🤝 B2B

📋 Description

• You support our conversion team with the technical implementation of optimization initiatives: A/B testing — programming test scenarios for high-traffic e‑commerce shops. • Web development: build and adapt e‑commerce websites and landing pages according to design specifications. • Consulting: act as a technical sparring partner for our analysts when assessing the feasibility of test scenarios. • Quality: implement design mockups into clean, high‑performance code and perform QA checks before go‑live.

🎯 Requirements

• You are not a junior but an experienced developer who can quickly familiarize yourself with existing codebases. • Deep knowledge of HTML5, CSS3 and JavaScript. • Experience with frameworks/libraries such as Bootstrap or jQuery is expected. • Ideally, you have worked with tools like Kameleoon, Optimizely, AB‑Tasty or VWO (or can quickly get up to speed technically). • Basic understanding of Adobe Photoshop/XD for asset extraction is helpful. • Very good German skills (C1) are required for coordination with our analysts.

🏖️ Benefits

• 100% remote option or use of our office in the heart of Berlin — you decide. • Portfolio booster: work on projects for well‑known international brands and DAX‑listed companies. • Efficiency: short decision‑making paths, flat hierarchies and agile collaboration with an expert team of over 80 people. • An open, international mindset (17 nationalities) without agency politics.
