Every SIXT booking ends here. The Orange Checkout team owns the final, most critical step of the customer journey — the moment a browsing session turns into revenue. You'll be working on a product that's constantly evolving — one week you're optimizing conversion on a new payment flow, the next you're rebuilding a step to support a market launch. If you like solving problems where the ground keeps shifting under you (in a good way), this is that kind of team.

YOUR ROLE AT SIXT

You turn ambiguous product problems into clear, testable specifications that agents can execute against
You run end-to-end agent workflows to build features, then review the resulting change as a whole: correctness, consistency with our architecture, and drift, rather than line by line
You own what your agents ship to production: debug to root cause, and encode prevention (a test, a rule, an agent constraint) so the same issue is caught automatically next time
You ship small-to-medium features end-to-end with minimal guidance, including deployment
You build production-quality, reusable React components and integrate reliably with backend and third-party systems
You challenge unclear requirements, weigh business and user trade-offs, and communicate decisions and risks clearly to product and engineering partners

YOUR SKILLS MATTER

You hold a Bachelor's or Master's degree in Computer Science or a related field
You bring 3–6 years of frontend software engineering experience
You have strong React.js, Redux and framework-based JavaScript skills: component contracts, state management, and rendering/performance behavior. This depth is non-negotiable, as it's what lets you review and trust agent output
You are proficient with HTML, CSS, JSON, build tools, Git, and confident debugging in Chrome DevTools
You actively use AI coding assistants such as Claude or Cursor to accelerate your development, while applying sound engineering judgment to validate, review, and own the output
You work well with product, design, and engineering stakeholders
