You’ll work across disciplines - from motion systems and structures to system integration and user-facing features - to develop reliable, manufacturable, and innovative solutions.\nOur product is a complex hardware-software system. Success in this role requires systems thinking, hands-on prototyping, and the ability to bring structure to ambiguous design problems. You’ll collaborate with electrical, firmware, systems, and software engineers to create hardware that’s not just functional, but delightful to use.\nThis is a hands-on, in-person role based in our Cambridge, MA office.\nWhat you'll do:\nLead the technical aspects of mechanical design for complex assemblies and subsystems, developing well-scoped milestones to deliver on quarter-scale goals.\nFollow your inventions through the full product lifecycle, from concept and design to first engineering builds and transfer to mass manufacturing.\nAccelerate project timelines by leveraging your technical expertise to make informed tradeoffs in scope and execution.\nDecompose business goals into technical solutions that can be executed by multiple individuals on the team.\nDrive cross-functional collaboration with stakeholders to identify technical needs and develop effective engineering goals.\nActively work with and mentor more junior colleagues to help them refine their craft.\nAbout you:\nCan identify appropriate solutions to ambiguous, under-defined, and open-ended problems.\nExcel at navigating ambiguity and remaining resilient through the ups and downs of a project.\nEffectively communicate and coordinate requirements with other teams, tailoring your message to the audience.\nConsider the short- and long-term impacts of large technology choices.\nServe as a role model for other engineers, and model a standard of excellence.\nHave an enthusiasm for utilizing AI tools to their fullest to improve quality and increase speed.\nTypically have a bachelor's or master's degree and multiple years of relevant experience executing a broad range of activities directly applicable to the role.\nBonus points:\nExperience leading projects through a complete product lifecycle, including through early manufacturing and into mass production.\nExperience designing motion systems, precision mechanisms, or mounting for imaging systems.\nBackground in industrial automation, inspection, or scientific instrumentation.\nA portfolio of mechanical designs, prototypes, or shipped products you can share.","description_format":"text","description_chars":2625,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial
