Overview

We are building an internal sustainability data-driven application and are looking for a Full-Stack Developer with strong frontend expertise and solid backend/data integration skills.

You will primarily focus on building a polished, production-quality frontend while integrating with Python-based backend services and Databricks-powered data pipelines.


What You’ll Work On

  • A full-featured internal product UI (not just dashboards)
  • Backend services that connect frontend ↔ data pipelines
  • Integration with Databricks workflows (batch data processing, GB-scale datasets)


Responsibilities

  • Develop a modern, scalable frontend application (likely React or similar)
  • Implement backend APIs using Python (FastAPI, Flask, or similar)
  • Integrate frontend with data processed via Databricks pipelines
  • Collaborate with the team to implement existing architecture (not design from scratch)
  • Ensure smooth data flow between UI and backend services
  • Write clean, maintainable, and well-tested code


Required Skills

  • Strong frontend experience (React, Vue, or similar frameworks)
  • Solid JavaScript/TypeScript skills
  • Experience building product-grade UIs (not just simple dashboards)
  • Python backend development (FastAPI, Flask, or Django)
  • Experience consuming and building REST APIs
  • Basic understanding of data pipelines and ETL workflows
  • Strong Excel and VBA proficiency, including deciphering complex spreadsheet models and reprogramming their functionality into robust Python-based applications.
  • Comfortable working in a team and executing defined tasks


Nice to Have

  • Experience integrating with Databricks or Apache Spark environments
  • Understanding sustainability or ESG Data
  • Familiarity with data-heavy applications
  • Experience with authentication, state management, and performance optimization
  • Exposure to cloud environments (AWS, Azure, or GCP)
