[Production] SLT Engineer

Frontier of ​On-device ​AI ​Semiconductors

for Everyone, ​Everywhere

About DeepX ​Co., ​Ltd.

DEEPX ​is a ​forward-thinking Series D startup ​architecting ​the infrastructure ​for the Physical ​AI era. ​

By ​delivering the ​world’s ​most ​energy-efficient NPU technology, ​we ​are solving the ​critical ​power ​and heat challenges ​of Generative ​AI ​to bring ​super-intelligence to ​every ​device, everywhere.

Our global ​leadership is ​validated by our record-breaking recognition as a multi-year CES Innovation Award honoree (2024 & 2026) and being named the 2024 Frost & Sullivan Company of the Year in the NPU sector. With an enterprise value approaching 1 trillion KRW, DEEPX offers a unique pre-IPO

opportunity to join a market leader defining the new industry standard for the $70B AI semiconductor market.

We are currently scaling toward mass production of our flagship DX-M1 (Samsung 5nm) with over 50 global projects scheduled, while engineering next-generation 2nm solutions to support 100B parameter Large Language Models (LLM) at the edge. ☞ Link

Responsibilities

□ SLT HW/SW Test System Setup & Operation: Establish and operate HW infrastructure (e.g., SLT boards, sockets) and develop/maintain test SW & scripts (firmware, drivers, test scenarios) for mass production testing of AI semiconductors.

□ Mass Production Test Scenario & Program Development: Develop SLT test protocols, workload execution programs, and automated test sequences simulating actual HW and customer-use environments (Mission Mode).

□ Mass Production Yield Management & HW/SW Debugging: Set up SLT in OSATs and production lines; improve yields through Failure Analysis (FA) and cross-debugging across HW (SI/PI, Power, Thermal) and SW (OS, drivers, FW).

□ Reliability & Performance Verification: Validate HW/SW interaction under environmental testing (HTOL, ESD, etc.) and real-world workload conditions.

□ Collaboration & Vendor Management: Drive technical discussions with OSATs, board/socket vendors, and internal SW engineering teams, while managing documentation for mass production transfer.

Qualifications

□ Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, Instrumentation/Control Engineering, or a related field.

□ Minimum 3+ years of experience in SLT system setup, ATE development, or embedded system (HW+SW) verification/mass production.

□ HW Skills: Understanding of schematics and PCB artworks, board-level debugging using measurement equipment, and solid grasp of HW interfaces (PCIe, LPDDR, etc.).

□ SW Skills: Proficiency in writing and modifying embedded SW, drivers, or test scripts in C/C++, Python, and Linux environments.

□ Ability to travel internationally (e.g., OSAT visits) and demonstrate strong, flexible communication skills with external vendors and internal teams.

Preferred Qualifications

□ Hands-on experience with mass production SLT for AI semiconductors, SoCs, or PCIe-based systems.

□ Experience in Linux kernel, bootloader, driver development, and debugging.

□ Experience in high-speed interface (PCIe, LPDDR, etc.) SI/PI analysis and reliability evaluation.

□ Experience in OSAT and semiconductor back-end assembly/test production line automation and infrastructure setup.

□ Exceptional Root Cause Analysis (RCA) capability for complex issues occurring at the HW/SW boundary.
