Senior Full-Stack Developer (m/w/d) for Storage24

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.

Your profile Technical Expertise - 3+ years of experience as a Full Stack Developer (or equivalent hands-on depth — we value real coding experience over titles) - Strong experience with modern TypeScript & React - Confident working with SQL and data modeling - Experience building and operating services in Google Cloud - Familiar with Infrastructure-as-Code and CI/CD workflows - Comfortable designing APIs, integrations, and scalable architectures - Fluent in English (German or French is a plus) Nice to have: HubSpot, n8n, BigQuery, Docker, Tailwind, ETL/data engineering, event-driven systems. 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)
