Analog Mixed Signal Layout Engineer Jobs (NOW HIRING)

We are seeking a Senior/Principal Analog Layout Engineer to drive the layout design of complex analog and mixed-signal IP blocks that are at the heart of our advanced optical communication systems. As a key member of the Analog & Mixed-Signal (AMS) design team, you will lead layout development of critical blocks such as ADCs, DACs, PLLs, and other high-performance analog/mixed-signal circuits. You will interface closely with circuit designers, CAD/PDK teams, and other layout engineers to ensure first-pass silicon success. This is a hands-on technical role ideal for someone who thrives in a fast-paced environment and enjoys mentoring others while contributing directly to cutting-edge chip development.

Locations: Irvine, CA (HQ) or San Jose, CA
Key Responsibilities
Lead and own the physical layout design of complex analog/mixed-signal macros (e.g., ADCs, DACs, PLLs), from floor planning through final verification
Collaborate closely with schematic designers to create optimal layout solutions considering performance, matching, symmetry, and reliability
Mentor and guide junior layout engineers/contractors across multiple time zones, enforcing best practices in layout design and verification
Perform and debug full hierarchy LVS, DRC, PERC, ERC, and other signoff checks using industry-standard tools (Pegasus, Calibre, etc.)
Contribute to chip-level planning including top-level floor planning, block integration, power grid implementation, and signal routing
Participate in layout design reviews and provide technical leadership for layout quality, verification completeness, and schedule adherence
Support automation initiatives through scripting and tool customization (SKILL, TCL, Python is a plus)
Required Qualifications
Minimum 10+ years of hands-on analog/mixed-signal layout design experience and in advanced CMOS/FinFET technologies
Proven track record of top-level integration IP layout macros and preparing IPs for handoff to Physical Design
Proven leadership in owning major IP layout macros or full-chip-level layout at FinFET nodes (TSMC preferred)
At least 1 year of experience with TSMC FinFET process nodes (N3, N5, N7, or N16)
Deep understanding of device physics, layout-dependent effects (LOD, WPE, OSE, LDE, etc.), and their impact on circuit performance
Strong expertise in layout best practices for device matching, noise isolation, ESD protection, symmetry, and parasitic minimization
Proficiency in floor planning, hierarchical block integration, routing strategy, and power/ground grid design
Expertise with Cadence Virtuoso, Calibre, Pegasus, and other layout and verification tools
Familiarity with layout verification flows, including LVS, DRC, PERC, Density, DFM, ERC, and Antenna rules
Experience working in collaborative environments with international and remote teams
Strong documentation and communication skills with the ability to clearly present layout trade-offs and status to cross-functional teams
Experience using revision control systems for layout design management
Preferred Qualifications
Exposure to optical or high-speed analog interfaces is a strong plus
Working knowledge of SKILL, TCL, or Python for layout automation or design flow optimization
Proven ability to collaborate with international teams (U.S., Canada, Argentina)
Strong organizational skills with high attention to detail and follow-through
Ability to multi-task and prioritize in a fast-paced, dynamic environment
Proactive, eager-to-learn mindset with excellent problem-solving skills
What We Offer
The chance to play a foundational role at a high-growth semiconductor start-up
Exposure to a wide variety of cross functional teams
A collaborative, international team culture where ideas and initiative are valued
The opportunity to grow alongside Celero as we scale and shape the future of our industry
A foundational role at a fast-growing semiconductor start-up shaping the future of AI and data center connectivity
Annual Base Salary Range for US: $150,000 - $250,000 (The final offer will be determined based on job-related skills, experience, qualifications, and location.)
