👥 Deine Rolle im Team

We’re looking for a Senior Backend Developer with a strong architectural mindset to help us evolve our Laravel-based SaaS platform. The position works in a hybrid work model (one office day per month). This is a hands-on role with a clear balance of responsibilities:

• building, reviewing and optimising backend features in Laravel
• creating, extending and maintaining our architecture and system design, ensuring the platform remains scalable, decoupled and easy to change

You’ll work closely with fellow developers, product and the CTO to deliver high-quality code, shape key technical decisions, keep the team aligned on standards and best practices, and drive complex integrations with third-party systems while leading AI-related initiatives — from embedding AI features into our product to using AI-assisted development tools to accelerate delivery.

Backend Development

• Design, implement and maintain backend services and RESTful APIs in Laravel (PHP)
• Ship production-ready code, write tests and perform thorough code reviews
• Optimise performance through profiling, query tuning and caching strategies
• Implement and maintain integrations with payment gateways, access control systems, CRM platform s and other third-party APIs
• Use AI-assisted coding tools where appropriate to boost efficiency and maintain quality
• Improve robustness by enhancing error handling, resilience and reliability
• Contribute to shared libraries within the mono-repo and keep dependencies healthy
• Collaborate with frontend engineers (Vue.js) to refine API contracts and data models

Architecture & System Design

• Contribute to the evolution of our Laravel architecture within a mono-repo setup
• Help define modular boundaries, integration patterns and shared model ownership
• Improve API design, versioning, documentation and decoupling practices
• Provide architectural input via RFCs, ADRs, design reviews and technical guidelines

Collaboration & Ways of Working

• Align backend and frontend teams on conventions, shared libraries and contribution rules
• Participate in architectural syncs, raise technical risks early and propose pragmatic solutions
• Encourage the adoption of AI in the development workflow
• Mentor peers through pairing, reviews and knowledge-sharing sessions

DevOps & Infrastructure (Azure)

• Help guide and improve Azure cloud infrastructure and deployment strategy
• Promote consistent infrastructure-as-code practices (ARM/Bicep/Terraform)
• Support observability improvements across logging, monitoring and alerting
