## About the role

At Prenuvo , we are on a mission to flip the paradigm from reactive “sick-care” to proactive health care. Our award-winning whole body scan is fast (under 1 hour), safe (MRI has no ionizing radiation), and non-invasive (no contrast). Our unique integrated stack of optimized hardware, software, and increasingly AI, coupled with the patient-centric experience across our domestic and global clinics, have allowed us to lead the change against “we caught it too late again".

- Design and maintain APIs supporting checkout, payments, scheduling, customer accounts, and order management
- Integrate with third-party platforms including Stripe , CommerceTools , Salesforce , Voucherify , and other business-critical systems
- Design resilient distributed systems with robust error handling, observability, and monitoring using Datadog
- Optimize application performance, database queries, and service reliability for high-volume transactional workloads
- Write comprehensive automated tests and contribute to a strong engineering culture focused on quality and reliability
