Senior Mechanical Engineer - Coffee

Senior Mechanical Engineer - Coffee – Needham, MA (On-Site)

Build the Products Millions of People Use Every Day

At SharkNinja, we don't just design appliances — we rethink what they can do. Our Ninja brand sits in tens of millions of homes worldwide, and the reason our products earn 5-star reviews comes down to the engineering underneath them. We're looking for a Senior Mechanical Engineer to help shape what comes next.

This is a front-end role. That means you're not inheriting someone else's design brief — you're the one figuring out what's possible before the brief exists. You'll work at the edge of what's technically feasible, turning ambiguous consumer problems into working prototypes, and working prototypes into product roadmap decisions.

What You'll Own

You'll be embedded in the early-stage innovation phase — the space between "what if?" and "here's proof it works." Your job is to move fast, validate ideas early, and hand off credible, consumer-tested solutions to the development team.

In practice, that looks like:

• Driving the front-end technology and feasibility roadmap for products, collaborating with engineering, industrial design, brand, and test kitchen teams across the US, UK, and China
• Building proof-of-concept rigs and functional prototypes to stress-test ideas early — before the business invests in full development
• Working across the full system: mechanical design, sensors, software, batteries, connectivity — you see the whole picture, not just your slice of it
• Communicating ideas rapidly through sketching, CAD layouts, 3D models, and physical prototypes
• Running design and engineering studies — solo and in teams — with the consumer experience as the north star at every stage
• Mentoring junior engineers and contributing to a team culture that treats failure as signal, not setback
• Staying close to IP development, identifying novel and inventive solutions alongside R&D

What You Bring

You're a hands-on engineer who's most energized when the problem is undefined. You have strong mechanical fundamentals, an instinct for electromechanical systems, and enough breadth to hold a real conversation with software and electrical teams. You prototype to learn, not just to present.

Required:

• BS in Mechanical Engineering, Product Design, or a closely related field
• 4–8+ years of experience in mechanical engineering or product design
• Hands-on experience designing electromechanical products in a product development environment
• Proficiency in SolidWorks or Creo
• Experience with plastic part design, including injection-molded, silicone, and rubber components
• Comfortable in the lab: building prototypes, running tests, reporting findings, and determining next steps
• Strong communicator — you can sketch an idea on a whiteboard and defend it in an engineering review

Nice to Have (But Not Required):

• Background in consumer goods or household appliances
• Experience designing sheet metal components
• Familiarity working with IP teams to identify novel or inventive solutions

Why This Role, Why Now

SharkNinja is growing fast and investing heavily in its front-end R&D capability. This is a moment to join an innovation team that has real influence over what gets built — not just how. You'll have the freedom to experiment, the resources to prototype at speed, and a global cross-functional team that takes the engineering seriously.

If you want to do the most interesting work of your career on products that actually reach people's lives, we'd like to meet you.
