What we do

We are the first publicly-traded biotech or pharmaceutical company to take the form of a public benefit corporation. Our public benefit purpose is to provide a brighter future for patients through the development of novel pharmaceutical therapies; and technologies that expand the availability of transplantable organs.

United Therapeutics (Nasdaq:

UTHR) seeks to travel down the corridors of indifference to develop treatments for rare, deadly diseases. We were founded in 1996 by a family seeking a cure for their daughter’s pulmonary arterial hypertension (PAH). Today, we have six FDA-approved therapies that treat PAH, pulmonary hypertension associated with interstitial lung disease (PH-ILD) and neuroblastoma, a rare pediatric cancer. Our near-term pipeline seeks to develop additional therapies for PAH and pulmonary fibrosis (PF).

The cure for end-stage life-threatening diseases like PAH, PH-ILD, PF, and many others is an organ transplant, but only a small percentage of donated organs are available to address the vast need. For this reason, we are working to create manufactured organs to address the shortage of kidneys, hearts, lungs, and livers available for transplant. We believe an unlimited supply of tolerable, transplantable organs will eliminate the transplant waiting list and cure end-stage organ diseases for which transplant is not currently an option.

United Therapeutics does not provide relocation assistance, housing, or transportation. The selected Co-op will need to be onsite at the Manchester, NH office for the entire duration of this co-op role, from July 2026 to December 2026.

This isn’t a “grab coffee and observe” kind of co‑op. Over six months, you’ll jump straight into hands‑on, high‑impact work with scientists who are pushing the boundaries of what’s possible in organ manufacturing. You’ll help design, print, test, and improve 3D‑printed lung scaffolds—technology aimed at solving one of medicine’s biggest challenges: the organ transplant shortage. Along the way, you’ll turn classroom theory into real-world results, own a meaningful project, and build skills in cutting‑edge bioengineering that actually make a difference.

If you’re curious, driven, and excited by work that feels big, this is the kind of experience you’ll carry with you long after the co‑op ends.

Assist a project lead/scientist in one of the following areas:
1) Materials application development, including ink formulations and printing and post-processing efforts.
2) Cellularization methods of 3D printed scaffolds to generate physiologically and biologically relevant tissue engineered lung constructs. Co-ops are educational positions requiring basic knowledge and understanding of material science fundamentals, 3D printing processes, tissue engineering, and manufacturing to support research and development in production of 3D-printed lung scaffolds suitable for recellularization.

This co-op will include a project/deliverable that will be completed during employment and will utilize academic foundations to further career aspirations.

• Develop, evaluate and/or improve methods for 3D printing lung scaffolds using hydrogels
• Design and conduct print process experiments for lung scaffold printing to achieve consistent, high fidelity 3D printed lung scaffolds
• Assess mechanical and material properties of 3D printed constructs
• Validate 3D printer hardware & software and communicate findings
• Communicate and collaborate across functions within the organ manufacturing group
• Perform additional duties as assigned

Minimum Qualifications

• Candidates must be at least a rising undergraduate junior and actively enrolled student in an academic program for the duration of the assignment; pursuing BA/BS, MS, PhD in Biomedical, Mechanical, Chemical Engineering, Material Science or related discipline.
• Experience with 3D bioprinting (DLP/SLA)
• Experience working in a hands-on laboratory environment with ability to work independently and as part of a team
• Strong attention to detail, knowledge of good lab practices (GLP), and experience following experimental methods and…
