In the Leyden Labs Research team, an opportunity has opened to cover maternity leave for a

TEMPORARY SR. SCIENTIFIC PROJECT MANAGER

to work from our office in Leiden, the Netherlands. We are seeking a highly organized, motivated, and energetic individual with project management experience who will thrive in a fast-paced environment with multiple competing priorities. You will help design experiments, think through analyses, and coordinate both on a logistical and technical level with CROs. Ideally, you have experience in the field of virology or antibody research.
More about the team:
You will play a central role in supporting scientific research efforts and growth within the Research team in the Research Department. You are going to report to Clarissa Koch, Chief Research Officer.
Why work with us:
This is an exciting role if you are not risk averse and you are keen to join a new, growing and ambitious company. You love being part of a team that is developing new products that protect us from current and future pandemics, and you like to provide day-to-day support to the company’s leadership. You have to be a person who understands what it means to live on the frontier, to seek new opportunities, and to share exceptional ideas.

This is what you will do on a daily basis and these are your responsibilities:

• Support, structure, and oversee the planning of external and internal research projects (both in vivo and in vitro), with a focus on the research team
• Write SOWs, agreements with external parties, manage strategic relationships, and support lab activities.
• You know how to start up and see a project through, from setting up contracts, material transfers, to chasing down orders and agreements, dealing with deviations, escalations, reporting and project closure.
• You have a level of understanding of scientific experimental design, e.g. with FACS, neutralization, ELISA based assays. Pre-clinical assay design experience is a plus.
• You have an excellent understanding of budgeting, ordering, and legal matters (latter is a plus!)
• Coordinate timelines and oversee deliverables and project outcomes while keeping up to date the project tracker
• Support the Scientists with experimental report writing and reviewing.

• You will be the first point of contact to external collaborators (CRO management) and the linking pin between (senior) scientists and CRO

An MSc with a scientific background, a PhD is preferred

• A minimum of 5 years of industry experience as project lead or project manager in a biotech or CRO organization
• Experience with Project Management software (e.g. Jira) is a plus.
• Project Management Certification is a plus.
• You have excellent verbal and written communication skills in English and preferable in Dutch as well.

More about you

• Open, flexible, and positive approach to work in a dynamic environment with different needs.
• You’re a highly organized, detail-oriented and independent individual
• You have the ability to manage multiple priorities and meet deadlines in a fast-paced environment
• You’re available for 32-40 hours per week from July 2025 until April 2026.
