• Develop RF and microwave circuits from DC to 100 GHz and beyond.
• Design low‑noise signal conditioning, amplification, control, and power management circuits.
• Perform signal integrity, power integrity, and electromagnetic compatibility analyses.
• Design and characterize photodiode‑based receiver chains, including:
  • Focusing optics
  • Photodiodes
  • Transimpedance amplifiers (TIAs)
  • Distributed amplifiers
  • Receiver front‑end electronics
  • Optical detection and acquisition systems
• Perform HFSS‑based analog simulations and high‑speed signal‑path analysis.
• Travel Requirements:
  Up to 10% of Travel is required.

• MS, or PhD in Electrical Engineering or related field.
• 15+ years of experience developing complex electronic products.
• Deep expertise in analog circuit design.
• Strong RF and high‑speed electronics design experience.
• Demonstrated experience designing photodiode‑based receiver systems.
• Experience with optical design and concepts.
• Experience with optoelectronic hardware development.
• Strong proficiency with circuit simulation and modeling tools.
• Expertise in laboratory characterization, debugging, and root‑cause analysis.
• Track record of bringing complex products from concept through production.

• Experience developing electronics and optoelectronic hardware for high‑speed optical communications and datacenter networking applications.
• Experience with 100G, 200G, 400G, 800G, or higher‑speed optical communication systems.
• Experience with optical transceivers, coherent optics, and photonic integrated circuits (PICs).
• Experience with MMIC components and capabilities.
• Experience with RF amplifier design and topologies.
• Experience with semiconductor optoelectronic devices and device characterization.
• Experience with optical test and measurement systems.
• Familiarity with high‑performance instrumentation including oscilloscopes, vector network analyzers (VNAs), and optical/RF spectrum analyzers; TDECQ testing.
