Job Description


The Foundation Models Lab at ServiceNow Research builds the foundation for ServiceNow’s bespoke generative AI solutions, specifically tailored to meet the unique demands of our enterprise environment. Renowned for co-leading the BigCode project and releasing influential models like StarCoder and StarCoder 2, along with datasets such as the Stack and the Stack v2, our lab is now dedicated to strategic pretraining of foundation models for enterprise applications. Our mission extends beyond mere training; we aim to holistically design large language models considering their entire lifecycle. This includes curating training data to meet specific performance expectations, maximizing training efficiency, and, crucially, optimizing models for fast and cost-effective inference. By doing so, we ensure that our AI models are robust, efficient, and ready for further refinement and integration into ServiceNow’s broader AI ecosystem.


We are seeking a Senior Staff Research Developer with deep expertise in AI research, particularly focused on planning and executing experiments that push the boundaries of AI training and model efficiency. In this role, you will:

  • Lead experimental research projects that optimize our large language models, focusing on reducing inference latency, integrating mixture-of-experts and related techniques, and applying scaling laws to maximize training efficiency.
  • Innovate on data curation and utilization strategies to enhance model training, developing sophisticated filtering and selection techniques that improve data quality and directly boost downstream performance.
  • Publish findings and contribute to the scientific community through impactful papers and presentations, thereby establishing ServiceNow as a leader in AI research.
  • Work autonomously, demonstrating resoluteness and resourcefulness in tackling complex research challenges, and continuously exploring new methodologies to refine our AI models.
  • Help the team deeply understand the contexts and purposes in which the models will be used to ensure their adequacy and maximize their impact.
  • Mentor other team members and facilitate effective collaboration among coworkers & cross-functionally.


To be successful in this role you have:

  • A Ph.D. in computer science, engineering, or a related field, with five years experience in AI research, or a M.Sc. with eight years experience.
  • Demonstrated experience in conducting significant research projects, with a focus on experimental design, data analysis, and hypothesis testing.
  • Profound understanding of the data processes involved in pretraining large language models, with experience in optimizing these processes for large-scale environments.
  • Expertise in deep learning frameworks and computational models, with a solid foundation in the principles underlying model scalability and efficiency.
  • Strong proficiency in Python and major deep learning frameworks like PyTorch or JAX.
  • Strong problem-solving skills and independence in managing complex research activities.
  • Excellent communication skills, capable of articulating complex technical details and collaborating effectively across multidisciplinary teams.

What We Offer

  • A role at the forefront of AI research and development with opportunities to impact enterprise-level solutions.
  • Collaboration with a strong team of experts dedicated to pushing the boundaries of AI technology.
  • A dynamic and supportive work environment that fosters innovation and growth.
