About The Position

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.

Requirements

Must be authorized to work for ANY employer in the US (e.g., Green card holders, TN visa holders, GC EAD, H4 EAD, U4U with EAD), as we are unable to sponsor or take over employment visa sponsorship at this time
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.

Responsibilities

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.
