Turning breath into insights
At Halitus, we’re passionate about building diagnostic technology that frees humanity from debilitating diseases. We aim to make diseases from COVID-19 to cancer detectable within less than a minute, conveniently and non-invasive. If you get excited about shaping a future of healthcare that is proactive, intuitive to use, sustainable, and cost-effective, we'd love for you to join us. We’re an award-winning, purpose-driven Berlin-based DeepTech Start-up led by engineers and a doctor, supported by Roche’s RoX and backed by renowned investors.
We’re looking for a Backend Developer who will be responsible for backend development, backend security systems, data verification and anonymization systems, data storage and collection systems.
