Job description

About the Role: As Senior Software Engineer, you will be making technical direction and architectural decisions for the platform. This role requires a mix of software development and ML Ops practices. The right candidate will bring deep experience building, shipping, and supporting mission-critical services across the full data stack. Experience in the national security field is a strong plus to best understand Customer requirements and how that will drive the product roadmap. We are an AI-native engineering team. We expect every engineer to leverage LLMs and AI tooling as a core part of how they design, build, ship, and debug software as an integral, daily extension of their workflow.

Clearance Requirement: An active U.S. Government Secret clearance is not required. Candidates must be U.S. citizens and be eligible to maintain and upgrade clearances as the role requires. Candidates need to be excited to work for the Defense and Intel Communities, and to apply AI to real applications for Government., We are an AI-native engineering team. We expect every engineer to leverage LLMs and AI tooling as a core part of how they design, build, ship, and operate agentic systems that turn frontier-model capability into mission outcomes.

  • Mission-Driven: You are excited by how AI enables better solutions to hard, long-standing problems like data sharing, and you want to see that work deployed in environments where it matters.

Bonus Points:

  • Vector store deployment at enterprise scale.
  • Infrastructure management (Docker, Kubernetes, AWS, GCP, On-Premise).
  • Encryption, authentication, DevOps, or SRE expertise.
  • Production experience launching agentic services leveraging LLMs, embeddings, and inference.
