Job Summary
Your mission
The future of AI computing is light not electrons. is building photonic processing systems that compute with light delivering a scalable energy-efficient alternative to transistor-based architectures for next-generation AI and HPC applications.
As Senior GHz Analog & Mixed-Signal Engineer (m/f/d) you are the architect of the high-speed electronic signal paths in the GHz-range that make photonic computing real. You will design simulate and validate circuits that interface directly with cutting-edge silicon photonic devices custom ASICs and advanced 2.5D/3D interposer platforms. Working at the intersection of RF electronics electro-optics and semiconductor heterogeneous integration you will turn individual high-performance components into unified scalable subsystems.
Your Responsibilities
- High-Speed Analog & Mixed-Signal Design: Specify design and simulate GHz-band circuits including TIAs ADC/DAC front-ends amplifiers and PLLs optimizing for noise linearity jitter bandwidth and power efficiency using tools such as SPICE SpectreRF and ADS.
- Electronic-Photonic Co-Design: Define and optimize electrical-optical impedance matching biasing and signal conditioning for silicon photonic components including modulators photodetectors and waveguide interfaces.
- Interposer & Advanced Packaging Integration: Develop and validate 2.5D/3D integration architectures using interposers and chiplets; co-simulate RF parasitics TSV routing and thermal behavior to ensure signal integrity across heterogeneous boundaries.
- ASIC Collaboration: Partner with ASIC designers to define high-speed interface requirements and support SerDes CDR and mixed-signal block integration.
- Lab Bring-Up & Validation: Lead hands-on characterization of electro-optic bandwidth eye diagrams jitter noise spectra and system-level behavior using oscilloscopes VNAs BERTs and spectrum analyzers.
- Innovation & IP Contribution: Propose novel analog architectures and co-integration strategies that push beyond conventional design limits contributing to IP portfolio and next-generation photonic processor roadmap.
Your profile
- Educational Foundation:M.S. or Ph.D. in Electrical Engineering Physics Microsystems Engineering or a related technical field.
- Industry Expertise:5 years designing analog/mixed-signal circuits in the 120 GHz range with strong command of SPICE/Spectre ADS HFSS and S-parameter/EM co-simulation.
- Electro-Optic Experience:Hands-on background integrating electronics with silicon photonic or optoelectronic components modulators photodiodes optical packaging is a strong advantage.
- Packaging & SI/PI Know-How:Demonstrated experience with high-speed PCB design signal and power integrity analysis and advanced packaging concepts (CoWoS EMIB or similar).
- Analytical Toolset:Familiarity with Python or MATLAB for measurement automation and data analysis; experience defining test SOPs for reproducibility.
- Language:Fluent English required; German or another European language is a plus.
