• Supporting platform upgrades and ensuring applications remain secure, maintainable, and operationally stable.

• Contributing to CI/CD improvements, automated testing, and modern DevSecOps practices.

• Collaborating with the development team to improve engineering practices, knowledge sharing, and continuous improvement.

• Promoting the use of AI-assisted development tools to improve productivity, software quality, testing, documentation, and troubleshooting.

Who we are looking for:

• Strong experience developing enterprise applications using .NET/C#, APIs, and relational databases.

• Proven experience working with legacy systems, application modernization, and long-term application maintenance.

• Experience planning and executing framework and platform migrations to supported .NET versions.

• Hands-on experience migrating development platforms and CI/CD pipelines from Azure DevOps to GitHub/GitHub Actions.

• Experience identifying and mitigating technical debt, lifecycle risks, and security vulnerabilities.

• Familiarity with software lifecycle management, dependency management, and modern DevSecOps practices.

• Strong understanding of automated testing, code reviews, CI/CD, and modern software engineering practices.

• Experience working in agile development teams and environments moving toward trunk-based development.

• Practical experience using AI-assisted development tools in software engineering is highly valued.

• Strong analytical and problem-solving skills with a proactive, solution-oriented mindset.
