About The Position

Marea Therapeutics is a clinical-stage biotechnology company focused on developing first-in-class therapies for cardioendocrine diseases. The company has a growing pipeline, with its lead program, MAR001, for severe hypertriglyceridemia, approaching Phase 3 development. Their second asset, MAR002, a monoclonal antibody for acromegaly, is progressing into Phase 2/3 development. Marea fosters a collaborative, dynamic, and hands-on environment where every team member's contribution is valued. This role is a key position within the Technical Operations team, reporting to the VP of Technical Development, and is crucial for advancing the company's programs towards late-stage development. The company operates in a lean environment, leveraging CDMOs and consultants to achieve CMC development goals. The successful candidate will be hands-on and adaptable to the evolving needs of a startup.

Requirements

Specific experience with developing, scaling up, tech transferring downstream processes for CHO-derived monoclonal antibodies.
Previously experience of having worked with CDMOs with scope of work in process development, tech transfer and scale up.
Direct experience with at-scale manufacturing processes and equipment either through previous tech transfers or direct manufacturing operations experience.
Demonstrated ability to independently write technical reports based on sound data analysis and experimental design.
Demonstrated understanding of overall drug development workflow and how CMC can enable acceleration of drug development in a cross functional environment.
Knowledge of cGMPs, especially as related to a virtual environment where manufacturing is currently outsourced to third party vendors.
Excellent professional and interpersonal skills, especially for developing and maintaining relationships with CDMO’s.
Excellent oral and written communication skills.
Ability to work efficiently and cooperatively in-person or virtually (both at Marea or a CDMO site).

Demonstrated understanding of the product attributes and analytical methods to guide process development, improvement.

Nice To Haves

Previous experience/familiarity with other aspects of bioprocess development (cell banking, cell culture, formulation and analytical).

Responsibilities

Develop downstream process conditions with key parameters specified, leveraging the CDMO process platform adapted to our specific monoclonal antibody.
Identify, evaluate, and qualify unit operations, raw materials, equipment, sampling plan and in-process testing and overall control plans for the downstream process (Seed train, inoculum train, bioreactor and harvest) with thoughtful integration into the overall manufacturing process from seed train to final vial.
Design and oversee studies/activities necessary for process optimization and continuous improvement to assure robust and cost-effective manufacturing processes.
Provide technical oversight of the development and manufacturing activities at the CDMO.
Develop process and control strategies with an eye towards consistent and reproducible manufacturing processes and final drug substances.
Support manufacturing deviations, OOS, investigations, root cause analysis, and CAPAs, as necessary.
Manage and execute troubleshooting activities, as necessary.
Transfer manufacturing operations to new CDMOs as part of the overall project plan to ensure supply chain reliability.
Support the Drug Product Process Development group with material supply and some analytical support.
Develop technical content suitable for internal quality processes and regulatory submissions.
Contribute to preparation and review of regulatory documents for submission to FDA and other regulatory authorities.
Identify and utilize expert consultants to help address key technical questions.
Build and maintain a strong cooperative working relationship with colleagues in Drug Product, Analytical, Quality, Regulatory, Clinical Development, Project Management, and Legal.
Travel to CDMO sites (Average up to 20% of the time with peak needs during certain critical windows).
Internal laboratory work, not expected immediately, but may be needed in the future.
Develop cost model for the downstream process.
