Mixed-Signal Behavioral Modeling Engineer - Remote

Mixed-Signal Behavioral Modeling Engineer

United States – Remote

K2 is building the largest and highest‑power satellites ever flown, unlocking performance levels previously out of reach across every orbit. With $450M from leading investors and $500M in signed contracts, we are mass‑producing state‑of‑the‑art satellite platforms for missions from LEO to deep space.

The rise of heavy‑lift launch vehicles is shifting the industry to one of mass abundance. K2 satellites are engineered to survive harsh radiation environments and leverage today’s and tomorrow’s massive rockets, delivering unmatched capability at constellation scale and across multiple orbits.

With multiple launches planned through 2026 and 2027, we are building bigger to develop the solar system and become a Kardashev Type II civilization. This fast‑paced, groundbreaking Series‑C space startup seeks a driven individual excited to contribute.

We are searching for a Mixed‑Signal Behavioral Modeling Engineer to own the creation of behavioral modeling and develop mixed‑signal verification methodology from the ground up. You will work on state‑of‑the‑art mixed‑signal SoCs destined for the largest, most powerful satellites ever deployed.

• Develop high‑level behavioral models for analog and mixed‑signal IP (ADCs, DACs, PLLs, LDOs, RF front‑end blocks, biasing amplifiers, etc.).
• Build regression infrastructure and mixed‑signal test benches 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 a technical leader and subject‑matter expert.

• M.S. or Ph.D. in Electrical Engineering, Computer Engineering, or related field.
• Minimum 2 years of experience in analog/mixed‑signal modeling and/or AMS verification.
• Hands‑on experience with System Verilog, Verilog‑AMS, VHDL‑AMS, 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).

• 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 System
  
  C‑AMS for high‑level architectural modeling.
• Experience working in cross‑functional, geographically distributed teams.

• Base salary range: $130,000 – $180,000 + equity.
• Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and other perks.
