Who We Are

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.

Who You Are

As an Associate/Research Scientist, Analytical Chemistry, you’ll be a critical scientific partner at the intersection of discovery, development, and scale‑up—helping transform complex chemistry into therapies that can change lives. In this role, you’ll work side‑by‑side with synthetic chemists to develop and execute advanced analytical methods, generate high‑quality data, and solve real‑world challenges tied to route selection, impurity control, and process understanding. You’ll bring clarity to complexity by interpreting chromatographic data, supporting tech transfer and GMP readiness, and ensuring analytical rigor from early research through manufacturing. If you enjoy being hands‑on in the lab, thinking deeply about data, and collaborating across teams to move innovative science forward, you’ll find both purpose and momentum hereThe Associate/Research Scientist, Analytical Chemistry supports a team of synthetic chemists by developing and executing various analytical (LC, GC, SFC, KF etc.) methods to solve complex research problems such as route scouting, process understanding, scale-up and impurity isolation/purification. This role also partners with QC, and external vendors to develop robust analytical methods, generate high-quality data, to ensure analytical readiness for scale-up, tech transfer and GMP manufacturing.

• Collaborate with synthetic chemists to support isolation and characterization of API, impurities, intermediates, and markers using preparative techniques such as prep‑HPLC and SFC while meeting assigned project timelines
• Execute established analytical methods for chromatographic techniques including LC, GC, and SFC using appropriate detection such as UV, ELSD, CAD, MS, and FID
• Trend and interpret chromatography data to provide actionable insights including reaction completion, chiral selectivity, impurity profiles, and purge trends, and communicate results clearly to synthetic chemists
• Analyze samples or materials from vendors according to established or transferred analytical procedures
• Operate, calibrate, and maintain laboratory instruments and associated computer systems by coordinating with groups such as IT and OT for basic troubleshooting
• Coordinate vendor service activities including preventive maintenance, repairs, and column selection, and assist with obtaining quotes or making purchases for columns, consumables, and chemicals
• Author and review technical documentation such as analytical reports, method SOPs, method development summaries, investigations, and data packages for method transfer
• Contribute to technical documentation such as development summaries, experiment records, method notes, and invention disclosures as needed
• Ensure data quality and adherence to internal policies and scientific standards
• Review data packages such as method development reports and protocols from other departments and vendors
• Utilize scientific literature to support execution of research assignment objectives
• Drive improvements in analytical throughput and lab efficiency
• Support safety practices, chemical hygiene, and waste management while applying principles of sustainability

• Proficient with MS Office, ChemDraw, and SciFinder

Minimum Requirements

Research Scientist, Analytical Chemistry R&D

• 8+ years of relevant chemistry experience in pharmaceutical industry with a Bachelor's degree or 6+ years of relevant chemistry experience in pharmaceutical industry with a Master's degree or 2+ years of relevant chemistry experience in pharmaceutical industry with a PhD
• Experience in independently leading analytical investigations, hands-on experience with HPLC/UPLC/GC method development, troubleshooting and common sample prep techniques
• Working knowledge of LC–MS (TOF) for mass-based compound characterization
• Ability to interpret analytical data in the context of chemical process development
• Sound knowledge of chromatography software: Waters Empower, Agilent MassHunter, Thermo Scientific Chromeleon and Waters ChromScope
• Clear technical writing and data storytelling (chromatogram stacking, overlays, etc.)
• Comfortable in fast-paced R&D environments with shifting priorities
• Experience with chiral analysis/method development (chiral HPLC and/or SFC) is highly preferred

Preferred Qualifications

• Doctor of Philosophy (PhD) in chemistry or related discipline
• Sound knowledge of MS Office, ChemDraw, and SciFinder
