Helix Carbon
Helix Carbon produces electrolyzers with dramatically improved system lifetimes to convert point-source carbon dioxide into useful chemicals. Its novel catalyst coating techniques enable stability in mixed gas streams and conversion even at low CO₂ concentrations, eliminating the need for separate carbon capture in many applications. Coupled with our ability to adjust the ratio of carbon monoxide and hydrogen produced, Helix Carbon provides drop-in, carbon-neutral reducing gases to decarbonize the iron industry.

LymeAlert
LymeAlert is the first at-home tick testing kit for Lyme disease and other tick-borne diseases. The kit is paired with a computer vision-enabled app that measures test results and collects GIS data. Our goal is to map disease hot spots and use ML to predict where diseases are spreading next. Our vision is to speed up time to diagnosis, build awareness and the ability to prevent disease, and aid in global disease surveillance as tick diseases are a major global threat.
Internship – flexible between in person, hybrid, or remote
Company HQ – Cambridge
Required / Desired Skills
We have a few opportunities for interns.
Please select the role you are most interested in on the application form.
- We have research going on in the lab that we could support an intern to participate in. (LymeAlert Research)
- We are working with building out the app and data collection side of our technology and are collaborating with non-profits and public health agencies on this project. A CS background with interest in public health would be a great fit on that side. (LymeAlert CS)
- We have an opportunity for a marketing/social media/business development intern whose role would be in assisting with creating a public health campaign and awareness building for Lyme and other tick-borne diseases in addition to helping create sales and marketing strategies. (LymeAlert BizDev)
Company Culture
We have a team standup Monday morning and talk about planned meetings and goals for the upcoming week, both individually and as a team. Our intern will have a point person that they will primarily work with during the week. On Friday, we have a “check out” meeting and talk about which goals we met and which we might need to continue working on further. We’ve also kept the delta v tradition of “Booms, Busts, and Be Thankfuls” as part of our team culture! We have had an intern before and our goal was to allow them to learn as much as they could from what we are doing, but also for us to learn from the intern. We want to give our intern agency to contribute to what we are building in a meaningful way and are open to longer term collaborations for a great fit!
