Join to apply for the Senior Software Engineer - Boot Verify role at NinjaOne

Description
About the Role
As a Senior Software Engineer at NinjaOne, you will bring deep expertise in Windows boot processes and systems engineering to strengthen our existing boot verification service. This service validates the integrity of Windows machine image backups by launching them in a hypervisor with a custom virtual disk layer that streams only the blocks accessed during startup. You'll work alongside an established team, contributing advanced knowledge and solving the toughest technical challenges to ensure our platform delivers reliable, high-confidence backup verification at scale.
Location - We are flexible on remote working from home, if you are located in the USA and reside in one of the following states - CA, CO, CT, FL, GA, *IL, KS, ME, MA, NJ, NC, NY, OR, TN, TX, VA, and WA. We have physical offices in Austin, TX and Tampa, FL, if you prefer a hybrid option.
We hire the best software engineers, but experience in our stack can’t hurt: NinjaOne is built on Java, Kotlin, C++, Golang and Postgres; supporting millions of user endpoints and running as a scalable cloud service in AWS. Knowing large-scale datastore bottlenecks, asynchronous application design and client-server architecture will help you.
What You’ll be Doing

• Windows Boot SME (Subject Matter Expert): you are a Windows boot process expert, helping the team diagnose and resolve complex issues that arise during backup verification. Extend and refine our custom virtual block device implementation to optimize I/O efficiency and compatibility with Windows workloads. Guide the team in debugging hard-to-diagnose Windows boot failures, such as BCD errors, driver incompatibilities, or kernel initialization issues. Improve automation, monitoring, and reporting of verification outcomes, with a focus on Windows-specific signals and diagnostics. Investigate and resolve issues with Windows boot failures (e.g., BCD errors, driver incompatibilities, corrupted system files). Document system architecture, design tradeoffs, and operational procedures for Windows boot verification.
• Software Engineering: collaborate with engineers across storage, infrastructure, and product teams to enhance system reliability and integration. Mentor teammates by sharing knowledge of Windows internals, virtualization, and storage systems. Participate in peer code reviews, architecture discussions, and technical decision-making.
• Other duties as needed
  

About You

• Experience diagnosing Windows system failures using logs, crash dumps, and recovery tools.
• Familiarity with block device interfaces, storage protocols, and how Windows accesses disks during startup.
• Strong programming skills in C++
• Python experience will make you a standout candidate.
• Hands-on experience with virtualization, emulation technologies such as: QEMU, KVM, Xen, VMware, and VirtualBox.
• Experience with distributed storage systems, for example S3-compatible object storage; is a strong plus.
• Your knowledge of containerization and orchestration tools such as Docker and Kubernetes for managing isolated workloads.
