MEANINGFUL WORK AND PERSONAL IMPACT
This role designs, builds, and supports complex software systems that directly enable mission success. You will:
Architect full end‑to‑end software systems and services — defining structure, interfaces, technology choices, and making thoughtful trade-offs based on mission needs and technical constraints.
Research, design, develop, and modify enterprise software throughout the full software development lifecycle.
Create architecture diagrams, design documents, and technical patterns that guide other engineers and support long-term scalability and maintainability.
Write production-grade software primarily in Go and Rust, plus shell/Bash for automation and supporting tools. Develop automated tests to ensure ongoing reliability.
Contribute to front-end development in TypeScript and React when needed.
Use AI-assisted and agentic coding tools (e.g., Claude Code, OpenAI Codex) as part of daily development — analyzing codebases, troubleshooting production systems, and accelerating problem-solving — while applying good judgment about when human review is required.
Package, build, and deploy containerized applications in modern orchestrated, GitOps-driven environments. Plan, manage, and monitor deployments, owning the reliability of the software you ship.
Build internal tools, CLIs, and APIs that streamline development, build, and deployment workflows.
Work across the entire stack — application code, container runtime, OS, and kernel — to diagnose issues and deliver solutions within distributed, mission-critical systems.
