Founded in 2017, Obsidian Security was created to close a critical gap: securing the SaaS applications where modern business happens—platforms like Microsoft 365, Salesforce, and hundreds more. Backed by top investors including Greylock, Norwest Venture Partners, and IVP, we’ve built a complete SaaS security platform to reduce risk, detect and respond to threats, and prevent breaches at the source. Our team includes leaders who helped define the categories of endpoint and identity security at CrowdStrike, Okta, Cylance, and Carbon Black. Now, we’re transforming how SaaS is secured—in the era of agentic AI. Today, Obsidian is trusted by global enterprises like Snowflake, T-Mobile, and Pure Storage. We protect more than 200 organizations across North America, Europe, the Middle East, Southeast Asia, Australia, and New Zealand—including many of the world’s largest Fortune 1000 and Global 2000 companies. With strong global momentum, a growing partner ecosystem including SentinelOne, Databricks, and Google Cloud, and a major fundraise on the horizon, we’re scaling quickly toward long‑term growth and IPO readiness. Join us as we define the future of SaaS security!
As a Staff SRE at Obsidian, you will define and drive the company‑wide reliability vision for a complex, multi‑tenant SaaS platform serving enterprise and financial customers.

- Detection & Observability - Build intelligent detection systems (anomaly detection, connector health models) and enable self‑service observability.
- Incident Management - Define and evolve a tiered incident communication strategy, improve response practices, and lead postmortems to strengthen reliability and customer trust.
- Execution - Contribute hands‑on to system design, monitoring, and debugging across distributed systems and data pipelines.

- CI/CD systems (GitLab CI/CD, ArgoCD, etc.)
- Proven experience designing and scaling reliability systems for multi‑tenant SaaS platforms
- Strong debugging and systems thinking across distributed microservices and legacy systems
- Demonstrated ability to lead initiatives that improve incident detection, response, and system resilience
- Hands‑on engineering approach with a track record of building—not just configuring—reliability systems
Preferred Qualifications
- Experience in B2B SaaS serving enterprise or financial customers
- Familiarity with third‑party SaaS connector architectures and ingestion patterns
