Job description

Senior QA Engineer – Performance & Reliability

• Full-time
• Compensation: USD 100000 - USD 160000 - yearly

Axiado is building the future of AI powered digital infrastructure. We are a fast-growing, well funded silicon, systems, and solutions company pioneering a new category of semiconductor called the Trusted Control/Compute Unit (TCU) that combines advanced hardware security, AI driven resilience and efficiency, and real-time platform management. Our technology protects the world’s most critical infrastructure—from data centers to next generation cloud and AI platforms—by securing systems at the foundation levels of hardware, independent of host CPUs and operating systems.

Founded in 2019 and now over 150 employees are strong, Axiado has evolved into a recognized leader in the convergence of AI, security, and silicon innovation. We partner with and are actively engaged in commercial programs with multiple Tier 1 industry leaders, validating both our technology and our long-term market trajectory. Axiado has also won numerous industry awards for our ground-breaking products and technological innovations, including being named one of Fast Company's 2025 Top 10 Most Innovative Companies in Security, winning the 2025 Global InfoSec Award for Outstanding AI Security Solution, and being named a finalist for the Global Semiconductor Alliance's 2025 "Start-Up to Watch" award.

At Axiado, developing breakthrough technology takes more than great engineering—it takes a team of exceptional people who collaborate boldly, challenge assumptions, and take pride in building what comes next. We value curiosity, execution, respect, and a shared desire to make a meaningful impact on the security and reliability of the digital world.

We value curiosity, execution, respect, and a shared desire to make a meaningful impact on the security and reliability of the digital world.

Axiado is a top-tier manufacturer of TCU (Trusted Control/Compute Unit) solutions. We are hiring a Senior QA Engineer – Performance & Reliability to lead the performance characterization and reliability validation of our Secure TCU System, ensuring it meets rigorous data center standards.

In this role, you will own the test design, execution, and deep-dive analysis for performance and reliability, working closely with development teams to identify bottlenecks and resolve complex system-level issues.

Key Responsibilities

Performance & Reliability Strategy

Test Design & Execution: Design and execute comprehensive test plans for performance benchmarking, stress testing, longevity/endurance testing, and thermal/power characterization of TCU/BMC systems.

Workload Analysis: Analyze system behavior under various heavy workloads to identify performance bottlenecks in throughput, latency, and resource utilization (CPU, Memory, PCIe).

Reliability Validation: Conduct Mean Time Between Failures (MTBF) prediction, long-duration stability tests, and error injection campaigns to validate system robustness.

Root Cause Analysis: Lead the deep-dive investigation of performance degradation and reliability failures. Use advanced debugging tools (oscilloscopes, logic analyzers, firmware traces) to isolate issues.

Developer Collaboration: Work directly with firmware and hardware engineers to reproduce complex bugs, analyze crash dumps, and verify fixes.

Infrastructure Enhancement: Develop and maintain automated performance testing frameworks and reporting dashboards to track regression and trends over time.

Reporting: Generate detailed performance assessment reports and reliability analysis metrics for stakeholders.

Mentorship: Mentor junior engineers on performance testing methodologies and system debugging techniques.

Experience: 5+ years of experience in embedded system testing, with a strong focus on performance verification and reliability engineering.

System Knowledge: Deep understanding of TCU, BMC, HMC, RoT (Root of Trust), Secure Boot, TPM, HSM, PCIe (Gen4/5), DDR memory, and networking protocols.

Performance Tools: Proficiency with performance profiling tools, traffic generators, and standard benchmarks (e.g., SPEC, IOzone, iperf). Experience with thermal and power measurement tools.

Programming: Strong scripting skills in Python for test automation and data analysis; familiarity with C/C++ for code analysis is a plus.

Operating Systems: Strong Linux/Unix skills, including kernel tuning, system monitoring and log analysis.

Tools: Experience with CI/CD pipelines (Jenkins, GitLab CI) and version control (Git).

Education: BS/MS degree in Computer Science, Electrical Engineering, or a related field.

Ways to Stand Out

Experience with AI-driven log analysis or anomaly detection tools to predict reliability issues.

Background in validation of high-speed interfaces (PCIe, CXL) and memory subsystems (DDR5/LPDDR5).

Experience with data center server architecture and thermal management.

Knowledge of industry reliability standards (e.g., Telcordia, JEDEC).

Note: We do not expect candidates to meet every single requirement. A strong core of these skills with a problem-solving mindset is what we value most.

Compensation Range - $80,000 - $200000
