Tech Lead Engineer - Device Agent

We're looking for a Tech Lead Engineer to drive the technical strategy for our cross-platform endpoint agent - built in C#/.NET and hardened for production across macOS, Windows, and Linux. You'll own features end to end across a managed fleet of enterprise devices, stay hands-on writing code, and raise the technical bar for a distributed engineering team. This role also means setting the standard for how the team uses AI coding agents responsibly - fast, but production-grade.Responsibilities:Drive the technical strategy for our cross-platform endpoint agent, focusing on C#/.NET core logic while ensuring production readiness across macOS, Windows, and Linux.Provide technical leadership to a distributed team of engineers, raising technical expertise and engineering practices across the organization.Own features from discovery to delivery, solving complex domain problems across a managed fleet of enterprise devices.Maintain a hands-on approach by writing code and mentoring engineers to elevate the organization's technical capabilities.Architect the agent using C# and platform-specific extensions, ensuring performant integration with each operating system's security frameworks.Own high-impact technical decisions that balance velocity, security, and reliability.Deliver maintainable features supported by comprehensive testing, metrics, and monitoring.Shape the agent roadmap and ensure resilient production systems in collaboration with cross-functional leadership.Participate in design and code reviews to maintain high engineering standards.Champion AI-assisted engineering across the team - set the bar for how coding agents accelerate delivery, and establish the practices and guardrails that keep output production-grade.Requirements: Requirements:8+ years building device agent software at enterprise scale, with a track record of leading complex technical initiatives end-to-end and mentoring engineers.Deep expertise in endpoint agent development (EDR/XDR), OS internals, and security distribution (code signing, notarization/equivalent, MDM deployment), including reverse engineering and platform-specific facilities (eBPF on Linux; WFP, minifilters, kernel drivers on Windows).High proficiency in C#/.NET (including P/Invoke); native systems languages (Swift, C/C++) are a strong plus for platform-specific extensions, as is PowerShell, shell scripting, or Python.Experience delivering in Agile, CI/CD environments; large-scale cloud services experience is a plus.Strong collaboration, pragmatism, and problem-solving in high-velocity, fast-changing settings.Practical experience using AI coding agents/assistants (e.g.
