(Pronounced mouse, not moose.) People deserve tech and lifestyle products that are fit for purpose, perform as promised, and empower them to be their best. That’s why we’re building the go-to brand for products that genuinely deliver. \nFor over 10 years, we’ve pushed product performance to its limits, designing from first principles, validating through real-world testing, and investing millions in R&D. In parallel, we’ve built world-class in-house marketing capabilities, creating highly engaging, performance-led content that proves what our products can do and resonates with a passionate, fast-growing community around the brand. \nFrom throwing phones off dams to launching category-defining products, our ambition is simple: raise the standard of the industry and build one of the most effective consumer brands in the world. \nAbout the Role\nWe’re excited to welcome a Mechanical Process Engineer (CSP - Cases & Screen Protectors) to our growing China-based engineering team. \nThis role is central to the design and development of Mous phone cases, with a strong focus on structural performance, reliability, and manufacturability.\nAs an MPE (CSP), you will join the development of high-performance mechanical structures from concept through mass production. You’ll work closely with cross-functional teams and external manufacturing partners to ensure products meet rigorous validation requirements, scale efficiently, and remain industry-leading. \nThis is a hands-on, technically demanding role suited to someone who enjoys solving complex engineering challenges in a fast-paced environment. \nThis position is fully on-site at our Dongguan office, Monday to Friday, 9:00am-6:30pm. \nAbout You\nAs an MPE at Mous, you’ll collaborate closely with the New Product Development, Engineering, Quality, and Production teams, reporting directly to Colin, our Lead MPE. \nYou are proactive, detail-oriented, and comfortable owning technical challenges end to end. You thrive in an execution-focused and fast-paced environment and play a key role in driving projects to completion with precision, speed, and quality. \nKey Responsibilities:\n1. NPI Strategy & Design Optimisation\nCollaborate with the New Product Development (NPD) team and participate in DFMA (Design for Manufacturing and Assembly) reviews, learning how to optimize product designs for durability, manufacturability, cost, and high-volume production.\n\nApply basic knowledge of materials, mechanical processes, tooling, and CMF (Color, Material, Finish) to support the development of feasible engineering solutions aligned with product requirements.\n\nProvide technical assistance during the transition from design to execution, helping to balance aesthetic intent with manufacturing reality.\n\n2. Technical Vendor & Project Governance\nSupport the management and audit of OEM/ODM and manufacturing suppliers, helping ensure their technical activities and process controls align with the product development roadmap under the guidance of senior team members.\n\nAssist in guiding product development from conception to execution; help track timelines and milestones to support timely and complete delivery of products and engineering modifications.\n\nContribute to establishing acceptance criteria for manufacturing processes and materials based on industry best practices, helping ensure supplier output meets internal standards.\n\n3. Validation, Testing & Tooling\nParticipate in developing comprehensive testing plans that simulate critical requirements and real-world usage scenarios to validate product performance and mechanical integrity.\n\nAssist in designing and evaluating precision testing jigs and fixtures, helping to ensure validation processes are accurate, repeatable, and suitable for mass production environments.\n\n4. Problem Solving & Continuous Improvement\nParticipate in Root Cause Analysis (RCA) on test failures and technical challenges; help implement corrective actions to resolve reliability issues related to materials, tooling, or processes.\n\nLearn to identify potential manufacturing risks and technical bottlenecks early in the lifecycle; support the escalation of issues and assist in providing strategic solutions to ensure prompt resolution.\n\nContribute to ongoing product enhancements by helping analyze Customer Experience (CX) and Field Return (FR) data, supporting a culture of quality advancement and continuous improvement.\n\n5. Cost Engineering & Value Realisation\nAssist in performing detailed cost analysis for new and existing projects.\n\nHelp identify and implement cost-saving opportunities through material, tooling, or process optimisation while maintaining product integrity, under the guidance of senior engineers.\n\nHow will success be measured?\nYear-on-year reduction in average PI ratio \n\nNet 180-day product PI ratio below 2.5% \n\nEffective KPI implementation for lead time in resolving critical issues \n\nDemonstrated year-on-year continuous improvement \n\nSkills requirements:\nSome experience in phone case design and development or similar consumer electronic products.\n\nBasic understanding of product design, tooling technologies, materials, and manufacturing processes for phone cases (e.g., over-moulding and co-moulding).\n\nFamiliarity with engineering plastics such as PC, TPU, TPE, ABS, and PA66. Exposure to metals (stamping or die-casting) is a plus.\n\nSome knowledge of post-processing techniques including silk screen, UV coating, PU coating, and assembly.\n\nGeneral understanding of DFX related to feasibility, quality, post-processing, and cost evaluation.\n\nFamiliarity with testing standards, validation execution, jig design, and failure analysis.\n\nSome experience in verifying assembly jigs and manufacturing processes.\n\nBasic knowledge of quality control tools such as FAI, SPC, and CPK, including data collection and analysis during mass production.\n\nSome troubleshooting experience and ability to communicate effectively with technicians and suppliers.\n\nWorking knowledge of SolidWorks for mechanical design and simulation (basic proficiency is acceptable).\n\nSoft skills:\nEnergetic, proactive, and eager to learn.\n\nOpen-minded and strong in communication.\n\nCollaborative, adaptable, and comfortable working on technical issues.\n\nFluent in English.\n\nNice-to-have: \nPMP certification \n\nExperience driving continuous product improvement \n\nUnderstanding of APQP (Advanced Product Quality Planning) \n\nAbout Our Offer\nWe work fully on-site in our custom Dongguan office so that we can retain the collaborative and vibrant Mous culture that people love.\nWhy work at Mous? \nLong-Term Rewards: One month of paid leave after 5 years’ service. \n\nCompetitive Pay: A strong starting salary aligned with your experience and impact. \n\nDynamic Culture: A collaborative, high-performance, data-driven environment where innovation thrives. \n\nGrowth & Development: Opportunities to learn, stretch, and grow through new challenges. \n\nProfessional Development: Training budget plus regular Mousterclasses to share expertise across teams. \n\nCharlie HR Perks: Access to exclusive perks and discounts via Charlie HR. \n\nGlobal Collaboration: Seamless remote collaboration with international teams, including weekly all-hands and virtual socials. \n\nAbout Our Values\nGet Results - We take accountability, prioritise impact, and push standards higher. \nWork Together - We collaborate openly, challenge constructively, and learn from each other. \nEnjoy the Ride - We stay agile, embrace change, and enjoy building something special together.\nAbout Our Commitment\nMous is an equal opportunity employer.
