Encore Semi • Fort Collins, CO

23h

About The Position

Encore Semi, Inc. is seeking an experienced Analog/Mixed-Signal IC Design Engineer to architect and tape out high-speed data converters (ADCs/DACs) in advanced FinFET nodes from 7nm down to 3nm. The role owns the full design cycle, from system architecture through post-silicon validation, for next-generation HPC, AI, and communications hardware. Positions are listed for San Jose, California; San Diego, California; or remote within the USA. Full-time and contract options are available. US citizenship or permanent resident status is required.

Requirements

• M.S. or Ph.D. in Electrical Engineering or a related field.
• 10+ years of hands-on high-speed data converter design experience and successful silicon tape-outs.
• Proven track record in advanced FinFET nodes, including 3nm, 5nm, or 7nm.
• Strong command of FinFET-specific design constraints, including fin quantization, degraded gm/gds, and 3D RC extraction.
• Experience with Cadence Virtuoso, Spectre/PrimeSim, and Calibre PEX/Quantus.
• US citizenship or permanent resident (GC holder) status.

Responsibilities

• Architect and design multi-GS/s ADC/DAC architectures, including Time-Interleaved SAR, Pipeline, Flash, or RF-DACs.
• Deliver transistor-level circuits such as track-and-hold circuits, comparators, low-jitter clock paths, and bias networks in 7nm–3nm FinFET processes.
• Implement background and foreground digital calibration for offset, gain, timing skew, and linearity.
• Supervise layout to mitigate layout-dependent effects (LDE), parasitics, electromigration, and self-heating.
• Lead post-silicon lab bring-up, bench testing, and model-to-hardware correlation.

Benefits

• 15 days of PTO per calendar year.
• 10 paid holidays per calendar year.
• Comprehensive medical benefits; the company covers 80% of premiums for employees and dependents.
• Dental and vision benefits; the company covers 50% of premiums for employees and dependents.
