Job Summary

As a Backend or Fullstack Developer at addON Solution, you will play a pivotal role in the continuous evolution of the 'egON SalesCloud,' a proprietary cloud-native platform for digital sales and business processes. Your daily responsibilities involve developing high-performance, user-friendly web frontends and ensuring complex requirements are translated into clean, efficient code. You will bridge the gap between frontend components and backend services by integrating APIs and focusing on usability. Working within a collaborative environment alongside product management and backend teams, you will utilize modern development tools and AI-supported solutions to accelerate feature delivery. This position is particularly attractive because it offers the stability of a permanent contract and the chance to work on a dedicated internal product rather than shifting customer projects. You will have direct influence over the user experience and clear pathways for career progression into specialized frontend roles or technical leadership.
