Full Stack AI Engineer with Python - Mount Arlington, NJ - Contract Opportunity
Job Title: Full Stack AI Engineer with Python
Location: MUST be hybrid and onsite 2x weekly in Mount Arlington, NJ-Locals only
Duration: 6 months initial contract
Visa: USC, GC, EADs Only
Exp Level: 11+ years genuine candidates
Mode of Interview: 2 rounds interview with final ONSITE and coding exercise as part of it.
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.
ESSENTIAL DUTIES AND RESPONSIBILITIES
- Deliver features end-to-end on 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.
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.
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.
