Modeling & Simulation Engineer (Internship or PT)

Red Cell Partners • Los Angeles, CA

4d • $70 - $80

About The Position

Dash 2 Dynamics (D2), an incubated company of Red Cell Partners, is developing advanced communications systems that integrate plasma physics, radio-frequency engineering, and novel antenna architectures. Its work aims to overcome limits of conventional antennas and enable smaller, more wideband, and more resilient communications in demanding environments, taking technology from laboratory research through prototyping, modeling and testing, qualification, and operational deployment.

D2 seeks a part-time Modeling & Simulation Engineer or advanced engineering intern to support the design of plasma-enabled antennas and next-generation communications hardware. The role builds electromagnetic and multiphysics models, conducts design trade studies, and connects simulations to laboratory measurements to inform design decisions. It is a hands-on position on a multidisciplinary team working across electromagnetics, materials, electronics, plasma science, and product development.

Requirements

• Currently pursuing or recently completed an advanced degree in Electrical Engineering, Applied Physics, Mechanical Engineering, Aerospace Engineering, Computational Science, or a related field.
• Coursework or project experience in electromagnetics, antennas, RF engineering, numerical methods, plasma physics, or related physics-based modeling.
• Significant hands-on experience with at least one finite element modeling simulation environment.
• Ability to meet requirements associated with work on U.S. government and national-security programs.

Nice To Haves

• Experience with the COMSOL Multiphysics Plasma Module.
• Experience modeling antennas, RF structures, plasmas, resonators, high-voltage fields, or coupled multiphysics systems.
• Strong fundamental knowledge of low-temperature RF glow discharge physics.
• Familiarity with S-parameters, impedance matching, radiation patterns, meshing, solver convergence, uncertainty, and model validation.
• Ability to assess model quality through convergence, sensitivity, validation, and careful documentation of assumptions.
• Ability to translate analysis into concise findings and actionable design recommendations.
• Strong initiative, intellectual honesty, and comfort working on open-ended technical problems.
• Laboratory experience with RF test equipment, such as a vector network analyzer, spectrum analyzer, oscilloscope, RF source, or automated data acquisition.
• Active U.S. security clearance or eligibility to obtain one.

Responsibilities

• Build coupled electromagnetic–plasma models of plasma chambers, antennas, matching networks, and enclosures, accounting for plasma density, collision frequency, and discharge conditions.
• Run frequency-domain, time-domain, and coupled-physics analyses of fields, losses, and scaling behavior, using appropriate boundary conditions, meshing, and convergence checks.
• Plan parameter sweeps and trade studies across geometry, materials, plasma properties, control schemes, and packaging constraints.
• Screen concepts, quantify uncertainty, and develop reusable, scriptable workflows for evaluating product configurations and frequency bands.
• Translate simulation findings into recommendations about designs to build and test.
• Work with RF, electrical, mechanical, and test engineers to design experiments and compare simulation predictions with measurements of S-parameters, radiation patterns, and plasma behavior.
• Conduct post-test analysis and root-cause investigations when hardware measurements differ from predictions; establish uncertainty bounds and traceable model records.
• Prepare technical notes, figures, and design-review materials to inform architecture and prototype decisions.
• Own analysis tasks and keep models, scripts, inputs, and results reproducible while clearly communicating confidence, limitations, and next steps.

Benefits

• Career-track opportunity with potential for rapid advancement based on strong performance as the firm grows (full-time roles).
• 100% employer-paid comprehensive health care, including medical, dental, and vision coverage for employees and their families (full-time roles).
• Paid maternity and paternity leave for 14 weeks at normal pay (full-time roles).
• Unlimited PTO with management approval (full-time roles).
• Professional development and continued-learning opportunities (full-time roles).
• Optional 401(k), FSA, and equity incentives (full-time roles).
• Mental health benefits through Tara Mind (full-time roles).
• Cost-effective GLP-1 solutions through Crux (full-time roles).
