DE Munich, DEOn-siteSenior

About the Role

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).

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.

Nice to Have

HubSpot, n8n, BigQuery, Docker, Tailwind, ETL/data engineering, event-driven systems.

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).
