About the Role

Cancer doesn’t care how it disrupts the course of lives. We do. Since our founding, we have pursued one goal: develop targeted cancer therapies to improve outcomes for cancer patients. This singular focus has positioned us as a leader in the expanding field of antibody-drug conjugates (ADCs) for the treatment of cancer. At ImmunoGen, each of us is driven by a shared conviction that by advancing precise, targeted cancer therapies, we have the power to offer more good days to patients and their families ― now. It is why we come to work each and every day, and it is what will continue to motivate and energize us in the years to come.

ImmunoGen is currently looking for an individual to join our Technical Operations team as a Development Associate, Analytical Development. The successful candidate will be responsible for supporting analytical method lifecycle activities at contract testing laboratories (CTL) and contract manufacturing organizations (CMO) for late-phase antibody-drug conjugate (ADC) development. The candidate will support CMC activities to enable filing and commercialization of multiple ADC programs.

  • Supporting validations, re-validations, transfers, trending/monitoring, optimization, troubleshooting, etc. for large and small molecule methods (release, stability, and in-process control) maintained at CMOs and CTLs

  • Supporting reference standard management for small molecules and biologics, including qualification and re-qualification activities

  • Authoring and reviewing all documentation (protocols, reports, test methods) related to the activities above; collaborating closely with QA to ensure applicable requirements are met (GMP, ICH, compendial)

  • Authoring change controls for analytical-related changes and supporting deviation/excursion management

  • Authoring and reviewing regulatory filings (BLA, MAA, PAS), and drafting responses to questions from health authorities during review

  • Supporting specification setting (release and stability) for drug product, drug substance, and drug substance intermediates (monoclonal antibodies and small molecules)

  • Serving as analytical representative on CMC team and working closely with process development, formulation development, manufacturing sciences, quality assurance, regulatory CMC, and supply chain to support program objectives

Life at ImmunoGen

At ImmunoGen, we are looking for forward-thinking talent with diverse experiences and a track record of success, leadership skills, a demonstrated ability to take initiative, and a passion for improving the lives of those living with cancer. To succeed here is to care ― care about what we do, why we do it, and each other. We are working hard to bring hope to our patients and their families, which inspires our teams to aim high and honor our commitment to continuous improvement.

At ImmunoGen, collaboration is not a construct. It is at the core of everything we do and shows up in how we work every day. Here, your ideas and experience matter. We value driven individuals who thrive in a fast-paced environment; who can think about our future and see the promise before us; who anticipate risks and opportunities; who are willing to learn and adapt to change; who are inclusive and eager.

Together, we rise to the challenge before us, advancing our programs on the strength of our deep scientific and commercial expertise and energized by the opportunity to change long-standing treatment paradigms. We pride ourselves on the work that we do, and know that it is a privilege to work in the oncology space and to dedicate our days to helping patients.

Our Unique Opportunity

It’s an exciting time for our organization. The US FDA recently granted accelerated approval for ELAHERE™ (mirvetuximab soravtansine-gynx) for the treatment of folate receptor alpha (FRα)-positive, platinum-resistant ovarian cancer, marking our transition into a fully-integrated oncology company. This is just the beginning, as we embark on an exciting new chapter as a leader in the development and commercialization of innovative oncology products.

Joining ImmunoGen now will give you the unique opportunity to create a lasting impact ― to make your mark on the work that we are doing by leveraging your experience to shape our first commercial launch and the go-forward organization.

  • BS or MS in chemistry, biochemistry, or closely related discipline

  • At least 4 years of experience in analytical development or quality control supporting antibody or ADC therapeutics in a GMP environment

  • Strong knowledge of GMP requirements, ICH guidelines, and compendia (USP and Ph. Eur.)

  • Excellent verbal and written communication skills

  • Experience working with contract organizations (CTLs and CMOs) preferred

  • Experience with statistical software (e.g., JMP, Minitab) preferred

Our Benefits

We believe in the potential of our people and foster a supportive environment that develops our folks, rewards performance, and incentivizes long-term success. From excellent benefits and competitive compensation to ownership in the company, we want to inspire our employees.
