Tasks
3Brain is looking for a full-time Senior Analog ASIC Design Engineer for its Swiss office to strengthen its R&D team and contribute to the next generations of our CMOS‑based biological sensor platforms. The candidate will join a group of mixed‑signal and digital ASIC engineers and will focus on designing, optimizing, and validating high‑performance analog and mixed‑signal circuits tailored for large‑scale sensor arrays.
Main responsibilities:
Design of analog /mixed‑signal circuit blocks for CMOS biosensor products
Implementation and validation of analog circuits using modern CAD tools.
Development of transistor‑level schematics, simulations, corner and Monte‑Carlo analyses, modelling, and layout.
Extraction, verification, and optimization of circuits to meet performance, area, and power requirements.
Documentation of design methods, specifications, architecture decisions, and verification with digital, packaging, and system teams to ensure full‑chip integration and system‑level performance.
Requirements
Required Qualifications
5+ years of professional experience in analog or mixed‑signal ASIC design.
BSc/MSc/PhD in Electrical Engineering, Microelectronics, or related field.
Core Expertise: Analog IC design fundamentals; Low‑noise and low‑power analog front‑end design; Stability, noise, mismatch, and linearity analysis; Device‑level simulation and modelling; Analog layout best practices
Proficiency with analog design workflows (i.e. schematics, state-of-the-art SPICE simulations, extraction tools, post-layout simulation, etc.)
Good knowledge of scripting (, MATLAB, or SKILL).
Fluency in English.
Strong team spirit, initiative, and ability to work independently in a multicultural environment.
Applicant must be authorized to work in Switzerland without employer sponsorship (e.g., EU/EFTA citizen, Swiss C permit, or family member of an EU/EFTA citizen with a work‑authorized residence card).
Additional Qualifications
Experience with mixed‑signal integration and top‑level verification.
Experience with ADC/DAC architectures and characterization.
Experience with physical verification (LVS/DRC, electromigration).
Knowledge of CMOS sensor interfaces or biomedical instrumentation is a strong plus.
Understanding of digital design basics and ability to collaborate with digital teams.
Benefits
A dynamic and stimulating work environment driven by a desire to build transformational technologies to help others.
A young, fast-growing company with plenty of opportunities for personal growth and development.
Working place: Pfäffikon SZ, Switzerland. It’s a beautiful lakeside village just outside of Zurich, the country’s main cultural, financial and business center.
