SharkNinja is seeking a Senior R&D Mechanical Engineer to join the Ninja Coffee R&D Engineering team and lead the development, optimization, and validation of product system performance . This role focuses on understanding how complex electromechanical systems function , identifying performance drivers, and applying root cause and corrective action (RCCA) methodologies to improve product capability.

The R&D team owns the core performance of our products , from front-end technology exploration through product development and mass production . This engineer will lead technical investigations, build prototypes, design experiments, analyze performance data, and collaborate cross-functionally to deliver best-in-class product performance.

This is a hands-on engineering role focused on system-level performance engineering , experimental testing, and problem solving in the lab. While not primarily CAD-focused, the role influences product architecture through design reviews, data-driven insights, and system-level engineering expertise .

• Lead system-level performance development for electromechanical consumer products, focusing on thermal, fluid, and mechanical systems
• Identify key performance drivers and engineering tradeoffs to optimize product functionality, efficiency, and reliability
• Translate performance targets into test plans, engineering models, and validation strategies

• Drive root cause analysis (RCA/RCCA) for performance issues using structured problem-solving methods
• Investigate system behavior through data analysis, failure analysis, and hypothesis-driven experimentation
• Implement corrective actions and design improvements based on engineering findings

• Design and execute engineering test plans, DOE experiments, and performance characterization
• Build and modify functional prototypes and test rigs to validate theories and system behavior
• Analyze experimental data using Excel, statistical tools, and engineering models
• Develop engineering insights and performance models that inform product architecture

• Partner with mechanical, electrical, firmware, and product teams to integrate technologies into new products
• Participate in design reviews and architecture discussions to ensure performance requirements are achieved
• Serve as the technical authority on system performance and engineering fundamentals

• Lead technical performance workstreams across multiple projects
• Mentor junior engineers and co-op students
• Communicate engineering insights to both technical and non-technical stakeholders

• Strong ability to break down complex engineering problems into first principles
• Expertise in system-level troubleshooting and root cause analysis
• Hands-on engineer comfortable prototyping, building test setups, and working in a lab environment
• Strong intuition for physics and engineering fundamentals
• Ability to translate experimental results into engineering insight and product improvements
• Comfortable working in fast-paced, iterative product development environments
• Clear communicator capable of explaining complex technical concepts

Strong background in one or more of the following areas:

• Thermodynamics and heat
