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 combining software engineering experience, security implementation and/or architecture experience.
- 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 (SAST, DAST, 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.

PERKS AND BENEFITS
- Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget
- Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews
- Flexibility: work 100% remotely with flexible hours that support focus, autonomy, and a healthy work rhythm
- Meaningful, modern projects: build impactful products using modern technologies alongside global teams and leading brands
- Collaborative culture: join a supportive environment with zero micromanagement where ideas are welcomed and contributions are recognized
- Well-being & support: access local well-being programs and people-focused support tailored to your location
