About The Position

We’re seeking an Application Engineer III to join our dynamic team. This role is primarily focused on AEM headful architecture, delivering rich, component-driven, omni-channel user experiences. You will contribute across the full development lifecycle—architecture, UI development, testing, and operations—while influencing engineering standards and supporting technical excellence across the team.

Requirements

5–7+ years of hands-on software engineering experience, with deep expertise in AEM UI development and architecture.
Proven experience delivering headful AEM solutions from build through launch, including components, templates, content governance, and integrations.
Strong experience with frontend engineering within AEM, including performance optimization, accessibility (WCAG), and SEO best practices.
Working knowledge of API-first development (REST/GraphQL), CI/CD pipelines, and automated testing.
Solid understanding of secure coding practices and scalable AEM architecture.
Strong communication skills and the ability to collaborate effectively across engineering, product, and design teams.
Demonstrated commitment to continuous learning, technical growth, and engineering excellence.
Bachelor’s degree in Computer Science or a related field (or equivalent practical experience).

Nice To Haves

AEM Cloud, AEM Core Components, Adobe Launch, Adobe WebSDK, Adobe Target, and Adobe Experience Platform (AEP).
Cloud experience (AWS or Azure), including services such as CloudFront, S3, IAM, Lambda, and containerized runtime environments.
Experience with modern frontend frameworks such as React, Angular, or Web Components (Lit), particularly when integrated into AEM UI patterns.
Exposure to headless AEM implementations or hybrid delivery models (not the primary focus, but beneficial).
Experience integrating mobile applications (iOS/Android) with AEM services.
Familiarity with AI-assisted development tools (e.g., GitHub Copilot, Claude Code).
Experience supporting omnichannel digital experiences across web and mobile platforms.

Responsibilities

Design and develop AEM Sites–based (headful) experiences, including components, templates, dialogs, and content models using Sling Models, OSGi, and HTL.
Build high-quality, performant, and accessible UI experiences using HTML, CSS, JavaScript, TypeScript, and Java.
Partner closely with UX and design teams to translate design systems into reusable AEM components and author-friendly experiences.
Implement hybrid AEM patterns where appropriate, including Content APIs, GraphQL, and reusable UI libraries—while maintaining headful AEM as the primary delivery model.
Integrate AEM with enterprise platforms and downstream services using REST and GraphQL APIs.
Ensure consistency in content structures, data models, caching strategies, and overall site performance.
Contribute to CI/CD pipelines, automated testing, code quality gates, and observability tooling.
Support performance optimization, including Dispatcher/CDN configuration, caching strategies, and image optimization.
Troubleshoot production issues and contribute to operational excellence and platform stability.
Collaborate closely with Product, UX, MarTech, Cloud, and cross‑functional teams to align on architecture, content governance, and delivery standards.
Participate in architecture discussions, design reviews, peer code reviews, and pair programming.
Share knowledge, mentor teammates, and support onboarding of new developers.
