Principal Systems Engineer

Honeywell Aerospace • Torrance, CA • 2h ago

Honeywell Aerospace is seeking an experienced Principal Systems Engineer specializing in Environmental Control System (ECS) modeling and analysis. This role focuses on developing and validating ECS system-level models with an emphasis on steady state performance, thermodynamics, and aircraft environmental/thermal management. The ideal candidate will bring deep technical expertise and the ability to drive system-level analysis that supports design, integration, and customer requirements.

Key Responsibilities

Lead the creation, enhancement, and maintenance of ECS system-level models for steady-state performance prediction, trade studies, and design optimization.

Conduct system architecture studies, evaluating alternative ECS configurations, subsystem interactions, load paths, and integration strategies.

Perform thermodynamic and fluid-flow analysis of air cycle systems, air-conditioning packs, bleed air systems, PTMS, NGS, and related ECS subsystems.

Demonstrate strong expertise in VCS modeling and analysis through steady-state model development, architecture trade studies, component-to-system integration assessments, and data-driven design insights.

Serve as the proposal technical lead, defining system performance baselines, assessing technical risks, and identifying value-engineering opportunities for new business pursuits.

Conduct steady-state simulations across environmental, load, and failure scenarios, and define system operating points, boundary conditions, and performance criteria aligned with aircraft requirements.

Generate clear engineering recommendations that support decisions for system architecture, component sizing, control strategies, and integration.

Support component and subsystem teams with analytical inputs, performance sensitivities, and system-level impact assessments.

Interface with internal and external customers to present results, participate in technical reviews, and justify analytical methods.

Validate steady-state models through correlation with test data and support verification and validation strategy development.

Mentor junior engineers and contribute to advancing ECS modeling tools, methods, and best practices.

Ensure compliance with Honeywell engineering processes, aerospace standards, and program deliverables.

Qualifications

Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related technical field (Master's or PhD preferred).

10-15+ years of experience in aerospace systems engineering, thermal systems, or ECS-related analysis.

Strong foundation in thermodynamics, heat transfer, and fluid mechanics.

Proficiency with system-level modeling tools such as VBA, Fortran, MATLAB/Simulink, or equivalent.

Demonstrated experience in steady-state system analysis, performance prediction, and trade studies.

Experience with aircraft ECS, thermal management systems, air cycle systems, or vapor cycle systems.

Familiarity with aircraft-level requirements, safety analyses, and system integration.

Proven ability to lead cross-functional technical efforts and drive analytical strategy.

Strong communication skills for conveying complex technical information to diverse audiences.
