Principal Firmware Engineer

Principal Firmware Engineer

The Microsoft Azure team is seeking a highly experienced Principal Firmware Engineer to lead the development of firmware, debugging, and validation of next-generation firmware solutions for Microsoft AI accelerators and cloud silicon platforms.

This role is focused on the design, development, debug, and deployment of silicon firmware libraries focused on Compute Domains and ANC (Accelerator Network Controller). This will require deep expertise in SoC architecture, low-level firmware, silicon bring-up, hardware/software co-design, and platform initialization flows. The candidate will serve as a technical leader driving IP Firmware library architecture across multiple silicon programs while collaborating with hardware architects, validation engineers, security and Platform firmware and software teams. The role needs to be technical hands on leaders who will influence architecture across teams, mentor others, drive complex initiatives, and effectively communicate with executives, customers, and engineering stakeholders.

Responsibilities

• Define and drive firmware architecture for Silicon firmware libraries for HBM, ANC, Compute, and SoC infrastructure subsystems.
• Influence microarchitecture decisions by working closely with silicon architects during specification and design phases.
• Lead firmware strategy across multiple silicon generations and platform programs.
• Provide technical leadership across firmware, hardware, validation, and software organizations
• Develop silicon firmware libraries in C/C++ for Compute engines, ANC sub system, DMA Engines, and other similar IP blocks
• Develop scalable and maintainable firmware frameworks and APIs.
• Lead first-silicon bring-up activities.
• Drive root-cause analysis for firmware, hardware, performance, and validation issues.
• Define firmware verification requirements and test plans.
• Lead cross-team initiatives spanning firmware, silicon architecture, software, security, and system integration.
• Create engineering alignment across geographically distributed teams.
• Collaborate with Azure hardware, platform software, systems, and validation organizations.
• Represent firmware technical direction in leadership and architecture reviews.
• Mentor engineers.
• Develop engineering best practices, coding standards, and architectural review processes.

Minimum Qualifications

• Doctorate in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 3+ years technical engineering experience OR Master's Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 6+ years technical engineering experience OR Bachelor's Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 8+ years technical engineering experience OR equivalent experience.

Other Requirements:

Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include, but are not limited to, the following specialized security screenings:

• Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.
