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.

Remote-First Company: our working hours follow a 2 hour window from 9 am - 6 pm CST

Driven by an ambitious mission: we're reinventing how we should think about wellness from the first 1,000 days to the last

Shape what we build, not just how we build it : we prioritize experimentation with taking ownership, and moving fast

No hidden agendas : we operate with full transparency because when everyone's working from the same honest picture, you spend less time on politics and more time on impact

High standards, human culture: we hold ourselves to a high bar and do it alongside a team who can laugh at themselves and make the hard days genuinely enjoyable

Learn fast, be better What that looks like: You deliver your output when it creates value, not when it’s perfect. After, you continuously monitor it and improve it over time.

Be relentlessly resourceful What that looks like: When faced with a blocker, you map three alternative solutions, highlight your favourite, justify why, and seek quick feedback from your team.

Think like an owner What that looks like: When something needs to get done, you own it, communicate cross-functionally, and see it across the finish line.

Act with honesty and empathy What that looks like: When a colleague shares an idea that carries real risk, you challenge it in the moment and do it with kindness.

Delight people by anticipating their needs What that looks like: You put yourselves in the shoes of the customer or collaborator before presenting an idea, process, or proposal, and curate your communication to address their pain points.
