Responsibilities

Fine-tune, adapt, and distill open-weight models for software-engineering-related tasks.
Own the model experimentation loop, including dataset curation, training pipelines, architecture experiments, and technique evaluation.
Build evaluations on real software engineering tasks to establish baselines, expose failure modes, and measure genuine improvements.
Collaborate with platform engineers to identify model limitations and ship capabilities into production.
Experiment with supervised fine-tuning, synthetic data, preference optimization, and reinforcement learning.
Deliver customer-focused applications that reduce reliance on expensive frontier-model inference.
Establish datasets, evaluations, and research practices for future in-house model training.

Demonstrated hands-on experience training, fine-tuning, or adapting language models using model weights rather than only model APIs or prompts.
Strong software engineering fundamentals, including building reliable training pipelines, debugging complex systems, and writing reusable code.
Strong Python and PyTorch skills, with working knowledge of transformer architectures, tokenization, and language-model training.
A demonstrated model-engineering project, such as a fine-tuned model, original training approach, or meaningful open-source ML contribution.
Preferred qualifications include experience with code generation, program synthesis, repository understanding, synthetic data, distillation, quantization, preference optimization, reinforcement learning, model development, applied ML research, or reproducing significant research results.
