We're looking for a mature, Senior / Lead PHP Engineer with deep Laravel expertise and hands-on experience building or integrating agentic AI systems. Over a 6-month engagement, you will help the team build the next major product release, taking ownership of complex backend features end-to-end, mentoring other engineers, and helping shape how AI-driven automation and agents fit into the product and internal workflows.

You will join the cross-functional product team, working full time in the EDT (Toronto) time zone alongside engineers who value clear communication, independent judgment on ambiguous problems, and production-ready engineering.

Responsibilities:

• Design, build, and maintain robust backend services and APIs using PHP and Laravel to deliver the next major product release.
• Own features from technical design through deployment and monitoring.
• Integrate and orchestrate agentic AI workflows (e.g., LLM-based agents, tool-calling pipelines, autonomous task runners) into existing products and internal tooling.
• Improve system performance, reliability, and security across the stack.
• Mentor other engineers and partner with colleagues across functions to move technical topics forward.
• Stay current with the PHP/Laravel ecosystem and emerging agentic AI tools and patterns.

Requirements:

• 6+ years of professional PHP development experience, including 4+ years building applications with Laravel (or comparable modern PHP framework experience with strong Laravel proficiency).
• Hands-on GenAI experience - you've built with LLM APIs, tool/function calling, retrieval, agents, or agent frameworks and put them into real workflows.
• Modern AI coding tools (e.g., Claude Code, Codex) are part of how you work day to day.
• Solid database skills (MySQL/PostgreSQL), including query optimization and schema design.
• Familiarity with containerization (Docker) and cloud deployment (AWS, GCP, or similar).
• Solid engineering fundamentals: testing, debugging, code quality, and getting things production-ready.
• Strong communication and collaboration skills, with the judgment to work independently on ambiguous problems.
• English level: Upper-Intermediate or higher.

We offer*:

• Flexible working format - remote, office-based or flexible
