Fullstack Developer - Frontend Focus

Fluxion is at a rare stage where the hardest problems are still unsolved — and your decisions will shape how the product, technology, and culture evolve

Help us turn complex models into intuitive, powerful user experiences

As a Fullstack Developer with a frontend bias, you’ll focus on building Fluxion’s grid + graph UI — where users interact with models, scenarios, and AI-assisted workflows. You’ll work closely with design and backend to make deeply technical concepts feel clear, responsive, and even enjoyable.

You’ll still contribute across the stack, but your strength is in translating complexity into great interaction.

What you’ll do

  • Build rich, interactive frontend features for modelling, scenario planning, and analysis

  • Collaborate closely with product design to refine UX and interaction patterns

  • Integrate AI-powered workflows into user-facing features

  • Work end-to-end: from APIs and state management to polished UI

  • Help shape frontend architecture, performance, and developer experience

About you

  • Strong frontend experience (React or similar) with solid fullstack fundamentals

  • Experience building complex and data-heavy UIs

  • Product-minded: you care about usability, clarity, and real user outcomes

  • Comfortable working in an early-stage, fast-moving environment

About Fluxion

Fluxion is a decision intelligence platform that empowers forward-looking teams to answer their toughest “what-if” questions with confidence. Using AI-native scenario modeling, Fluxion lets organizations explore assumptions and simulate outcomes across financial and operational models in real time — without rebuilding spreadsheets or rigid tools. Its semantic approach to decision modeling keeps assumptions explicit, preserves causality, and delivers traceable, explainable insights so teams make better decisions faster. Designed for high-impact decisions under uncertainty, Fluxion replaces fragile, manual exploration with a dynamic environment where curiosity is cheap, safe, and continuous.
