Job Description

We are seeking a highly skilled and technically strong Staff Engineer in Test to lead system level quality engineering efforts for networking, security and other enterprise readiness aspects of Infinia, DDN’s large-scale distributed data platform.

 

In this role, you will be a senior technical authority responsible for planning and implementing test strategies and test infrastructures to ensure correctness, stability, performance, and resilience of Infinia’s distributed architecture. You will work across core subsystems—including the I/O path, memory management, networking stack, scheduling layers, multi-tenant services, and NVMe-backed storage

patterns—to ensure platform quality at scale.

 

This is a hands-on, high-impact IC role for someone who can solve hard problems, automate at scale, leverage AI to improve velocity and elevate quality engineering across the organization.

 

Key Responsibilities:

 

Quality Engineering & System Validation

• Design detailed test strategies and validation plans for networking and security features for distributed system
• Create scalable, automated test suites that validate multi-tenant behavior, concurrency, data consistency, and system-level performance.

Automation Frameworks & Tooling

• Build and maintain robust automation using tools such as Pytest and container-based environments leveraging Docker, Jenkins, Kubernetes.
• Develop reusable automation templates, harnesses, and utilities to accelerate test creation and reduce engineering overhead.

Performance, Reliability & Scale Testing

• Construct and execute performance tests covering I/O throughput, system latency, NVMe access patterns, concurrency limits, and long-running workload stability.
• Use advanced tools (profilers, fuzzers, failure-injection frameworks, trace analyzers) to uncover issues in distributed workflows.
• Analyze CPU, memory, disk, and network utilization to diagnose performance bottlenecks and identify regression risks.

Cross-Functional Quality Leadership

• Work closely with architects, developers, release engineering, DevOps, and customer engineering to drive quality-first design decisions.
• Participate in feature design reviews, ensuring testability, observability, and resilience are built into system components.
• Lead root cause analysis (RCA) for complex issues and propose long-term improvements to engineering practices and platform stability.

Documentation & Quality Standards

• Produce clear, detailed test plans, automation guides, design-review feedback, and quality metrics reports.
• Contribute to the development and maintenance of internal QA standards, best practices, and. onboarding materials.

Required Qualifications

• 10+ years of experience in software quality engineering, with strong focus on distributed systems, system-level testing, or infrastructure plat
