Christian Mueller, CDO at Immutep on Career Crossroads, Culture Missteps, and the Recruitment Disconnect in Biotech

In this episode, I talked with Christian Mueller, Chief Development Officer at Immutep. Christian’s path into biotech wasn’t exactly planned—from summarizing VC business plans during his studies to becoming a driving force behind the world’s first Claudin 18.2-directed antibody.

We talked about the wins and the setbacks: from finally securing Pembrolizumab supply after years of rejections, to those painful moments when you give your all to a project, and still feel unseen. Christian also opened up about hiring, leadership, and what makes a biotech team truly work (or fall apart). He shared why Immutep has gone all-in on LAG-3, what makes their international culture different from most, and why knowing your weaknesses might just be the most underrated leadership skill.

And to wrap things up, we threw in a few quickfire questions, from the book he’s reading (featuring octopuses!) to what he tries to do every single day to stay sharp.

Here’s what you’re in for:

• The red flag that made Christian walk away from a company
• Why great hiring is about cultural fit, not just perfect CVs
• What small biotechs misunderstand most about recruitment

About me

My name is Charles Spence and I lead Discera. After many years working in the life-science recruitment world, I decided to work for myself. Before doing recruitment I graduated with a biomedical degree, have worked in hospitals (including translation work in Seoul, South Korea), and also spent a year working in diabetes research in Stockholm. After doing research and travel, a career in business and science felt the most appropriate.

In 2023, I decided to launch my firm - Discera Search. A firm committed to solving the biggest talent needs of early clinical stage SME biotechs on the East Coast and DACH.
