About us:

Ascidian is redefining the treatment of disease by rewriting RNA.

Ascidian Therapeutics was founded to rewrite RNA by editing and replacing human exons. We were inspired by ocean creatures, called Ascidians, who are primordial ancestors of vertebrates. To grow from larvae to adults, ascidians re-engineer their transcriptome through RNA editing via trans-splicing and alternative splicing.

In our Brighton/Boston labs, RNA biology meets today’s cutting-edge genomics, computational biology, and deep-sequencing technologies to create a new class of medicines that address the underlying causes of disease. We welcome you to come join our vibrant team and help us lead the way into a new gene therapy era.

Who are we looking for?

We are seeking an experienced and highly motivated leader to join our dynamic team, responsible for overseeing all aspects of the chemistry, manufacturing, and controls-related activities, as well as managing clinical supply chain and manufacturing, for our RNA exon editing programs, ensuring the highest standards of quality, safety, and efficacy. This is a critical position, focused on innovative process, analytical, and technology development, that tightly collaborates with our internal teams and external partners, focused on early development &translational R&D, cGMP clinical supply, regulatory filings, quality, and the ultimate approval of medicines that will dramatically improve patient’s lives.

Your contribution to Ascidian:

  • Develops and oversees the implementation of comprehensive CMC strategies for our RNA exon editing programs, ranging from candidate nomination, first-in-human, and pivotal clinical studies to BLA with intended commercial process & analytics and appropriate control strategies.

    transfer to cGMP compliance externally.
  • Develops processes and analytics to support decisions and development timelines for our RNA exon editing programs.
  • Develops and manages the AAV capsid strategy, developing and maintaining academic collaborations, as well as identifying both internal and external opportunities to continue to innovate and develop competitive advantages.
  • Evaluates and implements novel technologies and processes to enhance product quality, manufacturing efficiency, and cost-effectiveness.
  • Lead CMC-related SOP development

What you need to succeed:

  • PhD in Molecular Biology, Biochemistry, Biotechnology, or a related pharmaceutical science field.
  • 8+ years relevant biopharmaceutical experience, with a focus on CMC and gene therapy product development. Direct experience with AAV gene therapy IND submission is strongly preferred.
  • Broad understanding of gene therapy and editing vector and drug product process and analytical development and a proven track record in CMC development for clinical stage programs.
  • Specifically experienced in adeno-associated virus (AAV)-based vectors, their design, production, quality, composition, and analytics.
  • A deep understanding of the cGMP manufacturing and regulatory requirements for gene therapy and editing products.
  • Entrepreneurial and passionate about innovative science and drug development, with strong resilience, agility and ability to manage ambiguity and make decisions with limited information and resources
  • A strong team player, present with the rest of the team contributing to the highly collaborative and fun culture, with ability to travel to visit external partners.
  • Excellent verbal and written communication skills and the ability to effectively work across levels, functions, and with both internal and external stakeholders.

As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

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.
