Looking for a mid to senior level person, level II-III in a contract capacity that would be approximately 6 months long to help build and test capacity.Position SummaryEngagePro is MedPro's Healthcare Provider (HCP) engagement platform – a net-new, AI-first product built out of MedPro Labs and is now hardening toward a production launch. This role adds dedicated build capacity to accelerate that launch, with test engineering as an equal half of the mandate.Essential Duties And ResponsibilitiesDeliver features end-to-end on EngagePro's modern, AI-first stack: Reacj front end, FastAPI services, PostgreSQL and MongoDB persistence.Build the automated test foundation for launching product – unit, API, integration, and end-to-end coverage that lets the team ship quickly and safely.Contribute to AI-in-product integration patterns as a core part of EngagePro's value.Job QualificationsThe Build & Test MandateThis role is explicitly hybrid: a functional full-stack engineer who is also a strong test engineer.You write the feature and the automated coverage that proves it.On a launching product, test quality is what makes velocity safe.Working Model (Contract)Per MedPro's support model, contractors do not hold production access. Deployments and production operations pair through the full-time pod lead; your job is to make that pairing cheap — clean pipelines, feature flags, strong observability, and changes that are safe to ship.AI-assisted development is the standard working mode.A focused 6-month engagement aligned to the launch window, with extension evaluated against launch progress.Years' Experience4–7 years full-stack engineering on production SaaS.Technology/Software KnowledgeStrong on the modern stack: React and Python/FastAPI with PostgreSQL; MongoDB a plus.Genuine test-engineering depth: pytest, Playwright, API and integration testing, and test design — not incidental coverage. This is a stated, weighted requirement for this role.Fluency in AI-assisted development required: experience launching a net-new SaaS product and life-sciences exposure both preferred.Required Travel10%Physical RequirementsExerting up to 10 pounds of force occasionally and/or negligible amount of force frequently or constantly to lift, carry, push, pull or otherwise move objects, including the human body.The individual is required to have close visual acuity to perform an activity such as preparing and analyzing data and figures; transcribing; viewing a computer screen and extensive reading.The individual in this position needs to occasionally move about inside the office to access file cabinets, office machinery, etc.The individual must be able to remain in a stationary position 70% of the time.Education/CertificationBachelor of Science - Computer Science
