Full Stack Developer

Overview

Job Purpose

ICE Data Services (an Intercontinental Exchange company) is seeking a mid-level full-stack developer to join its Data Impact & Innovation team. This team supports a variety of reference data, index, climate finance, and alternative data products. This role presents a unique opportunity to support and enhance big data applications and products aimed at helping the financial sector understand and respond to carbon transition risk, physical risk, and related challenges.

Responsibilities

• Develop and enhance web-based UI applications around the ICE Climate datasets:

• Use modern front-end frameworks for building crisp and clear visualizations

• Design and implement data modeling and transformation sufficient to support API endpoints for front-end visualizations

• Hands-on execution of all stages of the development lifecycle, from rapid prototyping, to iterative refinement based on user feedback, to testing remediation and release.

• Support integration and enhancement of existing web applications that allow coherent exploration and analysis of multiple climate datasets and methodologies across different financial asset classes

• Design and implement client-side strategies for rendering large geospatial and tabular datasets at scale, including appropriate use of tiling, virtualization, caching, and data-reduction techniques

• Lead efforts to design, architect, and implement software components with minimal oversight.

• Independently handle project activities related to builds and deployments.

• Write and maintain automated tests, including end-to-end testing with tools like Playwright, to verify the functionality and quality of the software.

• Effectively leverage AI and LLM-based developer tooling to accelerate development workflows and improve code quality.

• Identify opportunities to improve and optimize applications.

• Work with business analysts and product management to understand and refine new requirements.

Knowledge and Experience

• 3+ years of professional experience and demonstrated ability in most of the following areas:

• JavaScript technologies such as React and TypeScript

• Node.js backend frameworks, particularly NestJS

• Python web backend frameworks, particularly FastAPI

• Relational databases and SQL, with comfort reading and writing analytical queries against cloud data warehouses (e.g. Google BigQuery)

• Core knowledge of fundamental web protocols and standards (HTML5, WebSockets, CORS, cookies and session management, etc.)

• Cloud computing and infrastructure, especially Google Cloud Platform

• Client-side mapping using Mapbox GL JS, including working with vector tiles, GeoJSON, and custom source/layer/style configuration

• Spatial data in relational databases, particularly PostGIS, including spatial indexes and SQL-level geometric operations

• Demonstrated ability to optimize web applications for performant client-side rendering of large datasets — familiarity with strategies such as vector tiles, virtualization, web workers, data decimation, client-side caching (IndexedDB), React performance profiling, and GPU-accelerated rendering

• Automated testing frameworks, particularly end-to-end browser testing (e.g. Playwright)

• Practical experience using AI/LLM coding assistants and a demonstrated ability to integrate them productively into development workflows

• Excellent written and verbal communication skills, in order to collaborate effectively with in-person and remote technical colleagues, business stakeholders, and client end-users to brainstorm tradeoffs and timelines.
