Role Overview
As a Principal Software Engineer, you will drive the design and evolution of core systems within a cloud-managed virtualization platform. Your work will center on low-level infrastructure that powers virtual desktop delivery, with a focus on performance, reliability, and deep system integration across firmware, kernel, and cloud environments.
Key Responsibilities
- Develop and maintain streaming drivers for networking and storage, optimizing data flow at the system level.
- Implement custom miniport drivers to enable early-stage Windows boot disk access, ensuring seamless OS initialization.
- Design high-throughput data paths using NDIS and STORPORT to bridge network input with disk I/O operations.
- Create UEFI firmware applications using Tiano Core and EDK II to manage pre-boot execution and hardware initialization.
- Build and troubleshoot network boot pipelines leveraging PXE, TFTP, DHCP, and DNS for bare-metal and virtual provisioning.
- Lead development of VHD/VHDX stack implementations, supporting both kernel and user-mode operations with high efficiency.
- Engineer write-cache mechanisms using differencing disks to enhance performance in non-persistent environments.
- Design storage filter drivers to redirect I/O traffic intelligently and improve system responsiveness.
- Develop system utilities for configuring boot media and maintain core C++ SDKs and PowerShell libraries.
Required Qualifications
- 12–15 years of systems programming in C/C++, or 8 years with a Master’s degree, or 5 with a PhD.
- Deep proficiency in low-level programming, memory management, and performance optimization in constrained environments.
- Proven experience developing kernel-mode drivers or core OS components.
- Familiarity with UEFI/BIOS and pre-boot application development.
- Leadership in technical strategy within large, agile software teams.
- Understanding of secure boot, trusted execution, and cryptographic code signing.
- Ability to communicate complex technical constraints to non-technical stakeholders.
Preferred Skills
- Experience debugging network and storage I/O paths, including miniport and filter drivers.
- Proficiency with kernel debuggers to resolve crashes, race conditions, and bottlenecks.
- Strong grasp of interrupt handling, memory management, and I/O lifecycle.
- Knowledge of automated provisioning and pre-boot networking protocols.
- Familiarity with virtualized storage formats, snapshots, and metadata structures.
- Ability to integrate solutions across user-mode, kernel-mode, and system libraries.
