Kubernetes with logging, monitoring and performance tracing.
What you'll bring

Modern PHP (8.x), good object-oriented design, and the habit of writing PHPUnit tests.
Performance work on a busy store
full-page cache, Redis, indexing and MySQL query tuning. An understanding of observability (logging, metrics and tracing) on a high-traffic store. Enough frontend to work in Magento themes: Knockout.js, RequireJS and Tailwind CSS. Daily use of Docker, Git and CI/CD. Kubernetes experience helps, and we'll get you up to speed if you're newer to it. Day-to-day use of agentic development tools, such as Claude Code or similar, in your engineering work. Using AI across the whole development cycle: scaffolding, code generation, refactoring, writing tests, code review, debugging and documentation. The judgement to check, test and take ownership of AI-generated code rather than accepting it as it is. Good prompting and context management on a real codebase. Experience with MCP-based integrations is a plus. A cool head under pressure, and the ability to explain trade-offs to engineers, product and QA. Nice to have Payment gateway integrations at scale. Getting a store ready for a seasonal peak: load testing, capacity planning, change freezes. Headless or composable commerce. Static analysis and mutation testing.
