Top Tech Jobs & Startup Jobs in San Francisco Bay Area, CA

Design and train LLMs and agentic systems for cybersecurity using RLHF/RLAIF and supervised fine-tuning. Build agent architectures, tooling, retrieval/memory, and evaluation pipelines with rigorous statistical benchmarking. Optimize prompts and inference, collaborate with engineers to productionize prototypes, and drive research on agent planning, safety, and reliability.

As a Principal Data Engineer, you will design and implement LLM, AI-powered security data platforms, mentor engineers, and drive the adoption of data solutions across teams.

Conduct cloud-focused Red Team/Blue Team (CRTBT) engagements, emulating adversary TTPs against customer cloud environments, collaborate with client SOC/IR teams, manage engagements end-to-end, develop automation and tooling for adversary emulation, and recommend long-term enhancements to improve cloud detection and response.

Lead planning, deployment, and operational support for CrowdStrike Falcon cloud security modules (CWP, CSPM, ASPM, SSPM). Perform implementations, scripting, IaC, container and CI/CD integrations, troubleshooting, customer training, mentorship, cross-team coordination, and support incident response and compromise assessments.

Perform proactive and active threat hunting across government cloud environments, analyze adversary activity, develop and implement detections, conduct intrusion and forensic analysis, contribute to threat intelligence and detection engineering, and communicate findings to technical and executive stakeholders while enhancing Falcon platform capabilities.

Lead research and engineering of production-grade LLM/GenAI systems for cybersecurity: design models and architectures, drive data labeling and evaluation, collaborate with product and engineering to deploy scalable solutions, mentor data scientists, set technical strategy, and advance AI safety, red-teaming, and applied ML innovations for detection and operational use.

Lead applied research on agentic AI for cybersecurity: develop efficient post-trained models, agent designs, and rigorous evaluation/verification. Partner with security teams to translate research into products, run experiments, and publish novel techniques.

Lead development and deployment of large-scale LLM and GenAI solutions for cybersecurity. Drive research strategy, model training, evaluation, safety/red-teaming, and cross-functional productization. Mentor data scientists, set technical standards, and represent the team through publications and thought leadership.

Senior SRE owning availability, automation, and observability for CI/CD platform services. Build and operate infrastructure, run on-call, lead incident response, mentor engineers, drive design/capacity planning, integrate AI-assisted workflows, and improve cross-team reliability.

Conduct cloud-focused Red Team/Blue Team engagements as the Blue Teamer: support SOC/IR in real-time threat hunting, detection engineering, and incident response during adversary emulation. Manage engagements end-to-end, deliver reports, and recommend long-term enhancements to improve detection, response, and recovery. Provide client-facing consulting, project management, and relationship-building with technical and executive stakeholders.
