Job summary

Mach Industries in Huntington Beach, CA seeks a Principal Systems Engineer to lead the use of modeling and simulation across the aircraft design process. You will develop integrated aircraft-level simulations, evaluate design alternatives, and translate analysis into clear engineering decisions.

The role requires close collaboration with the aerodynamics, structures, propulsion, electrical, controls, and vehicle systems teams.

Qualifications

Bachelor's degree in aerospace, mechanical, electrical, or related discipline.
Significant experience developing or applying aircraft-level models and simulations.
Strong understanding of aircraft performance, flight mechanics, dynamics and multidisciplinary system interactions.
Experience integrating models from aerodynamics, structures, propulsion, electrical, controls, or thermal disciplines.
Proficiency with MATLAB/Simulink, Python, C/C++, or equivalent platforms.
Experience conducting trade studies, parameter sweeps, sensitivity analyses, uncertainty quantification, or optimization.
Demonstrated ability to convert simulation results into actionable aircraft design recommendations.
Experience with model verification, validation, test correlation, and configuration control.
Strong technical leadership and cross-functional communication skills.

Responsibilities

Own the architecture, development, and validation of integrated aircraft simulations.
Use simulation to guide aircraft configuration, subsystem sizing, requirements, and design trade studies.
Integrate aerodynamic, structural, propulsion, electrical, mass-properties, controls, and mission-performance models.
Lead multidisciplinary design optimization and sensitivity analyses.
Quantify design margins, uncertainty, risk, and system-level impacts of proposed changes.
Define simulation fidelity requirements appropriate to each phase of development.
Establish model verification, validation, configuration-management, and documentation practices.
Correlate simulation results with component tests, ground tests, and flight-test data.
Develop representative mission profiles and evaluate aircraft performance across operating conditions.
Identify system interactions, integration risks, and performance constraints early in the design cycle.
Present recommendations and trade-offs to technical leadership and program stakeholders.
Mentor engineers and establish best practices for simulation-driven aircraft development.
Support requirements development, architecture reviews, design reviews, and certification activities.
