Discretionary
Our team operates at the forefront of innovation, vigilance, and strategic risk management. We combine deep industry expertise with advanced analytics and a disciplined approach to proactively identify and mitigate emerging threats across the organization. Through continuous monitoring, comprehensive assessments, and strong cross-functional partnerships, we deliver tailored security solutions that strengthen BOKF’s resilience.
We are passionate about advancing security maturity across the enterprise—collaborating closely with teams to provide actionable insights, champion best practices, and enhance controls. Our work empowers BOKF to pursue its strategic goals with confidence in an evolving threat landscape.
As an Application Security Engineer III, you will play a key leadership role in advancing BOKF’s application security posture. You will drive the implementation and optimization of security capabilities across the Application Protection portfolio, including WAF, API security, DAST, SAST, IaC, SCA, and SIEM/SOAR.
In this role, you will lead threat modeling and vulnerability assessments for internally developed applications and APIs, design and implement custom security policies and controls, and guide the response to application-layer incidents. You will serve as a subject matter expert, mentoring junior engineers while contributing to the design of advanced detection and prevention strategies.
You will stay ahead of evolving threats—including OWASP Top 10 risks, API vulnerabilities, and software supply-chain attacks—and apply that knowledge to strengthen defenses. The role also includes performing forensic and root cause analysis, partnering with risk, legal, and compliance teams to support regulatory requirements, and developing custom code to enhance application security capabilities.
As BOKF embraces AI-enabled development and security tooling, you will leverage approved AI capabilities to accelerate workflows while ensuring accuracy, safeguarding sensitive data, and maintaining strong governance. You will also assess and mitigate risks associated with AI/LLM-enabled applications and third-party services, including prompt injection, data leakage, and insecure integrations, while helping implement effective monitoring and controls.
Our team thrives in a dynamic and collaborative environment where curiosity, ownership, and continuous improvement are foundational. We encourage innovative thinking, open knowledge-sharing, and proactive problem-solving.
By working together to address complex security challenges, team members are empowered to expand their expertise, influence meaningful outcomes, and shape the future of application security at BOKF. Our strong partnerships across the organization and commitment to excellence ensure we remain resilient and forward-looking.
