Brazil - Remote: Full Stack Developer (Python & React)

Job Duties

We are building a platform that merges real-time physics, structured knowledge, and autonomous intelligence. We are looking for developers ready to tackle one (or more) of those challenges:

• Complexity: Rendering massive tables and managing strict validation logic for mission-critical data pipelines.
• Interactivity: Building conversational UIs (streaming chat) and high-performance time-series dashboards that update in real-time.
• Visualization: Designing intuitive interfaces for Data Lineage, Knowledge Graphs, and Entity Mapping.

What You’ll Do

You will join a high-performance team, ensuring design consistency across the platform while focusing on one of the following distinct tracks:

Core Responsibilities

• Component Architecture: Create a reusable, strictly typed Angular component library that scales across AI, Dashboard, and Admin modules.
• Performance: Optimize change detection strategies and virtual scrolling to ensure the UI remains responsive and performant, whether rendering a live data stream or a 3D object.
• Data-Driven Design: Handle complex JSON schemas and heavy payloads, ensuring data precision from API to UI

Possible paths to work on the Project (you can contribute to one or more):

Data Platform & Management Tools

• Build Management Interfaces: Develop the "Control Room" for Data Engineers, including Data Catalog and Pipeline Configuration screens.
• Heuristics & Mapping: Create efficient workflows for "Entity Matching" that allow users to visually map raw sensor tags to physical assets.
• Visualizing Lineage: Implement DAG visualizations (D3.js or similar) to allow users to trace data asset layers and dependencies.

AI Interfaces & Visualization

• Build AI Assistant UI: Develop rich conversational interfaces that support streaming responses (SSE), markdown rendering, and interactive "artifacts".
• Advanced Dashboarding: Implement high-performance time-series charts using Plotly.js, ensuring smooth zooming/panning on large datasets.
•  Document Handling: Develop integrated viewers for PDF documents and rich media, allowing Agents to cite sources visually.

The Technology Stack

We use a modern, high-performance stack. You should be proficient in the Core and deeply knowledgeable in your chosen track.

• Programming Langage: Python and JavaScript
• Core Framework: React, TypeScript, RxJS.
• State Management: NgRx or Signals.
• Visualization: Plotly.js (Time-series), D3.js/DAGs (Lineage).
• API Integration: REST APIs (FastAPI), Server-Sent Events (SSE), WebSockets (using Socket.io)

Qualifications

Must Haves:

• Complete Bachelor's degree in Computer Science, Engineering, or related.
• 5+ years of experience in Back-end Development (Python focus).
• Strong proficiency in React and programming patterns.
• Experience building Admin Dashboards, B2B SaaS interfaces, or complex SPAs.
• Ability to handle complex API integrations and data modeling on the client side.
• Advanced English communication skills

Good to Have:

• Visualization: Hands-on experience with Plotly.js, D3.js, or Lineage/DAG graphs.
• AI/Chat: Experience building Chat/LLM interfaces and handling streaming text.
• Data Heavy: Familiarity with high-performance libraries and virtual scrolling.
• Media/Geo: Experience with PDF rendering in-browser or Map/GIS libraries (Leaflet, Mapbox).

Knowledge, Skills, and Abilities

• Component Architect: You write clean, decoupled components and understand how to build a UI kit that scales.
• UX Sensibility: You understand that a "Chat" interface needs to feel immediate and care about loading states and smooth transitions.
• You take pride in building tools that make other engineers productive, caring deeply about workflow efficiency and keyboard shortcuts.
