Tiny Health is advancing lifelong health, from the first 1,000 days to the last, and addressing chronic disease through precision microbiome science. Founded in 2020 and built by microbiome scientists and physicians, our testing platform reveals whether your microbiome is trending toward resilience or imbalances using shotgun metagenomics, proprietary AI, and one of the world's largest longitudinal datasets. Trusted by families and health practitioners alike, our research-backed gut and vaginal tests are redefining the microbiome as a cornerstone of personalized health through every life stage.

A mission that actually pulls people in
Most people here could be doing something easier. They’re not, because this work makes the microbiome measurable and actionable at every life stage — and the results land on real people who write in to tell us that we are life-changing to them. That feedback loop is the perk. It’s not just a job.Remote-first, real overlap
We’re a very diverse, international team, although we only hire FTEs in North America. Core hours are 9am–6pm CST, shiftable by up to two hours either way — start at 7am or 11am, wrap at 4pm or 8pm. Pick your window; just be findable in it.Written first, huddle second, meet last
Default to a clear Slack post: say whether you need a decision, an approval, or nothing at all. When a thread starts ping-ponging, jump into a huddle — ten minutes of voice beats forty of paragraphs. Meetings are the expensive option, so each one needs a decision to make, a preread or strawman sent ahead, and only the people who can actually make that call.Fast, but never sloppy
We ask “how do we do the two-month thing in two weeks?” — and then we check the work. We’re a health company: results, science, and anything a customer or practitioner touches get a second set of eyes, always. Moving fast and being careful aren’t in tension here; shipping errors isn’t speed, it’s rework.Shape what we build, not just how we build it
There’s no playbook waiting for you — you’ll write it, and that’s most true the more senior you are. Ideas get judged on whether they’re executed right, not on who raised them, and the person closest to the problem is usually the one who should be proposing the fix. Bring the alternative, not just the objection.Day One mentality
Fewer titles, fewer layers, fewer moving parts. Real process exists where it counts — data, lab, science, compliance, money — and we follow it, but process is a guardrail, not a destination. Process bloat is never the reason something didn’t ship.No hidden agendas
Transparency mean you’ll always understand how decisions are being made, especially at the top. We spend less time on politics and more on impact. Numbers, misses, and hard calls get shared openly. Feedback works the same way: in real time, not stockpiled for a review cycle. It’s a no-surprises culture: you should always know where you stand, and if you don’t, ask.High standards, genuinely fun people
Our CEO has been described as goofy but serious, direct but likable — and that sets the temperature. We take the work seriously and ourselves much less so. High-performing and fun to be around isn’t a contradiction; it’s the hiring bar.Is this pace for you?
We’re a venture-scaled company on a steep trajectory, and the pace is part of the job. There’s no deep bench to absorb the overflow, which is exactly why the scope here is bigger than it would be anywhere else at your level. We protect flexibility fiercely — more than half of us have kids — and ask for intensity in spikes, not as a constant grind. There’s no defined ladder. Perform, and you’ll move faster here than anywhere else.
