Truist•Atlanta, GA

About The Position

Serves as an advanced technical specialist in Dynamic Application Security Testing (DAST), designing, configuring, and improving testing capabilities for complex web applications and APIs across the software development lifecycle. Applies deep application security expertise to execute and validate assessments, solve difficult testing conditions, and develop reusable technical solutions that improve scan accuracy, coverage, reliability, and scalability. Works independently with limited supervision and serves as a technical authority for DAST standards, assessment patterns, and tooling within the Security Engineering department or job area.

Requirements

Bachelor’s degree or equivalent education, training, and work-related experience.
Minimum of 5 years of experience in security engineering or related cybersecurity roles.
Advanced knowledge of cybersecurity principles, theories, and concepts.
Proven experience in software development lifecycle security practices.
Advanced knowledge of threat modeling, security testing, and penetration testing.
Experience implementing and managing complex information security technologies.

Nice To Haves

Advanced cybersecurity certification such as CISSP, CSSLP, GIAC, GWAPT, OSWE, or an equivalent application security credential.
Deep hands-on experience with enterprise DAST technologies and methodologies for complex web applications and APIs.
Advanced experience with authenticated testing, modern authentication protocols, session management, multifactor authentication, scripted login workflows, and credential handling.
Deep working knowledge of HTTP, browser behavior, web and API architectures, authentication and authorization patterns, API specifications, and common application frameworks.
Experience with security automation, APIs, scripting, data transformation, orchestration, CI/CD integrations, or workflow technologies.
Familiarity with emerging cybersecurity technologies, industry trends, and strategic risk management.

Responsibilities

Design, configure, test, and improve advanced DAST solutions and technical patterns for complex web applications and APIs.
Perform and validate complex authenticated assessments, including login success, session state, crawl coverage, attack surface coverage, vulnerability results, and overall assessment validity.
Engineer DAST scan policies, authentication workflows, login sequences, session handling, API definitions, custom scripts, integrations, and automation for reliable and repeatable testing.
Investigate difficult and undefined assessment problems, including multifactor authentication constraints, incomplete crawling, blocked requests, dynamic application behavior, tool limitations, false positives, false negatives, and inconsistent results.
Use browser, proxy, HTTP, API, logging, and diagnostic techniques to identify root causes and develop practical, reusable technical solutions.
Analyze and document DAST evidence to distinguish validated vulnerabilities, suspected false positives, coverage limitations, and inconclusive results, and support remediation verification.
Partner with application and engineering teams to understand runtime behavior, resolve testability constraints, and establish technically appropriate DAST configurations without assuming ownership of application readiness.
Serve as a technical escalation point, review complex configurations and technical evidence, and share specialized knowledge through peer reviews, troubleshooting sessions, and reusable documentation.
