Role Overview
This role is for an experienced Sr. Linux Developer to support the migration of a Windows-based system to a dedicated Linux desktop environment for an IoT platform. The position will involve a blend of design and hands-on implementation (~40% design/engineering, 60% hands-on).

• Develop and implement strategies for system design, OS hardening, security lockdown, and software updates in a Linux environment.
• Collaborate with development and operations teams to ensure functional parity and system requirements are met.
• Identify and resolve compatibility issues, driver conflicts, and other platform-specific blockers during the migration process.
• Ensure the new OS configuration is hardened and securely configured for distribution.

Required Qualifications
Education: A Bachelor of Science in Computer Science, Computer Engineering, or an equivalent field is a firm requirement.
Experience: A minimum of 10 years of software development experience is required. Candidates must have a proven track record of planning and executing full Windows-to-Linux OS and application migrations in production environments.
Technical Skills:

• Deep expertise in Linux distributions (Ubuntu or Debian-based systems), including system hardening, package management, and configuration.
• Proficiency in Linux scripting (Bash) and software development in C# and C/C++.
• Experience porting or rewriting Windows-native code to Linux-compatible equivalents.
• Ability to design time-sensitive, high-availability solutions with high attention to detail.
• Familiarity with cloud environments (Azure preferred), IoT concepts, and containers.

Preferred Qualifications

• Experience with AI-assisted coding tools such as GitHub Copilot, Claude, or similar.
• Understanding of Service-Oriented Architectures (SOA).
• Experience deploying and managing Linux-based workloads on cloud platforms like AWS or Azure.
• Knowledge of containerization technologies such as Docker, Podman, or Kubernetes.
• Experience with Azure IoT solutions.
• Familiarity with web technologies like HTML, CSS, Blazor, or Razor for UI applications.
• Experience with Git-based version control (GitLab, GitHub, Bitbucket) and modern IDEs (Visual Studio, VS Code, JetBrains).
