About the Job

Requirements

  • A PhD with 2 or more years, an MS with 6 or more years, or a BS with 8 or more years of relevant experience in computer science, machine learning, computer or electrical engineering, or a related technical discipline.
  • Ability to obtain and maintain a Top Secret security clearance; U.S. citizenship is required by the U.S. government.
  • Experience leading technical development efforts or major workstreams involving software, systems, networking, communications, machine learning, or related domains.
  • Experience translating customer or mission needs into technical requirements, system designs, development and test plans, and integrated software and/or hardware systems.
  • Experience applying state-of-the-art machine-learning methods, including unsupervised and semi-supervised learning techniques, to real-world problems across resource-constrained edge and resource-rich network-core environments.
  • Strong understanding of networking and communications theory across the OSI model.
  • Working knowledge of software design patterns and engineering best practices, including integration, testing, version control, and collaboration tools such as Git, JIRA, and Confluence.
  • Strong written and verbal communication skills.

Responsibilities

  • Lead technical execution of networking, communications, and machine-learning-enabled systems projects from requirements definition through development, integration, testing, demonstration, and transition.
  • Convert customer needs and mission objectives into system requirements, technical architectures, development and test plans, milestones, performance metrics, and acceptance criteria.
  • Lead and mentor multidisciplinary teams of software engineers, systems engineers, researchers, and algorithm developers.
  • Decompose technical problems into actionable tasks; assign work, manage dependencies and risks, and track execution against program objectives.
  • Design and oversee implementation of architectures spanning network protocols, data pipelines, machine-learning models, edge and network-core compute, and external interfaces.
  • Lead design reviews, code reviews, integration activities, technical demonstrations, and customer engagements; ensure delivered systems meet quality, performance, maintainability, testability, security, and reuse standards.
  • Apply state-of-the-art machine-learning and statistical methods to networking, communications, and real-time data challenges in collaboration with customers, mission partners, academic collaborators, and industry partners.

Desired Qualifications

  • Active Top Secret security clearance.
  • Experience developing software in large, multi-party code bases using collaborative engineering practices and modern developer tools, including LLM-enabled coding tools such as Cursor or Codex.
  • Experience developing, integrating, testing, or evaluating software at the PHY, MAC, Network, or Application layers.
  • Experience with 5G system development, testing, evaluation, network management, network security, and/or protocol analysis.
  • Experience supporting technical proposals, customer demonstrations, or capture activities with Department of War or Intelligence Community customers.
