Full Stack Engineer

Full Stack Engineer (Contract)

Engineering | Contract with opportunity for extension | New York, NY | Onsite

About the Role

We are partnering with a global consulting firm to bring on a Full Stack Engineer who can build end to end. You will join a cross-functional Agile team designing and shipping scalable applications, real-time data pipelines, and the user interfaces that sit on top of them. The team works at the intersection of engineering and business, so the data you wire up directly powers product features, reporting, and strategic insight.

This is a hands-on builder seat. You will design systems, write the code, and own performance and reliability across the stack. Strong system design instincts and a bias toward clean data are what set apart the people who do well here.

What You Will Own

• Build responsive front-end interfaces in React, including hooks, component lifecycle, and state management.
• Design and maintain backend services in Python (FastAPI, Flask, or Django).
• Stand up and maintain real-time data pipelines using Apache Kafka.
• Design and version RESTful APIs that scale.
• Partner with backend engineers, frontend engineers, product managers, and analysts to shape analytics-ready data models that drive product and reporting.
• Implement event-driven and microservices patterns, including async processing and messaging.
• Tune performance and scalability across services.
• Work in a Git-based workflow, document what you build, and bring ownership to data quality and reliability.
