Frontend Engineer (KoTerminal)

The energy transition is the biggest infrastructure buildout in human history. Modo Energy is the data platform at the centre of it.

We build the benchmarking forecasting and valuation tools that the worlds most serious energy investors developers and operators depend on to make decisions. If a battery gets financed built or traded anywhere in the world theres a good chance Modo data was in the room.

Founded in 2019 were 80 people across London New York Sydney and Madrid; $30M Series B AI-native and moving fast.

This is a rare chance to join a category-defining company at the moment its scaling globally.

Modo Energys engineering team builds the systems behind the Modo Terminal the data research and agentic platform that energy market professionals rely on every day. Were growing fast and our ambitions are growing faster: from a data and research product to an agentic layer that lets users work with our domain knowledge through natural language and AI-assisted tools.

Were hiring frontend engineers to join one of our product teams: Terminal Data Ko (our AI Analyst) or Modelling. Each team owns a business capability end-to-end including its own frontend backend and infrastructure and every team ships to production independently without centralized approval. Wherever you land youll help shape a shared TypeScript React and codebase in a monorepo built for rapid AI-assisted development and youll build against a company-wide design system so what you ship stays consistent with the rest of the product.

Were looking for engineers who learn fast and go wide. You wont be boxed into pixel-pushing; the best people on our teams move fluidly between component architecture performance work and the backend or infrastructure basics behind the features they build. If youre the kind of engineer who picks up a new tool library or part of the stack without needing much of a runway this is built for you.

• Help shape the technical direction of our frontend monorepo so it scales with the team and the product.
• Design and build components in our internal UI library built on MUI that the rest of the team can build on.
• Build and improve high-performance low-latency interfaces that hold up under real live market data.
• Write well-tested code (Jest Cypress or Playwright) and contribute to how the team reviews and documents its work.
• Split your time between shipping new features and keeping things healthy: maintenance performance and production issues are a normal expected part of the job not an interruption to it.
• Work directly with design and with the people who understand the domain (energy analysts data scientists) to bridge the gap between design and engineering.
• Cross into the backend and infrastructure basics behind your own features when the team needs it: an API change a deployment fix a bit of the pipeline behind the data youre rendering.

The Essentials

• 3 years of professional frontend development experience with excellent TypeScript React and .
• Experience with MUI or a similar component library.
• Solid testing practice with frameworks like Jest and Cypress or Playwright.
• Proficient with Git Docker and CI/CD workflows and familiar with monorepo structures and tools (Turborepo Yarn Workspaces or similar).
• Fluent with AI-assisted development tools (Cursor Claude Code GitHub Copilot or similar). We write a lot of code this way.
• An eye for design (UI/UX): you can build polished aesthetically pleasing interfaces not just functional ones.
• A fast learner with good judgement comfortable making calls on component design and whats good enough to ship and genuinely energized by picking up unfamiliar tools stacks or problem areas rather than staying in one lane.
• Comfortable in a small fast-moving team where youre expected to figure things out make trade-offs and ship with real autonomy over how.

Nice to have

• Start-up or scale-up experience.
• Familiarity with Python.
• Experience with energy markets.
