Application Engineer - III

Location: Malvern, PA

Time Type: Full time

Job Description

Job Description Summary

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.

Core 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.

Nice to Have

• 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.

Qualifications

• Bachelor’s degree in Computer Science or a related field (or equivalent practical experience).
• 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.
