QA & Reliability Engineer

About Ucardia

Ucardia is redefining longevity and vitality. We combine credentialed coaches, connected devices, and AI-powered insights to deliver personalized, scalable programs that help people optimize cardiovascular and metabolic health—extending healthspan and improving quality of life.

Headquartered in Dallas, Texas, we partner with forward-thinking medical practices, concierge providers, and employers who want to differentiate their offerings, improve outcomes, and elevate the care experience through a modern, tech-enabled platform that integrates directly into care delivery.

Reporting to the Director of Product Strategy & Operations, you’ll play a foundational role in defining how quality is evaluated, prioritized, and upheld across our mobile apps, backend systems, data pipelines, and dashboards.

We’re looking for someone with senior judgment and strong instincts —someone who can spot risk early, bring clarity to ambiguity, and help the team build confidence in what we ship. The contract structure allows both sides to validate fit, with the expectation that this role can evolve into a long‑term, full‑time position as the company grows.

If you’ve helped a product mature from “it works” to “we trust this in production,” this role was built for you.
