About Mytos

You rarely get the chance to change an entire industry. But that's the position we find ourselves in. Join us, and you’ll unleash scientists, accelerate their research and help get cures to patients sooner.

We’ve developed machines to fully automate human cell production - the most manual process in Biotech. Cells are used to discover and develop new drugs, and now they're being used to cure diseases like Parkinson’s and age-related blindness. Mytos will impact cure development across the board.

We're live in multibillion dollar biotechs on both coasts of the US, and raised $19m to expand into the market faster, and accelerate our development! Next year, neurons grown on our machines will be going into Parkinson 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

As a Junior/Mid level Software Engineer (depending on experience) you’ll be contributing across all areas of our full-stack product based in the Cloud, and our IoT devices that interface with Mytos hardware to manufacture cells. You'll contribute across a variety of technologies and paradigms, leaning how to research, design, implement, maintain, and evolve product functionality giving users powerful tools to customise and monitor cell growth protocols.

Your work will directly impact how quickly and effectively new therapies and research tools can be developed, ultimately helping patients worldwide.

What You'll Do

Collaborate closely with other engineers to deliver end-to-end product functionality spanning experiment scheduling, automated image analysis, and remote operation of our devices.
Develop and improve our frontend applications using TypeScript, React, and GraphQL to create intuitive interfaces for complex biological workflows.
Build backend services that communicate with our hardware systems and learn about data integrity throughout the cell manufacturing process.
Collaborate across disciplines with hardware engineers, biologists, and commercial teams to build reliable and effective systems in record time.
Learn and contribute to our testing methods to help us deliver quality software at speed.
Learn and contribute to architecture and infrastructure, system performance, and interesting distributed system challenges.
Write code that you can immediately see the real-world impact: testing on our prototype machines in our own lab.
Up-skill in domains outside software engineering, from donning a lab coat and be trained on the nuances of stem cells, to the basics of fluid mechanics.
Be given a lot of autonomy, responsibility, and ownership of product problems and the technical solutions you design and deliver to address customer needs.

What We're Looking For (depending On Experience Level)

Are early in your software career and want to join an environment that gives you the chance to grow quickly
Have demonstrated technical promise so far in your studies or work
Want to work on difficult technical challenges in a field that will define the biggest scientific advancement this century
Self-starter attitude with a drive for producing quality work.
Care and compassion for customers and colleagues.
Experience with full-stack web development using TypeScript or other typed languages.
Experience with modern frontend frameworks (React preferred).
Experience with backend development and API design (Node.js preferred).
Experience working with databases (PostgreSQL and Prisma or similar ORM experience ideal).

Our technologies

Frontend (Netlify): React, TypeScript, GraphQL, Storybook
Backend (AWS & Heroku): NodeJS, TypeScript, GraphQL, MQTT, PostgreSQL, Python, Pulumi IaC
Physical Device (on-premise): NodeJS, Typescript, FastAPI, Python, MQTT
Firmware: C++, GTest, GMock, Bazel, Platformio

Nice-to-Haves

Understanding of distributed systems concepts.
Experience with Python for data processing or image analysis.
Background or interest in biology, lab automation, or scientific instrumentation.
Any experience with regulated environments (GMP, HIPAA, etc.)
Any experience with UI/product design processes and tools (wireframes, mockups, looks-like prototypes, etc.).

Why You'll Love Working Here

Impact : Your work will directly enable the production of cell therapies that can transform patients' lives.
Growth : We're solving complex problems at the intersection of software, hardware, and biology—you'll constantly learn and develop new skills.
Autonomy : You'll have the freedom to shape our approach to GMP readiness, with support from a talented cross-disciplinary team.
Team : Work with the best engineers and scientists in a collaborative environment where diverse perspectives drive innovation.

About the Company

Mytos builds robots that grow human cells. Our machines take stem cells as input, and grow them into specific cells like neurons or heart cells. Customers use our platform to scale stem-cell derived therapies to more patients sooner. We're also used to produce cells for testing new drugs on during R&D in Drug Discovery. Mytos is backed by leading investors, including YCombinator, Buckley Ventures and IQ Capital - as well as founders and execs from companies like Kite, Sana, Dropbox, and Revolut. Our team is made up of bri... Know more
