To become a senior remedy developer, you need to have a strong understanding of Remedy development and administration, as well as IT service management principles and processes. Proficiency in Remedy's development languages and tools, such as ARS, ITSM, Developer Studio, Atrium CMDB, Atrium Integrator, and Smart IT is also required. Additionally, knowledge of web development technologies like HTML, CSS, JavaScript, XML, and REST APIs is essential. Furthermore, experience with databases such as Oracle, SQL Server, and MySQL is necessary. The ability to design and implement Remedy workflows, forms, filters, escalations, notifications, and reports is also important. Debugging and optimizing Remedy code and performance is another key skill. Finally, strong communication skills to effectively manage expectations and deadlines are needed. A senior remedy developer should be able to work independently or as part of a team while managing multiple projects and priorities.
