Job descriptionWe are hiring High Speed Transceiver Application Engineer to join our team in San Jose. You will work in a fast-paced, cross-functional environment focused on validating high-speed modules such as 400G, 800G, and 1.6T. The role involves electrical validation, automation development, interoperability testing, and system-level debug. You will collaborate closely with hardware, firmware, and manufacturing teams to ensure robust performance across a variety of operating conditions. We welcome candidates with diverse backgrounds and experience levels who are passionate about high-speed systems and eager to contribute to cutting-edge development.
Base salary rangeis $100,000 - $170,000. The base salary offer will depend on factors such as education, experience, training, skills, qualifications, and location. This position is also eligible for a discretionary bonus, equity and a full range of medical and other benefits.
Qualifications- Master's or higher degree in Electrical Engineering, Communications Engineering, Physics, or a related field.
- Hands-on experience with high-speed transceivers such as QSFP-DD, OSFP, and AEC, and related lab instruments (e.g., oscilloscope, BERT, and VNA).
- Solid understanding of SerDes architecture, signal integrity, and high-speed link behavior, with familiarity with DSP architecture and the ability to write bring-up and tuning code.
- Strong problem-solving skills and the ability to work independently or in a team, with good communication skills and the ability to collaborate across hardware, firmware, and manufacturing teams.
- Passion for high-speed signaling, system-level validation, and continuous learning.
Job responsibilities- Characterize TIA/EML/SiPho optical components, for example TIA gain and bandwidth, AC response, and bias current and thermal settings tuning for laser and modulator optimization.
- Validate stress receiver sensitivity tests for module performance against OMA-min requirements, ensuring compliance with link budget allocations for 400G/800G/1.6T optical links.
- Build automation scripts for test execution, data collection, and analysis using Python or other programming languages, and conduct environmental and reliability stress testing, including thermal cycling, voltage margining, and soak tests.
- Analyze test results, identify root causes, and drive resolution in collaboration with cross-functional teams; support optical module bring-up, firmware validation, and vendor qualification.
- Contribute to DSP bring-up and tuning, including writing low-level code for signal processing and link optimization.
