Front-End Engineer

We seek a Front-End Engineer to lead the architectural evolution of our Terminal UI. You will design the core systems, specifically our shared component libraries and data visualization layers, that power our platform.

Your main goal is to build a frontend architecture that supports rapid, AI-assisted development. You will define the design patterns, strong typing contracts and component abstractions that allow the wider engineering team to ship features quickly without compromising the architecture. By creating a robust, modular foundation you will ensure our codebase remains scalable and coherent, and you will act as the technical authority for our Next.js and TypeScript environment., * Architectural Strategy: Lead the technical direction for our frontend monorepo. You will decide on state management, routing and module boundaries within Next.js and TypeScript to ensure long-term scalability and ease of maintenance.

• Component System Architecture: Design and develop our internal UI library (based on MUI). You will build reusable, strictly typed component abstractions that serve as the building blocks for the engineering team and AI agents.
• Performance Engineering: Build and improve high-performance, low-latency user interfaces. You will profile application performance, minimize re-renders and ensure the platform remains responsive under heavy data loads.
• Code Governance and Quality: Set the architectural patterns and coding standards that govern our development. You will review complex technical proposals and provide the oversight needed to ensure that high-volume contributions, including those from AI agents, adhere to robust engineering principles.
• Technical Leadership: Act as the primary expert for frontend technologies. You will guide the engineering team on UI best practices and help them use AI tools effectively while maintaining a clean and cohesive codebase.

Do you have experience in UI?, Do you have a Master's degree?, * Bachelor's/Master's degree in Information Technology, Computer Science, or equivalent experience.

• 3+ years of professional experience in Frontend Development.
• Strong proficiency in TypeScript, React, and modern JavaScript.
• Excellent problem-solving abilities and capacity to work autonomously and adapt to a flexible, evolving environment.
• Required experience:

• Hands-on experience with Next.js
• Experience with Material UI (MUI) or similar component libraries.
• Strong eye for design (UI/UX): Ability to build polished, aesthetically pleasing interfaces and bridge the gap between design and engineering.
• Solid understanding of testing principles and experience with frameworks like Jest and Cypress or Playwright.

• Familiarity with Monorepo structures and tools (e.g., Turborepo, Yarn Workspaces).
• Proficient with Git, Docker, and CI/CD workflows.

• Hybrid Work Environment: This role is hybrid, with time split between working from home and our London office, with in-office days from Tuesday through Thursday.
• Compensation & Benefits: Modo Energy offers a competitive salary along with a comprehensive benefits package, including private top-tier healthcare and dental coverage with Bupa, a pension scheme with employer contribution, 25 days of annual leave (excluding bank holidays), 5 flexible days to be taken on a Monday or Friday, and a day off for your birthday.
