Job Description

We are seeking a highly experienced and technically versatile Quality Engineering Architect to lead the end-to-end quality strategy for Infinia — DDN’s highly distributed data intelligence platform.

 

This role demands deep hands-on expertise in test automation frameworks, system-level validation, CI/CD integration, and large-scale platform reliability testing. You will be responsible for shaping the vision and execution of quality practices across Infinia’s distributed architecture — from low-level I/O and memory handling to high-throughput applications, multi-tenant services, and NVMe-backed storage systems.

 

This is a pivotal technical leadership role for someone who can architect at scale, automate with precision, and inspire quality-first thinking across engineering teams.

Key Responsibilities

Architecture & Strategy

• Define the Infinia-wide quality engineering architecture, driving consistency, testability, and observability across all subsystems (e.g., I/O Path, SPDK Data, Memory, Task Scheduling, Platform Services).
• Architect and evolve end-to-end test frameworks for performance, correctness, data integrity, and security compliance.

Automation & Infrastructure

• Lead the design and implementation of modular and scalable automation frameworks using tools like Robot Framework, Selenium, Pytest, Postman, JMeter, and containerized test environments with Docker, Jenkins, and OpenShift.
• Design reusable automation templates and CI pipelines to support rapid iteration and deployment with full validation gates.

Performance & Scale Testing

• Build and maintain comprehensive test plans that validate performance, workload behavior, concurrency, and cross-platform reliability at scale.
• Leverage profiling, fuzzing, and failure injection methodologies to ensure system stability under load, including NVMe performance tracing, network saturation, and long-duration testing scenarios.

 Leadership & Collaboration

• Partner with architects, developers, DevOps, and customer engineering to integrate quality into early-stage system and feature design.
• Lead risk-based test planning, root cause analysis for systemic issues, and verification of security and compliance requirements.
• Mentor engineers on test design, automation best practices, and quality standards across platform teams.

 Required Qualifications

• 15+ years of experience in software quality engineering, with extensive expertise in test architecture for distributed or cloud-native platforms.
• Deep experience with automation development using Python, Bash, and Git-based CI/CD environments.
• Proven success in architecting test frameworks across complex infrastructure components or platform services.
• Strong understanding of file systems, I/O stack behavior, storage profiling (NVMe, SPDK), and network observability.
• IST
