About this role
Company Overview
Pantheon Data (a Kenific Holding company) is a private, small business based in the Washington, DC, area. Pantheon Data was founded in 2011, initially providing acquisition and supply chain management services to the US Coast Guard. Our service offerings have grown in the past ten years, including infrastructure resiliency, contact center operations, information technology, software engineering, program management, strategic communications, engineering, and cybersecurity. We have also grown our customer base to include commercial clients. The company has used this experience to expand our service offerings to other agencies within the Department of Homeland Security (DHS), the Department of Defense (DoD), and other Federal Civilian Agencies.
Position Overview
We are seeking a hands-on Senior Full Stack Software Engineer (AI-First) to design, build, integrate, and maintain modern software systems that support complex government and commercial technology programs. This is an AI-first engineering role: you will do the majority of your development work through agentic coding harnesses such as Claude Code or OpenAI Codex, writing specifications, directing and supervising coding agents as they work, and rigorously verifying and validating what they produce. You will move comfortably across the stack: user interfaces, APIs, services, databases, cloud-hosted applications, and system integrations.
This is not a role for someone who uses AI as autocomplete or a chat sidebar inside an IDE, and it is not a role for "vibe coding." We need a classically trained software engineer who understands the generated code well enough to review it critically, recognize when an agent is drifting off task, over-engineering a solution, or introducing subtle defects, and step in to correct course, either by redirecting the agent or by writing the code directly when that is the better path. Engineering judgment is the job; agents are how that judgment scales.
