Staff Hardware Engineer, Optics

About Marvell

Marvell’s semiconductor solutions are the essential building blocks of the data infrastructure that connects our world. Across enterprise, cloud and AI, and carrier architectures, our innovative technology is enabling new possibilities.

At Marvell, you can affect the arc of individual lives, lift the trajectory of entire industries, and fuel the transformative potential of tomorrow. For those looking to make their mark on purposeful and enduring innovation, above and beyond fleeting trends, Marvell is a place to thrive, learn, and lead.

Your Team, Your Impact

The Cloud Platform Optics team builds high-speed optical platforms that combine silicon photonics, transmit and receive amplifiers, controller ASICs, Marvell DSPs, and embedded firmware. This work sits within Marvell’s broader AI interconnect portfolio, which spans scale-out networking across racks and clusters, scale-up connectivity between accelerators, and scale-in connectivity between dies and chiplets inside a package.

You’ll own the electrical design of an optical module or a defined subsystem and spend hands-on time in the lab bringing it to life. You’ll work directly with the engineers who design the DSP, photonics, and firmware, see how your board decisions affect link performance and power, and carry your design from the first prototype through new product introduction (NPI).

What You Can Expect

- Design the hardware you’ll bring up. Translate platform requirements into schematics, component selections, and PCB layout constraints for power delivery, clocking, control interfaces, and high-speed signal paths.
- Take first silicon and boards from power-on to a working link. Set up the bench, verify rail voltages and sequencing, check clocks and resets, establish register access, and debug the electrical and optical interfaces alongside firmware and photonics engineers.
- Measure performance against a defined specification. Set pass/fail limits for metrics such as rail ripple, module power, bit error rate (BER), and link margin. Run tests across relevant voltage, temperature, and operating conditions, then document margin to spec and where it breaks down.
- Close the loop on hardware failures. Reproduce intermittent issues, isolate the cause across hardware, firmware, and optics, and verify the fix with before-and-after measurements on updated hardware or firmware.
- Move the design into manufacturing. Support pilot builds, correlate bench and production-test results, and hand off validated test procedures, debug instructions, and design documentation to NPI and manufacturing teams.

What We're Looking For

- Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field with 3–5 years of relevant hardware engineering experience, or a master’s degree or PhD in a related field with 2–3 years of relevant experience. Equivalent professional experience in lieu of a degree is welcome.
- Hands-on ownership of at least one PCB or electrical subsystem through schematic capture or layout review, first power-on, and bench validation. Experience with Cadence OrCAD, Allegro, or comparable ECAD tools.
- Experience personally measuring at least two board-level parameters , such as rail ripple, power-sequencing timing, clock frequency or jitter, or current draw. Comfortable setting up and using oscilloscopes, programmable power supplies, multimeters, and logic analyzers as appropriate.
- Experience debugging at least one board-level control interface , such as I²C, SPI, or UART, using bus captures, register reads, or firmware logs to isolate a fault.
- At least one example of taking a hardware issue from symptom to verified fix. Be prepared to explain your bench setup, the original measurement, the change you made, and the measured result against a target. Examples include reducing ripple below its specified limit, restoring link margin, resolving a sequencing violation, or improving repeatability across test runs.

Preferred Qualifications

- Hands-on bring-up or validation of optical transceivers or high-speed hardware with serial lanes operating at 25 Gb/s or faster . Experience with eye measurements, BER testing, or 100G- or 200G-per-lane PAM4 is a plus.
- Python or similar scripting experience for instrument control, register access, or automated test and data collection. Familiarity with CMIS or optical module management is valuable.

Experience applying signal and power integrity principles to PCB design, debugging thermal or EMI/EMC issues, or supporting optical Ethernet and data center interconnect platforms
