About the Role

Lambda Security protects valuable digital assets including training data, model weights, and sensitive inputs for AI models. As a hands-on technical expert on the Detection & Response team, you will ensure Lambda is the safest place to build with AI by catching security issues in real-time while enabling hypergrowth velocity. Your focus will be on automation, threat hunting, detection engineering, and incident response capability building, transforming reactive security operations into a proactive threat management engine. You will implement enterprise-grade detection capabilities, automate incident response workflows, and harden infrastructure. You will pioneer AI-powered security solutions using internal LLMs, maintaining 24/7 operational resilience through automation, rapid incident investigation, and advancing D&R capabilities.

Responsibilities

Design, build, and maintain robust detection rules, signatures, and behavioral analytics across Lambda's cloud, bare-metal, and internal infrastructure
Conduct proactive threat hunting operations to uncover hidden threat actors, novel attack vectors, and zero-day vulnerabilities across multi-cloud and AI workloads
Develop custom detection logic and playbooks as code, eliminating manual triage toil and reducing time-to-detect and time-to-respond
Pioneer AI-powered detection and investigation workflows leveraging internal LLM infrastructure to automate log analysis and threat intelligence context
Lead technical incident response investigations for complex security events, performing deep-dive forensic analysis, root-cause identification, and containment
Architect automated response capabilities and orchestration pipelines (SOAR) to programmatically isolate compromised assets and revoke compromised credentials
Partner with Platform and Infrastructure engineering teams to harden systems, build security instrumentation, and ensure telemetry coverage across all services
Participate in an engineering on-call rotation to maintain 24/7 operational readiness and rapid incident containment
Conduct post-incident reviews to extract technical learnings, drive root-cause remediation, and prevent recurring incidents
Mentor junior and mid-level security engineers, sharing technical domain expertise and promoting best practices in detection engineering and automation

Requirements

5+ years of hands-on security engineering experience specializing in detection engineering, threat hunting, or digital forensics and incident response (DFIR)
Strong programming/scripting proficiency (e.g., Python, Go, Rust, or Bash) with a track record of building automated security tools and pipelines
Deep technical knowledge of cloud infrastructure security (AWS/GCP), Linux system internals, container runtime security, and network telemetry
Clear understanding of the unique requirements of securing a cloud infrastructure provider
Proven experience writing detection rules (SIEM, YARA, Sigma, Falco, or EDR queries) and managing detections through software development best practices
Hands-on experience conducting forensic investigations and triaging complex, multi-stage attacks across cloud environments
Strong technical communication skills with the ability to document complex vulnerabilities, incident post-mortems, and architectural designs clearly
Thrives in high-ambiguity environments where you must build structure while executing at startup pace
