• Demonstrate ownership and accountability throughout the product lifecycle.
• Develop holistic hardware solutions for evolving and ambiguous requirements.
• Lead supplier selection and manufacturing process decisions through vendor engagement.

Essential Skills

• Bachelor’s degree in Mechanical Engineering.
• Proficiency in CAD tools such as SolidWorks, with experience in part design and complex assemblies.
• Hands-on experience building prototypes and proof-of-concept models.
• Strong understanding of mechanical engineering principles and their application to product design.
• Excellent communication and technical writing skills.
• Experience managing full product development lifecycles and meeting project milestones.
• Ability to evaluate trade-offs in design, performance, and logistics.
• Demonstrated ability to work independently, take initiative, and drive results in a fast-paced environment.

Additional Skills & Qualifications

• Master’s degree in Mechanical Engineering.
• Experience with FEA tools such as SolidWorks Simulation or ANSYS.
• Background in designing and sustaining complex mechanical systems.
• Familiarity with ANSI Y-14.5 standards for documentation.
• Experience with tooled components (e.g., injection molding, casting, stamping).
• Knowledge of electronics packaging and sensor integration.
• Experience in automation or robotic system design.
• Proven track record of improving existing product performance.
• Proficiency with PLM systems and engineering change orders (ECOs).
• Strong organizational and team collaboration skills.
• Enthusiasm for working in a fast‑paced, agile development environment.

Work Environment

This role is based in a hands‑on lab environment rather than a traditional quiet office setting. Candidates should be comfortable working in a space with moderate background noise and active equipment in use.
