Adobe Experience Manager Developer

At ESO, we believe in the power of science to expand the frontiers of human knowledge. Our digital platforms are key to sharing this mission with the world - and we're looking for a skilled and proactive AEM Developer to help build, operate, and evolve the technical foundations of ESO's online presence.

• In this role, you will contribute to the development of ESO's web platforms as Adobe Experience Manager (AEM) is introduced as the future core Content Management System. As part of ESO's Digital Communications team, you will help shape the technical implementation of a modern CMS landscape that supports ESO's public-facing communication platforms and enables teams across the organisation to publish content efficiently and reliably. You will develop and maintain AEM components and templates, work across frontend and backend systems, and contribute to building a robust, scalable, and user-friendly web platform.
• During the transition phase, ESO's existing Django/Python-based CMS will continue to run in parallel. Your responsibilities related to the legacy system will focus on keeping it operational through maintenance and essential minor updates. In parallel, you will support the technical aspects of migrating existing content into AEM, ensuring that content structures, templates, and components enable an efficient and reliable transition, while primary development efforts remain centred on the new AEM-based platform.
• Working closely with the Head of Digital Communications, the IT Department, and external providers, you will play an active role in shaping technical decisions related to AEM and the web frontend and help continuously improve ESO's digital platforms.

• To succeed in this role, you should bring:
• Several years of professional experience in web development, covering both frontend and backend
• Hands-on experience with Adobe Experience Manager (AEM), preferably version 6.5
• Strong backend development skills, especially in Java, HTL, Sling Models, and OSGi
• Solid frontend proficiency in HTML5, CSS3/4, JavaScript (ES5/ES6), and Webpack
• Experience with Git, Maven, and modular design using AEM ClientLibs
• A proactive, problem-solving mindset and strong communication skills
• The ability to work independently and collaboratively in a cross-functional team and across ESO
• A desire to contribute to science communication and support ESO's public mission
• Experience in the following areas would be an advantage:
• Experience with Django/Python-based CMSs or a strong willingness to learn
• Experience in large-scale content migration to AEM
• Experience coordinating with external development providers
• This is a unique opportunity to help shape the technical core of ESO's digital platforms - and to play a key part in how we share the wonder of astronomy and the engineering behind our telescopes with the world.
• Qualifications:
• A university degree in computer science, software engineering, web development, or a related field is preferred. Equivalent professional experience with a strong track record in CMS development and full-stack web engineering will also be considered.
• Language Skills:
• An excellent command of English is essential. A working knowledge of German and/or Spanish would be an advantage.
