Senior Full-Stack Developer (React Native)

About Us

Eli is the women's health company making continuous hormone monitoring possible. We empower people to understand their bodies every day and improve their health outcomes across their lives. Hormones are at the core of our health, yet they remain a black box. Eli is on a mission to unlock this box by developing a product that provides real-time and lifelong insights from saliva.

We are a diverse, intentional, and fast-moving team driven by our mission. You will work with a small group of experienced engineers, scientists, and entrepreneurs who are shaping the future of at-home testing by developing and commercializing new technology. Eli is a venture-backed and early-stage startup. You can visit our website or check out recent press articles to learn more about us.

About The Role

• The Bigger Picture:
• Work directly with our CTO, marketing team and data scientists to deliver new features. You'll be part of a team that's not afraid to push boundaries and adopt the latest technologies.
• Dive into infrastructure, security, auditing, monitoring, logging, analytics, and KPIs. We have a robust DevOps infrastructure, but we love developers who want to understand the full stack.
  

About You

• Health-Conscious: You understand the value of technology that improves human well-being.
