Vanguard Application Engineer - III in Malvern, Pennsylvania

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.
