Senior Device Electrical Engineer – High-Speed Optoelectronics - Milpitas, CA, United States
$101,675 - $169,475 USD yearly
Originally posted 5 October 2026 by the employer.
About the role
This role supports the development of advanced optoelectronic products used in optical communication test systems, with a focus on high-speed analog optoelectronic hardware.
What you'll do
- Design, analyze, and test high-speed optoelectronics devices.
- Contribute to product development from concept through production release.
- Collaborate on designs of high-speed photodiodes (>100 GHz).
- Understand and specify all aspects related to the photodiode, including epitaxial design and fabrication processes.
- Perform laboratory measurements, troubleshooting, and performance characterization in both optical and electrical domains.
- Perform simulations for device/circuit analysis and develop models to predict photodiode performance.
What you'll need
- BS or MS in Electrical Engineering or Physics.
- 8+ years of experience in electronics or device development.
- Experience designing and debugging high-speed electronic circuits.
- Experience with photodiodes, TIAs, optical receivers, RF components and analysis, or related optoelectronic components or systems.
- Experience with device and circuit simulation tools: Device physics (carrier transport, absorption, bandwidth, dark current), Optical simulation (waveguide coupling, absorption, mode overlap), RF/electrical simulation, Layout and GDS generation.
- Strong hands-on laboratory skills.
Nice to have
- Experience developing devices and electronics for high-speed optical communications or datacenter networking products.
- Experience working with 100G, 200G, 400G, or higher-speed optical communication systems.
- Familiarity with optical transceivers and receiver architectures.
- Experience with RF and microwave circuit design.
- Experience with fabrication of III-V devices.
- Experience using oscilloscopes, VNAs, BERTs, and optical test equipment.
- Familiarity with photonic integrated circuits (PICs) and advanced optoelectronic devices.
