1) Why us?

We believe that AI has the potential to revolutionize how cancer and other complex diseases are diagnosed and treated. We also believe that AI is a tool, not an identity – without access to high quality data and a scientifically rigorous, transparent approach to model development, AI is just a buzzword. That’s where we come in.

Aignostics is a spin-off from one of Europe's largest and most prestigious university hospitals (Charité), with employees in Berlin and New York. We have received over $50M in funding from leading investors and are a growing team of over 100 interdisciplinary professionals. We work with academic partners as well as leading global life sciences companies.

As a Senior Frontend Engineer at Aignostics, you'll develop a cutting-edge digital pathology platform that transforms complex biomedical data into actionable insights for cancer research and diagnostics.

You'll build features for diverse users, optimize performance, and collaborate with various teams including product, design, backend, ML engineering, and DevOps. Beyond driving platform architecture and maintaining engineering standards, you'll foster a culture of ownership and collaboration while mentoring junior engineers.

This is a unique opportunity to join a fun, diverse, and growing team of 100+ data scientists, software developers, biologists, and pathologists to shape the next generation of cancer treatments. You will be part of a driven community that works in an agile, supportive and interdisciplinary research environment where your results make a difference to patients. In our established startup you have the opportunity to grow personally and technically, take responsibility and benefit from a dynamic work environment.

At Aignostics, we believe that fighting cancer is a job for people of all identities, backgrounds, and cultures. We value and celebrate diversity and inclusion and are committed to offering equal employment and promotion opportunities for all applicants and employees. Applicants will be considered regardless of their age, disability, ethnicity, race, gender identity or expression, sexual orientation, religion, etc. We thrive through collaboration and believe the more inclusive we are, the better our work will be.
