Associate Director, Drug Substance Process Development

New Haven, CT (Northeast Preferred)

ABOUT US

There are more than 9 million immunocompromised people in the United States. Almost half a million of those represent a population that are moderately to severely immunocompromised and at highest risk for severe COVID-19, including stem cell and solid organ transplant patients as well as those with hematologic cancers.

At Invivyd, Inc., we take those numbers very seriously and we come to work each day on a mission to deliver protection from serious viral infectious diseases, beginning with SARS-CoV-2. Invivyd deploys a proprietary integrated technology platform unique in the industry designed to assess, monitor, develop, and adapt to create best in class antibodies.

In March 2024, Invivyd received emergency use authorization (EUA) from the U.S. FDA for a monoclonal antibody (mAb) in its pipeline of innovative antibody candidates.

In October 2025, the FDA cleared the company's Investigational New Drug (IND) application and provided feedback to advance the company's REVOLUTION clinical program, Invivyd's development program for VYD2311, a vaccine alternative monoclonal antibody being investigated for the prevention of COVID-19.

Location: New Haven (Northeast Preferred)

Position summary:

While the candidate brings strong scientific capability and experience in platform development, their background is primarily focused on early-stage CMC and discovery/preclinical work. This role reports to the Head of Process Development and Manufacturing and is responsible for oversight and execution of drug substance process development activities at Invivyd’s Contract Manufacturing Organizations (CMOs), including technology transfer, process scale-up, process characterization, process validation, and support of clinical and commercial manufacturing supply.

As such, the position requires deep, hands-on expertise in drug substance development, particularly in downstream purification process development and its integration with GMP manufacturing operations. It also requires demonstrated experience in external manufacturing oversight, technology transfer, and late-stage/commercial readiness, which were not sufficiently represented in the candidate’s background.

Additionally, the role requires meaningful experience with small- and large-scale downstream processing equipment, which also appears limited.

Responsibilities:

  • Provide technical leadership and oversight for drug substance process development activities, including process design, scale-up strategy, and technology transfer to CMOs
  • Serve as a subject matter expert for upstream and downstream process development, with particular emphasis on downstream purification strategy, process robustness, and scalability
  • Lead the design and execution of process characterization, process performance qualification (PPQ)-enabling studies, comparability assessments, and impurity control strategies to support clinical and commercial readiness
  • Define and translate process requirements into development reports, control strategies, and technology transfer packages to enable successful execution at external manufacturing partners
  • Collaborate with CMOs to ensure effective process transfer, scale-up, and process validation readiness, providing scientific and technical guidance rather than direct manufacturing oversight
  • Critically evaluate process and analytical data to identify risks, optimize performance, and resolve technical challenges throughout development
  • Develop and maintain strong relationships with external partners (CMOs, CROs, raw material suppliers, and consultants), ensuring alignment on development strategy and execution
  • Partner cross-functionally with Analytical Development, Quality, Regulatory, and Supply Chain to align on control strategy, specifications, and overall CMC strategy
  • Contribute to CMC regulatory submissions, including authoring and reviewing drug substance sections (INDs/IMPDs, BLAs/MAAs, and supporting documentation)
  • Identify program risks and critical path activities, and proactively develop mitigation strategies to ensure successful progression of development programs
  • Ensure that processes are designed for cGMP compliance and are aligned with FDA and EMA expectations, with clear line of sight to commercialization

Requirements:

  • BS/MS in Chemical Engineering, Biochemical Engineering, Pharmaceutical Engineering, or related scientific discipline, with 10–15 years of experience in biopharmaceutical or biotechnology industry, including process development, scale-up, and technology transfer
  • Demonstrated experience in drug substance process development for biologics (preferably monoclonal antibodies), with strong emphasis on downstream purification development, including chromatography, filtration, and viral clearance strategies across small- and large-scale systems
  • Proven track record in process scale-up, process characterization, and development of control strategies to support late-stage clinical and commercial readiness
  • Extensive experience leading and supporting technology transfer to CDMOs, including preparation of technical packages and ensuring successful process implementation at external partners
  • Demonstrated ability to effectively manage and influence CDMOs from a development perspective, ensuring alignment on process performance, timelines, and deliverables
  • Strong knowledge of cGMP principles, ICH guidelines (Q8–Q11), and global regulatory expectations (FDA, EMA/CHMP) as they relate to process development and commercialization
  • Experience supporting CMC regulatory filings, including authoring or reviewing drug substance sections for INDs/IMPDs and BLAs/MAAs
  • Highly motivated, decisive, and results-oriented, with the ability to drive development programs in a fast-paced, matrixed environment
  • Strong communication and leadership skills, with demonstrated ability to collaborate cross-functionally and communicate effectively with external partners, senior leadership, and stakeholders
  • Proven problem-solving capability with the ability to analyze complex process data, identify risks, and implement effective mitigation strategies
  • Willingness to travel (up to ~20%) to support technology transfer activities and key development milestones at CDMOs
  • This role will require the ability to work in a hybrid capacity, once per week in the HQ office

Form CC-305
Page 1 of 1

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
