ML Engineer

March 3, 2025
Full-Time
About the role

We are looking for early members of our research team. As an ML Engineer, you will be responsible for designing and deploying large-scale systems, from data infrastructure to new model architectures, to build Large Audio Models. You will have the opportunity to build infrastructure to manage large-scale datasets, develop tools for data processing and understanding, and innovate the interaction between machine learning and data.


What you’ll do
  • Lead engineering projects for data collection and management.
  • Build tools and models to visualize, evaluate, and filter datasets.
  • Scale machine learning models developed by internal researchers to 7B+ parameters.
  • Develop optimization techniques for distributed parallel systems.
  • Optimize inference speed for large-scale models.
  • Implement models and systems efficiently for data processing, training, inference, and deployment.
What you’ll need
  • Proficiency in Python.
  • Experience developing machine learning models using JAX, PyTorch, or TensorFlow.
  • Familiarity with concepts like DDP, FSDP, Tensor Parallel, and experience writing and optimizing highly parallel and distributed PyTorch code.
  • Experience implementing fundamental machine learning models from scratch, such as Transformer, VAE, and Denoising Diffusion models.
Nice to Have
  • Experience with low-level machine learning optimization, such as writing CUDA kernel code.
  • Experience in large-scale data management.
  • Experience pretraining 7B+ ML models.
  • Familiarity with Kubernetes and Docker.
  • Experience with multi-node distributed training.
About OptimizerAI

At OptimizerAI, we are building world-class audio foundation models essential for all creative works. We believe that many creative works can become more accessible and of higher quality through AI foundation models. However, while much attention has been given to visual effects, the equally important auditory effects have not received as much focus. We are revolutionizing the world of audio by creating an audio model that breathes sound into all soundless creations.

Our first product, a SoundFX foundation model, quickly gained global traction, attracting creators and major game companies like Krafton and Roblox. A short demo video on Twitter (X) sparked widespread organic sharing, rapidly growing our user base without marketing. Within just a few months, we raised a pre-seed round from a16z Speedrun and Krew Capital, reflecting strong confidence in our vision.
