Job summary

Fortaegis is seeking an experienced Embedded Linux / Firmware Engineer to develop robust, secure low-level software for ARM Cortex-A SoCs, from boot to kernel. You will work across pre-silicon validation to post-silicon bring-up, ensuring top quality and security while collaborating with hardware and architecture teams.

The role emphasizes kernel-level driver work, device trees, unit testing, and secure firmware features across the stack, with a focus on performance and robust APIs.

Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• 5+ years of experience in firmware and embedded software development, with a strong focus on embedded systems.
• Proven expertise with ARM Cortex-A processors and their peripherals.
• Hands-on Linux kernel development experience: writing and debugging device drivers, working with device tree, and diagnosing issues in kernel space.
• Demonstrable experience with firmware unit testing and involvement in pre-silicon and post silicon development phases.
• Solid understanding of good API and design skills for robust and maintainable code.
• Experience with the TCP/IP stack in a kernel or embedded context, covering sockets, network drivers, and performance tuning.
• Excellent collaboration and communication skills, with a track record of working effectively with hardware, architecture, and cross-functional teams.

Responsibilities

• Design, develop, and debug firmware and low-level system software for ARM Cortex-A based SoCs and their peripherals.
• Develop and maintain Linux kernel code: device drivers, device tree, and platform and bus level integration for new silicon.
• Implement and execute comprehensive unit testing strategies to ensure code quality and reliability.
• Actively participate in both pre-silicon and post-silicon validation and bring-up activities, including work on emulation and FPGA prototyping platforms.
• Collaborate closely with hardware and architecture teams to define specifications, troubleshoot issues, and optimize performance.
• Contribute to the design and implementation of secure firmware features across the software stack.
• Develop high-quality, well-documented APIs and maintain strong design principles throughout the development process.
• Work effectively within a collaborative team environment, sharing knowledge and best practices.
• Develop and integrate the TCP/IP networking stack on the kernel side, including network device drivers and packet datapath work.
