Senior Security Data Engineer

We're hiring Security Data Engineers to join our Manchester team and work at the heart of our SaaS and AI security platform. This is a data engineering role first — you'll spend most of your time building and maintaining the data pipelines that power Obsidian's detection and analytics capabilities.

The role sits at an interesting intersection: the work is technically demanding data engineering, but the context is security. You don't need a security CV — you need to be a strong data engineer who is curious about how modern SaaS and AI platforms work, and what makes them risky.

• →Build and maintain data retrieval integrations across major SaaS and AI platforms — connecting to APIs, handling auth flows, and ensuring reliable telemetry ingestion.
• →Design and develop dbt models in SQL on Clickhouse and Databricks, transforming raw platform data into clean, structured datasets ready for analysis.
• →Build rule-based checks to identify risky configurations and unusual activity patterns across SaaS and AI platforms — translating security insight into logic.
• →Develop a working understanding of how SaaS and AI platforms are structured and where security risks emerge, to inform what data we collect and what we look for.
• →Debug data quality and detection issues in customer environments, working closely with the wider engineering and customer success teams.=

• 4+ years of hands-on data engineering experience, including dbt and SQL.
• Strong SQL — you're comfortable writing complex data models and transformations from scratch.
• Experience building or maintaining data pipelines that process high-volume event or log data.
• Comfortable working with REST APIs and integrating data from third-party platforms.
• Python proficiency for scripting, data manipulation, and pipeline logic.
• Some exposure to security concepts — enough to understand what 'risky' looks like in a SaaS or cloud context. 
• This can come from working in a security company, cloud engineering, compliance, or your own interest.

• Hands-on experience with Clickhouse or Databricks.
• Familiarity with SaaS platforms such as Google Workspace, Microsoft 365, Salesforce, or Okta — from any angle (admin, engineering, or security).
• Understanding of identity and authentication concepts: OAuth, SAML, SSO, and directory services.
• Experience working with security telemetry — audit logs, API event streams, or similar.
• Interest in AI/LLM platforms and how they introduce new security considerations.
