Senior Frontend Engineer (React / TypeScript).

Job Description

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

Qualifications

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
