Senior Frontend Engineer (React / TypeScript)

Routescanner is the world's leading container logistics intelligence platform, helping shippers, freight forwarders, and cargo owners optimize intermodal container routes. They are looking for a senior frontend engineer to build and maintain a React/TypeScript frontend at scale, own complex UI components, and work closely with backend engineers on API contracts.

• Build and maintain a React / TypeScript frontend at real scale
• Own complex UI components: route search, filtering, map-based visualization, data tables, and comparison views
• Work closely with backend engineers on API contracts (REST / BFF patterns)
• Integrate third-party tools including Auth0, PostHog, Sentry, and mapping/routing engines
• Maintain high performance standards — lazy loading, code splitting, bundle optimization
• Leverage AI-assisted development tools (Claude) as part of your daily workflow
• Ship via GitHub Actions CI/CD pipelines
• Participate in architecture and UX decisions — your opinion will carry weight

• 5+ years of professional frontend development with React and TypeScript
• Fluent in Polish and English
• Strong understanding of component architecture, state management, and frontend performance
• Experience working with REST APIs and designing frontend data flows
• Solid command of modern CSS and responsive design
• Experience with CI/CD pipelines and Git-based workflows
• Clean code as a practice — you write components your colleagues can confidently extend
• Genuine ability to self-direct: you can take a loosely defined problem, break it down, and deliver
• Experience with geospatial or data-heavy UIs (maps, charts, large tables) [strong plus]
• Familiarity with observability and error tracking tools (Sentry, PostHog) [strong plus]
• Background in logistics, supply chain, or B2B SaaS products [strong plus]
• Experience with design systems and component libraries [strong plus]
• Familiarity with testing (Vitest, Playwright, or similar) [strong plus]
• Familiarity with AI-assisted development tools [strong plus]

• Competitive salary benchmarked to your market
• Remote-friendly setup (we care about output, not location)
• Direct impact on a product used by global logistics professionals every day
• Work in a genuinely interesting domain — intermodal routing is hard, and the problems are real
• A lean, senior team where your frontend decisions actually ship
• AI tooling as a first-class part of the workflow — not an afterthought
