Looking for Senior Application Security Engineer II jobs? This critical cybersecurity role sits at the intersection of software development and security, acting as a force multiplier to build security directly into the fabric of an organization's products. Unlike traditional security roles focused on perimeter defense, a Senior Application Security Engineer II is an embedded partner and enabler for development teams. Their core mission is to shift security left, integrating it seamlessly into the Software Development Lifecycle (SDLC) to empower engineers to build secure software by design, without sacrificing innovation or velocity. Professionals in these jobs typically shoulder a blend of strategic and hands-on technical responsibilities. A primary duty is architecting and implementing security automation within CI/CD pipelines. This involves building, maintaining, and optimizing tools for Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA). They don't just run scans; they interpret results, prioritize findings, and work collaboratively with developers to provide actionable remediation guidance. Acting as a trusted advisor, they conduct secure code reviews, design secure-by-default architectures, and deliver training on secure coding practices to uplift the entire engineering organization's security knowledge. The skill set for Senior Application Security Engineer II jobs is uniquely hybrid. A strong software engineering background is non-negotiable, with proficiency in languages like Python, Java, Go, or C#. This enables them to speak the developers' language and create effective security tooling. They possess deep, practical knowledge of application security vulnerabilities (OWASP Top 10), mitigation techniques, and modern development practices, including Git and cloud platforms like AWS, Azure, or GCP. Beyond technical prowess, exceptional communication and collaboration skills are vital. They must translate complex security risks into business context for leadership and into practical, non-disruptive steps for engineering teams. Successful candidates demonstrate a proven ability to partner with developers, champion a culture of security ownership, and automate repetitive tasks to scale security efforts effectively. If you are passionate about solving complex security challenges through automation, enablement, and deep technical collaboration, exploring Senior Application Security Engineer II jobs could be your next career step.
