Company

hirify.global is a security technology company developing autonomous machines, AI-driven software, and managed security services.

What you will do

• Lead software system design and subsystem development for a wearable technology product from early prototyping through production readiness.
• Interface with IMU gyroscope and accelerometer sensors through SPI or I2C, process raw data in real time, and perform calibration for bias, drift, noise, and temperature compensation.
• Implement sensor fusion algorithms, including Kalman or Madgwick filters, to estimate orientation and motion.
• Develop electronic image stabilization algorithms, calculate camera motion trajectories, and apply correction transforms to video frames.
• Integrate and optimize the stabilization pipeline for real-time execution on NVIDIA Jetson, ARM SoC, or other embedded target hardware.
• Design validation procedures, benchmark latency, jitter, and stabilization accuracy, and debug sensor, frame-drop, and timing issues in collaboration with mechanical, electrical, systems, camera, and software engineers.

Requirements

• B.S. or M.S. degree in Computer Science, Electrical Engineering, or a related field.
• 7+ years of software engineering experience, including shipping software on hardware products.
• Hands-on experience interfacing with IMU or other MEMS sensors.
• Experience with real-time systems and low-latency data processing.
• Strong proficiency in C and C++.
• Experience with SPI, I2C, and UART communication protocols.
• Solid understanding of digital signal processing concepts and familiarity with sensor fusion techniques such as Kalman and complementary filters.
• Experience with Linux-based embedded systems or RTOS, including FreeRTOS or Zephyr.
• Prior work on image or video processing pipelines is strongly preferred.

Nice to have

• Experience with robotics, drones, action cameras, or autonomous vehicles.
