## Description

Universal DX is seeking an experienced Senior Software Engineer to join our growing team. You will be a key technical contributor building and scaling the backend services and data APIs that power our observability and analytics platform. You will own features end-to-end, from API design through deployment on Kubernetes, and collaborate closely with SREs, data engineers, and product stakeholders.

You will be part of a team that is passionate about developing novel diagnostic tests for the early detection of cancers. As part of the team, you will be in a Company that aims more than to become one of the leaders in the industry. We want to have a huge positive impact on society by achieving the ambitious purpose of "making cancer a curable disease by detecting it earlier"

How You'll Contribute

 * Design, build, and maintain production-grade NestJS APIs and backend services that serve internal and external consumers.
 * Own the full lifecycle of a service: schema design, business logic, observability instrumentation, Helm chart configuration, and GitOps deployment.
 * Write and manage database migrations using Prisma; ensure schema changes are safe for zero-downtime deployments.
 * Implement health endpoints, SLIs, and structured logging patterns that give the SRE team the signals they need.
 * Collaborate with data engineers to build APIs over Trino and data lake sources (S3/Glue/Iceberg), translating complex analytical queries into reliable, performant endpoints.
 * Write and maintain unit, integration, and end-to-end tests; treat CI green as a hard gate before merge.
 * Participate in code reviews, architectural discussions, and incident postmortems as a domain expert.
 * Mentor and coach junior engineers on NestJS patterns, API design, and service ownership.
