Senior ASIC / Custom Circuit Design Engineer Memory & Mixed-Signal
📍 Zurich | 🧠 Deep Tech | Advanced Nodes | 🏠 Hybrid
We are partnering with an innovative Zürich-based tech company who are seeking a motivated Senior ASIC / Custom Circuit Design Engineer to design high-performance, low-power custom-digital and memory-centric circuits used at the heart of their compute architecture. This is a full-time permanently employed position.
If you love circuit design, debugging silicon behaviour, and optimizing for power, speed, and stability this is for you. 👇
🚀 What you will be doing
You will take designs from concept implementation characterization silicon bring-up. Key responsibilities include:
* 🧩 Designing custom circuits for SRAM, register files, datapaths & periphery
* 🧠 Architecting and implementing blocks on advanced nodes (FinFET, sub-10nm)
* 📏 Running corner, Monte-Carlo, variation, and stability simulations
* 🤝 Working closely with layout, digital, backend, DFT & verification teams
* 🚦 Reviewing extraction results, debugging EM/IR issues & proposing fixes
* 📐 Defining clean integration boundaries for digital-on-top environments
* 🧬 Supporting silicon correlation (bring-up, ATE analysis, errata handling)
* 🔧 Creating reusable design kits, models, testbenches & automation scripts
* 📝 Documenting methodologies and improving internal design flows
🌟 What you willbring (must-haves)
The essentials for success in this role:
* 5+ years in custom digital, mixed-signal, or memory (SRAM) design
* Proven ownership of blocks through full design cycles
* Strong understanding of FinFET behaviour (variation, leakage, stability, periphery trade-offs)
* Hands-on experience designing memory sub-systems, datapaths, or register files
* Ability to analyze extraction/PEX results and work closely with layout
* Solid foundation in performance, power, and area (PPA) optimization
* Comfort with simulation flows, timing behaviour, parasitics, and correlation
* Good scripting knowledge (Python or Tcl) for automation
* Clear communication & strong documentation habits
Nice to have (bonus skills)
These are not required, but they will help you stand out:
* Experience with memory compilers or memory characterization flows
* DTCO/STCO exposure (device bitcell periphery understanding)
* Background in EM/IR analysis or reliability considerations
* Familiarity with custom-digital verification environments
* Knowledge of test structures, MBIST/scan concepts, or redundancy features
* A passion for hardware optimization and deep-dive debugging
🧩 Who this role suits
Someone who:
* Loves hands-on transistor-level + custom-digital design
* Enjoys working on bleeding-edge nodes
* Wants visibility across architecture, circuit design, layout & silicon
* Appreciates a collaborative and high-impact hardware environment
