Senior Full-Stack Developer

Your mission Build the next digital generation of Storage24 Storage24 is the European leader in XXL self-storage and flexible space solutions. After rapid expansion, we are now building a data-driven, scalable digital platform. We're looking for a Senior Full Stack Developer who thrives with high autonomy, takes ownership without being told twice, and delivers real impact — someone who's built things in a vibrant, fast-moving, ideally startup environment and knows how to figure things out when the path isn't fully mapped out yet. You'll work closely with Product and business leadership and take end-to-end ownership of key platform initiatives. You will: Build and extend platform features & internal tools Design and optimize data pipelines & integrations Operate scalable services on Google Cloud Maintain CI/CD pipelines & deployment environments Ensure quality through testing and code reviews This is not a ticket role. It's architecture, ownership, and shipped value — you'll often get direction on the what, not the how, and we expect you to run with that.

Mindset You've worked in a dynamic, fast-paced environment — startup experience strongly preferred — and know what it's like when priorities shift daily and nobody hands you a spec You take senior-level ownership end-to-end, and you don't wait around for instructions to get started You're comfortable making decisions with incomplete information and taking initiative without being asked You think in products and outcomes, not just features You choose pragmatic solutions over over-engineering You stay curious and leverage modern tools (including AI) to improve quality and speed This Is Who We Are Real ownership and direct influence on architectural decisions Direct impact on customer success and operational efficiency Opportunity to work with motivated stakeholders across the business Modern stack without legacy baggage Short decision-making paths, high autonomy and collaborative culture Hybrid setup: Munich office + 2 remote days Competitive compensation and attractive benefits (pension plan, bike leasing, corporate benefits, and more) About Us Storage24 offers the right space for companies, craftsmen, founders and private individuals to successfully implement their ideas and projects.
