Arcana is building new AI-powered technologies that enable long-term human health monitoring through label-free protein detection and proprietary photonics technology, designed to support health monitoring at home. By combining photonics and artificial intelligence, Arcana reads biological signals directly—without labels or reagents—making it possible to generate continuous insight into health over time. Instead of relying on infrequent lab tests or reacting to late-stage symptoms, Arcana focuses on capturing early biological signals that reflect how the body responds to everyday physiological processes such as stress, recovery, and aging. Our mission is to support long-term health and longevity by shifting healthcare from reactive treatment to proactive insight. We believe health should be understood as a trajectory rather than a snapshot, and that high-quality biological data is the foundation for better decisions, more timely interventions, and healthier lives. Arcana is a deep-tech company operating at the intersection of photonics, biology, and artificial intelligence. We work on challenging problems that demand scientific rigor, long-term thinking, and close collaboration across disciplines. Our work spans hardware development, software engineering, data science, and applied biology, with a shared focus on translating complex biological signals into meaningful, real-world impact. If you are motivated by first-principles thinking, enjoy working across boundaries, and want to help shape the future of health and longevity, we invite you to apply.
