Job Description:

The Leidos Innovation Center (LInC) Advanced Analytics team has an opening for a Machine Learning Research Scientist with a background in deep learning to integrate, adapt, and extend novel capabilities to address the customer’s research challenges in competitive contract and internal research and development (R&D) programs (basic and applied).   Candidates with a deep technical background in multimodal machine learning, few-shot / one-shot / zero-shot learning, semi-supervised / self-supervised / weakly-supervised learning, learning on graphs, or recommender systems are strongly encouraged to apply.

Position summary:

We are looking for a scientist with a specialization in one of the program’s research focus areas to work with PhD-level peers to develop and implement approaches and solutions for contract research and development projects. The innovative technical approaches and solutions delivered to customers that advance the state of the art in the research while addressing long-term problems of importance to national security.    The ideal candidate will have a proven track record of supporting all aspects of the program life cycle: supporting business development through the design of new research concepts and topics; writing technical approaches and plans as part of the proposal process; leading multi-discipline project teams and supporting project execution objectives; and transition of impactful, novel capabilities to stakeholders and the communities of practice at the project’s conclusion.

Job Responsibilities:

  • Independently influence the development of approaches and solutions that address highly complex research challenges as well as partner in a team environment across organizations.
  • Independently design and undertake new applications of research as well as partner in a team environment across organizations.
  • Develop topics for novel and innovative R&D approaches to solving program challenges and work with potential sponsors (customers or internal champions) to secure funding for new research efforts based on those topics.
  • Perform metrics-based evaluations of new technologies from research organizations to determine potential contributions.
  • Lead teams of fellow researchers, data scientists, data engineers, and software engineers to execute complex R&D programs.
  • Apply machine learning algorithms onto various problem sets

To be successful in this role you need these skills (required):

  • Advanced degree (PhD highly desired) in machine learning, computer science, data science, or a related discipline, such as statistics or applied mathematics.  Typically requires BS degree and 8+ years of prior relevant experience or Masters with 6+ years of prior relevant experience.
