Sr Advanced Systems Engineer

About the role

As a Senior Advanced System Engineer at Honeywell Aerospace, you will design, develop, and integrate complex Environmental Control Systems (ECS) for Air Transport, Regional, Business, and Military aircraft. This role involves collaborating with cross-functional teams to ensure system performance, reliability, and compliance with industry standards. You will report directly to the Systems Engineering Manager and work from the Torrance, CA location on a hybrid schedule.

Responsibilities

• Develop and refine ECS performance models and simulations for complex air and vapor cycle systems, including validation and verification of system-level steady-state requirements.
• Conduct thermodynamic, heat transfer, and fluid mechanics analyses to optimize system performance.
• Define system and equipment-level key performance parameters and generate/validate associated requirements.
• Create and maintain system-level steady-state models, including run-time performance optimization, model validation against component and system test data, and generation of model documentation.
• Coordinate system modeling/development processes and handoffs between internal and external stakeholders; communicate with chief engineering and technical management.
• Support System Integration Testing, including facility architecture and requirements, test model definition, characterization test plans/procedures, test execution support, and data processing/review and model calibration.

Requirements

You must have:

• Bachelor’s degree in Mechanical, Chemical, Engineering Physics, or Aerospace Engineering.
• 5+ years of experience in mechanical, chemical, or related engineering fields, with emphasis on thermal management system modeling and analysis.
• Strong knowledge of system design principles, integration, and testing methodologies.
• Proficiency with systems modeling tools and software such as NPSS, SysML, MATLAB, or similar platforms for mechanical thermal analysis and design.

We value:

• Advanced degrees in Mechanical Engineering, Chemical Engineering, Systems Engineering, Aerospace Engineering, or related technical fields.
• Experience in physics-based AI/ML model development.
• Experience in advanced thermal management, advanced vapor cycle systems design and development.
• Experience in mechanical engineering thermal simulations, system modeling and analysis, and system integration test.
• Familiarity with regulatory standards and compliance requirements.
• Ability to work effectively in cross-functional teams and manage multiple priorities.

Pay

The annual base salary range for this position is $140,000.00 - $176,000.00. This serves as a general guideline; actual offers consider the scope and responsibilities of the position, candidate’s work experience, education, training, key skills, and market/business considerations.

Benefits

• Employer-subsidized medical, dental, vision, and life insurance.
• Short-term and long-term disability coverage.
• 401(k) match, flexible spending accounts, and health savings accounts.
• Employee assistance program and educational assistance.
• Parental leave and 12 paid holidays.
• Paid time off for vacation, personal, and sick time.
