Senior Software Engineer

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.

• Minimum bachelors degree in Computer Science, Computer Engineering, or other job-related field.
• 5+ years of experience building and operating production backend services in a cloud environment.
• Strong TypeScript/Node.js skills; hands-on experience with NestJS or an equivalent structured backend framework.
• Solid understanding of relational databases and ORM-driven migrations (Prisma or similar).
• Familiarity with containerization (Docker) and deploying services to Kubernetes via Helm.
• Experience working in a GitOps or CI/CD-driven delivery model (GitLab CI, ArgoCD, or similar).
• Ability to read and write SQL against analytical engines (Trino, Athena, Presto, or similar).
• Strong API design instincts - REST, versioning, Swagger/OpenAPI documentation, and consumer-first thinking.
• Strong knowledge of OO design and industry best practices for software development.
• Excellent communication and collaboration skills across engineering disciplines.
• Detail-oriented, self-motivated, and able to work independently in a fast-paced, dynamic environment.
• Preferred: experience with observability tooling - Grafana dashboards, Prometheus metrics, structured logging (Pino, etc.).
• Preferred: familiarity with AWS data services: S3, Glue, Lake Formation, or Iceberg table format.
• Preferred: comfort reading and writing Helm chart templates and values files.
• Preferred: A bias toward automation, clean abstractions, and keeping operational complexity low.

What We´ll Offer

• 22 days of PTO with the possibility to carry over 10 days to the following year.
• Company Holidays, plus your Birthday off!
• Company-sponsored benefit plans, including medical, dental, and vision insurance plus life, STD, and LTD coverage, and 401(k).
• Flexible work schedule
• And more to come!

Why Now?

This is an exciting time to be at Universal DX. We are growing rapidly and starting our US operations by building up our team, starting our lab and business operations, and establishing strategic partnerships.

We are looking for passionate changemakers to be a part of our journey in this expansive time for us.

Universal DX, Inc. is an international Company with a highly experienced team focused on cracking cancer’s code. Through our multi-omics and bioinformatics models, we have figured out how to read the disease’s signals in blood with high accuracy to detect cancer in its earliest stages. Starting with a colorectal cancer screening liquid biopsy test, we are building a multi-cancer platform that can identify the unique DNA regions associated with different types of cancers.
