Head of Drug Substance & Analytical Development

Does it excite you to build something from the ground up, and do you have deep expertise in peptide process chemistry and leading high-performing teams? If this sounds like you, and you are ready to shape the future of peptide drug substance development at a fast-growing biotech, then you could be our new colleague.

Your new position Zealand Pharma is looking for a Global Head of Drug Substance - Senior Director, based in Boston. This is a rare opportunity to establish and lead a Peptide Process Development function from the ground up - building a Boston-based lab and team while providing global leadership across Drug Substance.

We offer exciting responsibilities:

• Establish and lead the Peptide Process Development lab in Boston, including hiring and developing a high-performing local team
• Provide global leadership and strategic direction for the Drug Substance function from early discovery to Phase 2
• Lead synthetic route scouting and salt selection, evaluating alternative processes with yield, COGS, manufacturability, and scalability as key decision criteria
• Develop and optimize upstream and downstream process design to establish scalable, cost-effective synthetic routes fit for initial clinical trials and as the foundation for Phase 3
• Partner closely with Analytical Development and Manufacturing to ensure processes are scalable, robust, and sustainable
• Drive technology transfer in collab with DK drug substance team to external CMOs, ensuring seamless transition from development to production

Your profile The ideal candidate brings a track record of scientific excellence in peptide process chemistry combined with the leadership presence to inspire and grow a team. A pragmatic problem-solver and strategic thinker, this person thrives in a dynamic, build-phase environment and can balance hands-on technical depth with cross-functional influence. Comfort with ambiguity and a bias for action are essential.

• Advanced degree (PhD preferred) in Chemistry, Chemical Engineering, or a related field, with extensive experience in peptide process development
• Demonstrated leadership experience managing and developing cross-functional or global technical teams
• Deep expertise in solid-phase and/or liquid-phase peptide synthesis, purification, and process optimization across Phase 1, 2 and 3 clinical stages
• Broad experience across the full process development cycle, including synthetic route scouting, salt selection, upstream and downstream process optimization, and evaluation of process alternatives with a focus on yield, COGS, manufacturability, and scalability
• Knowledge of process development and technology transfer to GMP manufacturing, including CMO management
• Experience defining manufacturing strategies from early discovery to Phase 2, with an eye toward building a robust foundation for Phase 3 and commercial
• Strong cross-functional collaboration skills, particularly with Analytical Development and Manufacturing

Your new team This role leads a globally distributed Drug Substance organization spanning two sites. In Boston, the role will establish a process wet lab staffed with process scientists focused on hands-on peptide process development and optimization. In Copenhagen, a DS team serves as the primary connection point to CMOs, ensuring alignment on manufacturing strategies, technology transfer, and day-to-day CMO oversight. Together, the two teams form a cohesive global function with complementary responsibilities, working in close partnership with colleagues across Research, Analytical Development, and Manufacturing.
