Modeling Design, Staff Engineer

Job Title

Modeling Design, Staff Engineer

Role Summary

The Modeling Design Staff Engineer develops and validates models for analog, digital, and mixed-signal circuits used in Lattice FPGAs. This role partners with architecture, design, and verification teams to ensure model accuracy, performance, and usability across product releases.

Works as a technical lead and mentor for circuit modeling engineers and coordinates cross-functional feedback to improve model quality and performance.

Experience Level

Senior - typically requires several years of applied experience; the posting specifies 5+ years of relevant experience.

Responsibilities

Primary responsibilities include developing, validating, and optimizing circuit models and guiding their consumption by internal teams.

• Develop and validate models for analog, digital, and mixed-signal circuits used in FPGA products.
• Perform digital and mixed-signal simulation and analysis using Verilog, VHDL, SystemVerilog, SPICE, and similar tools.
• Provide technical leadership and mentorship to circuit modeling engineers.
• Collaborate with design and architecture teams to capture circuit requirements and translate them into accurate models.
• Analyze simulation results and iterate on models to improve accuracy, performance, and efficiency.
• Document modeling processes, assumptions, and results for stakeholders.
• Optimize models for runtime performance and integration with verification flows.
• Keep current with modeling techniques, tools, and best practices.

Requirements

Must-have technical skills and experience; items marked as "nice-to-have" are additional strengths.

• Proven experience in circuit modeling and simulation (analog, digital, mixed-signal).
• Proficiency with simulation tools such as SPICE, Verilog, VHDL, and SystemVerilog.
• Experience with higher-level modeling (SystemC) and SystemVerilog-based modeling techniques.
• Strong analytical and problem-solving skills; ability to interpret simulation data and drive model improvements.
• Demonstrated ability to lead technical work and mentor junior engineers; strong communication and collaboration skills.
• Experience documenting modeling methodologies and delivering results to internal customers.
• Nice-to-have: experience with data analysis and visualization tools to support model validation.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering. The posting specifies 5+ years of relevant experience in circuit modeling and simulation.
