Mission:

As a Data Scientist specializing in LLM you will be responsible for developing, implementing and optimizing advanced algorithms, models and capabilities that help our teams (e.g. Field Operations) automate their workloads, e.g. in the context of decision support, mission planning and situational awareness. You will work on a variety of projects that involve understanding, processing and generating human language to solve complex problems and create innovative solutions. The ideal candidate will have a strong background in LLMs, machine learning and data science, with a proven track record of successful projects in these domains.

What will be your responsibilities:

  • Algorithm Development: Design, develop and implement state-of-the-art algorithms and models, within the context of language models.
  • Capability Development: Realize new AI-based capabilities in areas such as decision support, mission planning, workflow automation.
  • Model Training and Optimization: Train and optimize large language models using vast amounts of textual data, ensuring high performance and accuracy.
  • Data Pre-processing: Perform data pre-processing tasks such as tokenization, stemming, lemmatization and normalization to prepare datasets for training and evaluation.
  • Research and Innovation: Stay current with the latest advancements in LLM and Natural Language Processing (NLP) and apply new techniques to improve existing models and develop new solutions.
  • Collaboration: Work closely with data engineers, software developers, product managers and other stakeholders to understand project requirements and deliver effective solutions.
  • Performance Evaluation: Evaluate the performance of models using appropriate metrics and techniques and iteratively improve their accuracy and efficiency.
  • Deployment: Collaborate with engineering teams to deploy models into production environments and ensure their robustness and scalability.
  • Documentation: Maintain comprehensive documentation of models, algorithms and processes for future reference and reproducibility.
