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

Cloud Optics Applications Engineering – responsible for customer-facing technical engagement, optical module qualification, system validation, and debug across hyperscale and data center deployments.

What You Can Expect

  • Lead end‑to‑end debug and root‑cause analysis across optical, electrical, firmware, and system layers, including interoperability between modules, switches/routers, and optical line systems
  • Partner closely with a hyperscale customer on product bring‑up, qualification execution, technical escalations, test plans and product definitions
  • Define, develop, and execute validation and debug test plans for coherent pluggable optics (e.g., 400G/800G/1.6T ZR/ZR+) operating within open line systems and network equipment
  • Develop Python-based automation for test execution, data collection, and analysis
  • Drive clear technical communication and corrective actions with internal engineering teams
  • Create essential technical documentation (application notes, qualification summaries, debug reports)

What We're Looking For

  • Bachelor’s degree in EE, Optical Engineering, or related field (Master’s preferred)
  • 8–12+ years experience in Applications engineering, system/network validation, or optical module engineering
  • Strong hands-on lab experience with optics and system-level testing
  • Proficiency in Python for automation and data analysis
  • Proven ability to lead complex technical investigations independently
  • Experience working directly with hyperscale or large cloud customers
  • Hands-on experience with coherent optical modules (e.g., 400G/800G ZR/ZR+) in end-to-end network environments, including validation across switches and routers running SONiC, IOS‑XR, EOS, Junos, and similar network OSes on whitebox and OEM platforms (Cisco, Arista, Juniper, Nokia).
  • Strong background in Physical layer (Layer 1/Layer 2) interoperability testing, system bring-up, and cross-domain debug spanning optical performance, host interfaces, and network behavior.

Expected Base Pay Range (USD)

173,800 - 257,190, $ 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.

Our offerings are built around four key pillars: financial well-being, family support, mental and physical health, and recognition.

These tools must not be used to record, assist with, or enhance responses in any way. Our interviews are designed to evaluate your individual experience, thought process, and communication skills in real time. Use of AI tools without prior instruction from the interviewer will result in disqualification from the hiring process.
