Mechanical Engineer

About Lumafield: Lumafield was founded in 2019 to upgrade manufacturing. We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it. Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively. We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We’re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again. Lumafield is headquartered in Cambridge, MA, and has an office in San Francisco, CA. About the role: The Hardware Group is looking for a Mechanical Engineer to help design, prototype, and refine the next generation of our industrial CT scanning systems. You’ll work across disciplines - from motion systems and structures to system integration and user-facing features - to develop reliable, manufacturable, and innovative solutions. Our 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. This is a hands-on, in-person role based in our Cambridge, MA office. We are unable to sponsor or take over sponsorship of employment visas at this time. All applicants must be legally authorized to work in the United States without current or future sponsorship. Lumafield offers both competitive cash and equity compensation, as well as a health & wellness stipend, 401k, parental leave, flexible PTO, commuter benefits, company wide events and more! Lumafield is committed to building a team that represents a variety of backgrounds, perspectives, and skills, because the more inclusive we are, the better our work will be. Do you feel like your skills don’t meet every single requirement listed? We encourage you to apply anyway – If you’re excited about our technology, the opportunity, and are eager to learn more we’d love to hear from you! In keeping with our beliefs and goals, no employee or applicant will face discrimination or harassment based on: race, color, ancestry, national origin, religion, age, gender, marital domestic partner status, sexual orientation, gender identity, disability, genetic information or veteran status. Reach out if you want to be a part of what we are building. What you’ll do: Lead the technical aspects of mechanical design for complex assemblies and subsystems, developing well-scoped milestones to deliver on quarter-scale goals. Accelerate project timelines by leveraging your technical expertise to make informed tradeoffs in scope and execution. Decompose business goals into technical solutions that can be executed by multiple individuals on the team. Drive cross-functional collaboration with stakeholders to identify technical needs and develop effective engineering goals. Unblock yourself and the team by proactively assessing and eliminating the root causes of barriers. Actively work with and mentor more junior colleagues to help them refine their craft. About you: Can identify appropriate solutions to ambiguous, under-defined, and open-ended problems. Excel at navigating ambiguity and remaining resilient through the ups and downs of a project. Effectively communicate and coordinate requirements with other teams, tailoring your message to the audience. Consider the short- and long-term impacts of large technology choices. Serve as a role model for other engineers and model a standard of excellence. Have self-awareness of your strengths and weaknesses and reliably take action on feedback. Typically 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. Bonus points for: Experience leading projects through a complete product life-cycle. Experience designing motion systems, precision mechanisms, or mounting for imaging systems. Background in industrial automation, inspection, or scientific instrumentation. Familiarity with tolerance analysis, FEA, or thermal simulations. A portfolio of mechanical designs, prototypes, or shipped products you can share.
