How much do serdes test engineer jobs pay per hour?

As of Sep 12, 2026, the average hourly pay for serdes test engineer in the United States is $59.03, according to ZipRecruiter salary data. Most workers in this role earn between $44.71 and $75.96 per hour, depending on experience, location, and employer.

What is a Serdes Test Engineer?

A Serdes Test Engineer is a professional who specializes in testing serializer/deserializer (SerDes) components used in high-speed data communication interfaces. Their responsibilities typically include developing and executing test plans, validating signal integrity, debugging hardware and firmware issues, and ensuring compliance with industry standards. They work closely with design and validation teams to identify and resolve performance or reliability issues in SerDes circuits. This role requires strong knowledge of high-speed digital electronics, test equipment, and protocols such as PCIe, Ethernet, or USB.

What are the key skills and qualifications needed to thrive as a Serdes Test Engineer?

To thrive as a Serdes Test Engineer, you need a solid background in electrical engineering, signal integrity, and high-speed digital design, often supported by a relevant degree. Proficiency with oscilloscopes, bit error rate testers (BERTs), lab automation software, and familiarity with industry standards like PCIe or Ethernet is typically required. Strong problem-solving, attention to detail, and effective communication skills help you diagnose issues and collaborate with cross-functional teams. These competencies ensure accurate validation of Serdes interfaces, which is vital for reliable high-speed data transmission in modern electronic systems.

What are some typical challenges faced by Serdes Test Engineers during validation and how are they addressed?

Serdes Test Engineers often encounter challenges such as signal integrity issues, jitter, and crosstalk when validating high-speed serial interfaces. Addressing these requires a deep understanding of test equipment, careful setup of test environments, and collaboration with design and layout teams to troubleshoot root causes. Engineers frequently use oscilloscopes, BERTs, and protocol analyzers to capture and analyze signal anomalies, and may need to adjust test methodologies or recommend design changes to meet compliance standards.

Job description

At Nexthop AI, we are a team of industry-leading experts with deep experience across silicon design, systems engineering, network operations, and cloud infrastructure. We are building innovative, next-generation solutions to meet the demands of large-scale AI deployments that will power tomorrow's AI infrastructure. We are now expanding our optical engineering team and looking for an Optical Test Engineer.
As an Optical Test Engineer, you'll be responsible for the qualification, validation, and system-level testing of high-speed optical modules (e.g., 400G, 800G, 1.6T) used in advanced datacenter and AI networking environments. You'll help bring up test platforms in the lab, perform optical and electrical measurements, and analyze performance under different test conditions, configurations and workloads. Your work will directly support the scalability, efficiency, and reliability of next-generation AI systems.
Key Responsibilities:
  • Lab Bring-Up and Test Automation: Setup and maintain test environments using BERTs, power meters, oscilloscopes, and traffic generators. Automate workflows using Python.
  • Optical Module Qualification: Test and characterize transceivers across temperature, voltage, and traffic conditions to ensure performance and compliance.
  • System-Level Validation: Validate module performance in switch ASIC systems and AI networking setups. Capture metrics like BER, power consumption, thermal stability, and link reliability under stress.
  • Debug and Analysis: Troubleshoot performance issues such as signal integrity degradation, module misbehavior, or unexpected power/thermal behavior. Collaborate with cross-functional teams for root-cause analysis.

Required Qualifications:
  • B.S. or M.S. in Electrical Engineering, Optical Engineering, Physics, or a related field
  • 5+ years of experience testing optical modules or electrical/optical systems
  • Hands-on experience in high-speed optical transmission testing, including fiber links, and state of the art test equipment: BERT, oscilloscope, DCA, power meters, OSA, thermal chambers
  • Strong Python scripting skills for lab automation and programming languages for data collection and analysis
  • Familiarity with CMIS, MDIO, or I²C interfaces
  • Understanding of high-speed protocols such as Ethernet, PCIe, or SerDes
  • Ability to work in a fast-paced startup environment and adapt to evolving priorities.

Preferred Qualifications:
  • Industry experience working with 400G/800G/1.6T pluggable modules (QSFP-DD, OSFP)
  • Knowledge of IEEE 802.3 Ethernet, MSA or OIF standards including CMIS
  • Experience validating hardware in datacenter or AI cluster environments
  • Familiarity with environmental and reliability testing (temperature cycling, HTOL, etc.)
