Software Engineer, Wunderflats

• You're a Systems Thinker: You don't just write code; you model systems. You think about race conditions, data consistency, and edge cases before they become production incidents
• You Have a High "Say-Do" Ratio: You are accountable. You commit and you deliver. You communicate blockers with clarity and focus on outcomes, not activity
• You're Product-Obsessed: You understand the "why" behind the "what." You push back on requirements that don't make sense and collaborate to find the simplest solution that solves the user's problem
• You Thrive on Ownership: You want to own a problem, not just a ticket. You're comfortable taking a feature from an idea on a whiteboard to a deployed, monitored service
• Core Strength: Significant professional experience building and shipping applications using Node.js and TypeScript. You know how to build robust, scalable backend services
• Frontend Capability: You are proficient with modern React (with JS/TS) and have experience building and maintaining user-facing applications. Experience with Next.js is a strong plus
• While this is a full-stack role, the core challenge is on the backend. You are the engineer who is comfortable building a UI but is truly passionate about the reliability and architecture of the underlying financial systems

Desirable

• Most engineering jobs are about optimizing a button or maintaining a legacy system. This is not one of them. At Wunderflats, our vision of "living and working anywhere" hinges on one thing: trust
• Your mission as Software Engineer (f/m/d) will be to build and scale the engine of that trust — our core payments and pricing platform. You will own mission-critical financial systems from the database to the API to the user interface. If you're looking for leverage and direct impact on the business, this is it
• Does this sound like the right next step in your career? We would like to hear from you!
• Architect & Ship a Deposit Handling System: Design and deliver the functionality to securely hold and release tenant deposits. This is a greenfield project with massive impact on user trust and platform growth
• Evolve the Core Payment Ledger: You'll extend our rent collection system to handle complex payout schedules, split payments, and failure recovery. This requires deep systems thinking
• Build with Financial-Grade Reliability: Engineer fault-tolerant, idempotent systems. When you're moving money, "oops" is not an option. You will be obsessed with correctness, monitoring, and resilience
• Deliver End-to-End Features: Build not only the robust backend logic but also the clean React interfaces that allow landlords and tenants to manage these critical transactions with zero confusion
