Algorithm & Analytics Developer

Vire Health Oy is a Finnish health-tech company that helps people time their activity, recovery and sleep for better health. The Vire Clip sits discreetly at the waist – near the body’s core – and, together with the Vire app, turns signals from core temperature, breathing, and movement into clear timing guidance. Vire was founded in 2021 as a spin-off from Lappeenranta University research and is headquartered in Finland. Vire is going to market in 2026 and is currently raising its Seed round.We're seeking an Algorithm & Analytics Developer who enjoys turning complex and messy biosignal measurements into practical, user-facing features.
