About the role
Full Stack Engineer
6 months initial contract
2 days per week onsite Mount Arlington, NJ
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 SUMMARY
EngagePro 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 RESPONSIBILITIES
Deliver 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 QUALIFICATIONS
The Build & Test Mandate:
This 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' EXPERIENCE
4–7 years full-stack engineering on production SaaS.
TECHNOLOGY/SOFTWARE KNOWLEDGE
Strong 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 TRAVEL
10%
PHYSICAL REQUIREMENTS
Exerting 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.
