The Senior Security Engineer will design detection logic, investigate alerts, automate responses, and collaborate on threat detection with team members. Responsibilities include triaging alerts, writing detection code, and defining best practices for detection frameworks.
Description
We're looking for a Senior Security Engineer to join our globally distributed, high-impact security engineering team. You will design and implement detection logic, investigate alerts, and automate response mechanisms. As an early hire, you'll work closely with our platform and AI teams to shape how autonomous threat detection and response is built and delivered at scale.
Responsibilities:
- Lead Investigations: Triage, analyze, and respond to alerts across cloud, endpoint, and network environments with automation-first principles.
- Build Detections: Write detection logic and behavioral rules as code that is clear, testable, and scalable.
- Automate Response Workflows: Develop Go-based automation for enrichment, containment, and remediation playbooks.
- Define Detection-as-Code Practices: Implement a detection and response framework with strong engineering fundamentals (testing, CI/CD, version
- control).
- Collaborate Across Functions: Partner with platform and AI teams to integrate detection logic into the broader Daylight stack.
- Support DFIR: Participate in incident investigations and post-incident reviews; DFIR skills (memory, disk, or cloud forensics) are a strong plus.
- Security Operations Experience: 3+ years in detection engineering, incident response, or blue team roles.
- Automation Mindset: You automate what others manually repeat. Experience building or integrating automated response systems is key.
- Cloud-Native Awareness: Familiarity with detecting and responding to threats in cloud environments (AWS, GCP, or Azure).
- DFIR Skills: Practical experience in digital forensics and incident response — logs, memory, containers, cloud.
- Threat-Informed Thinking: Comfort with attacker tactics and techniques (MITRE ATT&CK, behavioral detection, threat modeling).

What you need to know about the Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
- Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
- Key Industries: Artificial intelligence, adtech, media, software, game development
- Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
- Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
- Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
