Principal System Diagnostics Engineer
About The Position
Marvell is hiring a Principal System Diagnostics Engineer to develop and deliver diagnostics for network switch hardware. The role focuses on low-level diagnostic software, test suites, and APIs used to exercise and validate hardware components, including ASICs, high-speed SerDes, memory interfaces, PCIe, power management, and thermal control systems. The engineer will support initial board bring-up and prototype debugging, develop diagnostic coverage for factory manufacturing, and build automated frameworks to run tests, collect metrics, and analyze failures. The position works closely with hardware, ASIC design, embedded firmware, and Network OS teams to define diagnostic requirements and hardware-testability hooks. It also provides technical guidance and mentoring to junior engineers and helps identify and mitigate platform testability and production-readiness risks. Marvell develops semiconductor solutions for enterprise, cloud and AI, and carrier data infrastructure. The role is eligible for bonus and equity plans, including a new-hire equity grant and annual equity refreshers. Marvell also offers employee stock purchase, family support programs, mental health resources, and recognition and service awards. The expected base pay range is $150,680–$225,700 per annum; starting pay depends on job-related skills, experience, qualifications, work location, and market conditions.

Responsibilities
- Design and implement low-level diagnostic software, test suites, and APIs to exercise and validate network switch hardware components.
- Develop test plans for ASICs, high-speed SerDes, memory interfaces such as DDR/HBM, PCIe buses, power management, and thermal control systems.
- Partner with hardware design and silicon teams during initial board bring-up, debug prototype hardware, and isolate root-cause issues.
- Deliver diagnostic test coverage for integration into factory manufacturing lines.
- Build automated testing frameworks and scripts to execute diagnostic software, collect metrics, and analyze failure data.
- Work with Hardware Engineering, ASIC Design, Embedded Firmware, and Network OS teams to define diagnostic requirements and hardware-testability hooks.
- Mentor junior engineers in diagnostic software development and hardware debugging, and provide technical guidance.
- Identify hardware-testability and production-readiness risks across the platform stack, develop mitigation strategies, and escalate issues to drive resolution.
- Manage test relationships with ODM/JDM or CM partners.
Benefits
- Eligible to participate in bonus and equity plans, including a new-hire equity grant and annual equity refreshers.
- Employee stock purchase plan with a 2-year look back.
- Family support programs to help balance work and home life.
- Mental health resources.
