Security Engineer, Application Security

Ridgeline is on the hunt for an experienced Application Security Engineer to join our growing Security Engineering team and help us scale secure development practices across the company. As a Staff Security Engineer at Ridgeline, you will play a key role in identifying and solving complex application security problems through development-heavy solutions that enhance the security of our software platform.

This is a builder’s role — perfect for someone who can write production-quality code, solve security problems with software, and influence others through hands-on technical leadership. You’ll work closely with engineers to embed security into our development lifecycle and help drive adoption of secure-by-default approaches within key product areas.

Ridgeline places a strategic emphasis on the responsible and innovative use of AI, integrating it deeply into our platform, internal tools, and engineering processes. We are especially excited to work with candidates who are curious and motivated to explore how AI can be thoughtfully applied to solve application security problems — whether that’s through LLM-assisted analysis, anomaly detection, or next-gen automation. Prior experience is great, but passion and creativity in this space matter even more.

What will you do?

• Drive security improvements by developing and deploying security controls into CI/CD pipelines and secure development workflows within Ridgeline’s products.
• Partner with product and platform engineers to improve the security posture of applications through secure design guidance, threat modeling, and code-level improvements.
• Design, develop, and maintain automation and tooling for application security (e.g., static analysis pipelines, dependency scanners, or custom security linters).
• Perform security reviews of architecture, design, and code to identify and fix vulnerabilities early in the development lifecycle.
• Research new and emerging threats and translate those into actionable security improvements.
• Collaborate across teams to improve adoption of security tools and practices, ensuring they integrate seamlessly into developer workflows.
• Advocate for and contribute to secure coding education across engineering teams.
• Demonstrate ownership of application security projects, delivering solutions from planning through rollout and maintenance.
• Foster a collaborative environment rooted in learning, teaching, and trust.

Desired Skills and Experience:

• 4+ years of experience in software development or application security roles.
• Bachelor’s degree in Computer Science or a related discipline, or equivalent practical experience.
• Strong proficiency in one or more modern programming languages (e.g., Python, Java/Kotlin, JavaScript/TypeScript, Go). Python experience is a plus.
• Hands-on experience implementing and operating security controls within CI/CD pipelines (e.g., GitHub Actions, container image build tools, or similar).
• Demonstrated success building custom security tooling or integrating open-source tools for static/dynamic/code analysis at scale.
• In-depth understanding of common application vulnerabilities (OWASP Top 10, CWE) and practical mitigation strategies.
• Ability to read and understand modern application architectures and assess them from a security perspective.
• Clear, thoughtful communicator who can explain technical security concepts to a broad audience.
• Strong sense of ownership, and a passion for continuously improving systems and processes.
• Practical development experience — e.g., you’ve built internal tools, production services, or contributed meaningful features to software systems.
• Security Architect with AI Fluency: Can evaluate risks tied to LLMs, embeddings, APIs, and fine-tuned models; balances security and usability tradeoffs.

Nice to haves:

• Strong interest or experience in applying AI to application security problems — including but not limited to LLM-powered static analysis, code classification, threat modeling assistance, or anomaly detection.
• Familiarity with AWS, particularly around IAM, container services, Lambda, and related infrastructure.
• Experience with secure design or threat modeling at the application or system level.
• Participation in bug bounty programs, security research, open-source contributions, or other forms of community engagement.
• Experience mentoring engineers or helping teams adopt secure development practices at scale.
