages others connected to it.
