High-Speed SerDes & Mixed-Signal Validation Engineer

Your Team, Your Impact The Hardware and Silicon Validation team in Marvell's Connectivity Business Group designs and builds the electrical and optical test platforms, benches and measurement methods used to bring up, characterize and validate Marvell's next-generation high-speed and optical interconnect products. The team is staffing a new VCSEL-based optical interconnect program that spans electro-optical chiplets and products, multiple optics vendors, and the evaluation boards, instrumentation and automated benches . You will work with multi-disciplinary teams (analog, DSP, digital, firmware and software, packaging, optics and PCB design) in fully equipped labs. You will be involved in complex lab testing, hardware bring-up and all facets of the prototype process, including PCB fabrication and assembly. Marvell provides high-speed analog and mixed-signal semiconductor solutions and optical interconnects for communication infrastructure and cloud data centers. What You Can Expect

• Independently own a test platform, bench or board design from requirements to bring-up. Plan and lead work on new projects, resolve conflicts, and technically own the work of more junior engineers.
• Design and develop electrical and optical test platforms and benches for VCSEL-based optical interconnect: define the bench architecture, select and qualify instruments, and build in calibration, automation and correlation across labs.
• Design and develop the hardware these benches and platforms need, including PCBs, evaluation and characterization boards, test fixtures, and optical and electrical adapters: requirements, schematic, stack-up, SI/PI, layout, fabrication and assembly follow-up, and bring-up, working with outsourced partners where needed.
• Develop new measurement techniques and methodologies for optical links (optical power, spectrum, eye and waveform, BER, noise and jitter, link margin) and for high-speed electrical interfaces. Evaluate new instruments and tools, and define the requirements for their purchase.
• Bring up, debug and characterize electro-optical chiplets and products with the silicon, analog, DSP and firmware teams. Define and execute validation and characterization plans from first silicon through product tape-out.
• Work with multiple optics vendors: define test requirements, qualify VCSEL, photodetector and module samples, and correlate results across vendors and sites.
• Automate benches and data flows in Python (instrument control, data collection, statistical analysis and correlation).
• Write test plans, characterization reports, bench and board design guidelines, and application collateral.
• Engage independently with cross-functional teams and vendors, and represent the work to internal stakeholders.
