Build and maintain high-performance TypeScript backend services and event-driven infrastructure. Design scalable APIs, integrate PostgreSQL/MySQL, AWS SQS, and Centrifugo, ensure reliability, security, and observability, optimize production systems, modernize legacy code, and own end-to-end feature delivery with strong testing, debugging, and performance tuning.
Sequencing is building the interface between humanity and its DNA.
Using clinical-grade whole genome sequencing, AI, and a rapidly expanding ecosystem of genomic applications, we help people better understand themselves, their health, and their future through their DNA.
The human genome is one of the most valuable and underutilized resources in the world. Our mission is to transform the human genome into a lifelong source of personalized guidance and build the trusted home for every genome on Earth.
As the world’s largest direct-to-consumer whole genome sequencing platform, Sequencing is helping define the future of AI-powered personalized health.
We’re a profitable, venture-backed, fully remote company building category-defining products that help people better understand themselves through their DNA.
