Build the Products People Reach for Every Morning

Personal care is one of SharkNinja's fastest-growing categories — and the Shark Engineering team is at the center of it. We're looking for a Mechanical Engineer II to help design and develop the next generation of haircare products: things that work better, feel better, and genuinely improve people's daily routines.

This is a hands-on role with real creative latitude. You'll work across the full product lifecycle — from initial concept through mass production — on a team that moves fast, prototypes early, and takes consumer experience seriously at every stage.

What You'll Do

You'll be a core contributor on a cross-functional engineering team, owning design problems from first principles through manufacturable solutions.

• Define product architecture on innovative new haircare platforms, collaborating closely with electrical, ID, and product development teams
• Design parts and assemblies for injection molding, sheet metal, extrusion, machining, and other manufacturing processes
• Build and iterate prototypes for design reviews, performance testing, and consumer validation
• Integrate electrical systems into mechanical designs, evaluating trade-offs and making meaningful design decisions
• Design and execute DOEs to develop a rigorous, first-principles understanding of key performance variables
• Tear down, debug, and analyze electro-mechanical appliances to identify root causes and improvement opportunities
• Source and validate critical components with global manufacturing and vendor partners
• Research emerging technologies to help shape SharkNinja's future product roadmap

What You Bring

• BS or MS in Mechanical Engineering
• 4–8+ years of experience in product design and development, working within real cost and manufacturing constraints
• Proficiency in SolidWorks and/or Creo (Creo preferred)
• Strong knowledge of injection molding DFM, sheet metal forming, 3D printing, and laser cutting
• Experience creating engineering drawings with GD&T and tolerance stack-ups
• Solid grasp of heat transfer, thermodynamics, and fluid flow
• Sharp analytical skills and a genuine instinct for identifying problems before they become issues
• Comfortable switching gears quickly and thriving in a fast-paced environment
• Proficient in Microsoft Excel and PowerPoint

Why This Team

You'll be joining a category that's growing fast, on a team with the freedom to experiment and the resources to execute. The products you work on will reach consumers quickly — and you'll see the impact of your engineering decisions in the market, not just in a lab. If you want to do meaningful work on products people use every day, this is the role.
