• 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

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

Experience in frontend development withVue.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
