Computational Scientist – FDTD

About the role:

We’re looking for a highly skilled Computational Scientist with deep expertise in computational electromagnetics, numerical methods, scientific computing, and mathematical modeling.

This role will focus on the research, development, validation, and optimization of finite-difference time-domain algorithms for modeling complex electromagnetic phenomena. 

This is a highly specialized research role centered on advancing FDTD methods, improving numerical accuracy and stability, evaluating algorithmic tradeoffs, and developing computationally efficient implementations for high-performance simulation environments. 

What you'll do:

• Conduct in-depth research and development of FDTD algorithms for computational electromagnetics. 

• Translate electromagnetic theory and advanced mathematical concepts into robust, discrete computational formulations. 

• Perform validation and accuracy studies against analytical solutions, published benchmarks, and established simulation methods. 

• Document research findings, algorithm designs, validation results, and technical recommendations for internal stakeholders. 

• Contribute to long-term research direction for advanced electromagnetic simulation capabilities. 

Qualifications:

• Education/Experience: Advanced degree (Master’s or PhD) in Physics, Mathematics, Computer Engineering, Computer Science, or a related field with a strong focus on computational electromagnetics. 

• FDTD Expertise: Strong experience with finite-difference time-domain methods, Maxwell’s equations, wave propagation, and numerical electromagnetics. 

• Research Ability: Ability to evaluate published methods, compare algorithmic approaches, and develop novel or improved computational techniques. 

• Mathematical Modeling: Proficiency in advanced calculus, vector calculus, differential equations, linear algebra, and modeling of physical phenomena. 

• Programming: Python, Julia, C/C++, MATLAB. 

• Communication: Ability to clearly articulate research findings to both technical and non-technical leadership. 

• Exposure to hardware acceleration, HPC, or GPU/FPGA technologies is beneficial. 

• Startup experience 

• Government clearance is preferred 

Compensation Range: $150,000–$220,000 per year (California). This range represents the anticipated base pay for this role; the final offer may vary based on qualifications, experience, and location.

Benefits:

• Medical, Dental, & Vision - 100% covered premiums
• Equity - Stock Options
• 401(k) match
• WFH Hardware
