About Us
You rarely get the chance to change an entire industry. But that's the position we find ourselves in. Join us, and you’ll help scale cures to patients that need them sooner.
We’ve developed fully-automated cell manufacturing sites powered by custom robotics - to scale therapies to millions of patients. Last year, patients were cured of diseases like Parkinson’s Disease and vision loss using stem-cell derived cells - but today these Regenerative Medicines are produced by hand, meaning they’re too expensive and hard to scale. With our automated CDMO, these therapies can now be scaled globally at low cost.
We've announced partnerships across multiple therapies so far ranging from Parkinson’s, to hearing loss, to bone repair - and raised $24m to expand into the market faster, and accelerate our development! Within the next 12-18 months, neurons grown on our machines will be going into Parkinson’s patient brains.
We’ve assembled a world-class team to take on this challenge, with ex-Dyson engineers and Nature-published scientists working hand-in-hand. You can learn more about your potential Mytos teammates here: Team
Mytos is backed by Y Combinator, the most successful startup program in the world which produced companies such as Airbnb, Dropbox, and Ginkgo Bioworks.
The Role
We are looking for a high-growth principal PD/MSAT Scientist to join our Biology team and push the limits of automation in cell therapy manufacture. This is a unique opportunity to learn how to execute projects at the interface of engineering and biology with a direct impact to patients.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
