Software Development Engineer II (Frontend)

Software Development Engineer II (Frontend)

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
