Design and implement user interfaces for hosting panels and customer portals using HTML, CSS, and JavaScript. Support customers and internal teams in extending and adapting custom client portals developed in PHP. Develop event handlers and lightweight background applications that operate within a containerized infrastructure. Collaborate with cross-functional engineering teams to integrate PHP-based components with broader security products and services. Contribute to the full software development lifecycle, including technical design, implementation, testing, debugging, maintenance, and deployment. Apply web security principles and best practices to build robust integrations that help protect applications and online services against automated threats. Address technical challenges related to scalability, availability, performance, and system reliability, contributing to sustainable engineering solutions. Use development tools and technologies such as Git, Docker, SQL, XML, regular expressions, and CI/CD pipelines to support efficient software delivery. Participate in technical discussions, challenge existing approaches when appropriate, and collaborate with colleagues to identify and implement effective solutions. Continuously develop technical expertise by exploring new technologies, sharing knowledge, and contributing to improvements across the engineering organization. Requirements: At least 4 years of professional PHP software development experience, including a proven track record of delivering and maintaining long-term software projects. A solid understanding of how the World Wide Web works, including HTTP, web applications, client-server communication, and related technologies. Practical knowledge of web security principles, common vulnerabilities, and approaches to protecting online applications and services. Experience developing integrations, plugins, or extensions for web platforms, content management systems, or hosting control panels is highly relevant. Familiarity with HTML, CSS, JavaScript, SQL, XML, and regular expressions, with the ability to build and troubleshoot web-based interfaces and integrations. Experience with version control systems such as Git and development tools such as Docker, along with an understanding of modern software development workflows. The ability to think beyond individual features and consider broader engineering concerns, including scalability, availability, maintainability, and system performance. Strong problem-solving skills, sound technical judgment, and the confidence to question established approaches when better solutions are available. Excellent collaboration skills, with the ability to make decisions collectively, communicate technical ideas clearly, and work effectively with colleagues across different teams. Strong time management and asynchronous communication skills suited to a fully remote, distributed engineering environment. Curiosity, initiative, and a genuine willingness to learn unfamiliar technologies and continuously improve technical capabilities. Previous experience in the hosting industry is an advantage. Working knowledge of C++ or Go is a strong plus, particularly for engineers interested in integrating PHP components with broader security systems. Familiarity with technologies such as RabbitMQ, PostgreSQL, ClickHouse, Kubernetes, or GitLab CI/CD would be beneficial.
