Senior ASIC​/Custom Circuit Design Engineer Memory & Mixed-Signal

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:

• 🧠 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
• 📝 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

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:

• Enjoys working on bleeding-edge nodes
• Wants visibility across architecture, circuit design, layout & silicon
• Appreciates a collaborative and high-impact hardware environment
