Jobbeschreibung

Senior Backend Developer (gn) // Hamburg // PHP, Laravel

The Company

Our client is a fast-growing technology company based in Hamburg that uses cutting-edge manufacturing technology to fundamentally transform a traditional industry. The engineering culture is defined by flat hierarchies, a high degree of ownership, and a serious commitment to quality. This is not a company that uses "innovation" as a buzzword; it builds accordingly. The backend team develops scalable APIs, operates live systems with real user volume, and has concrete strategic influence on architecture and infrastructure decisions.

Your Responsibilities

• You develop, test, and maintain scalable APIs (REST & GraphQL) with a consistent focus on code quality, security, and reusability.
• You share responsibility for live systems: monitoring, troubleshooting, performance optimization, and continuous improvement in production.
• You actively contribute to architecture and infrastructure decisions: your assessment of scalability and system design is expected, not merely welcome.
• You conduct code reviews, provide technical mentoring, and bring knowledge into the team in a structured way.
• You work closely with frontend developers, DevOps engineers, architects, and product management, and can communicate technical decisions clearly to non-technical stakeholders.
• You actively follow relevant developments in the backend space and translate new insights into concrete improvements.

What You Bring

• In-depth knowledge of Laravel and PHP, ideally including Laravel Nova
• Experience with Docker and container-based deployment
• Solid hands-on experience developing and integrating RESTful and GraphQL APIs
• Strong MySQL skills: schema design, query optimization, performance tuning
• Understanding of microservices and monolith architectures as well as scalability best practices
• Knowledge of authentication and authorization strategies (JWT, OAuth)
• Hands-on experience with CI/CD pipelines and automated deployment
• Experience with asynchronous processing, queues, and caching strategies
• Understanding of GDPR requirements and secure coding practices
• Git/GitLab for day-to-day collaborative work
• Nice to have: Python or Golang, AWS experience, basic frontend knowledge (React, Vue, Angular) in a backend integration context

What Awaits You

• Architectural influence from day one: you actively shape the product instead of working through tickets
• An interdisciplinary team of engineers, designers, and product thinkers without rigid hierarchies
• A growth trajectory in an industry that is currently reinventing itself, with the technical pace to match
• Hamburg location, flexible working models
• Diversity and inclusion as lived practice, not a corporate brochure
