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

Own end-to-end quality for new features across the operator portal, backend platform, and endpoint agent. Translate requirements into runnable acceptance coverage, build and maintain parallel browser test frameworks, validate APIs and contracts, and integrate suites into CI release gates. Curate automated and AI-generated scenarios, assess test risk, report coverage and failures, and close quality gaps. The role also drives adoption of shared tooling and may involve containerized environments, cloud platforms, virtualization, performance testing, and security product testing.

Designs and ships macOS endpoint detection and response agents, including privileged daemons, system extensions, telemetry instrumentation, event correlation, prevention logic, and tamper protection. The role requires optimizing high-volume sensor performance, building automated and VM-based tests, resolving customer escalations, and partnering with security research, AI, platform, and product teams. It also involves code review, mentoring, release-quality ownership, and on-call support.

Build and optimize production systems for heterogeneous machine learning models, including small models, medium models, and LLMs. Develop distributed systems for large-scale data processing, model training and validation, experimentation, deployment, and CI/CD. Ensure system robustness, scalability, and long-term maintainability while supporting data management and evolving model-development workflows.

Build Ent’s forward-deployed engineering function by leading cybersecurity product deployments for strategic customers. Configure and validate endpoint security, insider risk, DLP, EDR, security awareness, and AI security modules; translate customer workflows into scalable deployment patterns; create playbooks, documentation, training, and metrics; provide product feedback; and collaborate with security research teams to improve detection and prevention capabilities.

Build and own a cross-platform endpoint security agent, including collection, policy evaluation, enforcement, transport, installers, updates, offline behavior, diagnostics, and performance controls. Develop secure, reliable software for Windows, macOS, or Linux; maintain testing and CI infrastructure; integrate with backend services and browser extensions; handle escalations; and participate in code and design reviews plus on-call support.

Build Ent’s endpoint data-protection layer for classifying sensitive data, tracing provenance, and enforcing egress policies across devices, applications, networks, removable media, browsers, and AI tools. Develop cross-platform interception and content inspection capabilities, integrate on-device language models, optimize performance, produce forensic evidence, investigate compatibility issues, and improve detection precision for enterprise customers.

Build and maintain Linux endpoint detection and response sensors using kernel and user-mode components, eBPF, LSM, and audit subsystems. Develop high-fidelity detection and prevention, anti-tamper protections, telemetry, performance optimizations, and automated testing. Investigate severe customer escalations involving crashes, hangs, regressions, and missed detections. Collaborate across security research, AI, platform, and product teams while mentoring engineers and supporting release quality and on-call responsibilities.
