Staff Software Engineer - EDR Agent (Go)

Huntress is a remote-first team working to make enterprise-grade cybersecurity accessible to businesses of all sizes. They are seeking a Staff Software Engineer to set the technical direction for their endpoint agents, focusing on high-performance development in Go and collaboration with cross-functional teams.

Responsibilities:

• Design, develop, and maintain high-performance agents using Go
• Apply a strong understanding of operating systems: processes, memory, file systems, syscalls, the user/kernel boundary to extract telemetry and manage state efficiently, and be able to pick up new OS-specific paradigms as we expand
• Integrate our endpoint application with our backend SaaS web application's REST APIs to manage state and provide information used for threat hunting, with particular attention to low resource usage on endpoints
• Build and maintain the concurrent, performance-sensitive core of the endpoint agent, and set the standard for what good Go looks like here
• Use AI tools to move faster and define how the team does so responsibly, what gets AI-assisted, how AI-generated code is reviewed and validated, and where the line sits, given that the endpoint agent runs with high privilege on customer machines and ships to millions of hosts
• Collaborate with cross-functional teams to align development efforts with company goals
• Mentor and coach junior engineers, guiding best software development and cybersecurity practices
• Explain low-level OS behavior and architectural tradeoffs clearly to both technical and non-technical stakeholders across Product, Threat Operations, and leadership
• Collaborate with DevOps to use our end-to-end testing framework to test our agent and its interactions with our web portal

Requirements:

• Cybersecurity experience or a willingness to learn
• 5+ years of hands-on experience writing idiomatic, concurrent, well-tested, and tuned for performance production Go code
• A strong grasp of OS internals, memory management, file systems, process lifecycles, and the user/kernel boundary
• Real depth in at least one major OS ecosystem (Windows internals, macOS/Darwin, or Linux) and a track record of ramping quickly on unfamiliar OS internals and APIs
• Proven track record of developing software for distributed systems, ensuring scalability, performance, and reliability
• Experience using AI coding agents to accelerate development
• Ability to coach or mentor junior engineers, helping them grow and excel in their roles
• Experience or familiarity with EDR or EPP systems is a plus
