SQA Engineer

About Celestial AI

As Generative AI continues to advance, the performance drivers for data center infrastructure are shifting from systems-on-chip (SOCs) to systems of chips. In the era of Accelerated Computing, data center bottlenecks are no longer limited to compute performance, but rather the system’s interconnect bandwidth, memory bandwidth, and memory capacity. Celestial AI’s Photonic Fabric™ is the next-generation interconnect technology that delivers a tenfold increase in performance and energy efficiency compared to competing solutions.

The Photonic Fabric™ is available to our customers in multiple technology offerings, including optical interface chiplets, optical interposers, and Optical Multi-chip Interconnect Bridges (OMIB). This allows customers to easily incorporate high bandwidth, low power, and low latency optical interfaces into their AI accelerators and GPUs. The technology is fully compatible with both protocol and physical layers, including standard 2.5D packaging processes. This seamless integration enables XPUs to utilize optical interconnects for both compute-to-compute and compute-to-memory fabrics, achieving bandwidths in the tens of terabits per second with nanosecond latencies.

This innovation empowers hyperscalers to enhance the efficiency and cost-effectiveness of AI processing by optimizing the XPUs required for training and inference, while significantly reducing the TCO2 impact. To bolster customer collaborations, Celestial AI is developing a Photonic Fabric ecosystem consisting of tier-1 partnerships that include custom silicon/ASIC design, system integrators, HBM memory, assembly, and packaging suppliers.

ABOUT THE ROLE

Celestial AI is looking for a highly motivated and detail-oriented Software Quality Assurance (SQA) Engineer to join our team. As an SQA Engineer, you will play a critical role in ensuring the quality of our software products. You will be responsible for designing, developing, and executing test plans and test cases, identifying and reporting defects, and working closely with developers to ensure that our software meets the highest standards.

ESSENTIAL DUTIES AND RESPONSIBILITIES

• Test Case Design & Execution: Design, document, and execute detailed test cases for firmware components, drivers, communication protocols, and system-level interactions with hardware.

• Hardware-Firmware Integration Testing: Lead and perform testing at the hardware-firmware interface, ensuring seamless and correct interaction between embedded software and physical components (e.g., sensors, actuators, external memory, peripherals like SPI, I2C, UART).

• Automation Development: Design, develop, and maintain automated test scripts and test harnesses using scripting languages (e.g., Python, Bash) and specialized tools to enhance test coverage and efficiency, particularly for regression testing.

• Defect Management: Identify, document, track, and verify resolution of software defects using bug tracking systems. Provide clear and concise bug reports with steps to reproduce and relevant logs.

• Root Cause Analysis: Collaborate with firmware developers to perform in-depth root cause analysis of defects, often involving debugging on embedded targets using JTAG/SWD, oscilloscopes, logic analyzers, and other hardware debugging tools.

• Performance & Resource Analysis: Monitor and analyze firmware performance metrics (CPU usage, memory footprint, power consumption, boot time, latency) and validate against specified requirements.

• Regression & Release Qualification: Own the regression testing process and contribute significantly to the final release qualification of firmware builds.

• Process Improvement: Champion and contribute to the continuous improvement of firmware development and quality assurance processes, methodologies, and best practices.

QUALIFICATIONS

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field.

• 5 years of experience in Software Quality Assurance, with a minimum of 2 years directly focused on firmware or embedded software testing.

• Strong understanding of embedded systems concepts, including microcontrollers/microprocessors, real-time operating systems (RTOS), interrupts, memory management, and common peripheral interfaces (GPIO, I2C, SPI, UART, ADC, DAC, Timers).

• Proficiency in C/C++ for embedded development, with the ability to read, understand, and debug firmware code.

• Experience with scripting languages for test automation (e.g., Python, Bash).

• Hands-on experience with hardware debugging tools such as JTAG/SWD debuggers, oscilloscopes, logic analyzers, and multimeters.

• Familiarity with version control systems (e.g., Git) and bug tracking tools (e.g., Jira, Azure DevOps).

• Experience with test management tools (e.g., TestRail, Zephyr).

• Excellent problem-solving skills, with a methodical and analytical approach to identifying and isolating defects.

PREFERRED QUALIFICATIONS

• Experience with continuous integration/continuous deployment (CI/CD) pipelines for embedded systems.

• Knowledge of networking protocols (TCP/IP)

• Experience with Hardware-in-the-Loop (HIL) testing, simulation, or emulation environments.
