About The Position

Celero Communication Inc. is seeking a Principal/Senior Analog Layout Engineer to lead the physical layout design of complex analog and mixed-signal IP blocks for advanced optical communication systems. As part of the Analog & Mixed-Signal design team, the engineer will work closely with circuit designers, CAD/PDK teams, and other layout engineers to support first-pass silicon success. This is a hands-on technical role that includes mentoring other engineers and contributing to chip development in a fast-paced semiconductor start-up environment.

The role covers layout development for blocks such as ADCs, DACs, and PLLs, from floor planning through final verification. It also contributes to chip-level planning, block integration, power-grid implementation, signal routing, and automation initiatives. The position provides technical leadership for layout quality, verification completeness, and schedule adherence.

Requirements

• At least 10 years of hands-on analog/mixed-signal layout design experience in advanced CMOS/FinFET technologies.
• A proven track record of top-level integration of 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 is preferred.
• At least 1 year of experience with TSMC FinFET process nodes N3, N5, N7, or N16.
• Deep understanding of device physics and layout-dependent effects, including LOD, WPE, OSE, and LDE, and their impact on circuit performance.
• Strong expertise in layout 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 collaboratively with international and remote teams.
• Strong documentation and communication skills, including the ability to clearly present layout trade-offs and status to cross-functional teams.
• Experience using revision-control systems for layout design management.

Nice To Haves

• Exposure to optical or high-speed analog interfaces.
• Working knowledge of SKILL, TCL, or Python for layout automation or design-flow optimization.
• Proven ability to collaborate with international teams in the U.S., Canada, and Argentina.
• Strong organizational skills, attention to detail, and follow-through.
• Ability to multitask and prioritize in a fast-paced, dynamic environment.
• A proactive, eager-to-learn mindset and excellent problem-solving skills.

Responsibilities

• Lead and own physical layout design of complex analog/mixed-signal macros, such as ADCs, DACs, and PLLs, from floor planning through final verification.
• Collaborate with schematic designers to develop layout solutions that account for performance, matching, symmetry, and reliability.
• Mentor and guide junior layout engineers and contractors across multiple time zones, and reinforce layout design and verification best practices.
• Perform and debug full-hierarchy LVS, DRC, PERC, ERC, and other signoff checks using tools such as Pegasus and Calibre.
• 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.

Benefits

• Opportunity to play a foundational role at a high-growth semiconductor start-up.
• Exposure to a wide variety of cross-functional teams.
• Collaborative international team culture where ideas and initiative are valued.
• Opportunity to grow alongside Celero as it scales and shapes the industry.
