Remote Prompt Engineering Jobs in California (NOW HIRING)

Role Summary

We are seeking a Threat Detection Engineer to join our security engineering and operations team. In this role, you will develop, test, and optimize high-fidelity detections across modern security data platforms, with a focus on security analytics, automation, and threat detection at scale. You will be expected to bring — and continuously develop — strong AI literacy: designing detection workflows that leverage large language models, anomaly detection, and agentic pipelines, while also understanding and defending against AI-specific attack surfaces.

You should be comfortable writing structured, reusable detection logic, working with infrastructure-as-code (IaC), and integrating behavioral and threat intelligence into detection strategies. You will collaborate closely with incident response, threat intel, and platform engineering teams to ensure resilient, high-quality coverage of modern threat scenarios across cloud and enterprise environments — including threats targeting and exploiting AI systems.

Key Responsibilities

- Design and implement detection logic across SIEM/SOAR platforms, including Splunk, Google Chronicle (SecOps), and Elastic/Logstash.

- Build scalable detection rules, analytics, and anomaly models to detect adversary TTPs aligned with MITRE ATT&CK.

- Develop and maintain detection-as-code using Python and YAML-based rule formats (e.g., Sigma, YARA-L, Kusto, or Lucene).

- Design and evaluate LLM-assisted detection and triage workflows, including prompt engineering for alert enrichment, summarization, and classification.

- Build and maintain AI-augmented detection pipelines: anomaly scoring, embedding-based similarity search, natural language parsing for phishing and social engineering detection, and LLM-based log analysis.

- Apply AI security literacy to identify and detect risks in AI-integrated environments, including prompt injection, model abuse, data exfiltration via LLMs, and shadow AI usage.

- Perform quality assurance and validation of alerts — including AI-generated signals — to minimize false positives and increase signal fidelity.

- Leverage Snowflake and SQL to normalize and query large datasets across multiple telemetry sources, including AI system logs and API call records.

- Contribute to infrastructure-as-code workflows for detection deployment (e.g., Terraform, GitOps pipelines).

- Collaborate with Threat Intelligence and IR teams to translate threat actor TTPs — including those targeting AI systems — into actionable detections.

- Participate in detection tuning, red/blue team exercises, and post-incident reviews, including adversarial testing of AI-assisted detection logic.

- Maintain availability for 24x7 on-call rotation and ensure timely response to security incidents during standard EST business hours.

Required Qualifications

- 2-4 years in a security engineering or other relevant security operations role.

- Proficiency with Splunk, Elastic Stack, Google SecOps (Chronicle), and/or Logstash.

- Strong programming or scripting experience in Python and SQL.

- Working experience authoring detection logic using YARA-L, Sigma, or equivalent formats.

- Demonstrated AI literacy: hands-on experience using LLM APIs (e.g., OpenAI, Anthropic, Google Gemini) or AI/ML frameworks for security use cases, including prompt engineering, retrieval-augmented generation (RAG), or agentic workflows.

- Understanding of AI/ML concepts relevant to detection: anomaly detection, clustering, embedding models, LLM-based enrichment, and the limitations and failure modes of these approaches.

- Ability to assess and detect AI-specific threats: prompt injection, model inversion, training data poisoning, and LLM-facilitated social engineering.

- Experience working with cloud-scale security data and log management tools.

- Familiarity with MITRE ATT&CK, threat modeling, and behavioral-based detections.

- Knowledge of Infrastructure-as-Code (IaC) and version control systems (e.g., GitHub, Terraform, GitLab CI/CD).

Preferred Qualifications

- Industry security certifications such as GCIA, GCIH, GCFA, Security+, or AI/ML security credentials.

- Experience with Google Cloud Platform (GCP) and Google Kubernetes Engine (GKE), including GKE security posture management, audit logging, and cloud-native workload monitoring.

- Experience building or operating SOAR integrations with LLM-assisted triage or response recommendations.

- Hands-on experience with agentic AI frameworks (e.g., LangChain, LlamaIndex, or custom tool-use pipelines) applied to security automation.

- Familiarity with Snowflake's Security Data Lake or cloud-native log pipelines, including telemetry from AI platforms (e.g., OpenAI API logs, Azure AI services).

- Exposure to red team/blue team collaboration, threat hunting, or adversary emulation frameworks, with emphasis on AI-enabled attack scenarios.

- Experience red-teaming or evaluating LLM-based systems for security weaknesses.

- Contributions to open-source detection or AI security tooling projects.

Ideal Candidate Will Thrive In Our Culture:

- Demonstrates a strong passion for security and a commitment to protecting digital identities.

- Keeps pace with the rapidly evolving AI threat landscape and proactively translates emerging research into detection coverage.

- Adapts well to changing priorities and can shift gears quickly in a fast-paced environment.

- Exhibits excellent oral and written communication skills, including the ability to explain AI-driven detection decisions to non-technical stakeholders.

- Works well within a team, but is also self-driven and capable of managing tasks independently.

- Shows a continuous desire for learning and professional development, staying current with advances in both cybersecurity and applied AI.

Location:

Candidates must be located in the continental U.S. and able to work on-site in Mountain View, CA.
