Harris is seeking a Senior Member, Mechanical Engineering Staff (SMES) to support the design, layout, testing, and evaluation of electro-mechanical and mechanical devices and systems. This role is responsible for preparing design specifications, analyses, and recommendations for presentation and approval, while contributing to product development activities across assigned projects.

The successful candidate will analyze mechanical requirements to determine the feasibility of designs within time and cost constraints, investigate solutions to product or process issues, and consolidate results of mechanical design elements for assigned efforts. This position also supports the origination or modification of material, component, and process specifications or requirements, and contributes to interpretation and implementation of customer specifications and documentation requirements.

This is a professional role equivalent to a Level 4 for an experienced engineer with strong knowledge of the mechanical engineering job area and broad knowledge of project management. The role works under general oversight and may be responsible for large projects or processes both inside and outside of immediate job area.

• Prepare design specifications, engineering analyses, technical recommendations, drawings, and supporting documentation; interpret and implement customer requirements.
• Assess design feasibility, select materials, develop trade studies, and evaluate manufacturing and producibility considerations.
• Perform finite element analysis (FEA) using tools such as Ansys to assess structural, thermal, and vibration performance.
• Develop engineering prototypes using rapid fabrication methods, including 3D printing and laser cutting.
• Support product data management using PLM tools, including Windchill, and maintain configuration control of released baselines and engineering changes.
• Provide hands‑on factory build support, including troubleshooting and disposition of technical issues.
• Support environmental ruggedization and testing for shock, vibration, thermal, humidity, and other operational conditions, including MIL-STD-810 testing and documentation.
• Ensure assigned tasks meet technical, cost, and schedule objectives, support program execution using Earned Value Management (EVM) principles, and identify risks and recommend alternatives.
• Report technical status, forecast needs, and contribute to achieving program and project operational targets.
