Your Team, Your Impact

Marvell is at the center of the data infrastructure revolution-powering the backbone of cloud, AI, and high-performance computing. Our Optical DSP (ODSP) Applications Engineering team sits at the intersection of silicon, systems, and customers-turning breakthrough technology into real-world deployments at massive scale.
You'll join a team that directly enables next-generation hyperscale data centers, working alongside world-class silicon designers, system architects, and leading cloud customers. This is where cutting-edge PAM4 DSP, advanced process nodes, and high-speed optical interconnects converge to solve some of the hardest problems in scaling AI infrastructure.

What You Can Expect

This is not a support role-it's a front-line engineering leadership position with direct influence on customer success and revenue.

As a Principal Applications Engineer, you will:

• Serve as the primary technical interface for key customers integrating Marvell's Optical DSP solutions into next-generation AI and datacenter platforms
• Drive end-to-end system success, from early design-in through bring-up, validation, and production deployment
• Lead complex issue resolution with urgency and precision-problems you solve will have immediate business and customer impact
• Shape the future of our products by translating real-world customer challenges into actionable feedback for design and product teams
• Operate at the forefront of scale-out architectures, enabling the high-bandwidth, low-latency connectivity required for modern AI workloads
• Work hands-on in the lab with high-speed systems, pushing the limits of performance across optical, electrical, and system domains

What We're Looking For

Required:

• Deep understanding of DSP fundamentals, analog/mixed-signal circuits, and high-speed SerDes systems
• Strong system-level hardware knowledge, with the ability to debug across multiple domains
• Hands-on lab experience with TX/RX validation, high-speed measurement equipment (oscilloscopes, BERTs, VNAs, etc.)
• Proven track record of owning and resolving complex technical issues end-to-end
• Experience in applications engineering or customer-facing roles supporting advanced semiconductor or system products
• Familiarity with optical transceiver architectures and PAM4-based DSP systems
• Strong communication skills and ability to influence both customers and internal stakeholders
• Knowledge in C and/or Python is a plus
• BS in Electrical Engineering with 8-12 years of experience, or MS/PhD with 5+ years

Expected Base Pay Range (USD)

154,680 - 231,700, $ per annum

The successful candidate's starting base pay will be determined based on job-related skills, experience, qualifications, work location and market conditions. The expected base pay range for this role may be modified based on market conditions.
