Job Description

We're hiring a hands-on Full Stack Engineer to join an onsite Agile team in New York on a contract basis, with potential to extend. You'll build and ship end-to-end applications across the stack, from responsive React interfaces to Python backend services, scalable REST APIs, and analytics-ready data models that support product features, reporting, and business insight.

This role also includes building and maintaining real-time data pipelines with Apache Kafka, working with event-driven and microservices patterns, and handling asynchronous processing and messaging. You'll be expected to improve performance, scalability, reliability, and data quality across services.

The right person brings strong system design judgment, production experience with Python frameworks such as FastAPI, Flask, or Django, deep API design and versioning experience, solid SQL and relational database skills, and experience working in Git-based Agile/Scrum environments using Jira. Helpful extras include exposure to TypeScript, Docker, Kubernetes, AWS, Kafka Streams, schema registries, Grafana, and security practices such as OAuth and JWT.
