Staff Machine Learning Engineer

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 Staff Machine Learning Engineer at Aignostics, you will play a crucial role in shaping the technical direction and architecture of our ML platform and infrastructure. You will work hand in hand with fellow engineering leads at Aignostics, as well as collaborators in academia and industry. Your expertise will be instrumental in driving technical excellence across all ML engineering teams, ensuring we deliver high-quality, scalable solutions that transform complex biomedical data into actionable insights for cancer research and diagnostics. You will report directly to the Head of ML Engineering.

This is a unique opportunity to join a fun, diverse and growing team of 100+ software engineers, applied scientists, biologists and pathologists to shape the next generation of cancer treatments. You will be part of a dedicated 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 on significant responsibilities 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.
