Job Description

SCAYLE is one of the fastest-growing enterprise commerce platforms in the world, enabling brands and retailers to realize their D2C ambitions. SCAYLE stands for innovation, international collaboration, and a strong focus on data. We believe that stepping outside of our comfort zone and making bold decisions is key to growing both professionally and personally. Instead of seeing problems as obstacles, we approach them as opportunities to find better solutions. We work in an environment that encourages flexibility, creativity, and continuous development. What drives us is the shared motivation to make an impact and actively shape the future of eCommerce.

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. You champion the use of AI and agentic coding tools across the team, continuously exploring how they can raise both productivity and quality.

  • 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
  • Drive the adoption of AI-assisted and agentic coding workflows within the team, establishing best practices, guardrails, and quality standards for their use in production development

Qualifications

  • 8+ 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 frontend development

  • Expertise in Vue.js 3, TypeScript, and modern state management (e.g., Pinia) are a great plus

  • 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

  • Hands-on experience with AI-assisted and agentic coding tools (e.g., Claude Code, Cursor), with a clear point of view on where they add value and where they don't

  • Genuinely curious about the AI space, you stay current with new tools, models and methodologies, and you're keen to test what can measurably improve developer productivity and code quality
