About the role As a Staff Security Engineer, you will play a key technical role in improving the security of RTB House systems, infrastructure, and software development practices. You will work across engineering teams, including Software Engineering, Platform, Infrastructure, DevOps, Cloud, and our Security Operations Center.

Your goal will be to identify systemic security risks, design practical solutions, and help engineering teams build secure systems by default. This is a senior individual contributor role with broad technical influence, reporting directly to the VP of Engineering. You will not be limited to operating security tools or responding to individual vulnerabilities. You will look at security across the organization, identify areas where we can improve, define technical security standards and architecture, and work directly with engineering teams to implement them.

You will also act as a bridge between Security Operations and Engineering. Insights from incidents, vulnerabilities, threat intelligence, and security assessments should result in concrete improvements to architecture, tooling, development practices, and technical controls. We are looking for someone who is comfortable going deep technically while also being able to influence engineering decisions across multiple teams.

You Will: Identify systemic security risks across applications, on-prem infrastructure, cloud environments, internal platforms, and software development processes. Perform security architecture reviews for existing and new systems. Work directly with engineering teams to identify security weaknesses early in the software development lifecycle and design practical ways to address them. Partner with our SOC to improve detection capabilities, analyze attack patterns and incidents, and translate findings into better detection rules, security controls, and long term architectural improvements.
