React Developer / Engineer — New York, NY

Job Description

Must Have Technical/Functional Skills

Key Skillset Summary

• React proficiency demonstrated through clear, well-built professional experience.

• TypeScript or strong JavaScript fundamentals with a clear understanding of type safety and why it matters in a team codebase

• Python proficiency: able to write backend services, REST APIs, and data manipulation scripts without significant support

• SQL working knowledge: able to query, filter, join, and aggregate data independently — including window functions and CTEs

• Ability to read a wireframe and translate it into working front-end code with attention to detail and interaction fidelity

• Clear communicator: able to ask for what you need, flag blockers early, and explain a technical decision in plain terms

Tech Stack: Core Front-End

• React: components, hooks, props, state — able to build from scratch without a tutorial open

• TypeScript / JavaScript: type annotations, async patterns, browser fundamentals

• CSS: layout, responsive design, basic animation — comfort translating a design into code

• Testing: unit tests with Jest or equivalent; understanding of why tests exist, not just how to write them

Design & Prototyping

• Figma: able to read and navigate design files; bonus if you have created or annotated them

• Streamlit: rapid prototyping of data-backed surfaces and internal tooling

• Storybook: component documentation and isolated development (familiarity sufficient)

Backend & Data

• Python: FastAPI, Flask, or equivalent for building REST APIs and backend services

• SQL: SELECT, JOIN, GROUP BY, window functions, subqueries — comfortable querying a data warehouse independently

• REST API design: data contracts, request/response handling, error patterns

• Basic data pipeline awareness: able to read and understand how data flows from source to surface

Tooling & Environment

• Git: branching, pull requests, code review workflow in a team environment

• Cloud familiarity: GCP, AWS, or Azure

• CI/CD basics: able to run tests, read a build pipeline, and understand deployment concepts

Nice To Have Skills

• Familiarity with Figma: able to open a design file, understand layout and component structure, and identify what has changed between versions

• Streamlit experience: built an internal tool, data app, or prototype for a class project or personal use

• Storybook or component documentation experience

• Mulesfot, FastAPI, Flask, or equivalent: built and deployed a backend service, even in a class or personal project context

• Experience with cloud platforms: GCP, AWS, or Azure — even at a student or free-tier level

• Exposure to databases beyond SQL: document stores, key-value stores, or basic data warehouse concepts

• Exposure to design systems, component libraries, or any structured approach to front-end consistency

Roles & Responsibilities

UI Development with full stack foundation

• Full-Stack Feature Ownership

• Work seamlessly across the entire technology stack with a primary focus on React on the front end while managing Python-based backend services, APIs, and data integrations.

• Own the entire lifecycle of what you ship across the full surface area of your work.

• Build frontend interfaces, write corresponding backend endpoints, and collaborate closely with data scientists to understand and render model outputs.

• Harden, orchestrate, and convert agentic output into enterprise-grade UI applications optimized for maximum security, usability, and performance.

• Functional Prototyping

• Develop working, functional prototypes using real, interactive code rather than static, click-through designs.

• Iterate rapidly to enable the team and end-users to interact with features early, allowing for quick directional shifts.

• Prioritize speed to close the gap between design and functionality, validating features quickly before committing to full-fidelity production.

• Component Library Contribution

• Contribute reusable components to a shared library that powers the entire portfolio of intelligence products.

• Learn, apply, and maintain strict design and coding conventions across the shared library.

• Document your work thoroughly and write robust tests to ensure all shared components are safe and stable for reuse.

• Cultivate a strong architectural sense of what features belong in a shared library versus what should remain product-specific.

• Design Collaboration

• Partner directly with designers to read wireframes precisely, ask critical questions early, and identify implementation constraints before they lead to rework.

• Actively participate in design reviews, user feedback sessions, and strategic product decisions.

• Formulate, maintain, and clearly communicate a strong, informed point of view on product design and user experience.

• Backend Services & Data Integration

• Build and maintain the backend services and API layers that connect data pipelines, scoring models, and structured data assets to front-end surfaces.

• Write robust endpoints, define and manage clear data contracts, and proactively handle complex edge cases to elevate prototypes to dependable, field-ready systems.

• Collaborate closely with data scientists and platform engineers to comprehend data structures and guarantee accurate frontend presentation.
