Embedded Software Engineer

Job Description

Job Description

Position Overview :

Extropic is seeking a highly skilled Embedded Software Engineer with deep experience in both bare-metal firmware development and embedded Linux application design. The ideal candidate should have a strong background working with heterogeneous multi-core RISC-V or ARM processors (e.g., Cortex-R5, Cortex-A53), excel in C / C++ and Python programming languages, and be comfortable developing across the entire embedded software stack—from low-level drivers to Linux user-space applications to host-side tooling.

This role is highly hands-on and involves close interaction with the systems, IC design, test, and physics cross-functional engineering teams. You will architect, implement, and debug complex embedded systems, integrating multiple processors, real-time firmware, and Linux-based applications.

Key Responsibilities

• Architect, design, and implement embedded software across bare-metal, RTOS, and embedded Linux environments.
• Develop firmware, Linux drivers, user-space applications, and host-PC tools supporting the full embedded software stack.
• Work with heterogeneous multi-core SoCs (e.g., Cortex-R5 real-time cores and Cortex-A53 application cores), enabling inter-processor communication, synchronization, and resource sharing.
• Implement multi-threaded, multi-core software architectures with attention to power, performance, determinism, and reliability.
• Develop and maintain low-level drivers for peripherals including SPI, I2C, UART, GPIO, timers, and DMA engines.
• Debug real-time embedded systems using JTAG / SWD debuggers, in-circuit emulators, and software diagnostic tools.
• Perform hands-on system characterization using oscilloscopes, logic analyzers, and protocol analyzers (SPI / I2C / UART, LVDS, Ethernet, USB, etc.).
• Write clean, robust, well-tested C / C++ code for bare-metal and Linux environments.
• Develop Python tools for automation, test, and host-side applications.
• Collaborate closely with hardware, FPGA, and systems engineers to bring up new boards, validate interfaces, and resolve integration issues.
• Contribute to system architecture decisions, design reviews, and technical documentation.
