About the Role

Job Title: Full-Stack Engineer (Front-end focus)
Employment Type: Full-time
Department: Engineering

Responsibilities and 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.

Required Qualifications

• 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 Qualifications

• 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 don't wait for direction. You identify challenges and opportunities, take ownership, and act decisively.
• You’re pragmatic and resourceful. You're deeply technical and think clearly under pressure, but you prioritize progress over perfection.
• You thrive in fast-moving, early-stage environments. You’re energized by rapid iteration and ambiguity.
• 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.
