Job Summary

We’re hiring a Senior Staff Software Engineer to lead the design, development, and quality engineering of Kaseya’s endpoint management agents across Windows, macOS, Linux, and mobile platforms. This is not a traditional QA automation role. You will write production software, own critical agent capabilities, and build the automated frameworks that validate them at system level. You will influence architecture and engineering standards across teams while remaining hands-on in implementation, debugging, release readiness, and production support.

Roles & Responsibilities

Define architecture and technical direction for endpoint agent capabilities, testability, and system-level validation across supported platforms

Design, build, and operate production agent features using C# and .NET, including monitoring, automation, patching, inventory collection, remote actions, scripting, and device management

Own critical endpoint capabilities from technical design and implementation through automated validation, deployment, monitoring, and production support

Design reusable automation frameworks, test infrastructure, and validation tooling for Windows, macOS, Linux, and mobile environments

Build automated coverage for installation, upgrades, rollback, policy execution, disconnected operation, recovery, performance, security, and operating system compatibility

Improve agent reliability through testability, diagnostics, telemetry, observability, performance analysis, and automated failure detection

Lead investigations into complex customer and production issues, complete root-cause analysis, and implement preventative engineering solutions

Lead design and code reviews, mentor Senior and Staff Engineers, and establish effective practices for AI-assisted development and testing

Required Qualifications

10+ years of software engineering experience building production system software, endpoint applications, platform services, or related products

6+ years of experience developing and operating production applications or services using C# and .NET

Experience developing software that integrates with Windows capabilities such as Win32 APIs, Windows Services, WMI, Registry operations, process and thread management, or operating system security models

Experience designing and maintaining automated test frameworks integrated into CI/CD pipelines for functional, integration, regression, resiliency, or system-level validation

Experience leading the architecture and delivery of technical initiatives involving multiple engineers or teams, with ownership through deployment and production support

Preferred Qualifications

Experience building RMM, UEM, EDR, XDR, endpoint security, or device management products

Experience developing cross-platform agents or systems software across Windows, macOS, Linux, or mobile platforms

Experience developing production software using C, C++, Rust, Go, or similar systems programming languages

Experience with Microsoft Intune, Apple MDM, Android Enterprise, or Linux device management platforms

Experience with PowerShell, Bash, Python, AppleScript, virtualization, or automated device provisioning environments

Experience using AI-assisted development tools for codebase exploration, implementation, test generation, debugging, refactoring, documentation, or coverage analysis
