About BlueConic: We are building products with AI at the core, and we build our products using AI. Agents and skills write a share of our code, run parts of our SDLC, and operate alongside our engineers every day. We need a Staff Security Engineer who can secure that reality, not the SDLC of five years ago. In conjunction with the CISO you represent security across the product development lifecycle, lead threat modeling and vulnerability management, and drive secure coding practices in an environment where code review means reviewing agent output as often as human output. You will use AI agents and skills as core tools of your own job: building automation, running threat models, triaging vulnerabilities, and scaling your impact across teams. Lead Security Engineer What you'll do Drive adoption of secure coding practices, including practices specific to AI-generated and AI-assisted code. Conduct security assessments, threat modeling, and risk analysis so threats are understood, documented, and mitigated. Automate security processes wherever it creates leverage, using scripts, AI agents, and AI skills as your default tools. Identify emerging classes of vulnerabilities and build solutions before they become incidents. Build and maintain security tooling, automation, and monitoring capabilities, including custom agents and skills for security workflows Threat model agentic systems: prompt injection, tool misuse, unauthorized agent privilege escalation, and data exfiltration through agent actions. Define guardrails and human-in-the-loop checkpoints for agent-driven changes to code and infrastructure. Set and enforce review standards for code produced by AI coding agents, including required checks before agent-authored changes reach production. Break large, cross-team security projects into individual tasks. Manage scope across teams and drive projects to closure. Monitor, investigate, and respond to security incidents, coordinating remediation across teams. S

Role Overview As a Staff Security Engineer, you'll get involved early with Product and Software Engineering teams to embed security into our architecture and processes as they design, build, and ship. You'll also be someone the Security team can pull into any project, at any phase and regardless of domain, to make sure it lands on the right security outcome. This is a hands-on role, and you don't need to be an expert in all three areas: application security, cloud security, and security automation and tooling. You should have strong, demonstrated depth in one of the three, along with enough working knowledge of the other two to contribute without hand-holding and to be a trusted voice on technical decisions outside the systems you personally own. What You'll Do Partner with Engineering, DevOps, and Product across projects, providing security input at any phase of design or build, regardless of domain. Guide secure design and code review for web and mobile applications, and help manage core AppSec tooling (SAST, SCA, secret scanning, DAST, ASM, and mobile security tooling).
