Job description

About GenScript

Founded in 2002 in New Jersey, GenScript Biotech Corporation accelerates innovation in biotech and healthcare by providing researchers and companies with the building blocks needed to develop groundbreaking treatments and products. Guided by its mission to Make People and Nature Healthier Through Biotechnology, and its role as a well-recognized biotechnology company, GenScript has a team of approximately 6,165 employees and has served more than 200,000 customers across over 100 countries and regions.

Position Overview

We are seeking a highly motivated and experienced Principal Scientist in Bispecific Antibody Design & Engineering to establish and strengthen Singapore’s role as a center of excellence for complex antibody design and molecular engineering. In this role, you will serve as a functional leader in molecular design, format selection and recommendation, and engineering strategy while enabling improved expression, developability, and manufacturability. Additionally, you will play a key role in client-facing projects, ensuring seamless collaboration and delivery of high-quality biologics solutions. This position requires a blend of platform building, leadership skills, and the ability to build cross effectively.

Key Responsibilities

• Biologics Production Leadership: Develop, triage, implement, and troubleshoot innovative strategies for the design and engineering of complex antibody formats (bispecifics, multivalent, Fc-fusions, VHH). to achieve high yields, purity, and functionality.
• Design and manage a portfolio of projects to provide data-driven, structure-function insights to improve expression, stability, and manufacturability.
• Oversee a team of research associates and/or biotechnologists, providing technical guidance and fostering a culture of excellence in protein science methodologies.

Cross-Functional Collaboration

• Collaborate with cross-functional and cross-cultural teams to support the development of biologics, with a focus on evaluate and translate new technologies into production-ready solutions.
• Periodically review internal and external advancements in: Antibody formats and engineering strategies
• Upstream and downstream integration impacts driven by molecule design
• Assess readiness of new technologies for tech transfer, including:Fit-for-purpose application across different molecule classes
• Scalability and reproducibility
• Impact on quality attributes (aggregation, mispairing, heterogeneity)
• Act as a scientific bridge between R&D innovation and operational deployment, ensuring:New platforms are not only scientifically sound but also translatable to production workflows
• Design decisions are aligned with manufacturing realities
• Partner with internal stakeholders (e.g., Quality Assurance, Process Development, and Manufacturing) to ensure alignment and efficiency in biologics production workflows.

Develop Design-for-manufacturability Strategies And Internal Guidelines

Develop and integrate AI-assisted design-for-manufacturability frameworks, leveraging internal datasets and external computational tools (e.g., structure prediction, developability scoring) to proactively identify and mitigate risks such as aggregation, mispairing, and low expression in complex antibody formats.

Lead or support AI-enabled design and innovation initiatives (internal and external partnerships, including governmental or consortium projects) by translating computational design outputs into experimentally validated constructs, and ensuring alignment between in silico design predictions and real-world expression, quality, and manufacturability outcomes.

Innovation & Intellectual Property

Generate novel ideas and contribute to the company’s intellectual property portfolio by drafting scientific papers, filing patents and reporting innovations in scientific forums.

Contribute to the development of scientific publications, conference presentations, and webinars to showcase innovative findings and advancements.

Prepare and review technical reports and documentation to internal and external stakeholders.

Qualifications And Preferred Skills

• Ph.D., in Biochemistry, Molecular Biology, Cell Biology, Structural Biology, Bioengineering or a related field.
• At least 5 years of experience in antibody design, protein expression, and purification, preferably in an industrial setting.
• Strong expertise in bispecific design and troubleshooting expression challenges.
• A demonstrated record of success with protein engineering for enhanced protein expression or properties.
• Experience with the biophysical characterization of proteins and the assessment of protein-protein interactions.
• Familiarity with automation and high-throughput techniques for protein expression and purification.
• Strong analytical and problem-solving skills, with a wide ranging experience in analytical techniques such as SPR, and mass spectrometry.
• Excellent written and verbal English communication skills, with a track record of scientific publications, presentations, and conferences.

Benefits

• Benefits include medical, dental, and vision insurance as well as a 401(k) retirement plan with a company match that vests fully on day one.
• We offer paid parental leave after just three (3) months of employment, and a paid time off policy that includes vacation time, personal time, sick time, floating holidays, and company holidays.
• Additional benefits include flexible spending and health savings accounts, life and AD&D insurance, short- and long-term disability coverage, legal assistance, and supplemental plans such as pet, critical illness, accident, and hospital indemnity insurance.
• We also provide commuter benefits, well-being initiatives, and peer-to-peer recognition programs; demonstrating our ongoing commitment to building a culture where our people feel empowered, supported, and inspired to do their best work.
