About the Role
We are looking for a Senior Security Engineer to own and enhance the production detection and threat research capabilities of our security platform.
The ideal candidate has hands-on experience building and improving detection systems at scale, understands real-world adversary behavior, and can analyze security signals across logs, network traffic, and telemetry. You will play a key role in strengthening detection capabilities, reducing false positives, and proactively identifying security weaknesses before they are exploited.
Key Responsibilities
Detection Engineering
  • Own and improve production detection architecture.
  • Tune and evaluate statistical anomaly detection models.
  • Improve detection accuracy and reduce false positives.
  • Expand detection coverage as the platform evolves.
  • Harden security models against adversarial attacks.
Red Teaming
  • Perform security assessments and red-team internal security systems.
  • Identify vulnerabilities across security controls, execution layers, and detection mechanisms.
  • Validate security defenses against real-world attack scenarios.
Threat Research
  • Research emerging attack techniques and adversary behavior.
  • Analyze AI-related threats, prompt injection, and model evasion techniques.
  • Translate threat intelligence into actionable detection improvements.
  • Prepare technical findings, advisories, and security documentation.
Security Analysis
  • Analyze packet captures, proxy logs, and production security telemetry.
  • Correlate network and application-level events.
  • Differentiate meaningful security signals from noisy alerts.
Standards Technical Documentation
  • Contribute to technical documentation and security standards.
  • Support regulatory and standards-related technical initiatives.
  • Ensure security controls are auditable, defensible, and technically sound.
Required Skills
Detection Engineering
  • Experience designing, operating, or tuning detection systems at scale.
  • Strong understanding of anomaly detection and security signal quality.
  • Experience reducing false positives and improving detection accuracy.
  • Hands-on experience with production security telemetry.
Security Threat Analysis
  • Strong background in Threat Research or Red Teaming.
  • Experience identifying attack paths and exploitation techniques.
  • Understanding of attacker methodologies and detection evasion.
Network Log Analysis
  • Experience analyzing packet captures and proxy logs.
  • Ability to correlate network and application-level evidence.
  • Strong understanding of security events versus actionable alerts.
AI Security
  • Knowledge of prompt injection risks and AI security.
  • Understanding of security for AI agents, proxies, and automated execution systems.
  • Ability to evaluate security risks in AI-driven environments.
Standards Compliance
  • Experience writing or reviewing technical security documentation.
  • Understanding of auditability, security correctness, and compliance requirements.
Good to Have
  • Published security research or CVE contributions.
  • Experience with NIST, IETF, ISO, W3C, or similar standards bodies.
  • Experience working with enterprise security products.
  • Familiarity with agent identity, revocation mechanisms, and audit frameworks.
  • Background in cloud security, detection engineering, or security infrastructure.
Ideal Candidate Profile
  • 10+ years of experience in Security Engineering, Detection Engineering, Threat Research, or Red Teaming.
  • Proven experience working on large-scale production security systems.
  • Strong analytical and problem-solving skills.
  • Ability to communicate technical concepts effectively to both technical and business stakeholders.
  • Passion for building secure, scalable, and resilient security platforms.
