About the role:
Captions is seeking a Machine Learning Engineer to partner closely with our Researchers and bring large-scale multimodal video diffusion models into production. You’ll be responsible for optimizing and deploying state-of-the-art generative models (tens to hundreds of billions of parameters) to deliver low-latency, high-throughput inference at scale. This is a unique opportunity to work on cutting-edge AI—spanning audio-video generation, diffusion architectures, and temporal modeling—and ensure these innovations reach millions of creators worldwide.
Responsibilities:
Requirements:
Technical Expertise
Proven experience deploying deep learning models on GPU-based infrastructure (NVIDIA GPUs, CUDA, TensorRT, etc.).
Strong knowledge of containerization (Docker, Kubernetes) and microservice architectures for ML model serving.
Proficiency with Python and at least one deep learning framework (PyTorch, TensorFlow).
Model Optimization
Familiarity with compression techniques (quantization, pruning, distillation) for large-scale models.
Experience profiling and optimizing model inference (batching, concurrency, hardware utilization).
Infrastructure
Hands-on experience with ML pipeline orchestration (Airflow, Kubeflow, Argo) and automated CI/CD for ML.
Strong grasp of logging, monitoring, and alerting tools (Prometheus, Grafana, etc.) in distributed systems.
Domain Experience
Exposure to diffusion models, multimodal video generation, or large-scale generative architectures.
Experience with distributed training frameworks (FSDP, DeepSpeed, Megatron-LM) or HPC environments.
Benefits:
Comprehensive medical, dental, and vision plans
401K with employer match
Commuter Benefits
Catered lunch multiple days per week
Dinner stipend every night if you're working late and want a bite!
