Job Description

This role is responsible for hands-on maintenance, modernization, and reliable delivery of legacy Perl/CGI systems running on Linux, while actively contributing to CI/CD pipelines, build workflows, and incremental migration toward containerized infrastructure.

Job Summary

• Design, develop, refactor, and optimize Perl modules and legacy CGI applications for high-performance, secure production operations.
• Troubleshoot and resolve production issues end-to-end across system, application, and deployment layers, including memory leaks and performance bottlenecks.
• Own and improve Jenkins CI/CD pipelines, including build, release, versioning, and integration of static analysis tooling.
• Manage Linux server environments, covering processes, permissions, user/group management, cron, and performance monitoring.
• Write and maintain unit tests and runbooks to support reliability and knowledge continuity.
• Apply observability practices including structured logging, log rotation, telemetry, and actionable monitoring across Apache and application layers.
• Contribute to incremental modernization efforts, including migration from VM-based infrastructure toward containerized deployments.

Minimum Requirements

• 8-10 years of professional software development experience with strong, real-world Perl expertise including legacy Perl/CGI systems.
• Proficiency in Linux server operations (RHEL, CentOS, Debian, or Ubuntu) using CLI tools such as grep, awk, sed, jq, and diff.
• Hands-on experience with module management (CPAN, Makefile.PL, Build.PL), secure input handling, and performance tuning.
• Solid front-end proficiency in HTML, CSS, and JavaScript.
• Experience owning Jenkins pipelines (multibranch, Jenkinsfile), artifacts, credentials, and release cadence.
• Strong troubleshooting and root-cause analysis mindset with the ability to work independently in legacy and ambiguous environments.
• Demonstrated ability to collaborate effectively across distributed, cross-timezone teams.

Preferred Qualifications

• Experience with Angular or React in an enterprise development context.
• Containerization experience, including Docker and container-based deployments.
• AWS or cloud platform exposure.
• Familiarity with observability tooling such as OpenTelemetry or structured logging frameworks.
• Experience modernizing legacy systems incrementally, including VM-to-container migrations.
• Background with Node.js-based build tooling for static assets, including bundling, minification, and cache busting.
• Familiarity with enterprise tooling such as Jira, Bitbucket, GitHub Enterprise, Azure DevOps, or Octopus Deploy.
