Research Engineer Intern, Frontier Speculative Decoding (Summer 2027)

About the Role

Together AI is building the Inference Platform that powers the world's most advanced generative AI models. Our team works on the critical bridge between cutting-edge research and real-world applications, focusing on translating our internal model training research to production-ready deployment for our customers. This involves a deep commitment to data-centric development, meticulous hyperparameter tuning, and rigorous checkpoint evaluation before models ever hit production.

This role will involve understanding customer specific needs and fine-tuning models on our internal data recipe and their proprietary data. The goal is to transform general-purpose models into highly performant, specialized tools that solve real business problems. You will not be training foundation models from scratch but rather focusing on creating highly efficient, specialized models by working with dedicated GPU clusters.

Responsibilities

• Research and prototype new speculator algorithms, experimenting with architectural ideas and data curation to improve accuracy–efficiency tradeoffs in speculative decoding.
• Own a well-scoped project end to end, from data preparation through training and evaluation, with a real path to production.
• Learn how frontier inference systems work in practice, in a fast-paced environment at the cutting edge of generative AI.
• You'll collaborate directly with customers to understand their needs, and work closely with our core inference and Applied ML research teams to integrate your work into the production platform.
• Present your results to the broader team at the end of your internship, with the chance to influence the direction of our speculator work.
• A culture of deep technical ownership where you are empowered to take on and solve challenging problems

Requirements

• Currently pursuing a degree in Computer Science, Electrical Engineering, Information Science, or a related field
• A genuine love for data curation and processing, with a meticulous attention to detail. You believe that great models start with great data.
• Demonstrated ability to perform effective hyperparameter searches and understand the trade-offs involved in tuning models for specific tasks.
• Strong attention-to-detail in evaluating model checkpoints to ensure they meet strict quality, performance, and reliability standards.
• Experience with Python and PyTorch.
• Familiarity with SLURM and/or Kubernetes clusters and experience submitting and managing jobs in a high-performance computing environment.
• Familiarity with modern LLMs and generative models.
• Basic understanding of distributed training frameworks (e.g., FSDP, DeepSpeed).
