Principal Software Engineer

Principal Software Engineer - C++ for Datapath Team

Nasuni is looking for a Principal C++ Engineer to help advance the core technology behind our cloud-native file data platform. This role is for a deeply technical C++/Linux engineer who has designed, optimized, and debugged performance-critical systems such as storage platforms, file systems, databases, or distributed infrastructure.

Responsibilities

• Own the design, implementation, optimization, and maintenance of critical data-path components within Nasuni’s platform.
• Improve read/write behavior, concurrency, throughput, latency, scalability, and reliability across performance-sensitive system paths.
• Lead technical investigations into complex defects, regressions, and customer-impacting escalations.
• Partner with QA and Performance Engineering to define test strategies, reproduce issues, measure improvements, and validate production readiness.
• Contribute to architecture reviews, coding standards, debugging practices, and technical direction across engineering.
• Use AI-assisted engineering tools thoughtfully for code exploration, test generation, debugging hypotheses, documentation, and analysis while validating correctness, security, and maintainability.

Qualifications

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or related technical field.
• 10+ years of software engineering experience, including 7+ years in storage systems, databases, distributed systems, or performance-critical infrastructure.
• Expert-level C++ and/or C programming on Linux.
• Strong experience with multi-threaded programming, concurrency, memory management, and systems debugging.
• Proven ownership of performance analysis and optimization using profiling, tracing, or diagnostic tools.
• Solid networking fundamentals and experience with application-level protocols.
• Clear written and verbal communication skills.

Preferred

• Experience with file systems, NAS, object storage, distributed storage, caching, metadata services, replication, snapshots, or consistency models.
• Python or Go experience for tooling, automation, test frameworks, or service integration.
• Experience supporting customer escalations or production-impacting engineering investigations.
• Familiarity with cloud infrastructure, SaaS product engineering, and secure engineering practices.
• Practical use of AI-assisted development workflows with strong validation discipline.

Expected Outcomes

In the first year, this engineer should improve core data-path reliability and performance, reduce repeat escalation patterns, raise design quality, and help Nasuni scale critical platform capabilities with clear technical ownership.
