The Senior Full Stack Developer role at Adversus A/S requires extensive experience in full stack engineering with a strong emphasis on both frontend and backend development. Key technical skills include proficiency in React, Typescript, and Tailwind for frontend development, alongside backend technologies such as PHP, NodeJS, and MySQL. Experience with asynchronous processing, data-driven programming, and handling large-scale task processing is essential. Familiarity with additional tools and frameworks like Redis, Elastic Search, WebRTC, SignalR, and RabbitMQ is also important to support integrations and real-time communication features within the sales acceleration platform. The position demands the ability to work on new feature implementation, improve existing automation systems, and prototype user interfaces with a focus on user experience. Candidates should be comfortable working with both modern and legacy technologies, demonstrating adaptability and problem-solving skills. Strong communication skills in English, reliability, discipline, and a collaborative mindset are critical for success in the team-oriented environment. While a relevant degree is a plus, it is not mandatory, highlighting the company's focus on practical expertise and business understanding. The role offers a dynamic setting within a growing company specializing in telecom, automation, and CRM integration, prioritizing high availability and usability. Overall, this senior-level position suits developers who are curious about new technologies, take ownership of their work, and thrive in delivering scalable, user-focused software solutions in a fast-paced, innovative environment.
