Job description

What You Can Expect

For our client and portfolio company Storage24, we are looking for a

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.

What We Expect From You

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

What We Offer You

• 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)
