Principal High-Speed Analog Layout Design Engineer

Job description

We are seeking a **High-Speed Analog Layout Design 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. **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.)*
