Axiado is a fast-growing semiconductor company pioneering Trusted Control/Compute Unit (TCU) solutions that combine advanced hardware security, AI-driven resilience, and real-time platform management for data centers and cloud infrastructure. The company, founded in 2019 with over 150 employees, has been recognized as one of Fast Company's 2025 Top 10 Most Innovative Companies in Security.
As Senior QA Engineer – Performance & Reliability, you will lead the performance characterization and reliability validation of Axiado's Secure TCU System, ensuring it meets rigorous data center standards. You will own the complete test lifecycle—from design through execution to deep-dive analysis—working closely with firmware and hardware development teams to identify bottlenecks and resolve complex system-level issues.
Key responsibilities include:
**Performance & Reliability Strategy:** Design and execute comprehensive test plans for performance benchmarking, stress testing, longevity/endurance testing, and thermal/power characterization of TCU/BMC systems. Analyze system behavior under heavy workloads to identify performance bottlenecks in throughput, latency, and resource utilization (CPU, Memory, PCIe). Conduct Mean Time Between Failures (MTBF) prediction, long-duration stability tests, and error injection campaigns to validate system robustness.
**Deep Dive & Issue Resolution:** Lead root-cause analysis investigations of performance degradation and reliability failures using advanced debugging tools (oscilloscopes, logic analyzers, firmware traces). Work directly with engineers to reproduce complex bugs, analyze crash dumps, and verify fixes. Develop and maintain automated performance testing frameworks and reporting dashboards to track regression and trends.
**Reporting & Leadership:** Generate detailed performance assessment reports and reliability analysis metrics for stakeholders. Mentor junior engineers on performance testing methodologies and system debugging techniques.
**Requirements:**
- 5+ years of experience in embedded system testing with strong focus on performance verification and reliability engineering
- Deep understanding of TCU, BMC, HMC, RoT (Root of Trust), Secure Boot, TPM, HSM, PCIe (Gen4/5), DDR memory, and networking protocols
- Proficiency with performance profiling tools, traffic generators, and standard benchmarks (SPEC, IOzone, iperf); experience with thermal and power measurement tools
- Strong scripting skills in Python for test automation and data analysis; familiarity with C/C++ for code analysis is a plus
- Strong Linux/Unix skills, including kernel tuning, system monitoring, and log analysis
- Experience with CI/CD pipelines (Jenkins, GitLab CI) and version control (Git)
- BS/MS degree in Computer Science, Electrical Engineering, or related field
**Preferred qualifications:** Experience with AI-driven log analysis or anomaly detection tools; 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 (Telcordia, JEDEC).
