Working Student (all genders) Product Design

You’re studying Product Design (or something close to it), love asking why, and get excited when you can actually improve things instead of just talking about them?

Perfect.

We’re looking for a Working Student to support our in-house Product Design team - someone who’s eager to get their hands dirty in usability testing, research, and real product decisions. This is not a “watch and learn from the sidelines” role. You’ll actively contribute, validate ideas, structure insights, and help shape user experiences in a fast-moving, startup-like environment.

If you enjoy turning feedback into action, love structured thinking, and want to see how design decisions are made in the real world - keep reading.

Your Mission

Support our Product Design team in turning user insights into better experiences - and better experiences into measurable impact. You’ll help us test, validate, research, structure, and execute. In short: you’ll make sure great ideas don’t stay ideas.

Your Responsibilities

1. Usability Testing & Validation Support

Prepare usability test scenarios and define clear objectives
Set up and manage research tools (e.g., surveys, testing setups)
Create surveys to validate design decisions (e.g., CTAs, buttons, interaction patterns)
Document user behavior and extract structured insights
Support in analyzing findings and identifying patterns and improvement areas

2. User Insight & Research

Conduct primary and secondary research (surveys, desk research, data reviews)
Perform competitive and market research to identify benchmarks and user expectations
Investigate specific UX topics using qualitative and quantitative methods
Synthesize findings into clear, structured summaries for design and product discussions

3. Ad-Hoc Design Support

Support designers with hands-on tasks across projects
Help finalize and update presentation decks (e.g., All Hands, stakeholder slides)
Assist with style guide tasks and maintaining visual consistency
Contribute to design tickets (e.g., banners, small execution tasks)

What You Bring

You’re currently studying Product Design or a related field (advanced Bachelor’s or Master’s level)
You’re available at least 15 hours per week
You have a strong interest in UX, usability testing, and design research
You enjoy structured thinking and working detail-oriented
You’re proactive and able to identify tasks independently
You’re comfortable working in a dynamic, fast-paced environment
Experience with Figma is a strong plus
German and English at C1 level
And most importantly: You’re curious. You ask questions. You don’t wait to be told every next step. You’re excited about turning feedback into better products.
