Kaseya; Northern (KY); Hybrid; USD 120,000 - 150,000; Full time

Job summary

Kaseya is seeking a Senior Software Engineer to build and maintain the endpoint agent capabilities powering our next-generation RMM platform. You’ll work hands-on in Rust across Windows, macOS, and Linux, focusing on concurrency, networking, and native OS integrations, collaborating with cross-functional teams.

You will own features end-to-end—from design through production—while improving performance, security, and reliability of the agent and its communications with backend services.

Qualifications

• 5+ years of software engineering experience building systems software, endpoint agents, device-management software, or similar production applications using C, C++, or Rust.
• 2+ years of experience developing production software using Rust, including asynchronous or concurrent programming with Tokio or a similar runtime.
• Experience delivering cross-platform native software across Windows, macOS, and Linux using Win32, POSIX, or native macOS APIs.
• Experience building concurrent or networked software using TLS, WebSockets, gRPC, MQTT, or similar protocols.
• Experience integrating endpoint or systems software with distributed backend services and supporting it in production.

Responsibilities

• Design and build endpoint agent capabilities that run across Windows, macOS, and Linux.
• Develop production systems software using Rust, Tokio, and native operating system APIs.
• Create cross-platform components for process management, networking, filesystem access, services, and device operations.
• Build secure communication between endpoint agents and backend platform services using TLS, WebSockets, gRPC, MQTT, or similar technologies.
• Improve agent performance, concurrency, resource usage, reliability, security, and upgrade behaviour.
• Own features through technical design, implementation, automated testing, release, monitoring, and production support.
• Investigate complex endpoint issues, complete root-cause analysis, and implement long-term corrective improvements.
• Participate in design reviews and code reviews while supporting other engineers through technical guidance and knowledge sharing.
