What the job involves
- Glean is looking for an experienced Application Security Engineer with a primary focus on ensuring that our entire technology stack is free of software vulnerabilities (CVEs)
- This role is responsible for securing our base OS images, ensuring all open-source software (OSS) dependencies are scanned and patched, and integrating cutting-edge security tools into our CI/CD pipeline
- The ideal candidate will drive the adoption of solutions like Google’s Assured Open Source Software (OSS) and explore alternative approaches to enhance software security
- This role will lead the vulnerability management charter at Glean, identifying, evaluating, and implementing new security technologies and processes to proactively protect our infrastructure
- Own and lead the vulnerability management lifecycle, ensuring our entire tech stack is free from known CVEs
- Implement and manage secure base OS images, ensuring all underlying systems remain hardened against security threats
- Continuously scan, monitor, and patch OSS dependencies to mitigate supply chain risks and enforce best practices for dependency management
- Research and evaluate trusted open-source security solutions like Google’s Assured Open Source Software and recommend their adoption where applicable
- Work closely with engineering teams to integrate state-of-the-art SAST, DAST, and dependency scanning tools into the CI/CD pipeline to detect and remediate vulnerabilities early
- Define and maintain best practices for secure coding to ensure all code developed by Glean engineers is free from vulnerabilities
- Develop automated security validation tests to enforce vulnerability-free deployments across the stack
- Lead the adoption and, if necessary, develop custom security solutions to manage and mitigate security risks at scale
- Provide security guidance, training, and mentorship to engineering teams to foster a security-first culture at Glean
Our take
Glean is an intuitive digital assistant which allows employees to search across all their apps and find the information and tools that they need more quickly.
With so many SaaS apps being used by modern day companies, overwhelm and inefficiency inevitably enter the equation. Glean’s search engine is proving popular for how it unifies and centralizes all these distributed tools and data.
It’s been quite a start to life at Glean, having emerged from stealth in 2021, it received a $1B valuation in early 2022, thus achieving unicorn status. Since then, the company has gone on to raise substantial funding and bring its valuation up to $7.2B in 2025. With this impressive growth, its secured some big name customers like Grammarly, databricks, and Rubrik.
That Glean was co-founded by a quartet with senior experience at Google, Microsoft, Uber, and Facebook stands the company in good stead. However, it’s the fact that its search engine is solving a new, but very real problem in the workplace that’s seen its popularity surge so quickly, which it’s likely to continue to do in the future. And its adaptability to include new AI capabilities to its platform, such as generative AI, has Glean well set to see further growth.
