About Us
Ridge Biotechnologies enables the development and construction of the next generation of precision medicines through enzyme and targeted therapeutic design. Using our powerful experimental and computational platform built on large datasets generated by cell-free synthesis, bioorthogonal chemistries, and ever-improving machine learning models, Ridge Bio is developing new medicines and scalable production methods that enable our partners to bring lifesaving biotherapeutics to patients in need.
Ridge Bio’s founders are industry veterans who have previously built successful biotechnology companies and academic leaders from top institutions including Stanford and MIT with world-leading expertise in cell-free systems, therapeutic development, and protein engineering. We are backed by Sutter Hill Ventures, a quiet powerhouse that has been building successful companies since 1962 by focusing on bringing together great people to solve hard technological problems in big markets. Our company culture is dedicated to intellectual integrity, service ownership, and creative impact.
Role Description
We are looking for an experienced business development leader to join Ridge Bio as our Chief Business Officer. Reporting directly to the CEO, you will focus on identifying and closing external partnerships with major pharmaceutical companies, emerging biotechs, CROs, and CDMOs to put to our three core product lines to work - NativeLink™ (site-specific antibody bioconjugation for ADCs without modifying the antibody sequence), ProTrigger™ (ML-designed linkers for tissue and tumor microenvironment-specific payload release), and Catalytic Medicines™ (enzyme-based therapeutics).
You’ll complement a brilliant scientific and operational team at the cutting edge of precision medicine design. Ideal candidates for this role have spent years initiating, structuring, and closing major licensing deals. You will bring a network, a deal track record, and scientific fluency that lets you represent our platforms credibly to R&D and corporate development counterparts at the world’s leading life sciences organizations. We are open to working with the right person to find an arrangement that fits their situation (an initial engagement of 25-50% effort is highly preferred).
Required Qualifications
How You’ll Contribute
We offer competitive compensation, meaningful equity, and a chance to achieve high impact by building upon a differentiated set of technologies. If you have spent your career closing meaningful deals in the ADC or precision biologics space and are looking for a high-impact BD role at a company solving compelling problems found across the industry, this is the role for you.
