Security Engineer - Dallas - Associate

Goldman Sachs•Dallas, TX

About The Position

Led by the Chief Information Security Officer (CISO), Technology Risk at Goldman Sachs is responsible for securing the firm against cyber threats, detecting and preventing intrusions, developing secure applications and infrastructure, and measuring cybersecurity risk. The Advisory arm within Technology Risk provides consultative and technology subject matter expertise, assessing new technology initiatives for risk, partnering with engineers to design secure products, embedding security reviews in the SDLC, and guiding technology innovation. This team is crucial in designing and assessing controls for the firm's transition to native public cloud applications. The role involves performing software architecture design reviews for on-premise or cloud deployments, particularly focusing on AWS. The Security Engineer will act as an Application security liaison for developers and architects, review security assessment reports from penetration testing and code reviews, and conduct read-out calls to communicate risks and recommend mitigation strategies. Additionally, the position requires developing secure architecture design patterns for cloud-native applications on AWS, leveraging AI/LLM-driven tools to enhance security review workflows, and mentoring junior team members.

Requirements

3 or more years’ experience in one or more technical roles (focusing on application security and cloud security).
Prior experience in performing Threat Modeling or Secure Design Reviews or Secure Architecture Reviews.
Knowledge of most common Application Security vulnerabilities - e.g., OWASP Top 10 and cloud security gaps.
Familiarity with Security standards such as OWASP Testing Guide, OWASP ASVS, NIST, and SANS Top 20.
Common security controls and how they apply to different designs and systems, including but not limited to secure authentication, access controls, encryption (at rest/in transit), IDS/IPS, DLP, malware, etc.
Experience in application vulnerability assessment and penetration testing of web, thick-client, or mobile applications.
Working knowledge of application security tools such as fuzzers, scanners, debuggers, decompilers, proxies, simulators, etc.
Familiarity with modern and common web stack technologies (e.g., HTTP, HTML5, AJAX, REST, etc.) and platforms (e.g., DropWizard, Spring Boot, AngularJS, React, Tomcat, .Net, Sybase, MS SQL, MongoDB, etc.).
Familiarity with common cloud services, recommended security best practices, and secure deployment patterns. AWS is preferred.
Understanding of core cryptography concepts (Encryption, Hashing, HMAC, digital signatures) and how they are applied and attacked in web applications (e.g., TLS attacks, CBC attacks).
Ability to analyze protocols (OAuth, SAML, OIDC), flows, and interactions in a system design to evaluate gaps.
Ability to identify threats, abuse cases, and gaps in the design before it is implemented.
Good written and oral communication to be able to articulate risks to both technical and management stakeholders.
