Principal Systems Engineer

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
