Web Developer / Software developer (part time)

CHo Nova is digitalizing chocolate manufacturing.

Using proprietary ultrasound-based sensing, we enable manufacturers see what is happening inside their production process in real time and turn that data into cost savings, productivity gains and quality optimization.

Already deployed across multiple brands in 5 countries, we are scaling our decision-support platform: it consolidates sensor, process and product data, flags deviations before they become defects, and — as our physics-guided ML roadmap matures — recommends what to change and why.

Tasks

Your mission is to architect and build the next generation of our customer-facing web application on a modern, professional stack (React + Type Script), turning rich production data into an interface a plant manager understands at a glance.

• What You’ll Do
• Architect and build a web app frontend, replacing our Streamlit framework with a robust, maintainable React + Type Script application
• Create interactive dashboards for real-time data: production monitoring with traffic-light indicators, control charts, reference envelopes with confidence bands, zone-resolved run summaries, and trend views.
• Make statistics intuitive — our platform surfaces statistically rigorous outputs (SPC, repeatability, confidence intervals); your job is to make them readable without a statistics degree.
• Integrate with our Fast API back-end and time-series data layer, and implement backend features yourself when needed.
• Own quality and shipping: CI/CD for the frontend, tested releases, documentation, staging/production discipline.

Requirements

• Demonstrable experience building real web apps — show us your portfolio: React + Type Script in production, or serious personal/academic projects.
• Strong data-visualization skills (Plotly, Recharts, D3 or similar), ideally with time-series or scientific data.
• An eye for UI/UX: you can derive a coherent design system from an existing brand identity and apply it consistently across an application.
• Ability to ship independently and take ownership of an entire surface area.
• Python / Fast API proficiency — you can implement backend features when needed.

Nice to have

• Understanding of CI/CD for frontend applications.
• Interest in scientific, industrial or data-heavy applications.
• Experience with authentication, role-based access, or multi-tenant Saa S.
• Exposure to manufacturing, Io T or sensor-data products.

Benefits

• Real impact. Your dashboards run on the factory floors of leading chocolate brands from day one.
• End-to-end ownership. You own the customer-facing frontend.
• Deep tech, tangible product. Physics, ultrasound, statistics and machine learning — applied to making better chocolate.
