Senior Engineer

NVIDIA is looking for a Senior Engineer to drive the performance modeling, evaluation, and post-training of large language models specialized in code generation, software engineering, and agentic coding tasks.

In this role, you will work at the intersection of model training, inference optimization, and empirical analysis to improve coding model capabilities, efficiency, reliability, and real-world developer productivity.

Responsibilities:

• Develop meticulous frameworks to measure and analyze coding model performance across code generation, debugging, code completion, repository-level reasoning, and multi-step software engineering tasks.
• Develop, and optimize post-training pipelines for coding models, including supervised fine-tuning (SFT), preference optimization, reinforcement learning (RL), and outcome-based or process-based reward modeling.
• Analyze benchmark results, training dynamics, failure modes, and model behaviors to find opportunities for improvement.
• Improve model performance on sophisticated coding tasks through targeted training interventions, reward design, curriculum development, and iterative error analysis.
• Build scalable, reproducible infrastructure for training experiments, evaluation pipelines, and model performance analysis.

Requirements:

• Bachelor's degree (or equivalent experience) in Computer Science or AI with 12+ years of meaningful work experience.
• Excellent programming skills in Python and strong understanding of large language models, transformer architectures, and the training and evaluation of generative models.
• Foundational understanding of reinforcement learning algorithms and implementation, including MDPs, policies, and reward design.
• Deep understanding of software engineering fundamentals, code generation, automated testing, and program correctness.
• Proven track record to lead model development life cycles, including dataset versioning, experiment tracking, and evaluation pipelines.

Nice to Have:

• Experience training or post-training state-of-the-art coding models or models designed for software engineering agents.
• Experience with execution-based rewards, verifiable rewards, reward hacking mitigation, and automated code evaluation.
• Familiarity with coding benchmarks and evaluation environments such as SWE-bench.

NVIDIA offers highly competitive salaries and a comprehensive benefits package. The base salary range is 224,000 USD - 356,500 USD for Level 5, and 272,000 USD - 431,250 USD for Level 6.
