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. AppSec and DevSecOps experience is strongly preferred; SAST/DAST/SCA and Java expertise are a plus.
What you will do
- Engineer and deploy AI-enabled secure code scanning capabilities and “Golden Images” to drive secure-from-the-start adoption.
- Automate the development of secure coding patterns and integrate them with traditional and Agentic SDLC workflows.
- Architect the integration of continuous security scanning tools (SAST, DAST, SCA) into enterprise CI/CD pipelines, tuning them to eliminate noise.
- 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.
