The Obsidian Security platform gives unified visibility into every human and machine identity, app, and integration across their SaaS estate, detects identity-based and supply chain attacks in real time, and enforces least-privilege access before it's exploited. Trusted by major Fortune 500 companies T-Mobile, Workday, Snowflake, and S&P Global, Obsidian ranked No. 95 on the 2025 Deloitte Technology Fast 500™, growing nearly 1000% from 2021-2024 - helping CISOs turn an unmonitored attack surface into one they can govern with confidence. Obsidian has also been recognized by Forbes as America's Best Startup Employers in 2026.\nIn August 2026, Obsidian raised $85 million in Series D financing led by Crescent Cove Advisors, with participation from existing investors including Greylock Partners, Menlo Ventures, Norwest Venture Partners, IVP, Wing Ventures, and GV - pushing Obsidian's valuation to $1.1 billion, crossing into unicorn status. Obsidian is using the funding to deepen its R&D in agentic AI security and extend its platform as the standard for governing what AI agents can access and do inside third-party applications.\nWith global momentum, a growing partner ecosystem including SentinelOne, Databricks, and Google Cloud, and fresh capital from its Series D behind it, Obsidian is scaling rapidly toward long-term growth and IPO readiness.\nAbout the Role\nAI is becoming the fastest-moving attack surface in the enterprise. Copilot, ChatGPT Enterprise, Gemini, Claude, and a growing wave of agentic tools are being connected to corporate SaaS applications faster than many security teams can evaluate them. These systems introduce broad OAuth scopes, opaque data flows, sensitive data exposure, and non-human identities that can act on behalf of employees.\nObsidian Security sits directly in the path of this shift.\nAs an AI Security Engineer in Taiwan, you will help define how Obsidian discovers, understands, and mitigates risks across AI and agentic platforms. You will research emerging threats, develop security and data models, and build highly available products that protect enterprise customers.\nThis is a hands-on role at the intersection of security research, data engineering, and product development. You will work directly with security telemetry and production systems because, in this rapidly evolving space, security judgment, data analysis, and engineering execution are inseparable.\nYou will collaborate closely with Security Research, Detection Engineering, Product Management, Data Platform, and Site Reliability Engineering teams across Taiwan, the US, the UK, and Australia.\nWhat You’ll Do\nDevelop deep expertise in how enterprise AI platforms-including ChatGPT Enterprise, Microsoft Copilot, Gemini, Claude, Glean, and agentic frameworks-authenticate, access data, request permissions, and interact with corporate SaaS applications.\nResearch emerging AI security threats, including prompt injection, tool and agent misuse, RAG poisoning, insecure plugins, excessive agency, data leakage, over-permissioned integrations, and compromised non-human identities.\nDevelop threat models for AI applications, agents, models, integrations, identities, permissions, tools, and data flows.\nDesign data models that represent AI assets, identities, access relationships, permissions, activities, risks, and attack paths.\nPrototype and deliver production-grade AI security products and capabilities.\nBuild backend services and APIs for AI asset discovery, security analysis, risk assessment, detection, investigation, and remediation.\nBuild scalable pipelines that ingest, normalize, enrich, correlate, and analyze high-volume security telemetry.\nWrite queries and analysis logic that transform raw activity and configuration data into actionable security findings.\nDevelop detection rules and behavioral models for suspicious AI and agentic activity.\nEvaluate APIs, audit logs, authentication mechanisms, OAuth permissions, and security controls provided by AI platforms.\nWork with Product Management and customers to understand emerging use cases and turn ambiguous security problems into practical product capabilities.\nPartner with Detection Engineering and Security Research to validate threat hypotheses and improve detection coverage.\nCollaborate with platform and SRE teams to ensure services are secure, observable, highly available, and operationally efficient.\nImprove engineering productivity, pipeline performance, development velocity, and cloud cost efficiency.\nContribute to technical designs, code reviews, testing strategies, operational readiness, and engineering standards.\nShare research and technical knowledge with engineering teams and help shape Obsidian’s long-term AI security strategy.\nWhat We’re Looking For\nStrong software engineering experience building production-quality backend services, cloud-native applications, data platforms, or security products.\nHands-on programming experience in one or more languages such as Python, Go, Java, Kotlin, or a comparable backend language.\nExperience designing and building scalable APIs, distributed systems, or data-processing pipelines.\nStrong data analysis skills and the ability to investigate complex behavior using SQL or other query languages.\nFamiliarity with cloud infrastructure, SaaS platforms, identity systems, authentication, authorization, and OAuth.\nUnderstanding of security fundamentals, including identities, permissions, access controls, vulnerabilities, attack techniques, and risk assessment.\nAbility to translate ambiguous security risks into clear threat models, data requirements, and production capabilities.\nStrong engineering judgment across scalability, reliability, security, performance, maintainability, and cost.\nCuriosity and a willingness to rapidly learn unfamiliar AI platforms, APIs, security models, and attack techniques.\nAbility to work independently while collaborating effectively with security researchers, product managers, and engineers.\nStrong written and verbal communication skills in English.\nNice to Have\nExperience building cybersecurity, identity security, SaaS security, threat detection, SIEM, EDR, XDR, or security analytics products.\nExperience researching or developing protections for AI applications, large language models, copilots, or autonomous agents.\nFamiliarity with AI security risks such as prompt injection, RAG poisoning, insecure tool use, model abuse, excessive agency, and sensitive-data disclosure.\nExperience with LLM application frameworks, agent protocols, tool integrations, vector databases, or retrieval-augmented generation systems.\nExperience working with SaaS audit logs, identity telemetry, OAuth grants, application configurations, or security events.\nExperience developing detection rules, behavioral analytics, risk models, or attack-path analysis.\nExperience with large-scale streaming or batch-processing technologies.\nExperience using machine learning or generative AI to analyze security data or automate investigations.\nContributions to security research, open-source projects, technical publications, or responsible vulnerability disclosures.\nExperience collaborating with globally distributed engineering teams.\nMandarin proficiency.\nWhat Success Looks Like\nObsidian gains deep, actionable visibility into enterprise AI applications, agents, integrations, identities, permissions, and activities.\nEmerging AI threats are translated quickly into scalable product capabilities and effective detections.\nCustomers receive accurate, explainable, and actionable findings about their AI security risks.\nAI security services and data pipelines operate reliably at enterprise scale while maintaining strong cost efficiency.\nResearch, product, detection, and engineering teams work through a clear and repeatable process for developing AI security capabilities.\nYou help establish Obsidian as a technical leader in securing enterprise AI and agentic systems.\nEmployee Benefits:\nOur competitive benefits packages are designed to support our employees' well-being, both at work and
