Senior Frontend Engineer (React / TypeScript)

About Routescanner Routescanner is the world's leading container logistics intelligence platform, helping shippers, freight forwarders, and cargo owners discover, compare, and optimize intermodal container routes based on transit times, carrier reliability, and CO₂ emissions. Our platform connects thousands of logistics professionals with actionable, real-time routing data — making global supply chains more efficient, resilient, and sustainable. We're growing fast, and we're looking for a senior frontend engineer who doesn't need hand-holding to thrive. What You'll Work On 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

What We're Looking For Must-haves: 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

Strong plus: Experience with geospatial or data-heavy UIs (maps, charts, large tables)

Familiarity with observability and error tracking tools (Sentry, PostHog)

Background in logistics, supply chain, or B2B SaaS products

Experience with design systems and component libraries

Familiarity with testing (Vitest, Playwright, or similar)

Familiarity with AI-assisted development tools

How We Work Small team, high trust — no micromanagement, no approval chains for every decision

GitHub-centric workflow — PRs, reviews, and automated pipelines keep quality high without bureaucracy

Observability-first — we monitor, alert, and fix things before users notice

Clean code culture — we refactor, we review, we don't let tech debt compound silently

AWS-native infrastructure — you'll deploy to a well-maintained cloud environment without fighting DevOps

What We Offer 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
