Collaborate with UX and UI designers to translate designs into fast, intuitive, accessible experiences.
Ensure responsiveness and correct behavior across kiosk, large-format LED, desktop, and tablet form factors.
Design and extend Payload CMS collections, access control, and content models, plus the REST and GraphQL APIs that support content and configuration.
Collaborate on data modeling, schema design, system architecture, and integration patterns.
Write clean, maintainable, well-tested TypeScript with an eye toward long-term platform evolution.
Design or extend infrastructure as code (AWS CDK) to build immutable infrastructure deployable both in AWS and as constrained on-prem installations.
Participate in architectural discussions around data flow, caching, multi-tenancy, environment separation, and cloud-versus-on-prem deployment.
Review code, mentor other engineers, and raise the bar on code quality and system design.
Help improve developer tooling, workflows, and CI/CD over time.
