Senior Security Engineer, DFIR

At ClickUp, we're building the future of work: the first truly converged AI workspace unifying tasks, docs, chat, calendar, and enterprise search, all supercharged by context-driven AI. We are an AI-native company. Every team member is expected to leverage AI daily, and we evaluate AI fluency as part of our hiring process. Join us and help redefine what's possible. 🚀

Security at ClickUp is engineering-focused. We partner with teams across the company to protect our platform, our internal systems and our customers through secure design, defensive controls, detection and response. We build tooling and automation, including AI-powered workflows, to turn what we learn into lasting improvements.

Application Security at ClickUp investigates threats, platform abuse and security incidents affecting our product and internal systems. We turn investigation findings into response tooling, automation and stronger product defenses, partnering with engineering and product teams to prevent repeat issues. This is an engineering-first team that uses AI tools and agentic workflows to improve how we investigate and respond.

You will support this mission by thinking like a developer, breaking down a problem that we face, testing a method to approach it with automation, and implementing solutions that yield compounding value. Your skills to uncover threat indicators will be the foundation of this work.

• Multiple years of experience in technology or software development, including building and maintaining tooling or automation that solves operational problems.

• Practical experience using AI-assisted development or agentic workflows for engineering or security work, with an ability to validate their output and recognize when human review is needed.

• Experience investigating security threats or platform abuse: analyzing logs and other evidence, identifying threat indicators, and explaining findings and impact.

• Ability to translate a security finding into a practical software design change, response improvement or automated control.

• Experience working with cloud or SaaS systems, including using their application, identity or audit data to investigate suspicious activity.

• Clear written communication: findings and recommendations that another team can act on, supported by evidence.

• Ability to build relationships and mentor others on technical topics, including security.

• Experience using AI agents in a SOC or other incident response workflows.

• Understanding of agent security risks, including the confused deputy problem and the lethal trifecta.

• You can facilitate a conversation rather than dictate it.

• 3+ years of software development experience and 1+ year of security-specific experience.

• Experience with security tools such as SAST, DAST, RASP, dependency checkers and SIEM.

• 1 year of AWS experience, including IAM and least-privilege architectures.

Cloud and SaaS environments, software development and security automation, AI-assisted and agentic workflows, and security investigation tooling.
