Job Description

R&D Process Engineering, a part of AbbVie’s Development Sciences organization in Synthetic Molecules CMC (Chemistry, Manufacturing, and Controls), is responsible for designing and developing scalable processes to make drug substances and drug products, including small molecules and antibody drug conjugates (ADCs), throughout pre-clinical and clinical development stages.  Responsibilities include synthetic route design, process definition, scale-up, and tech transfer for wide varieties of therapeutics and technologies to meet evolving pipeline demand.  The R&D Process Engineering team also partners with Biologics CMC Development and Aesthetics R&D functions to provide active engineering support to enable robust process scale-up and manufacturing of biologics drug substances and drug products including toxins, lipid nanoparticles (LNP’s), and cosmetic active ingredients (CAIs). We contribute to the development of innovative engineering technologies and create valuable intellectual property through the composition of matter, chemical processes, and technologies resulting in cost-effective commercial manufacturing processes. We support the development of the supply chain for pipeline molecules and help prepare and defend CMC regulatory content.

Chemical Engineers within Process Engineering support pipeline projects through all phases of development. Early in development, engineers focus on establishing an enabling process that can be scaled-up successfully. In the later stages of development, engineers optimize the drug substance and drug product processes and lead manufacturing campaigns. Engineers also work cross-functionally to transfer the optimized process to manufacturing sites, develop control strategies, and prepare reports to support regulatory filings.

Role Overview

The successful engineering candidate will play a key role in the R&D Process Engineering function. The core deliverable of R&D Process Engineering is to develop robust manufacturing processes and advance innovative technologies using strong engineering fundamentals.  Key requirements for this role include a demonstrated capability to model antibody drug conjugate kinetics and mechanisms, experience with drug linker and drug substance process design, development of flow chemistry reactor platforms, including in use for ADC’s, experience with highly potent compound handling, leadership of novel reactor configuration development (e.g., photochemistry, electrochemistry, membrane reactors, etc.), and expertise in computational fluid dynamics to support reactor design and tech transfer.  The candidate must have prior reaction development and scale-up experience with demonstrated examples of scale up of ADC processes, including reaction and purification.

The candidate is expected to lead the identification and development of novel approaches and technologies to enhance process development efficiency and commercialization throughout existing and new modalities in Development Sciences, including small molecules, ADC’s, lipid nano-particles, and toxins. The candidate must exhibit a collaborative nature in identifying process challenges on a wide range of projects in the Drug Substance and Drug product space, take part in a cross-functional team to deliver specific project needs, and take on a leadership role in developing and implementing solutions.

Key Responsibilities:

Develop robust manufacturing processes, supporting assets through all phases of development.

Participate in and/or lead project teams towards development and characterization of new small and large molecule assets. Establish, communicate, and execute research plans.

Develop commercial ready manufacturing processes in the laboratory and demonstrate the processes in the pilot plant.

Set project strategies, define project responsibilities and timelines, and provide leadership in a matrixed team setting.

Address challenging problems with chemical and biochemical reactions, separations, and/or isolations using demonstrated expertise in reaction kinetics, transport phenomena, and mathematical modeling.

Develop and apply process analytical technologies and data-rich experimentation tools to build appropriate reaction and process understanding via model-guided experimentation.

Build data driven and knowledge driven models to facilitate successful scale-up and tech transfer.

Author and/or review technical documents summarizing process development efforts and contribute to regulatory filings.

Exhibit a collaborative nature in identifying process challenges on a wide range of projects and communicate findings and recommendations effectively by multi-disciplinary interactions with organic chemists, analytical chemists, process development engineers, pilot plant engineers, drug product development scientists, program managers, and regulatory affairs specialists.

Author publications and present at scientific conferences.

Qualifications

BS, MS, or PhD in Chemical/Bio Engineering or a related field and 12+ (BS), 10+ (MS), or 4+ (PhD) years of relevant industrial experience.

Candidates are expected to have a strong background in chemical engineering and the proven ability to demonstrate their skills in this field.

Demonstrated capability to model antibody drug conjugate kinetics and mechanisms

Experience with drug linker and drug substance process design, including tech transfer and scale-up

Development of flow chemistry reactor platforms, including in use for ADC’s

Experience with highly potent compound handling

Leadership of novel reactor configuration development (e.g., photochemistry, electrochemistry, membrane reactors, etc.)

Expertise in computational fluid dynamics to support reactor design and tech transfer

The candidate is expected to demonstrate the ability to solve difficult technical problems and champion new technologies to achieve project goals.

The candidate is required to be a strong team player and demonstrate scientific leadership, possessing effective oral and written communication skills for facilitating collaborations and leading cross-functional process development teams.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
