Working Student: Frontend Development & Testing - Bremen

We are OH-SO, a digital agency leading the e-commerce replatforming of three Sports brands — onto Shopify as their new unified commerce platform.

All three builds share a common tech backbone, including Shopify storefronts, custom middleware (ASBUS), and integrations with Fluent OMS, Adyen, Auth0, and Salesforce Marketing Cloud.

We are now entering the active build phase and are looking for a motivated Working Student to support frontend development and testing across all three brands.

You’ll join a growing, AI-native agency that is redefining how brands combine creativity and technology — with both soul and system.

Powered by WPP, OH-SO was founded in 2024 in Hamburg and now employs around 50 people across offices in Berlin, Prague, and Munich.

We create pinnacle digital experiences paired with high-performance workflows — designed to spark ideas, save time, and deliver lasting impact for brands like Audi, Volkswagen, Otto, TÜV Rheinland, PowerCo, and CGM.

What You’ll Do

• Support frontend development using Shopify, Liquid, and React
• Assist in testing and quality assurance of features and integrations
• Help implement custom UI components and interactions
• Collaborate closely with designers and developers

What You Bring

• Hands-on experience in frontend development (e.g. HTML, CSS, JavaScript, React)
• Affinity for or experience with testing and quality assurance
• Attention to detail and a sense for UI/UX
• A proactive, hands-on mindset with curiosity to learn

Our Culture

Our team combines a hands-on mentality with a bird’s-eye perspective and a long-term mindset — driving meaningful progress and contributing to a world worth living in.

Mix of office and remote work. We value face-time for collaboration and whiteboarding, but trust people to manage deep work from wherever suits them.

Proactive updates, clear documentation, and the maturity to flag risks early. Agency pace means we ship frequently.
