independently across customer support, product engineering, QA, and release operations.
Specific duties include but are not limited to:
• StorNext Sustaining Engineering Leadership: Serve as a senior technical owner for StorNext
software in production, with primary responsibility for Storage Manager and supporting
responsibility for StorNext filesystem-related issues, including:
◦ Lead root-cause analysis and resolution of complex customer escalations, including
crash dumps, field logs, and difficult-to-reproduce production issues.
◦ Partner with Product Management and senior engineering stakeholders to evaluate
feature requests, technical feasibility, risk, and long-term maintainability.

development, build, qualification, and customer environments.
◦ Create new VM templates for Linux (Alma, Oracle, Rocky, RedHat, Debian, Ubuntu,
SLES) and Windows 11
◦ Modernize, troubleshoot, and maintain deployment automation written in PHP, Perl, and
related scripting technologies.
◦ Resolve package manager, installation, networking, OS compatibility, and configuration
issues across supported templates.
• Offline File Manager (OFM) Technical Ownership: Act as the senior technical authority for
OFM support, maintenance, and knowledge transfer, including:
◦ Evaluate, debug, and resolve complex customer-reported OFM issues with a focus on
quality, reliability, and long-term supportability.
◦ Design and implement OFM enhancements requested by Product Management while
balancing customer impact, technical debt, and release risk.
◦ Mentor QA engineers and developers on OFM architecture, operational behavior,
troubleshooting methods, and best practices.
• Build Infrastructure and Release Enablement: Own and evolve the build infrastructure that
supports StorNext engineering and release workflows, including:
◦ Create, configure, and maintain VMs for new build machines and sustaining engineering
environments.
◦ Integrate packages, build systems, and automation workflows with Jenkins and related
continuous integration infrastructure.
• Customer and Cross-Functional Escalation Support: Engage directly with customers,
Support, QA, Product Management, and Engineering leadership to clarify issues, communicate
technical findings, and drive resolution of high-impact escalations.
Required Qualifications:
• 8+ years of professional systems software development experience using C and/or C++.
• Deep Linux systems experience across Red Hat and Debian/Ubuntu variants, including
installation, packaging, networking, services, and OS-level troubleshooting.
• Expert-level programming experience in C and C++ (C++11/C++17), with strong Python
scripting and automation skills.
• Advanced debugging skills using GDB, system logs, core files, crash dumps, and other
production diagnostic artifacts.
• Proven ability to perform root-cause analysis on complex, multi-process, distributed, or timing
sensitive software failures.
• Strong understanding of build systems, compiler behavior, linker errors, dependency
management, and release engineering workflows.
• Experience designing, debugging, and sustaining multi-process systems, inter-process
communication, and long-running services.
• Practical experience using AI-assisted development tools such as Claude Code,
including:
◦ MEMORY.md
◦ Skills
◦ MCP servers
◦ Multi-agent development
• Experience working in Scrum or similar agile development environments, with the maturity to
balance planned work, escalation response, and release commitments.
Preferred Qualifications:
• Windows and Mac development experience, especially in mixed-platform engineering or
customer environments.
• Experience with RPC, TCP, and other inter-process or distributed communication mechanisms.
• Additional language experience with Objective-C, Perl, PHP, Java, Assembly, JSON, or similar
technologies used in legacy enterprise software environments.
• Networking, authentication, and directory services knowledge, including SSSD and Active
Directory integration.
Ideal Candidate:
The ideal candidate is a senior, hands-on systems engineer who can operate as a technical owner
across sustaining engineering, customer escalation support, build infrastructure, and legacy platform
modernization. This person should be comfortable moving from low-level debugging to architecture
discussions, from customer-facing issue resolution to mentoring QA and development teams, and from
urgent field escalations to long-term improvements in reliability and maintainability. We recognize that
few candidates will bring every skill listed; we are looking for deep technical strength, strong ownership,
mature judgment, and the ability to quickly ramp into complex enterprise storage software.
