Join to apply for the Senior Machine Learning Engineer: Post Training & Speculative Decoding role at Groq
Mission: We are seeking a highly skilled Machine Learning Engineer to join our advanced model development team. This role focuses on pre-training, continued training, and post-training of models , with a particular emphasis on draft model optimization for speculative decoding and quantization-aware training (QAT) . The ideal candidate has deep experience with training methodologies, open-weight models, and performance-tuning for inference.
Responsibilities & Outcomes
- Lead pre-training and post-training efforts for draft models tailored to speculative decoding architectures.
- Conduct continued training and post-training of open-weight models for non-draft (standard) inference scenarios.
- Implement and optimize quantization-aware training pipelines to enable low-precision inference with minimal accuracy loss.
- Collaborate with model architecture, inference, and systems teams to evaluate model readiness across training and deployment stages.
- Develop tooling and evaluation metrics for training effectiveness, draft model fidelity, and speculative hit-rate optimization.
- Contribute to experimental designs for novel training regimes and speculative decoding strategies.
Ideal Candidates Have/are
- 5+ years of experience in machine learning, with a strong focus on model training.
- Proven experience with transformer-based architectures (e.g., LLaMA, Mistral, Gemma).
- Deep understanding of speculative decoding and draft model usage.
- Hands-on experience with quantization-aware training, including PyTorch QAT workflows or similar frameworks.
- Familiarity with open-weight foundation models and continued/pre-training techniques.
- Proficient in Python and ML frameworks such as PyTorch, JAX, or TensorFlow.
Preferred Qualifications
- Experience optimizing models for fast inference and sampling in production environments.
- Exposure to distributed training, low-level kernel optimizations, and inference-time system constraints.
- Publications or contributions to open-source ML projects.
Attributes Of a Groqster
