Nice to have * 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. ## Description 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. What you'll do * 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.= ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [You can’t hack what you can’t see](https://www.wearedevelopers.com/videos/41-you-can-t-hack-what-you-can-t-see) - [Advanced Cypress: custom assertions and tasks](https://www.wearedevelopers.com/videos/790-advanced-cypress-custom-assertions-and-tasks) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Data Analyst Salary in the UK](https://www.wearedevelopers.com/magazine/278-data-analyst-salary-in-the-uk) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Dev Digest 138 - Are you secure about this?](https://www.wearedevelopers.com/magazine/486-dev-digest-138-are-you-secure-about-this) - [Events like RSAC Get You CISOs.
