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 San Francisco, CA. and has an office in Cambridge, MA.
About the role:
The Hardware Group is looking for a Staff Mechanical Engineer to set technical direction for the mechanical engineering domain within our Hardware Group. You'll shape the architectures behind our motion systems, structures, and integrated CT hardware, along with the engineering practices used to develop them. You'll connect product needs to a technical roadmap for the next one to two years.
This is a hands-on individual contributor role with impact across multiple teams. You'll partner with electrical, firmware, systems, software, manufacturing, and product colleagues to resolve difficult mechanical and integration challenges. Your work will improve both the systems we ship and other engineers' ability to make sound decisions and deliver reliably.
This is a hands-on, in-person role based in our Cambridge, MA office.
What you'll do:
- Define and lead the mechanical domain's technical roadmap with engineering and product leaders. Identify investments that address customer needs and expand what our systems can do.
- Lead strategic initiatives spanning multiple teams, from concept through validation and production. Turn ambiguous goals into aligned requirements and milestones, and manage technical risks, interfaces, and dependencies.
- Develop mechanical architectures and reusable subsystems that multiple teams can build on. Make clear tradeoffs among performance, cost, reliability, safety, and manufacturability.
- Stay close to the hardware. Use analysis, prototypes, and experiments to resolve the domain's hardest technical problems, reduce uncertainty early, and unblock teams.
- Identify new technical and product opportunities, then establish feasibility through focused development work. Guide adoption of the resulting platforms, tools, or components across teams.
- Establish shared practices for mechanical design, technical reviews, validation, and documentation. Partner with manufacturing to turn lessons from builds and production into repeatable improvements.
- Build alignment across disciplines when requirements or technical approaches conflict. Document decisions and their rationale so teams and leaders can act with a shared understanding.
- Mentor Senior engineers in architectural judgment and technical leadership. Help engineers across teams solve problems independently and contribute to shared standards.
About you:
- You've set technical direction for a mechanical domain or platform and led its adoption across multiple teams, with results that extend beyond your own designs.
- You have deep mechanical design judgment, strong engineering fundamentals, and practical experience with analysis, prototyping, testing, and system integration.
- You've delivered complex hardware through engineering builds and into production, taking responsibility for technical risks and dependencies across teams.
- You connect business and customer needs to a practical technical roadmap. You can make progress with incomplete information and revise your approach as evidence develops.
- You communicate technical tradeoffs clearly, build consensus across disciplines, and serve as a trusted technical partner to engineering and product leaders.
- You've helped experienced engineers grow and created tools, design guidance, or standards that other teams use successfully.
- You're interested in using AI tools to improve engineering quality and speed, and you apply engineering judgment to verify their results.
- You bring a degree in mechanical engineering or a related field, or equivalent practical experience.
