Job Description
We are looking for a Full-Stack Engineer (m/f/d) for our portfolio company Jua.
Overview
Jua is working towards a universal physics simulator through a deep exploration of nature and the universe their interaction with humans business and the built environment. With a universal physics simulator we collapse that barrier and help to use natural resources efficiently and sustainably whilst increasing human standard of living and spurring economic growth.
By joining our talented multidisciplinary team youll help shape our culture of ambition transparent communication and rapid iteration. We offer exciting challenges creative freedom fair pay and generous stock options.
What were looking for
Were hiring a front-endleaning full-stack engineer (m/f/d) to help define and build the future of our platform.
You should have a strong sense of design deep empathy for users and a general grasp of machine learning or the latest AI technologies. You dont need to be a researcher or a math prodigy for this role but we are specifically looking for candidates who approach problems from first principles and thrive in a culture that grants significant individual responsibility. We value people who are deeply curious about how systems fundamentally work - whether its computers satellites AI societies or human psychology - and who are eager to collaborate with other exceptional individuals to broaden their perspective even further.
Youll thrive here if youre driven to push the boundaries of the current state-of-the-art and expand human knowledge in forecasting and simulating the future. If you believe that hard work leads to outsized returns enjoy taking ownership and building exceptional products and have a talent for transforming complex systems into clear fast and elegant experiences this is the place for you.
Jua is currently evolving its core platform into two focused products:
- A developer-focused API platform designed for integrators and quants to access our prediction models & data products for their daily trading operations. These users care about simple smart and clean interfaces low-latency data and seamless integration via our SDK.
- An AI-native product built for decision-makers like traders and meteorologists who want answers not just data. Think of a geospatial reasoning layer for planet earth. This product uses agents based on language models to interact with our simulation models to deliver insights and decision support.
Youll simplify complexity for non-technical users while enabling technical users to work with precision and control.
Location: Although we are a global team it is a requirement that applicants are currently based in Zurich Switzerland working on a Hybrid working model.
Our Tech Stack
- Frontend: TypeScript React & Tailwind
- Design: Ultra minimalistic lightweight design system. For some time now weve entirely skipped the classic WireframeFigmaComponent workflow and just vibe code most frontend components directly.
- Visualization: ECharts Mapbox Plotly Deck. gl for map-heavy and time-series UI
- Backend: Python FastAPI WebSockets gRPC endpoints little bit of rust Zarr & Clickhouse SQL db
- ML Interfaces: Real-time inference model metadata probabilistic forecasts & geospatial datasets
Tasks
- Own and shape full features and products end-to-end to support multiple products user personas and evolving data needs by building reusable UI components
- Build intuitive high-performance UIs for both technical users and decision-makers with a focus on clarity and responsiveness
- Develop rich interfaces for time-series geospatial and probabilistic data turning raw model outputs into decision-support tools
- Collaborate with researchers and engineers to make complex model outputs usable and understandable
Requirements
Need-to-have
- 4 years of front-end engineering with React and TypeScript
- Strong aesthetic sensibility and user-centered design mindset
- Proven ability to ship fast accessible maintainable UIs at a high-quality bar
- A desire to understand domain-specific workflows in energy weather or trading and use that knowledge to build better interfaces
- Exposure to data or ML APIs and eagerness to integrate model outputs into production UIs
- Familiarity connecting React front ends to Python backends (FastAPI WebSockets gRPC)
Nice-to-have
- Experience building products for expert users in domains such as energy trading quantitative finance or ML-ops
About you
- You take initiative and drive outcomes. You dont wait for direction. You identify challenges and opportunities take ownership and act decisively
- Youre pragmatic and resourceful. Youre deeply technical and think clearly under pressure but you prioritize progress over perfection. You work within constraints solve real problems and make smart trade-offs

- You obsess over the user. You care as much about the why as the how and you want to build tools people truly love to use
Benefits
- Own and ship fast. Work in a product culture where engineers drive decisions move from idea to production quickly and see their impact in days not quarters.
- Join a mission-driven company. Apply cutting-edge ML to global climate and energy challenges an impact-first alternative to profit-only tech or finance roles.
- Work on groundbreaking technology. Be at the forefront of weather forecasting and machine learning contributing to innovations that push boundaries.
- Collaborate in a high-agency team. Pair with experienced engineers and researchers in a hybrid environment that balances flexibility with in-person work.
- Shape a meaningful industry. Build solutions for the energy-trading sector using AI to drive real-world change and influence the future of global markets.
