Requirements

• Experience: 6+ years in software development with significant experience in complex Frontend architectures. • Stack Mastery: Deep proficiency in TypeScript and React. You understand how React works under the hood (reconciliation, rendering, performance). • Platform Mindset: Proven experience managing Monorepos (using tools like Nx, Turborepo, Lerna, or similar) and configuring build tools (Webpack, Rspack, ESBuild, Metro, Re.Pack). • Mobile & Desktop: Experience with React Native and/or Electron is highly critical for this role, as you will impact both platforms. • Architecture: Practical experience implementing Micro-frontends or modular architectures at scale. • CI/CD Ops: Familiarity with configuring pipelines (GitHub Actions, CircleCI) and optimizing build/test parallelization. • Soft Skills: You are empathetic to the struggles of other developers and have a "service-oriented" mindset toward internal teams. • Experience with native modules in React Native. • Experience in Web3 topics and technical stacks. • Active contributor to Open Source projects. • At Ledger, we are dedicated to continually investing in our employees which is why we offer more than just salaries; we provide comprehensive compensation packages that include a wide range of benefits. Here are some of the benefits you can look forward to: • Flexible work options - Our hybrid policy allows employees to work from home up to 3 times per week • Health & Wellness support - Health and Life Insurance. • Financial growth opportunities - Employees can become shareholders in Ledger as well as other financial benefits depending on your country of work. • Commuter allowance - Ledger offers a commuter allowance to contribute to your preferred means of transportation. • Learning & Development - A comprehensive suite of training solutions providing a personalised learning experience for every employee. • For regionally specific benefits, your Talent Acquisition contact will be able to provide you with more information. • We’re committed to building an inclusive hiring process. If you need any adjustments or accommodations, just let us know, we’ll do our best to support you.

Responsibilities

• Architecture & Monorepo Management: Set and uphold the engineering standards for our large-scale monorepo, Ledger Wallet. Drive improvements in dependency management, build performance, and structural organization so the codebase scales cleanly with dozens of contributors. • Micro-Frontends & Scalability: Work on shaping the technical strategy for decoupling our architecture by architecting automated CI/CD workflows and micro-frontend approaches that enable independent team deployments on both Mobile and Desktop Platforms. • Developer Experience (DX): Design and build internal tooling, scripts, and CLIs that remove friction for other developers. If a process is slow or manual, your job is to automate it. • Tech Stack Governance: Maintain the health of our core stack (React, React Native, Electron, TypeScript). Handle upgrades, minimize technical debt, and enforce best practices across the organization. • Mentorship & Advocacy: Act as a technical referent. Promote engineering standards, conduct high-level code reviews.

Benefits

• Insurance benefits often accompany PTO and equity compensation packages but aren't mentioned explicitly within this text snippet. • Remote work options may be available at Ledger but aren't specifically stated within this portion of the text; however, it is common for tech companies to offer such flexibility and might exist elsewhere in their full benefits package documentation.
