Software-Architect / System-Designer (100% Remote)

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/Cursor/Codex, 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

• 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

• Contribute to architecture decisions, the direction of our stack, and the overall product vision

• Operate in an AI-first development setup powered by Claude/Cursor

owing company sounds like what you're after, we'd be glad to receive your application.

• 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

Please note that the application form on the next page is in German. That said, German language skills are not required for this role.
