Job Description

The D. E. Shaw & Co., L.P. Information Security team in the Systems group is hiring a hands-on Application Security Engineer to work as an individual contributor. In this role, you will partner closely with developers to design secure solutions and build automated, AI-enabled application security workflows and guardrails that help teams move faster with confidence.

What You’ll Build and Operate

Design, build, and operate agentic security workflows that continuously review code changes, leveraging existing analyzers and custom analysis to investigate findings and propose fixes.
Create evaluations, feedback loops, and guardrails to assess false positives, missed vulnerabilities, and the safety of proposed fixes, using known test cases and expert review.
Use OIDC and other web security concepts to inform secure identity and access handling as part of application and workflow design.

How You’ll Support Secure Shipping

Lead security and design reviews for new and existing software, collaborating directly with developers to surface vulnerabilities and recommend practical remediation.
Embed secure coding practices alongside development teams to strengthen the Secure Development Lifecycle (SDLC).
Represent Information Security to engineering teams, translating findings into clear, actionable guidance for technical stakeholders and, when needed, non-technical stakeholders.

Agentic AI Security, Up Close

Help secure the firm’s use of agentic AI by assessing how developer agents and internal AI platforms handle identity, data access, and tool execution.
Bring fluency in AI-enabled engineering work, including the risks associated with agentic applications and experience using AI SDKs to build applications or agents.

Qualifications

5+ years of experience in application security, product security, security engineering, or software engineering with a strong security focus.
Bachelor’s degree in computer science or a related technical discipline (advanced degrees in relevant specialties, such as cryptography, are welcome).
Advanced knowledge of web application security fundamentals, including web protocols, authentication and identity standards (e.g., OIDC), browser security behavior, and applied encryption basics.
Proven track record building security software such as product features, internal tools, custom scanners, or analysis capabilities, rather than only deploying or operating off-the-shelf tools.
Hands-on experience finding and mitigating vulnerabilities in complex systems through secure design review, code review, or penetration testing.
Familiarity with modern software development practices and workflows.
Sound judgment and clear communication, with the ability to make security decisions independently.

Compensation and Benefits

USD 225,000 - 300,000 per year
Variable compensation via a year-end bonus, guaranteed in the first year of hire
Medical and prescription drug coverage
401(k) contribution matching
Wellness reimbursement
Family building benefits
Charitable gift match program
