Job Description

F5 is seeking an accomplished Principal Firmware/Diagnostics Engineer to lead the development of reliable, secure, and serviceable firmware and diagnostics across the full product lifecycle, from hardware bring-up and boot loaders through runtime services and field upgrades. As a key member of the Hardware Development Team, you will provide technical leadership and mentoring, drive roadmap execution and elevate engineering excellence, and partner cross‑functionally to deliver platform capabilities that delight customers and meet stringent security and compliance expectations (e.g., secure boot, code signing, measured boot). This role requires deep expertise in firmware/software design and the ability to influence architecture decisions, ensure design excellence, and foster innovation.

Key Responsibilities

• Uphold F5's Business Code of Ethics and promptly report violations of the Code or other company policies.
• Act as a technical authority, establishing standards for secure boot, code-signing, anti-rollback protections, measured boot, vulnerability remediation, and incident response.
• Lead firmware and diagnostics design for new products, including architecture definition, functional specifications, and requirements development. Work with cross‑functional teams to align requirements and shepherd PRDs into executable plans.
• Assist in the planning of work across boot, board bring-up, drivers, runtime services, manufacturing/test firmware, and in-field update mechanisms.
• Define telemetry, detection, and recovery strategies for firmware integrity, and align to relevant standards (e.g., FIPS 140-3, FedRAMP implications as applicable).
• Define automated build, test, and validation, ensuring repeatable releases and traceable artifacts across SKUs.
• Drive design for manufacturability, testability, and reliability across all phases of development. Partner with MFG and Global Services to define factory programming, golden images, and resilient upgrade strategies (A/B, recovery partitions).
• Research and evaluate emerging technologies to enhance existing products and guide new product directions.
• Oversee and mentor engineers, providing technical guidance and reviewing work to ensure quality and efficiency. Serve and guide other team members through challenges, assuring their growth and project success
• Conduct internal and external technical presentations and disseminate knowledge within the Hardware Development Team.
• Develop and maintain schedules for deliverables, ensuring timely and high-quality documentation and testing through holistic ownership over assigned product areas and projects. Provide status, risks, and decisions to leadership; translate technical details into business outcomes.
• Interface with suppliers and manufacturing partners for validation and issue resolution.
• Support sustaining engineering for legacy products and assist in manufacturing training for new designs.
• Participate in design reviews and contribute to continuous improvement of design processes and standards.
