The RoleWe 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 rapidly 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 leader 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 for this role is $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
If you don't meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!
