AI-first Application Security Engineer

Job Description

We are looking for an Application Security Engineer who uses AI-assisted tooling to build security into the software development lifecycle (SDLC) and reduce the number of vulnerabilities deployed to production. You will use AI to speed up security analysis, automate feedback loops, and scale secure engineering practices across teams, while applying human judgment to validate findings, make risk decisions, and guide engineers.

_This position offers hybrid setup with the flexibility to work from any location in Lithuania, whether it's your home or our dynamic offices in Vilnius and Kaunas._

• Secure all steps of the software development lifecycle holistically, using AI-assisted analysis to identify risks early

• Professionally secure the software delivery process, from build to deployment
• Conduct secure coding awareness training and share best practices, including how to use AI coding assistants safely and securely
• Maintain a strong understanding of programming languages (Java, Swift) to review code and provide actionable guidance
• Communicate effectively with engineers to promote "security by design"
• Align with engineering leadership to prioritize and streamline security fixes, making remediation a positive experience for software engineers
• Monitor and report potential vulnerabilities, using AI to deduplicate and enrich findings and automatically create tickets
• Drive remediation within engineering teams and track progress to closure
• Develop threat models and attack trees for in-scope applications, using AI to accelerate drafting while validating outputs with domain expertise
• Set up and coordinate penetration tests across web and mobile (Android/iOS) applications, and track findings for remediation
• Support attack modeling and red teaming exercises
