Senior ML Software Engineer

Seoul (On-site) • Full-time

  • KOREAN: NOT REQUIRED
  • Machine Learning
  • Python
  • C++
  • AI

AI today is trapped in the hands of the GPU cartel — locked in costly servers, paywalled clouds, and data-hungry monopolies. At ZETIC.ai, we are breaking those chains.

Our platform, MLange, is the world’s first universal on-device AI deployment engine. It lets developers run any AI model, on any hardware, 100x faster — no GPU clusters, no cloud bills, no data leaks. With 5+ billion smartphones, tablets, and edge devices as the new infrastructure, we’re unleashing the sleeping giant of AI.

We exist to give every developer, startup, and nation AI Freedom: • Zero dependency on GPU clouds • Zero infra cost • Zero compromise on privacy • Runs everywhere, offline, instantly

We’re not here to play it safe. We’re here to flip the rules of AI.

We’re looking for a Senior ML Software Engineer ready to take on hard problems and build the backbone of AI Freedom. This is not a “maintenance” role — it’s a chance to design, optimize, and scale the runtime that will power billions of devices worldwide.

If you thrive at the intersection of AI frameworks, system software, and mobile/embedded platforms, and you want your work to break the status quo, this is your calling.

What You’ll Do

  • Architect and optimize runtime components in C++ and Python
  • Deploy AI models on mobile/embedded targets with a laser focus on performance and reliability
  • Collaborate with global AI researchers to bring state-of-the-art models into real-world apps
  • Improve SDK usability so developers can ship AI apps effortlessly
  • Push the limits of benchmarking, profiling, and hardware acceleration across NPUs/GPUs/CPUs

What We’re Looking For

  • Strong proficiency in C/C++ and Python
  • Proven experience in system software or runtime/infra development
  • Hands-on track record of deploying AI models into real-world devices/services
  • Familiarity with mobile (Android/iOS) or embedded systems
  • Experience with model runtimes (ONNX Runtime, TensorRT, CoreML, TFLite, LiteRT etc.) is a plus
  • Deep understanding of performance profiling, memory optimization, hardware acceleration

Bonus Points

  • Built or contributed to cross-platform runtimes or SDKs
  • Experience with heterogeneous hardware acceleration (NPU/GPU/CPU)
  • Previous work in AI infrastructure, edge AI, or model optimization
