[SW] NPU Runtime SW Engineer

Frontier of On-device AI Semiconductors

for Everyone, Everywhere

DEEPX is a leading global tech startup at the forefront of the On-Device AI semiconductor market, built on a dual success formula: Arm’s "ultra-low power technology" and a Qualcomm-style "core patent-based IP portfolio." Having conducted performance tests with over 300 global companies, we are recognized for delivering world-class power efficiency and cost-effectiveness, supported by a formidable portfolio of over 400 AI semiconductor patents worldwide. On the strength of these R&D and commercialization achievements, DEEPX successfully secured large-scale investment in 2024. We are now leading the commercialization of AI across diverse sectors—including smart devices, smart mobility, and industrial automation—within the On-Device AI market, which is projected to reach $10.6 billion by 2030.

Role Overview

The Software Group at DEEPX plays a critical role in enabling customers to easily utilize DEEPX’s world-class AI processor core technologies in various AI-based application products.

The group is responsible for developing a full-stack SDK (DXNN) — from firmware and drivers to the compiler (DX-COM),runtime software (DX-RT), and code design for DNN training frameworks — all necessary for running DEEPX NPUs on customer devices.

The **DEEPX Runtime (DX-RT)**is the CPU-side execution code that enables NPU operations.

The Runtime Software Team:

primarily develops: □Drivers that control NPU execution of AI inference tasks

• Pre-processing modules that handle input data before NPU execution

• Post-processing modules that manage outputs after NPU computation

• Convenient APIs and AI application libraries to support customer integration beyond raw inference

These runtime technologies form the most direct software interface for customers developing real-world applications using DEEPX hardware. If you're passionate about implementing cutting-edge AI algorithms on high-performance, low-power platforms, we invite you to join this meaningful journey at DEEPX.
