What You’ll Do We are seeking a highly experienced Principal Mechanical Engineer to help lead the mechanical design and development of our innovative direct-to-consumer product, which integrates hardware, software, and firmware components. In this role, you will be responsible for driving product design from concept through production, ensuring the highest standards of performance, reliability, and manufacturability. The ideal candidate will have a passion for understanding the customer and delivering outstanding user experiences, an expert grasp of mechanical systems, and experience working with consumer hardware products. Primary Responsibilities Include: Lead the mechanical design, analysis, and development of consumer hardware products, focusing on performance, durability, and aesthetics. Collaborate closely with cross-functional teams and in particular, acting as a conduit between industrial design, product management, and engineering. Drive the product development process from early-stage concept, through prototyping, testing, and production, to ensure products meet quality, cost, and schedule targets. Utilize 3D CAD software (e.g., SolidWorks, Creo) to develop mechanical models, assemblies, and detailed drawings. Perform engineering calculations and simulations to ensure mechanical integrity, thermal performance, and manufacturability. Oversee prototype development and testing, including designing test plans to validate product performance and resolve issues. Lead design reviews and work closely with suppliers and global manufacturing partners to optimize the design for mass production. Stay current with emerging technologies, materials, and manufacturing processes to inform product design and innovation. Mentor and provide technical guidance to junior engineers, helping them to develop their skills and advance their careers. What You’ll Bring:

Bachelor’s or Master’s degree in Mechanical Engineering or a related field. 8+ years of mechanical engineering experience, with at least 5 years working on consumer products. Proven experience leading the design and development of complex mechanical systems from concept to mass production. Expertise in CAD tools (SolidWorks, Creo) and familiarity with simulation tools (e.g., FEA, CFD). Strong understanding of materials science, manufacturing processes (injection molding, die casting, stamping, CNC machining), and DFM principles. Experience partnering closely with industrial designers to balance aesthetics with mechanical function and manufacturability. Experience working together with product management to understand the “why” and to be the voice of the customer. Proven ability to collaborate with cross-functional teams, manage project timelines, and deliver high-quality products on time. Experience vetting and working with global suppliers and manufacturing partners. Excellent problem-solving skills, with the ability to think critically and creatively to resolve technical challenges. Strong communication, EQ, and leadership skills, with the ability to guide and mentor junior engineers. What Values You’ll Share
