Lead Fullstack Developer (m/f/d) - SCAYLE Project Delivery Add-ons - Hamburg or Berlin (hybrid)

As part of SCAYLE’s Add-on Unit, we build modular, plug-and-play e-commerce solutions that extend the SCAYLE commerce engine and enable additional capabilities for our tenants.

As a Lead Fullstack Developer, you take full technical ownership of the unit’s output. You architect, build, release, and operate scalable add-ons across the entire stack using Laravel and Vue.js 3. You ensure performance, security, and maintainability while guiding the team through complex technical decisions.

This is a senior, hands-on leadership role requiring 10+ years of experience in building and operating scalable web applications in production environments.

What you will do

• Own the end-to-end architecture of modular add-ons (backend, frontend, integrations) and ensure scalability, security, and maintainability

• Design and implement advanced backend logic (Laravel, queues, events) and complex database schemas optimized for high-traffic e-commerce environments

• Oversee frontend integration within a micro-frontend setup (SingleSpa), ensuring seamless performance and UX consistency

• Lead CI/CD, semantic versioning, Docker-based environments, and release processes with stable rollouts

• Ensure production reliability through monitoring, alerting, and proactive incident response (e.g., DataDog, AWS environments)

• Act as technical lead and final reviewer, mentoring engineers, enforcing high code quality standards, and driving architectural consistency

• 10+ years of experience building, scaling, and operating complex fullstack web applications in production environments, ideally within e-commerce or SaaS ecosystems

• Expert proficiency in PHP (8.x) and Laravel (including Middleware, Queues, Events, Gates/Policies), along with strong experience in Vue.js 3, TypeScript, and modern state management (e.g., Pinia)

• Deep architectural expertise in designing secure, multi-tenant, and distributed systems, with strong understanding of SOLID/DRY principles and long-term maintainability

• Advanced database and performance engineering skills (MySQL/RDS, complex schema design, indexing strategies, Redis caching) in high-traffic environments

• Proven ownership of DevOps-adjacent responsibilities, including Docker-based environments, CI/CD pipelines, semantic versioning, AWS infrastructure awareness, and production monitoring/alerting

• Strong technical leadership skills: mentoring senior engineers, conducting high-quality code reviews, decomposing complex problems, and translating technical decisions into clear business impact
