The Opportunity

As Lab Manager, you will oversee the day-to-day operations of Tiny Health's St. Louis laboratory while serving as a key contributor to our microbiome research and development efforts. This is a hands-on role for an experienced scientist who enjoys both bench work and laboratory leadership.

You will independently manage laboratory workflows including microbial culturing, DNA extraction, sequencing library preparation, sample processing, and protocol execution. Beyond maintaining efficient laboratory operations, you will help develop and optimize new protocols, design and execute experiments, analyze results, and contribute to advancing our microbiome science initiatives.

We are looking for someone who is highly organized, resourceful, and comfortable operating with significant autonomy. The ideal candidate enjoys solving problems, building systems, and taking ownership of both scientific and operational outcomes. This position reports directly to the Chief Science Officer and works closely with our broader science team.
