Cybersecurity Engineer IV – Application Security

Location: Chicago, IL | Peoria, IL | Dallas, TX

Work Model: Hybrid (Currently onsite every Wednesday; role is expected to transition to 5 days/week onsite. Candidates must be local and willing to work onsite full-time when required.)

Duration: Duration: 12 months

Important Notes

•            This is an Application Security position, not a general Cybersecurity role.

•            Candidates with backgrounds focused primarily on Network Security, SOC Operations, Infrastructure Security, or traditional Cybersecurity without significant Application Security experience are unlikely to be a strong fit.

•            Experience collaborating directly with software development teams and integrating security throughout the SDLC is essential.

Position Overview

Caterpillar is seeking an experienced Cybersecurity Engineer IV specializing in Application Security to join its Security Engineering team. This is not a general cybersecurity role—the primary focus is embedding security throughout the Software Development Lifecycle (SDLC) while partnering directly with software engineering teams.

The selected candidate will support external-facing, revenue-generating eCommerce and web applications, ensuring security is integrated from application design through deployment and production. This position is ideal for security professionals who have experience working alongside developers to build secure applications rather than performing security assessments after development is complete.

About the Team

The Security Engineering team partners closely with Caterpillar''s eCommerce Development organization to integrate security into every phase of application development. Engineers work directly with software developers, architects, and technical leaders to improve secure coding practices, identify vulnerabilities early, and implement scalable security solutions throughout the SDLC.
