Full Stack Software Engineer (Python/React) (f/*/m)
This is Cradle
Proteins are the molecular machines of life, used for many therapeutic, diagnostic, chemical, agricultural and food applications. Designing and optimizing proteins takes a lot of expert knowledge and manual effort, through the use of custom computational and biological tools.
Machine learning is revolutionising this space, by enabling high‑fidelity protein models. At Cradle, we offer a software platform for AI‑guided discovery and optimisation of proteins, so that biologists can design proteins faster and at scale. We are already used by clients across pharma, biotech, agritech, foodtech, and academia.
We're an experienced team of roughly 60 people. We've built many successful products before and have enough funding for multiple years of runway. We are distributed across two main locations, Zurich and Amsterdam, and are focused on building the best possible team culture.
We offer our employees a very competitive salary, a generous equity stake (for full time employees) in the company and a wide range of benefits and career progression opportunities.
What we are looking for
We're looking for full stack software engineers who are excited to peek out of the virtual world and join us on designing a platform for optimising biological systems! Be ready to witness first hand what happens when you leave the bits and bytes behind and try to solve challenges with nature’s constraints and complexity.
Your responsibilities
As a full stack software engineer, you will be responsible for designing and developing a service‑oriented decoupled web application, which exposes our advanced machine learning models to scientific end users. For example, this means:
* Implementing lightweight and modularised web‑based user interfaces and visualisations, e.g. to rapidly prototype new UIs as new API endpoints become available.
* Architecting database designs to effectively store customer data, e.g. with consideration for how to represent the variability of biochemistry in future‑proof ways.
* Owning large parts of the software design and development process. We are in an early stage of the company where you will majorly contribute to the software design of the product.
* Building modern documentation stacks which automatically stay up‑to‑date, e.g. through pulling in OpenAPI specifications.
* Collaborating with biologists, machine learning experts, and scientists alike, and becoming skilled in working in their domains.
Your skills
Must haves
* Familiarity with designing user interfaces and are familiar with one or more popular frameworks (e.g. React).
* The Python programming language and its ecosystem. (FastAPI, uvicorn, ruff, pyright, …).
Nice to haves
* Excitement about all parts of the software stack which is reflected in your past projects. At any given day you could be asked to design a REST API, contribute to a codon optimiser*, or design a UI plugin.
* Databases and big data systems.
* Production systems for machine learning applications.
* Building containerised backend systems. (Docker, Kubernetes).
* You are kind and work well in teams. We look for team players and excellent communicators who contribute to a positive and friendly working environment.
* Do a little research online if you don’t know what this is – please feel free to check it out.
Notice about recruitment scams
Please be aware that scammers are posing as us in order to get your personal details or money. We only communicate via @cradle.bio email addresses, we only make job offers after having met you in person at our office in Zurich or Amsterdam, and we never ask you to pay for anything during the interview process.
