In this role you will independently investigate and drive resolution for complex product issues affecting enterprise customers. You will own technical diagnosis within your assigned problem space contribute code-level fixes and tooling improvements and partner closely with Support QA and core engineering teams to improve product resiliency and serviceability.

You will be expected to:

• Work with substantial autonomy on complex debugging and triage efforts.
• Make sound technical decisions during production investigations and on-call situations.
• Influence engineering quality through root-cause analysis design feedback and reusable diagnostic tooling.
• Mentor less experienced engineers through strong debugging practices and customer-focused engineering judgment.
• Use modern automation and AI-assisted workflows responsibly to accelerate analysis improve troubleshooting efficiency and validate outputs before adoption.

Responsibilities

• Investigate and resolve complex customer-reported issues across Nasuni’s hybrid cloud storage platform.
• Debug Linux-based systems software across C C++ Python and Bash codebases.
• Analyze logs traces core dumps protocol behavior and system performance data to identify root cause and recommend durable fixes.
• Develop and maintain diagnostic automation and supportability tools that improve troubleshooting speed and service quality.
• Partner with Customer Support QA and Core Development to reproduce issues isolate failure modes and improve product resilience.
• Participate in design and code reviews with a focus on operability serviceability and customer impact.
• Contribute fixes and engineering improvements related to storage networking authentication and system performance.
• Apply AI-assisted tooling where appropriate to accelerate investigation summarize patterns or improve workflow efficiency while verifying technical accuracy and production suitability.
• Mentor junior engineers in debugging discipline escalation handling and enterprise support best practices.
• Participate in a quarterly 24x7 on-call rotation.

Must-Have Qualifications

• 5–8 years of professional software engineering experience including meaningful time in Linux-based systems or infrastructure environments.
• Strong hands-on proficiency in C or C++ plus practical scripting ability in Python and Bash.
• Experience debugging production issues in Linux systems software infrastructure software storage platforms or similarly complex environments.
• Strong understanding of Linux internals including services/process management networking storage behavior and security fundamentals.
• Experience working with file or network protocols such as NFS SMB/CIFS or related enterprise storage connectivity layers.
• Hands-on experience with debugging and diagnostic tools such as gdb tcpdump wireshark valgrind or equivalent.
• Ability to perform structured root-cause analysis and translate findings into code fixes tooling improvements or product recommendations.
• Experience collaborating across engineering QA and support functions in customer-impacting environments.
• Strong written and verbal communication skills especially in high-urgency technical situations.
• Practical fluency with AI-assisted engineering tools for analysis debugging documentation or workflow acceleration with sound judgment in validating outputs before use.

Preferred Qualifications

• Experience with filesystems such as XFS or EXT4 and performance analysis in Linux environments.
• Familiarity with authentication and directory services such as Active Directory or LDAP.
• Experience with SQL or PostgreSQL in troubleshooting or systems contexts.
• Experience with enterprise virtualization platforms such as ESX Hyper-V or KVM.
• Familiarity with cloud platforms such as AWS Azure or GCP.
• Experience with CI/CD tooling build pipelines or packaging systems such as Jenkins GitHub Actions rpm or yum.
• Experience supporting enterprise customers in highly available or mission-critical environments.

Ideal Qualifications

• Experience debugging distributed storage file infrastructure edge appliances or hybrid-cloud platforms.
• Demonstrated history of building reusable internal tooling that measurably improved supportability time-to-resolution or engineering efficiency.
• Strong cross-functional credibility with Support and Product Engineering teams.
• Experience applying AI-assisted workflows to accelerate investigation or triage while maintaining strong technical validation and data-handling judgment.
• Open-source contributions or prior participation in community-driven engineering projects.

Experience Guidelines

• Total experience: Typically 5–8 years in software engineering systems engineering or platform engineering roles.
• Relevant domain depth: Typically 3+ years in Linux-based systems infrastructure storage networking or production debugging environments.
• Languages: Practical production-level depth in C or C++ with working proficiency in Python and Bash.
• Environment: Experience in enterprise SaaS infrastructure storage virtualization or similarly complex technical ecosystems is strongly valued.
