Senior Software Engineer (Perl)

Senior Software EngineerSoutron | Fully Remote | Full-time About SoutronSoutron builds specialist information, library, and archive management software used by corporate, legal, government, and research organizations around the world. Our platform helps teams curate, discover, and unlock the value of their most important knowledge assets — from legal precedent libraries to corporate archives to specialist research collections. We are a small, focused team that ships modern SaaS for a sector that has historically been under-served by technology. With new investment behind the business, we are modernizing the platform, expanding the product, and investing in the engineering team that will carry us into the next decade.About the RoleSoutron Global is looking for a Senior Software Engineer to be a key technical contributor on a mature, cloud-hosted SaaS library management platform serving 1,000+ public and K-12 school libraries across the United States. This is a rare opportunity to work hands-on with a stable, battle-tested codebase and a loyal customer base, and to help shape its technical direction over the coming years. You will report to the Director of Engineering and serve as a senior individual contributor and technical area owner for the platform — driving day-to-day development, contributing to infrastructure improvements, and partnering with the Director of Engineering on the modernization of the stack over time. You will work closely with the existing development team and benefit from a thorough, structured onboarding program. This is not a greenfield role. The right candidate is someone who is energized by going deep on a proven system, improving it methodically, and integrating seamlessly into an established engineering team — not someone who wants to rewrite everything from scratch.What You'll DoCodebase ownership — senior developer and technical area owner for the platform and ancillary projects, working alongside the Director of Engineering on architecture decisionsReleases and deployments — working within Soutron's established release process; understanding the current manual release cycle across 8 production servers and proposing improvements toward automated, pipeline-driven deploymentsInfrastructure awareness — not directly responsible for server administration, but expected to have working knowledge of the infrastructure stack (Debian Linux, Nginx, Apache/mod_perl, MariaDB/Galera, Solr, PowerDNS, Let's Encrypt) and to proactively identify and propose improvements to existing infrastructure patternsEngineering process adoption — adopting Soutron's established SDLC, Agile Scrum methodology, Bitbucket-based CI/CD pipelines, and code review practices across the acquired teamMentorship & engineering culture — share knowledge with peers, help raise the team's technical standards, and contribute to code review and engineering best practicesSecurity and compliance — dependency scanning, penetration testing coordination, MFA rollout, SOC 2 readiness roadmapPlatform modernization — progressively evolving the stack toward modern patterns (REST API layer, frontend modernization, containerization) without disrupting a live production systemWhat You'll BringThese are the core skills we're looking for. You don't need deep expertise in every item — if you're strong in most of them and motivated to grow in the rest, we want to talk.Perl (essential) — 5+ years of production Perl development; must be comfortable with mod_perl, CPAN module management, Template Toolkit, and navigating large, long-lived Perl codebases; experience modernizing or refactoring legacy Perl is a strong advantageApache Solr (essential) — 3+ years of hands-on Solr experience for search and indexing; understanding of index configuration, query tuning, and cluster management via Zookeeper; Elasticsearch experience considered in addition to, not instead of, SolrInfrastructure knowledge — solid understanding of Linux-based server environments (Debian/Ubuntu, Nginx, Apache, SSH, SSL/TLS); able to read, assess, and propose improvements to infrastructure configuration without necessarily owning day-to-day administrationRelational databases — MariaDB or MySQL; understanding of clustering and replication (Galera experience a plus)Full-stack web development — understanding of how server-rendered HTML applications work end-to-end; JavaScript (jQuery era and modern)Agile Scrum — proven experience working within an established Agile Scrum methodology; comfortable with sprint planning, standups, story pointing, and sprint reviewsSDLC practices — experience working within a formal software development lifecycle including code review, branching strategy, CI/CD pipelines, and QA gatesDevOps fundamentals — CI/CD pipeline setup, branching strategies, automated testing, deployment scriptingSecurity awareness — understanding of common web vulnerabilities (XSS, SQL injection, CSRF), CVE scanning, dependency managementCommunication and documentation —
