Roles & 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 abstractions for process management, networking, filesystem access, services, and device operations.
• Build secure communication between endpoint agents and backend platform services using technologies such as TLS, WebSockets, gRPC, or MQTT.
• Improve agent performance, concurrency, resource usage, reliability, security, and upgrade behaviour.
• Own critical components from technical design and implementation through automated testing, deployment, troubleshooting, and production support.
• Lead technical design reviews, code reviews, and architecture discussions involving endpoint and backend platform teams.
• Mentor engineers and establish reusable patterns for cross-platform systems development and AI-assisted engineering workflows.

Required Qualifications

• 7+ 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.
• Experience developing against operating system APIs such as Win32, POSIX, or native macOS frameworks.
• Experience leading the design and delivery of networked or distributed systems using technologies such as TLS, WebSockets, gRPC, or MQTT.

Preferred Qualifications

• Experience building RMM, UEM, EDR, endpoint security, or device-management products.
• Experience with threading, concurrency, process management, and performance-sensitive systems.
• Experience with AWS.
