Senior Analog IC Design Engineer

About the Role

We are seeking a Senior Analog IC Design Engineer to develop the analog and mixed-signal circuitry powering our CapRAM-based in-memory computing technology.

You will take ownership of critical circuit blocks from specification through silicon implementation, working closely with system architects, device engineers, digital designers, and layout engineers.

Locations:

Dresden, Germany (On-site)

Austin, USA (On-site)

What you will do:

• Design and optimize transistor-level analog and mixed-signal circuits for CapRAM-based in-memory computing architectures, with a focus on power, performance, area, and precision.
• Develop precision analog building blocks, including amplifiers, comparators, biasing circuits, voltage and current references, and charge-domain circuits.
• Design ultra-low-power ADCs, memory-array peripheral circuits, and sensing and readout interfaces.
• Design and optimize power-management, supply-conditioning, and high-voltage programming circuits.
• Perform comprehensive circuit analysis and verification, including stability, noise, PVT, Monte Carlo, and post-layout simulations.
• Collaborate with system architects and device engineers to translate system requirements into circuit specifications and implementations.
• Work closely with layout engineers to ensure robust physical implementations, addressing matching, parasitics, and signal integrity.
• Support silicon bring-up, characterization, debugging, and the development of reusable analog IP.

What you should bring in:

• Bachelor's or Master's degree in Electrical Engineering, Microelectronics, or a related field.
• Minimum 5 years of hands-on industry experience in analog or mixed-signal CMOS IC design.
• Strong understanding of semiconductor device physics, transistor-level circuit operation, and analog design trade-offs.
• Solid foundation in feedback theory, small-signal AC analysis, frequency response, loop stability, compensation techniques, gain and phase margins, and settling behavior.
• Strong understanding of precision and ultra-low-power circuit techniques, including noise, mismatch, offset, linearity, and low-voltage design.
• Knowledge of capacitive and switched-capacitor circuit techniques, including charge redistribution, charge injection, leakage, and parasitic effects.
• Proficiency with EDA tools and industry-standard analog design and verification methodologies.
• Experience with at least one complete IC development cycle, including tape-out.
• Strong system-level mindset.
• Effective team communication.

Helpful but not required:

• Experience with SAR ADCs, charge-redistribution ADCs, dynamic comparators, and advanced low-power amplifier techniques.
• Experience with analog in-memory computing, emerging memory technologies, or capacitive sensing and readout circuits.
• Familiarity with high-voltage programming techniques, level shifting, LDOs, and power-supply design.
• Understanding of analog circuit nonidealities and their impact on system-level computational accuracy.
• Experience with silicon characterization, debugging, and behavioral modeling using Verilog-A, MATLAB, or Python.
• Experience working in a semiconductor startup or an early-stage technology development environment

Why us?

We offer the opportunity to develop innovative AI hardware accelerator based on SEMRON's proprietary CapRAM technology in a dynamic startup environment with challenging technical problems, opportunities for professional growth and close collaboration with a multidisciplinary team across analog, digital, device, and system engineering. You will have significant technical ownership of circuit architecture and design through silicon validation.
