Zusammenfassung

CarOnSale in Berlin is seeking a Flutter Engineer to own the field-ready vehicle inspection app from concept to production. You will ensure robust performance in real-world environments and work in a hybrid setup, collaborating with product, design and backend teams.

• Command of mobile fundamentals — performance optimization, offline-first architecture, security and accessibility
• Experience with CI/CD pipelines and agile delivery
• An AI-native way of working — you use tools like Claude, ChatGPT or Copilot actively in your development workflow and have real judgement about their limits
• English at C1 level — you communicate clearly across an international team
• Based in Berlin or ready to relocate

Aufgaben

• Collaborate with product managers and designers to shape architecture
• Mentor less experienced engineers and raise team standards
• Stay sharp on Flutter, Dart and mobile development trends and introduce valuable tools

Jobbeschreibung

Flutter Engineer — Vehicle Inspection (f/m/x) | Berlin

Most mobile roles give you a backlog. This one gives you an industry.

You build the app our inspection teams use in the field — the tool that kicks off every vehicle assessment, every dispatch decision, and every pricing call across 130,000 vehicles a year. You work in a team where coding agents write the first draft and your judgement decides what survives review.

Location: Berlin Schöneberg — hybrid, 3 days office / 2 days remote

About us

CarOnSale is the AI-powered operating system for B2B used car trading in Europe. Over 40,000 buyers from more than 20 countries trade on our platform — and 85% of inventory is exclusive to us. We connect software, pricing intelligence, logistics and financing in one layer — as the operating system for an entire industry.

One Platform. One Profit Engine.

What you'll own

• The vehicle inspection app — the mobile tool our inspection teams use in the field to assess, document and process vehicles. You own it end to end: design, build, maintain and improve it from concept to production
• Field-grade performance — our inspectors use this app in vehicle yards, on dealer forecourts, on weak connections. You profile, debug and optimise until it holds up in the real world, not just in the office
• AI-first development — coding agents, LLMs and AI-assisted development are part of the daily workflow here, not a pilot project. You decide where they accelerate the work and where they don't
• Technical bar — you set the standard for state management, networking, camera/media handling, offline-first architecture, and UI components. Your code is clean, testable and reviewed
• Architecture and direction — you shape technical decisions together with product managers, designers and backend engineers who own the broader inspection and logistics platform
• Team growth — you mentor less experienced engineers, review their work and raise the standard of the whole team
• Staying sharp — you track what moves in Flutter, Dart and mobile development and bring the tools worth adopting into the team

What you bring

• 3+ years of professional experience building production apps with Flutter and Dart
• Proven depth in complex mobile applications — state management, networking, API integration, camera/media handling, UI/UX components
• Command of mobile fundamentals — performance optimization, offline-first architecture, security and accessibility
• Experience with CI/CD pipelines and agile delivery
• An AI-native way of working — you use tools like Claude, ChatGPT or Copilot actively in your development workflow and have real judgement about their limits
• English at C1 level — you communicate clearly across an international team
• Based in Berlin or ready to relocate

Nice to have:

• Experience building apps used in field or operational environments (logistics, inspection, field service)
• Experience with camera integration, image processing, or document capture on mobile
• Automotive, marketplace or B2B platform background
• German at B2 level

What you can expect from us

• Hybrid working: 3 days office, 2 days remote
• 28 days annual leave
• 2× annual career & development conversations
• Company pension with 20% employer contribution
• Subsidised Deutschlandticket
• FitX or Urban Sports Club membership subsidy
• Structured onboarding with buddy programme and social events
• Lived diversity: active women's network, meditation & prayer room, dog-friendly office
