Circuit Design Engineer for AI Training

Apply hands-on circuit-design expertise to create, solve, review, and validate engineering tasks that help improve AI systems. This remote contract role focuses on real-world analog, digital, power, mixed-signal, and RF design work, including simulation, programmatic EDA workflows, verification, and Python-based automation. Key Responsibilities

• Design, analyze, and validate analog, digital, power, mixed-signal, or RF circuits.
• Translate electrical requirements into schematics, netlists, models, HDL, constraints, and simulation inputs.
• Run circuit simulation, synthesis, verification, and related workflows with command-line-accessible tools.
• Use Python to generate inputs, automate simulations, run parameter sweeps, control instruments, and analyze results.
• Evaluate voltage, current, power, gain, bandwidth, impedance, noise, timing, stability, thermal behavior, and other relevant outputs.
• Perform corner, tolerance, worst-case, transient, frequency-domain, and Monte Carlo analyses when appropriate.
• Compare simulated behavior with analytical calculations and physical measurements.
• Diagnose issues involving component selection, parasitics, layout, power integrity, signal integrity, thermal behavior, interfaces, and manufacturing.
• Review AI-generated circuit solutions for incorrect assumptions, invalid configurations, and unsupported conclusions.
• Develop reproducible reference solutions and automated verification checks.

• MS or PhD in Electrical Engineering or a closely related field, or a BS in Electrical Engineering plus 1 to 2 years of relevant professional circuit-design experience.
• Meaningful experience designing analog, digital, power, mixed-signal, or RF circuits.
• Experience with designs that were fabricated, integrated, shipped, or taped out. Simulation-only academic experience is not sufficient.
• Practical proficiency with Python.
• Experience with at least one EDA, circuit-simulation, PCB, HDL, synthesis, or verification tool that supports command-line workflows, scripting, text-based inputs, or a programmatic API.
• Strong understanding of circuit behavior, component selection, tolerances, failure modes, and design trade-offs.
• Experience with hardware bring-up, laboratory validation, design verification, or post-fabrication debugging.
• Ability to clearly explain circuit behavior and technical decisions.
• Relevant tools may include ngspice, Xyce, Yosys, Verilator, and KiCad.

• Global, fully remote independent contractor engagement.
• Approximately 15 hours per week.
• Flexible schedule, with freedom to choose working hours and days, including weekends if desired.

• $80 to $130 per hour.
