Mixed-Signal Behavioral Modeling Engineer

The Role We are seeking a Mixed‑Signal Behavioral Modeling Engineer to own the creation of behavioral modeling and drive mixed‑signal verification methodology from the ground up. You will be part of a collaborative design team developing state‑of‑the‑art mixed‑signal SoCs to be hosted on some of the largest, most powerful, rapidly designed and manufactured satellites ever deployed in space. Your work will directly influence top‑level integration and silicon tapeout success. This is a high‑impact, technical role with significant ownership across modeling, methodology, verification, and cross‑functional alignment with RF, analog, and digital teams. Responsibilities Develop high‑level behavioral models for analog and mixed‑signal IP (ADCs, DACs, PLLs, LDOs, RF front‑end blocks, biasing, amplifiers, etc.). Create abstracted models using Verilog, Verilog‑AMS, or SystemVerilog. Develop regression infrastructure and mixed‑signal testbenches enabling co‑simulation (digital + analog). Integrate AMS models into digital verification environments (UVM‑based). Define and build the mixed‑signal verification methodology for top‑level SoC and subsystem verification. Support architectural exploration through early‑phase modeling and system‑level simulations. Collaborate with analog/RF designers to capture real‑world analog behaviors and map them into accurate behavioral abstractions. Work with digital and verification teams to ensure seamless integration of AMS models. Provide modeling and verification insights during architectural reviews, PDR/CDR, and silicon bring‑up. Act as technical lead and subject‑matter expert. Required Qualifications M.S. or Ph.D. in Electrical Engineering, Computer Engineering, or related field. 2+ years of experience in analog/mixed‑signal modeling and/or AMS verification. Hands‑on experience with SystemVerilog, Verilog‑AMS, wreal/RNM, or equivalent modeling languages. Strong understanding of analog/mixed‑signal circuits (PLLs, LDOs, ADC/DACs, RF/IF paths, clocking, amplifiers). Experience with mixed‑signal co‑simulation environments (Cadence AMS Designer, Synopsys VCS AMS, or similar). Preferred Qualifications Experience building AMS verification methodologies from scratch. Familiarity with UVM‑based verification and digital design flows. Knowledge of signal processing theory, RF system modeling, or communication systems. Experience with MATLAB/Simulink, Python modeling, or SystemC AMS for high‑level architectural modeling. Experience working in cross‑functional, geographically distributed teams. Compensation and Benefits Base salary range: $130,000 – $180,000 + equity in the company. Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level. Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks. Export Compliance As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.” The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. 120.15 or otherwise eligible for a federally issued export control license. 120.15 or otherwise eligible for a federally issued export control license.
