Duration: 12+ Month Contract With Potential for a Fulltime Position

Saige Partners is seeking an experienced Senior Embedded Systems Engineer to support hardware and software integration efforts for next‑generation IoT devices running on Arm-based processors.

The Senior Embedded Systems Engineer is responsible for developing, testing, and maintaining embedded software and hardware solutions to support the manufacturing of our products and to analyze and evolve product designs to maintain production viability. The ideal candidate has strong experience with microcontrollers, real‑time operating systems, low‑level software, and hardware‑software integration & debugging. This role collaborates closely with hardware engineers and product operations to deliver reliable integrated solutions.

• Design, develop, and maintain embedded software for microcontroller and processor-based systems as part of supporting manufacturing, field issue, and production ramp‑up activities.
• Develop and debug firmware drivers for peripherals such as UART, SPI, I2C, CAN, GPIO, ADC, and timers as part of root cause of failure evaluations and end‑of‑life component replacements.
• Integrate embedded software with custom hardware designs.
• Work with RTOS environments & round‑robin scheduler.
• Perform system bring‑up, debugging, and root‑cause analysis using tools such as oscilloscopes, logic analyzers, and debuggers.
• Select and qualify electronic components based on performance, cost, availability, and lifecycle as part of supporting end‑of‑life component replacement.
• Collaborate with electrical, mechanical, and firmware engineers to define test system architecture and interfaces as part of supporting manufacturing, field issue, and production ramp‑up activities.
• Create and maintain technical documentation, including design specifications, schematics, BOMs, test reports & work instructions as part of supporting manufacturing, field issue, and production ramp‑up activities.
• All other duties as assigned.

• Bachelor's degree in Electrical or Computer Engineering, Computer Science, or a related field.
• 3+ years of experience developing embedded systems with hardware integration.
• Proficiency in C/C++ for embedded environments.
• Experience with ARM Cortex‑M or similar microcontroller architecture.
• Solid understanding of embedded fundamentals: memory management, interrupts, timing, concurrency & threading.
• Knowledge of communication protocols such as USB, BLE, RS232.
• Experience debugging at the hardware/software boundary.
• Experience working with hardware design concepts (schematics, datasheets, board bring‑up).
• Familiarity with version control systems (e.g. Git).

• Experience with scheduling concepts & memory management.
• Experience with bootloaders, firmware updates.
• Knowledge of reliability‑critical systems (automotive, medical).
• Familiarity with scripting languages (Python, Bash) for test automation.
