Job Description

Intergalactic, now part of Unison, a GE Aerospace Company, is a team of engineers, technologists, designers, mathematicians, and problem solvers committed to a singular idea: reviving the no-boundaries mentality in aerospace.

We are a team of the nation’s best, regardless of where we live.

The Lead Engineer 1 - Thermal Dynamics provides analytical modeling capabilities to the systems engineering team by leading component and system level trade studies and working with the systems engineers to develop a system architecture to meet customer requirements.

In cooperation with the Program Management team, the Lead Engineer 1 - Thermal Dynamics leads and executes thermal modeling and analysis efforts.

This role is responsible for performance requirements compliance assessment, interpreting and analyzing test data, synthesizing test data and correlating system models, and building up and maintaining system models and model libraries.

During the program, the Lead Engineer 1 - Thermal Dynamics will work with a multi-disciplinary project team of subject matter experts in fields such as thermal/aerospace analysis, installation, mechanical design and analysis, reliability, controls, electronics and software, and testing.

Roles and Responsibilities

• Assisting the System Engineer with developing the program’s system architecture and technical approach. This can include thermal and controls analysis and testing and test analysis as it relates to system model correlation and performance requirements compliance assessment during development and verification and validation.
• Identify and manage program’s technical risks as it pertains to thermal performance.
• Serve as technical lead for modeling and analysis, provide clear objectives that are measurable and attainable, and coordinate modeling and analysis activities with other engineering functional groups.
• Work closely with the Systems Engineer and Program Manager to ensure successful execution of modeling, analysis, and testing development for programs.
• Manage thermal and performance technical requirements and assist the program Systems Engineer in their requirements traceability, decomposition, derivation, and verification & validation.
• Allocate and decompose high-level requirements into lower-level specifications to internal functional groups, components, and suppliers as applicable for thermal and performance requirements.
• Researching and recommending investments or changes in technology, methodology, toolsets, procedures, equipment, systems, etc. to continually improve the discipline health and the Intergalactic’s products and services.
• Communicate and collaborate with customers and suppliers as part of design development process.
• Review and approve documentation for transition from prototype to production.
• Provide engineering support to trouble shoot and diagnose non-performing products (RCCA, lessons learned, etc.).
• Perform other duties as assigned.

Required Qualifications

• Bachelor’s degree from an accredited university or college and 8-10 years of relevant experience.
• Relevant advanced degrees, including an MS or PhD, will be considered as satisfying a portion of the industry experience requirement.
