Engineering Intern, Process

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 process team you’ll contribute to core technology of our current and future 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. 


Lumafield's product is a complex hardware-software system. The Process Team does R&D in and between multiple disciplines. Systems-thinking and the ability to evaluate a problem and the possible solutions from multiple perspectives are essential. Join us!


What you'll do:
  • Work on the core technology enabling Lumafield to deliver its novel CT scanners
  • Design and conduct experiments and simulations
  • Analyze test data to characterize performance and troubleshoot bottlenecks
  • Create working prototypes for new hardware and software features
  • Convert scientific understanding into shipping features for customers
  • Work closely with your mentor on Lumafield’s process team
  • Work out of our Cambridge, MA office


About you:
  • Currently studying for an engineering or physics degree
  • Experience with Python and/or MATLAB
  • Are a well-rounded technical thinker
  • Exhibit insatiable curiosity for how things work
  • Have a passion for puzzles, able to troubleshoot and get to the bottom of complex issues in hardware, software and sometimes a stubborn mix of both
  • Enjoy collaborating within and across teams
  • Quickly learn and apply information in a new field of study
  • Loves building cool things that make a difference for engineering teams
  • Motivated by moving fast, shipping, and getting feedback


Bonus points for:
  • Postgraduate 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!
