Sr. Embedded Software Engineer

** US Citizenship or Green Card Holder is required for this position. We are unable to hire individuals who need a work visa, are currently on a work visa, or individuals who will require work visa sponsorship in the future. **

At Teledyne FLIR in Orem, we design and develop unmanned aircraft systems and mission‑critical payloads that operate in demanding environments. Our teams work closely with defense and security partners to deliver reliable, fielded systems where robustness, performance, and maintainability matter. We are a small, collaborative engineering team focused on solving real problems with disciplined engineering and clear ownership.

We are seeking a Sr. Embedded Software Engineer to develop and integrate software for small unmanned aircraft systems and associated subsystems. This is a hands‑on, product‑focused role spanning microcontrollers, RTOS‑based systems, and embedded Linux. The ideal candidate is a strong individual contributor who can work independently, contribute effectively from day one, and reason about software behavior across hardware and software boundaries.

This role values system‑level awareness and the ability to participate meaningfully in architectural decisions while continuing to produce high‑quality embedded code.

• Develop embedded software in C and C++ for microcontrollers, RTOS‑based systems (e.g., Zephyr or similar), and embedded Linux platforms
• Design and implement core embedded constructs such as state machines, timing‑sensitive logic, and basic algorithms
• Integrate software across multiple interconnected processors and subsystems, including sensors, cameras, and payload devices
• Develop and maintain low‑level drivers and hardware interfaces
• Work with common embedded communication protocols such as I2C, SPI, UART, and Ethernet
• Perform system‑level debugging using tools such as logic analyzers, oscilloscopes, and in‑circuit debuggers
• Own features from initial design through implementation, integration, testing, and field support
• Contribute to system architecture and interface design in collaboration with other engineers
• Build and maintain internal tools, test utilities, and automation, often using Python

• 5+ years of professional experience developing embedded software for production systems
• Strong proficiency in C and C++ for embedded targets
• Experience working across multiple layers of an embedded system, including MCU firmware, RTOS‑based software, and embedded Linux
• Solid understanding of microcontroller peripherals and inter‑device communication protocols
• Demonstrated ability to debug complex hardware/software interactions and resolve system‑level issues
• Experience delivering reliable embedded software in a collaborative engineering environment

• Experience with UAS software stacks or autopilot systems, particularly PX4, including integration with sensors, payloads, or higher‑level system components
• Experience developing firmware for microcontrollers, including peripheral configuration and low‑level driver development
• Experience with real‑time operating systems such as Zephyr, FreeRTOS, or similar
• Board bring‑up and low‑level hardware/software debugging experience
• Familiarity with STM
  32, NVIDIA Jetson, or similar embedded platforms
• Exposure to UAS, robotics, or other complex embedded systems

Applicants must be either a U.S. citizen, U.S. national, legal permanent resident, asylee, refugee or must be eligible to apply for and obtain the appropriate export control license from the U.S. Departments of State or Commerce.
