Co-op Intern

Job Title: Summer-Fall 2026 Co-op-Intern - Medicinal Chemistry, Integrated Drug Discovery

Location: Cambridge, MA 

About the Job

Are you ready to shape the future of medicine? The race is on to speed up drug discovery and development to find answers for patients and their families. Your skills could be critical in helping our teams accelerate progress. 

We are seeking an undergraduate chemistry major to execute computer-aided drug design (CADD) studies for approximately 6 months; the successful candidate will further develop data science skills as applied to chemistry, develop molecular modeling techniques and computer programming skills, learn medicinal chemistry, and gain further understanding of the drug discovery process by participating in an industrial medicinal chemistry department.

We are an innovative global healthcare company with one purpose: to chase the miracles of science to improve people’s lives. We’re also a company where you can flourish and grow your career, with countless opportunities to explore, make connections with people, and stretch the limits of what you thought was possible. Ready to get started?

Main Responsibilities

• Benchmark at the software development stage, a CADD tool aimed at assisting Medicinal Chemists in the design, optimization and profiling of small molecule targets for drug discovery programs.

• Beta test the software product as it is being developed.

• Learn to retrieve compounds along with their associated biological and DMPK data from a corporate chemicals registration database.

• Utilize internal databases and tools to understand SAR around project data

• Collaborate with other team members to design and prioritize target compounds which address project challenges.

• Continue to learn from literature, meetings and personnel to solve chemistry, medicinal chemistry, and molecular modelling challenges.

• Communicate and interact with other staff/team members in a professional and courteous manner.

• Operate in the lab in a safe and efficient manner according to HSE guidelines and adhere to all mandatory company compliance requirements.

About You

Basic Qualifications:

• Currently enrolled and pursuing a bachelor’s degree with Chemistry, biochemistry, or related field at an accredited college or university with the expectation that you will complete your current degree by the Spring of 2027

• Must be able to relocate to the office location and work 40hrs/week, Monday-Friday, for the full duration of the co-op/internship

• Must be permanently authorized to work in the U.S. and not require sponsorship of an employment visa (e.g., H-1B or green card) at the time of application or in the future. Students currently on CPT, OPT, or STEM OPT usually require future sponsorship for long term employment and do not meet the requirements for this program unless eligible for an alternative long-term status that does not require company sponsorship

Preferred Qualifications:

• Organic Chemistry and Physical Chemistry Courses completed, and with some computer programming or data analytics skills.

• Experience with data retrieval, integration, manipulation and visualization techniques and with at least one of the commercial molecular modeling software products such as Maestro, Discovery Studio, MOE and OpenEye/Cadence Molecular Sciences tools. 

• Experience in the use of at least one cheminformatics tool (e.g., Pipeline Pilot, Knime, Orion) to develop scientific workflows, analyze and visualize molecular properties and biological data as well.
