We're looking for a Principal Security Engineer to join Pipedrive as a technical builder responsible for engineering the security architecture of our SaaS platform, corporate operations and the tools and methods the security team will use. This position is a high-level engineering role focused on building the systems that automate security at scale and simultaneously address the threats to them. The role will also be an active partner across the business acting in an advisory role to both technical and business partners to ensure their vision and objectives can be safely met.

Your new adventure:

• Security Engineering & Agentic Automation

Engineer and architect scalable security solutions for cloud-native environments to protect customer data, applications, and networks. Develop autonomous security agents and workflows using LLMs and agentic frameworks to automate complex tasks such as event monitoring and triage, threat modeling, vulnerability discovery and remediation. Design and build automated identity and access management (IAM), data encryption, and threat detection capabilities that function without manual intervention.

AI Security Architecture & Integrity

• Create technical baselines and security controls for AI-driven products, ensuring data model integrity and the security of training pipelines.
• Build defenses against emerging AI-specific threats, such as prompt injection, model inversion, and data leakage, within both customer-facing and internal AI initiatives.
• Conduct deep-dive technical reviews of AI architectures to ensure security is embedded into the foundation of every new model and automation project.

Technical Leadership & Collaboration

• Lead the response effort during active security incidents and provide expert analysis when called upon for internal investigations.
• Participate in an off‑hours on‑call rotation with a 30‑minute response SLA, serving as the primary security SME for high‑severity alerts, driving swift containment and mitigation, and leading incident orchestration across engineering teams and internal stakeholders when critical security events arise.
• Partner with Engineering and SRE teams to engineer security directly into our Platform, CI/CD pipelines and Infrastructure‑as‑Code (IaC).
• Provide technical mentorship to security and engineering teams, fostering a culture where security is viewed as an engineering challenge to be solved with code.
• Ensure that all engineered solutions align with the broader enterprise security strategy.
