About the role
We are looking for a Senior Application Security Engineer to architect and build automated security layers within the SDLC, engineering AI-enabled secure code scanning, hardened baseline automation, and CI/CD security tooling integration within a large-scale financial services program. You will work primarily in Python to build automated security runbooks, deploy and tune scanning tools, and provide code-level remediation guidance to development teams - operating with full autonomy and no daily supervision.

Act as a senior technical SME, reading and reviewing complex application code (Java/Python) to provide software engineers with highly specific, code-level remediation guidance.
Must haves
5+ years of software engineering experience, ideally with a focus on Application Security and DevSecOps;
Strong coding and architectural proficiency in Python for security automation and scripting;
Fully autonomous execution capability, requiring no daily supervision to map out and build automated security runbooks;
Upper-intermediate English level.
Nice to haves
Deep, hands-on expertise deploying and tuning modern application security testing tools, including SAST, DAST, and SCA, and integrating them into complex CI/CD orchestration ecosystems;
Experience integrating LLMs, AI agents, or automated coding assistants to streamline vulnerability triaging or secure code generation;
Advanced application threat modeling experience;
Ability to confidently read, review, and secure enterprise source Java code.
