Does it excite you to combine a strong scientific mindset with innovation to drive drug substance (DS) strategy and process development for peptide-based active pharmaceutical ingredients (API), and do you have experience partnering with external DS manufacturing organizations (CMOs)? If this sounds like you, and you are ready to take on a broad area of responsibilities, then you could be our new colleague.
Your new position
As a Senior Drug Substance Scientist, you will be the professional anchor and subject-matter expert for drug substance activities from early research through Phase 2. The role is central to defining DS strategy, driving process development with external CMOs, and ensuring processes are robust and scalable. You will be empowered—and expected—to take full ownership of your area and drive scientific decision-making in close collaboration with cross-functional CMC stakeholders.
We Offer Exciting Responsibilities
- Evaluate new technologies and approaches for DS manufacturing
- Drive DS process development with internal process laboratory support and CMOs to deliver preclinical, Phase 1 and Phase 2 supply, and mature processes toward Phase 3 in collaboration with late stage colleagues
- Key player in the collaboration with DS CMOs, including day-to-day communication and oversight, follow-up on project timelines, documentation review, knowledge transfer, and scoping of process development
- Contribute to risk assessments, critical process parameters (CPP), and scoping process development at the CMO
- Represent DS in cross-functional CMC teams and drive scientific and strategic input to clinical trial applications and regulatory interactions in collaboration with Regulatory Affairs
Your profile
A strong scientific mindset and deep understanding of process chemistry are key to succeeding in this role. The ideal candidate takes ownership, works in a structured way, and thrives in a dynamic environment with evolving needs and priorities. Strong collaboration and stakeholder management skills are essential, given close interaction with CMOs and cross-functional teams.
- M.Sc. or PhD within chemistry, biochemistry, pharmaceutical sciences, or another relevant field
- +5 years of experience from the pharmaceutical industry
- Experience from DS process chemistry laboratories and process development activities
- Experience with solid-phase peptide synthesis and contributing to process optimization
- Experience with other fields of synthetic chemistry such as antibody-drug conjugates, liquid-phase peptide synthesis, and small molecules is an advantage
- Experience with outsourcing of DS/API production at CMOs, including technical oversight and review of CMO documentation
- Experience with regulatory aspects of CMC work and Good Manufacturing Practice (GMP), and strong oral and written communication skills in English
Your new team
You will be joining a department of approximately 25 people, with a DS specialist area currently consisting of 2 DS specialists. The team works closely both within and across departments with a shared goal of enabling projects and helping colleagues succeed through collaboration, knowledge sharing, and strong day-to-day teamwork.
