Résumé du poste

Arlin Systems is seeking a Senior Cybersecurity Engineer to design and build autonomous threat detection agents for the Sentinel platform. You will create intelligent agents that monitor, correlate, and autonomously respond to security events across cloud, on-premises, and edge environments.

You will work on threat intelligence integration, anomaly detection, and autonomous workflows while mentoring junior engineers and contributing to documentation.

Qualifications

• 5+ years in cybersecurity or security engineering.
• Expertise in threat detection, security architecture, or incident response.
• Knowledge of modern security challenges incl. threats, threat intel, compliance.
• Experience with SIEM, IDS/IPS, or security analytics.
• Programming in Python, Go, Rust, or C++.
• Cloud security experience (AWS, GCP, or Azure).

Responsabilités

• Design autonomous threat detection agents for Sentinel.
• Build threat correlation and analysis systems that operate autonomously.
• Contribute to Sentinel's threat intelligence and learning capabilities.
• Collaborate with teams to integrate Sentinel into customer environments.
• Participate in security reviews and threat modeling for agentic systems.
• Mentor junior engineers and contribute to technical documentation.

Description du poste

Location: Remote | Experience Level: Senior (5+ years)

Build the next generation of autonomous threat detection systems. You'll design and develop Sentinel—our agentic threat detection platform that autonomously monitors, analyzes, and responds to threats in real-time.

About the Role

Sentinel is redefining security by replacing reactive detection with proactive, autonomous agents. As a Senior Cybersecurity Engineer, you'll architect and build intelligent security agents that learn from threats, correlate events, and make autonomous response decisions without human intervention.

You'll work on:

• Autonomous threat detection agents - Design agents that continuously monitor and analyze security events
• Intelligent anomaly detection - Build systems that recognize threats through behavioral analysis and pattern correlation
• Autonomous response workflows - Create decision-making frameworks for autonomous threat response
• Threat intelligence integration - Build agent systems that learn from threat data and improve autonomously

About You

Required:

• 5+ years of professional cybersecurity or security engineering experience
• Deep expertise in threat detection, security architecture, or incident response
• Strong understanding of modern security challenges (advanced threats, threat intelligence, compliance)
• Experience with SIEM systems, IDS/IPS, or security analytics platforms
• Proficiency in at least one programming language (Python, Go, Rust, or C++)
• Experience with cloud security (AWS, GCP, or Azure)

Nice to Have:

• Experience with machine learning or anomaly detection systems
• Background in autonomous systems or agent-based architecture
• Contributions to open-source security projects
• Knowledge of threat intelligence platforms or threat hunting frameworks

What We're Looking For

• Deep technical problem-solving skills with a focus on autonomous security systems
• Experience designing systems that make intelligent decisions without human intervention
• Ability to work across multiple domains (cloud, on-premises, edge environments)
• Strong communication skills to explain complex security concepts to non-security teams
• Passion for building production-grade systems that operate reliably at scale

Responsibilities

• Design and develop autonomous threat detection agents for Sentinel
• Build threat correlation and analysis systems that operate autonomously
• Contribute to Sentinel's threat intelligence and learning capabilities
• Collaborate with teams to integrate Sentinel into customer environments
• Participate in security reviews and threat modeling for our agentic systems
• Mentor junior engineers and contribute to technical documentation

• Work on cutting-edge agentic security - Build systems that represent the future of cybersecurity
• Autonomous systems at scale - Design security agents deployed globally
• Technical depth - Solve challenging problems in threat detection and autonomous response
• Ownership - Own significant portions of the Sentinel platform
• Remote-friendly - Work from anywhere with a collaborative, distributed team
• Learning opportunities - Stay at the forefront of autonomous security systems and AI
• Competitive salary commensurate with experience
• Equity in Arlin Systems
• Remote work flexibility
• Annual discretionary PTO
