• Work across Windows and Linux environments
• Partner with hardware, firmware, and platform engineers on architecture and design reviews
• Integrate solutions into CI/CD pipelines to ensure quality and long‑term maintainability
• Document designs, decisions, and technical tradeoffs

• Strong C++ development background (Python a plus)
• Experience building software that interfaces with or supports server or data center hardware
• Proven ability to debug complex, multi‑layered systems
• Experience with CI/CD pipelines (Azure DevOps preferred)

Preferred

• Experience with Rust
• Open‑source contributions
• Systems, infrastructure, or low‑level software background
