Agent Engineer (Linux Focused)
About the position
What we do:
Halcyon is the industry’s first dedicated, adaptive security platform that combines multiple proprietary advanced prevention engines along with AI models focused specifically on stopping ransomware.
Who we are:
Halcyon was formed in 2021 by a team of cyber industry veterans after battling the scourge of ransomware (and advanced threats) for years at some of the largest global security vendors. Comprised of leaders from Cylance (now Blackberry), Accuvant (now Optiv), Fireye and ISS X-Force (now IBM), Halcyon is focused on building products and solutions for mid-market and enterprise customers.
As a remote-native, completely distributed global team, we recognize great talent can exist anywhere. We invite you to apply to a job you’re interested in and we'll work a plan to meet your needs.
The Role
Responsibilities
Develop Cross-Platform Agent Core: Write production-quality Rust code that transforms messages, processes data, communicates over IPC channels, and interfaces with components written in different languages including Web API integration.
Design and Build Agent Functionality: Implement core agent operations including data processing pipelines, inter-component communication, and system integration for endpoint agents across Linux, Windows, and macOS platforms.
Linux Platform Development: Contribute to Linux-specific agent components, leveraging knowledge of Linux internals, system calls, and platform-specific APIs to build reliable, performant functionality.
Customer Escalation Ownership: Serve as a primary action point for engineering escalations from the Customer Success team. Analyze logs, crash dumps, diagnostics, and field data to triage customer-reported issues, identify root causes, and drive timely resolutions. This includes communicating findings back to CS and coordinating fixes across releases.
Debugging and Optimization: Use logs, debuggers, and profiling tools to analyze performance, diagnose issues, and ensure correct behavior across all supported platforms.
Test and Maintain Code Quality: Write unit and integration tests for your code, adhering to consistent coding style guidelines and overall product architecture.
Cross-Functional Collaboration: Work closely with customer support, product management, and engineering teams to resolve customer issues and improve product quality. Communicate effectively with other developers to ensure components integrate well within the overall product architecture.
