Job Zusammenfassung
In dieser Rolle entwickelst du skalierbare Backend-Services in Go und implementierst performante REST APIs. Du überwachst die Datenintegrität, optimierst bestehende Systeme und gestaltest das Frontend mit Angular und TypeScript.
Job Technologien
Deine Rolle im Team
- itemdrop digitizes the cloakroom: our event-tech platform from Düsseldorf handles drop-off and pick-up in seconds. Over one million check-ins, around 50 customers, and real-time payments in production, even when a thousand guests arrive at once at night. Next up: scaling across Europe.
- As a Senior Backend/Fullstack Engineer, you'll primarily evolve our Go services for exactly that: more venues, more peak load, new integrations, tougher reliability. Where it makes sense, you'll also pitch in on the web frontend. You'll work in a small senior team directly with our Tech Lead, help shape architecture decisions, and ship in short cycles. AI tools like Claude Code are part of our everyday work.
- Design, develop, and maintain scalable backend services in Go.
- Design and implement performant, idiomatic REST APIs, including interfaces to internal and external systems as well as web and mobile clients.
- Take responsibility for transactional data: payments and credits without data loss, even at peak load.
- Performance and error monitoring, bug fixing, and optimization of existing services regarding performance, concurrency, and resource consumption, especially SQL queries and database interfaces.
- Light fullstack component: implement smaller features and adjustments in the web frontend end-to-end (Angular 21 with TypeScript, step-by-step migration from Angular Material to Tailwind CSS).
- Ensure code quality: code reviews, unit and integration tests, best practices, and adherence to existing guidelines.
- Contribute to architecture decisions and the further development of our CI/CD pipeline.
Unsere Erwartungen an dich
Ausbildung
- Completed vocational training in IT, an IT degree, or comparable practical experience.
Qualifikationen
- Awareness of transactional data and the risks of data loss or outages.
- You master your tools, especially for debugging and performance measurement.
- You write clean, tested code, work in a structured way, and communicate confidently in German or English.
- Knowledge of MariaDB (GORM), InfluxDB, or comparable databases.
Erfahrung
- Ideally three to five years of professional experience in backend development; you have a strong command of Go and SQL.
- Solid experience with REST and API-driven applications, from API design to consuming external APIs, for web and mobile clients.
- You understand how LLMs and AI agents work in software development, ideally with first hands-on experience in Claude Code, Codex, or Cursor.
- Nice-to-have: Production experience with Docker and Linux.
- Experience on the web frontend, ideally with Angular, TypeScript, and Tailwind CSS.
- First experience with webhooks, caching, and message queues (Kafka, RabbitMQ, Redis).
Unser Angebot
- €55,000-80,000 annual salary (depending on experience) plus equity option: you share in our success.
- Real ownership: you help shape architecture decisions, and your code runs in production within days, not quarters.
- Truly hybrid: remote whenever it works for you and your working model, plus regular shared days at our office in the heart of Düsseldorf.
- AI-first setup: modern hardware and all the AI tools that make you more productive. Claude Code & co. are part of everyday work.
- Impact over politics: lean hierarchies, results matter, speed over meetings.
- Predictable time and learning budget, lunch benefit, team dinners, and shared on-/offsites.
