📋 Description

• You develop scalable backend services in Node.js/TypeScript on AWS Lambda and reliably bring new features into production. • You model performant DynamoDB data structures and design data models tailored to real-world usage scenarios. • You design, implement, and operate robust APIs with AWS API Gateway, including clear error handling and operational stability. • You work with Infrastructure as Code (AWS CDK / CloudFormation) to ensure reproducible, maintainable deployments. • You develop and integrate React frontends so product ideas can be implemented end-to-end (backend remains your primary focus). • You ensure quality through code reviews, automated tests, and monitoring/observability. • You pragmatically use modern AI tools (e.g., Claude Code, Copilot) for code comprehension, refactoring, and documentation. • You collaborate closely with Product, Frontend, Data, and DevOps teams and actively contribute to technical decisions.

🎯 Requirements

• Several years of experience as a Senior Fullstack Developer or Senior Backend Developer. • Strong expertise in Node.js and TypeScript. • Deep experience with AWS, particularly Lambda, API Gateway, DynamoDB, and S3. • Experience with serverless and event-driven architectures. • Solid knowledge of React to implement frontend work when needed. • Experience with CI/CD, monitoring/observability, and cloud security (IAM, least privilege). • Structured working style, ownership mentality, and high quality standards. • German at least C1 level (important for team collaboration), good English.

🏖️ Benefits

• Product with real impact: you’ll build a digital co-pilot for the real estate and finance sector that relieves advisors and noticeably simplifies processes. • Modern AWS serverless architecture: Lambda, DynamoDB, and API Gateway — scalable, efficient, and product-focused. • High ownership & scope to shape the product: you make technical decisions and deliver features end-to-end into production. • Collaborative, equal-footed teamwork: close alignment within the product trio and with Frontend, Data, and DevOps. • Contemporary working practices: AI tools (e.g., Copilot/Claude Code) support refactoring, comprehension, and documentation — with a focus on quality rather than a feature factory.
