Job description

Palitronica is seeking a Principal RF Modeling & Characterization Engineer to develop the predictive RF models and characterization methods needed to understand and optimize Anvil's RF measurement system.

This role will bridge RF theory, simulation and physical measurement. You will develop adaptive RF system models that explain system behavior, extract critical parameters from measured data, and maintain correlation with real hardware through continuous parameter extraction and model optimization. These models will enable real-time characterization and continuous performance tracking of our measurement system while measurements are being executed.

Responsibilities

• Own the development of physical and electrical models for Anvil's RF modules, interconnects and measurement paths, from individual building blocks through end-to-end system behaviour.
• Develop and validate RF network models using S-parameters, transmission-line theory and other appropriate modeling techniques.
• Develop methods for parameter extraction, model fitting and optimization using measured RF data.
• Correlate simulations with RF measurements, identify sources of discrepancy, and continuously improve model fidelity.
• Perform sensitivity, tolerance and trade-off analysis to identify the parameters that most strongly affect system performance and measurement repeatability.
• Model the impact of temperature, environmental conditions, interfaces and other physical effects where they materially affect RF behaviour.
• Develop characterization experiments and measurement strategies required to validate models and resolve technical uncertainty.
• Develop tools and automation for RF modeling, characterization, data analysis and optimization.
• Work closely with RF measurement, hardware, mechanical, and systems engineers to develop, validate, and refine system models, ensuring continuous correlation between model predictions and measured hardware performance.
• Establish reusable modeling methodologies, reference models and technical documentation that become part of Anvil's engineering foundation.

Required Qualifications

• Bachelor's, Master's or PhD in Electrical Engineering, Applied Physics, Microwave Engineering or a related discipline.
• Significant industry experience in RF/microwave modeling, characterization or measurement, with demonstrated principal-level technical depth.
• Deep understanding of S-parameters, scattering matrices, transmission lines, impedance, RF networks and passive RF structures.
• Strong experience with RF parameter extraction, model optimization and simulation-to-measurement correlation.
• Experience with RF/microwave simulation tools such as ADS, HFSS, CST, EMPro, AWR, SystemVue or equivalent.
• Hands-on experience using VNAs and interpreting high-quality RF measurement data.
• Experience developing circuit/analytical/numerical models of complex RF systems or interconnected RF building blocks.
• Proficiency with Python, MATLAB or similar tools for analysis, automation and model development.
• Strong experimental and analytical problem-solving skills, including the ability to isolate unexplained physical behaviour and design experiments to resolve it.

Nice to Have

• Experience with RF test and measurement equipment or instrumentation.
• Experience with RF fixtures, connectors, switching networks, probing systems or high-density interconnects.
• Experience with multi-physics, thermal or environmentally dependent RF modeling.
• Experience developing internal RF CAD/CAT, modeling or characterization tools.

Export Control, Controlled Goods & Security Eligibility

• This position requires direct or indirect access to hardware, software, or technical information controlled under the Canadian Export Control List, the Canadian Controlled Goods Program, the Canadian Industrial Security Program, the U.S. International Traffic in Arms Regulations (ITAR), and/or the U.S. Export Administration Regulations (EAR).
• All applicants must be eligible or able to obtain authorization for such access, including eligibility for the Canadian Controlled Goods Program, and must be able to obtain a Canadian NATO Secret clearance.
