F2F Interview

One onsite interview and coding exercise as part of it.

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

• 10- 12 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.
