We're looking for a Full Stack Software Engineer to join an ambitious project at the intersection of scientific computing, causal AI, and collaborative software.
You'll help build a next-generation platform that enables scientists and engineers to collaboratively create, validate, and simulate causal probabilistic models in real time. Think of a real-time collaborative workspace for advanced scientific modeling, where users can ingest data, fit models, run counterfactual simulations, and visualize results through an intuitive interface.
This role requires someone who enjoys solving complex technical problems, working across the full stack, and collaborating with a highly technical research team while maintaining a high degree of autonomy.

What You'll Do
Design and build new product capabilities across both frontend and backend.
Integrate existing Python scientific libraries into a production web application.
Develop features for data ingestion, processing, storage, and visualization.
Build interfaces for model validation, prediction analysis, and performance metrics.




Implement automated model fitting workflows.
Develop user experiences for running and visualizing causal and counterfactual ("what-if") simulations.
Improve real-time collaborative functionality across the application.
Work closely with researchers to transform advanced modeling capabilities into intuitive product features.

What We're Looking For

The adecuado candidate will have the following profile:
Degree in Computer Science, Engineering, or related field.
5+ years of professional software engineering experience.
Strong experience with React and TypeScript, including modern tooling (Vite, pnpm) and client-side routing.
Solid Python development experience, ideally with FastAPI and Pydantic.
Experience designing and consuming REST APIs.
Comfort with modern state and data-fetching patterns (TanStack Query, Jotai, Redux, or equivalents).
Experience with component libraries and utility-first CSS (MUI, Tai
