Working Student Product Engineering Ruby on Rails for Auction Platform Kickdown all genders - Kickdown GmbH

Do you want to gain real startup experience while still studying and work on a product people actively use to buy and sell classic cars? At Kickdown, you help build a live auction platform with real users and real transactions.

We are looking for a Working Student Product Engineering (Ruby on Rails) who is curious about how products are built, not just how code is written. You will work on our auction platform using Ruby on Rails and collaborate closely with product and business teammates, with your work directly influencing user experience, trust, and conversion.

Our mission is to give service-driven owners and global collectors peace of mind when buying and selling German premium classics, through a seamless and transparent end-to-end transaction. You will help improve core user flows, look at how users actually behave in them, and turn that insight into small, testable changes, so you quickly see how your contributions affect the product.

You will be part of a small, focused team where decisions are made quickly and learning is hands-on. If you want to build meaningful software, understand how technology drives real products, and care as much about outcomes as output, we would love to hear from you.

Tasks

• You look at how users actually behave in our core flows (bidding, checkout, listing creation) and turn that insight into small, testable improvements, not just tickets to close.
• You develop and improve features for our auction platform, from idea to implementation, with a strong focus on users and product goals.
• You translate product ideas into technical solutions using Ruby on Rails, and learn how technical decisions impact user experience and conversion.
• You help design lightweight experiments on key flows, and use data to see whether they actually moved the needle.
• You use AI-assisted development tools in your daily work.
• You help improve our codebase by fixing issues, refactoring existing code, and learning how to maintain software quality.
• You work closely with product, business, and tech teammates to plan and implement solutions pragmatically.
• You participate actively in team discussions, share ideas, and take on more responsibility as you grow.

Requirements

• You are currently enrolled in a Bachelor's or Master's program in computer science, business informatics, or a comparable field, and available for 15 to 20 hours per week with flexibility during exams.
• You have initial hands-on experience in web development, ideally with Ruby on Rails, gained through projects, internships, or student roles.
• You think in terms of outcomes, not just output. You care whether a change actually improved the funnel as much as whether the code works, and you're comfortable using data to check.
