We are seeking a talented and driven Staff Firmware Engineer to join our team and contribute to the core device-side software stack of machine learning for the Next Gen Computational Flash Controller project. In this role, you will be a key contributor to the firmware that enables high-performance communication and data transfer between the host and our device. You'll work on critical components, including the PCIe driver, DMA engine, MMIO, and Mailbox interfaces, to ensure a seamless and efficient ML workload.

Key Responsibilities 🛠️

• PCIe Driver Development: Design and implement firmware for the device's PCIe driver, ensuring robust and high-speed communication with the host. You will be responsible for handling interrupts, managing queues, and optimizing data flow.
• Data Path Engineering: Develop and optimize firmware for the DMA engine, orchestrating high-bandwidth data transfers between the host and on-device memory.
• Hardware Interface: Implement and manage firmware for MMIO (Memory-Mapped I/O) and Mailbox communication, enabling the host software to configure the device and send commands.
• Protocol Implementation: Work on firmware that implements a subset of the NVMe protocol or similar high-performance interfaces to streamline data and command transfers.
• Debugging and Optimization: Utilize your expertise to debug complex, system-level issues related to PCIe, DMA, and MMIO. You will profile the firmware and optimize its performance to maximize the throughput of ML workloads.

Collaboration: Work closely with the host-side software teams, hardware engineers, and other firmware engineers to ensure a cohesive and high-performing end-to-end solution

• Experience: 5+ years of hands-on experience in firmware or embedded systems development.
• Technical Expertise:
  • Strong proficiency in C/C++ for low-level programming.
  • Hands-on experience with PCIe and developing firmware or drivers for high-speed interfaces.
  • Solid understanding of system architecture, including DMA engines and MMIO.
  • Experience with implementing communication protocols via a Mailbox or similar shared memory mechanisms.
  • Familiarity with the NVMe specification is a plus.
• Debugging Skills: Proven ability to debug complex hardware-firmware interactions using tools like JTAG/SWD, logic analyzers, and protocol analyzers.
• Problem-Solving: Strong analytical skills and a passion for solving challenging, low-level problems.
• Education: Bachelor's or Master's degree in Computer Science, Electrical Engineering, or a related field.
