Sr. Software Engineer, Firmware-; TF

Ampere is a semiconductor design company for a new era, leading the future of computing with an innovative approach to CPU design focused on high-performance, energy efficient AI compute.

As a pioneer in the new frontier of energy efficient high-performance computing, Ampere is part of the Softbank Group of companies driving sustainable computing for AI, Cloud, and edge applications.

About the Role:

Ampere is seeking a Senior Software Engineer to design, develop, and support low-level platform firmware for Armv9-based systems. In this role, you will focus on Trusted Firmware-A (TF-A) and related platform software, working at the intersection of hardware and software to enable secure, reliable, high-performance compute platforms.

You will collaborate closely with hardware design, validation, and software engineering teams throughout the product lifecycle—from pre-silicon development on models, emulation, and FPGA platforms through post-silicon bring-up, validation, release, and customer support. This is an opportunity to solve complex system-level problems, influence firmware architecture, and contribute to technology used by internal teams, customers, and the broader open-source community.

What You’ll Achieve:

• Design, develop, integrate, and maintain Trusted Firmware-A (TF-A) for Armv9-based platforms.
• Define and maintain firmware specifications, architecture and design documentation, and technical collateral.
• Enable and validate pre-silicon software support across hardware models, emulation environments, and FPGA platforms.
• Lead post-silicon platform bring-up; diagnose complex issues and drive them through root cause, resolution, and validation.
• Debug challenging problems spanning firmware, boot flows, operating systems, and platform subsystems.
• Deliver features end-to-end, from requirements and implementation through validation, release, and lifecycle support.
• Partner with hardware design, validation, and software teams to ensure robust platform integration and product readiness.
• Support multiple platforms and projects for internal stakeholders and external customers.
• Work directly with customers to diagnose, communicate, and resolve technical issues in a timely manner.
• Produce technical whitepapers and other materials that support product marketing, customer engagement, and open-source outreach.
• Write high-quality, maintainable production code; participate in code reviews and help continuously improve engineering practices and development processes.

About You:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, Information Technology, or a related technical field—or equivalent practical experience.
• 5+ years of relevant experience with a bachelor’s degree, or 3+ years of relevant experience with a master’s degree.
• Strong C/C++ and Arm assembly-language programming skills.
• Hands‑on experience with 32-bit and 64-bit Arm architectures, including Armv8;
  Armv9 experience is strongly preferred.
• Experience developing low-level software, including firmware, TF-A/ATF, BIOS/UEFI, bootloaders, Linux, or Windows platform software.
• Strong analytical, debugging, validation, and test‑methodology skills.
• Knowledge of microcontroller hardware interfaces and protocols, including SPI, I2C, DDR3/DDR4/DDR5, and PCIe.
• Experience using source control, CI, and issue‑tracking tools such as Git, Jenkins, Bugzilla, and Jira.
• Experience with hardware/software debug tools such as JTAG, Lauterbach TRACE
  32, GDB, and/or OpenOCD.
• Strong understanding of software development lifecycle processes and Agile development methodologies.
• Demonstrated ability to independently own complex technical problems, work across multiple subsystems, and drive issues to resolution.
• Experien…
