DE Software-Architect / System-Designer (100% Remote / German-Speaking)

Fluent German is required for this role. Our customers are property management companies in Germany.

We're seeking an experienced Software architect / Full-Stack Developer who thinks like a Systems Designer - someone who reaches for schema diagrams and load assumptions before reaching for code. You'll join our fully remote team. If you like complexity, enjoy reasoning about data, scale and reliability, want to implement AI-solutions and enjoy working with Claude, this could be the right role for you.

What you'll do

• Own the system design - you decide how data is modeled, where state lives, how components talk to each other, and how the whole system behaves under load. You stay responsible for it once it's live.
• Make the hard, hard-to-reverse design decisions early - and reason explicitly about the trade-offs behind them
• Design and own our data layer from the ground up for new features - tables and relationships, indexing strategy, and query/load optimization that holds up as data and traffic grow
• Design queues, background jobs and long-running workflows that stay correct and reliable under heavy load and partial failure
• Talk to customers to understand how they actually use the product, and bring that into architecture decisions, the direction of our stack and the overall product vision
• Work independently in an AI-first development setup with Claude

For a closer look at what we're building, check out our YouTube channel - heads up, it's in German.

• Fluent German, spoken and written
• A genuine systems-design background - you can design a database from scratch (tables, relationships, indexes) and reason about database load, query performance and data growth, not just write CRUD against an existing schema
• The instinct to think in terms of consistency, throughput, failure modes and bottlenecks - you know where the system will hurt before it does
• Comfort designing queues, background jobs and long-running workflows, and the judgment to make the hard design trade-offs they involve
• You treat reliability, scalability and maintainability as default concerns. If you've read "Designing Data-Intensive Applications" (Kleppmann) - or simply think that way - you'll feel right at home here
• Solid English skills for smooth communication within the team
• You work autonomously and take full ownership of your tasks
• You're comfortable talking to customers to understand what they actually need

is not important to us, since AI will be writing 100% of your code.
