Senior Software Engineer - Data Pipelines

Obsidian Security is the leading SaaS security platform, trusted by global enterprises like Snowflake, T‑Mobile, and Algolia. We protect 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.

Founded in 2017 and backed by top investors like Greylock, Obsidian was built to close a critical gap: securing SaaS apps where business happens—Microsoft 365, Salesforce, and hundreds more. The company offers a complete SaaS security platform to reduce risk, detect and respond to threats, and prevent breaches at the source.

With AI driving rapid SaaS growth and complexity, agentic AI tools gain privileged access to sensitive data through integrations, creating new risks most security tools miss. Obsidian uniquely detects anomalous OAuth token activity and manages integration risks. Recognizing that SaaS security needs to evolve, Obsidian enables growing organizations to start with a lightweight, prevention‑focused browser extension and expand coverage over time.

With global momentum, a growing partner ecosystem and a major fundraise ahead, Obsidian is scaling rapidly toward long‑term growth and IPO readiness.
