Embedded Software Engineer III

The Embedded Software Engineer III contributes to the development and optimization of firmware and embedded software for Kopin’s next-generation AR/VR HUDs and micro-display products. This role requires strong proficiency in embedded systems, real-time algorithm implementation, and hands-on experience with hardware/software integration. The role develops software for custom hardware platforms including ARM processors, microcontrollers, and FPGA-adjacent logic and ensures robust, reliable operation across imaging, tracking, display-pipeline, and sensor-driven subsystems. This role works collaboratively across electrical, systems, optics, and mechanical engineering teams and participates throughout the full software development life cycle from design and implementation through testing, integration, and documentation., * Design, implement, and maintain firmware and low-level embedded software for portable and wearable devices.

• Develop device drivers, hardware abstraction layers, and board support package components for custom ARM- and MCU-based platforms.
• Optimize image-processing and digital signal-processing algorithms for real-time execution on resource-constrained embedded hardware.
• Implement and manage multithreading, interrupt handling, and task scheduling inside RTOS or bare-metal environments.
• Utilize co-processing units (DSP blocks, GPU pipelines, SIMD, or FPGA-accelerated paths) to increase computational throughput.
• Work closely with hardware engineers to define firmware-to-hardware interface requirements, timing expectations, and configuration sequences.
• Troubleshoot and debug system-level issues involving display timing, sensor data alignment, memory bandwidth, and peripheral communication.
• Apply knowledge of discrete filters, Fourier transforms, linear systems, and fixed-point arithmetic to practical signal-processing tasks.
• Participate in full software lifecycle activities including design documentation, code reviews, unit tests, regression tests, and integration testing.
• Contribute to imaging, display, or sensor-based demo applications used for internal evaluation and customer demonstrations.
• Collaborate with Systems Engineering to ensure embedded implementations satisfy system requirements, timing budgets, and performance margins.
• Maintain firmware architecture and ensure modularity, clarity, and long-term maintainability across code bases.
