Job Title: Mechanical EngineerJob Description The Mechanical Engineer supports mechanical design and integration activities for assigned assemblies and interfaces, working from system-level and component-level requirements. This role focuses on developing and maintaining high-quality CAD models and engineering drawings, executing engineering changes through established configuration control processes, and resolving build, test, and production issues using structured root cause and corrective action methods.
Responsibilities Support mechanical design and integration tasks for assigned assemblies and interfaces based on system-level and component-level requirements.
Create and revise 3D CAD models and detailed 2D engineering drawings, ensuring documentation quality and adherence to applicable standards.
Apply Geometric Dimensioning and Tolerancing (GD&T) practices to mechanical drawings in accordance with relevant standards.
Develop and maintain released documentation, including models, drawings, and associated engineering records.
Execute engineering changes through configuration control processes, including engineering change orders (ECOs) and configuration management procedures.
Participate in and support configuration control boards (CCB) or similar configuration management activities to ensure design integrity.
Provide sustaining engineering support for released hardware, including design updates, improvements, and issue resolution.
Investigate and resolve build, test, and production issues using structured root cause analysis and corrective action methodologies.
Collaborate with cross-functional teams to ensure mechanical designs meet performance, manufacturability, and quality requirements.
Document analyses, design dispositions, and engineering changes clearly and accurately for technical and non-technical stakeholders.
Essential Skills Minimum of 5 years of mechanical design experience in an industrial, automotive, aerospace, or defense environment.
Proficiency with 3D CAD tools, with strong preference for Creo, including creation and modification of complex models.
Experience in creating and maintaining detailed 2D engineering drawings and released documentation.
5, with demonstrated ability to interpret and apply GD&T on mechanical drawings.
Ability to execute engineering changes through formal configuration control processes.
Experience supporting mechanical design and platform integration activities, as well as sustaining engineering for released hardware.
Strong written communication skills, with the ability to clearly document analyses, dispositions, and engineering changes.
Strong verbal communication skills, enabling effective collaboration with engineering and production teams.
Ability to perform structured root cause analysis and implement corrective actions to resolve build, test, and production issues.
Additional Skills & Qualifications Mechanical design experience in environments such as industrial manufacturing, automotive systems, aerospace platforms, or defense products.
Familiarity with configuration management practices, including participation in configuration control boards (CCBs) and processing engineering change orders (ECOs).
Experience providing sustaining engineering support for existing mechanical hardware throughout its lifecycle.
Comfort working from system-level and component-level requirements to develop robust mechanical solutions.
Ability to balance design quality, manufacturability, and schedule in a fast-paced engineering environment.
Work Environment This role follows a 9/80 work schedule, providing a compressed workweek with every other Friday typically available as a non-working day, subject to team and project needs. The position operates in a hybrid setting, with three days per week on-site, typically Tuesday through Thursday, and remote work on other days as appropriate. The work environment combines office-based design activities with close collaboration with engineering, manufacturing, and test teams, using modern 3D CAD tools such as Creo and standard engineering documentation systems. The culture emphasizes clear communication, structured engineering processes, and a focus on quality, reliability, and continuous improvement in mechanical design and integration.
