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 ML Engineering Team Lead at Aignostics, you will lead a high-performing team focused on building large-scale distributed training infrastructure and workflows using cutting-edge technologies for digital pathology, powering our state-of-the-art Foundational Model development. This is a hands-on leadership role where you'll spend approximately 50% of your time on technical contributions while guiding your team to push the boundaries of machine learning for cancer research and diagnostics. You'll own the full employee lifecycle for your team, drive technical roadmapping and ensure operational excellence while fostering a culture of autonomy and innovation.
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.
