Remote Biomedical Design Engineer Jobs in California

Principal High-Speed Analog Layout Design Engineer
About the Role
Celero Communication Inc. is an exciting and fast-growing start-up in the semiconductor industry, pushing boundaries with innovative technologies that power the world's most advanced AI and data center infrastructure. As we scale rapidly, we are looking for a driven and resourceful High-Speed Analog Layout Engineer to be the backbone of our daily operations and a key partner in shaping our company culture.
We are seeking a Principal/Senior 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.
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 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: $200,000 - $300,000 (The final offer will be determined based on job-related skills, experience, qualifications, and location.)
