Staff Software Engineer - EDR Agent (Go)

Title: Staff Software Engineer, EDR Agent (Go)

Reports to: Engineering Manager

Location: Remote US

Compensation Range: $200,000 to $220,000 base plus bonus and equity

What We Do:

Cybercrime is growing, and more businesses are getting hit by threats that used to target only the biggest organizations. That pushes defenders like us to operate at the highest level, and it deepens our need for good people who want to make a meaningful impact.

Founded in 2015 by former NSA cyber operators, Huntress is a remote-first team working to make enterprise-grade cybersecurity accessible to businesses of all sizes. We work closely with security teams and service providers protecting complex environments, often without the time or headcount to handle it all. That’s why we build our technology in-house and back it with a ²⁴⁄₇ human-led Security Operations Center (SOC). As a result, our platform is never disconnected from the experts who manage it, ensuring our customers’ protection.

Huntress now secures more than 5M endpoints and 11M identities worldwide. Those numbers keep growing because more businesses rely on us to help carry the load and operate with more confidence. Every day, you can see that commitment in how we stand with our customers and how we show up for each other.

What You’ll Do:

The Huntress team is looking for a Staff Software Engineer to set the technical direction for our endpoint agents that run on every protected host and feed threat-hunting signals back to our platform. Today our agents run on Windows, macOS, and Linux. This is a small, fast-moving product team, so your leverage comes as much from the patterns you set and the engineers you level up as from the code you write yourself.

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.

What You Bring To The Team:

• 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) an…
