• Take end‑to‑end ownership of projects, coordinating across technologies, services, and stakeholders to ensure successful delivery.

Requirements:

• Several years of professional experience developing large‑scale, scalable APIs and backend systems.
• Strong passion for API design, with the ability to think clearly about interfaces, architecture, and well‑structured data models.
• Deep expertise in Node.js and TypeScript.
• Strong experience with databases and data technologies such as PostgreSQL, MongoDB, ClickHouse, Redis, or Kafka.
• High standards for stability, developer experience, performance, and code quality.
• Demonstrated ability to take end‑to‑end ownership of projects and deliver results across different technologies, services, and teams.
• Strong proactive communication skills in both German and English, with the ability to communicate clearly and precisely in a remote and partially asynchronous environment.
• Comfortable working in a small team where individual contributions have a significant impact on the product and its users.
• Nice to have: Experience working with financial, stock market, or cryptocurrency data.
• Nice to have: Experience with LLMs and AI agents, particularly when processing large volumes of data.
• Nice to have: Experience building backend systems for complex data dashboards and visualization products.

Benefits:

• Competitive salary: €60,000–€90,000 fixed annual salary.
• Equity participation: VSOP opportunity, allowing employees to participate in the company’s long‑term value creation.
