Description

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. 
  • 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/CERTIFICATION

  • Bachelor of Science - Computer Science

Education

Any Graduate
