Engineering Intern, Mechanical

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:


As an intern on our hardware team you’ll contribute to our Neptune and Triton CT scanners. You’ll have a mentor for the summer who will show you the ropes and help you learn, contribute and grow. You’ll also have plenty of time in our Boston office to meet and network with team members across Lumafield to learn about the ins and outs of a hypergrowth hardtech startup. Join us!


What you'll do:
  • Work on the mechanical subsystems of our scanning systems (e.g., Neptune and Triton) and core technology platforms
  • Work closely with your mentor on Lumafield’s hardware team
  • Work out of our Cambridge, MA office


About you:
  • Currently studying for a mechanical engineering or related degree
  • Experience with CAD software
  • Loves building cool things that make a difference for engineering teams
  • Motivated by moving fast, shipping, and getting feedback


Bonus points for:
  • OnShape experience
  • Rapid prototyping experience
  • Prior startup experience
  • A strong portfolio, blog, github, or profile we can review


$28 - $33 an hour

This role will be performed alongside a cohort of Lumafield summer interns and is a paid position. We also offer relocation assistance if you are out-of-state. We do not currently offer visa sponsorship or OPT eligibility.


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.
