IT Systems Engineer

Obsidian Security is a global leader in cyber security protecting the SaaS and non-human identity layer modern enterprises run on — from Salesforce and Snowflake to the AI agents now deployed inside them. 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.

In 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.

With 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.

We're hiring an experienced Lead IT Systems Engineer to be the senior technical owner of Obsidian's identity, endpoint, and IT platform foundation, and to help us operate that foundation as code. You will own how identity flows from our HR system into Okta and out to every application, how our device fleet is managed and hardened, and how the configuration behind all of it lives as version-controlled, AI- and human-authored code. You will set the bar for how a modern, security-first IT organization runs in an AI-forward company.

This is a high-leverage seat at a pivotal moment. Our identity platform is being stood up with a lifecycle orchestration layer in front of it, and we are moving the whole stack onto an infrastructure-as-code operating model. We are looking for a senior technical owner to set the bar for identity architecture, configuration-as-code, AI-augmented operations, and how a lean IT function leverages AI and automation to grow the function. 

You will report directly to the VP of Business Systems, Data & IT. You will partner closely with Security, DevOps, HR, Finance, and the go-to-market teams, and you will have an opportunity to lead a lean team across the Business Systems, Data & IT function.
