Application Security Engineer III
Our Technology Team partners with teams across Expedia Group to create innovative products, services, and tools to deliver high-quality experiences for travelers, partners, and our employees. A singular technology platform powered by data and machine learning provides secure, differentiated, and personalized experiences that drive loyalty and traveler satisfaction.
Our Product Security organization is on a mission to transform how cybersecurity is built and delivered at Expedia Group. We are building the security infrastructure, platforms, and services that empower our engineering teams to ship products faster — with security embedded by default, not bolted on after the fact. We believe that great security accelerates product velocity, and we are looking for a deeply technical, hands-on individual contributor who will help us architect and realize that vision at scale. If you are passionate about reimagining what a modern product security organization looks like — and have the technical depth to make it real — this role is for you.
In this role, you will:
Drive shift-left security practices by embedding security requirements and controls throughout the software development lifecycle, from design through deployment.
Integrate, maintain, and continuously improve security tooling and automation across CI/CD pipelines, including capabilities such as SAST, DAST, SCA, dependency scanning, and software supply chain protections.
Configure, tune, and triage security tools and vulnerability management platforms to reduce false positives, improve signal quality, and strengthen remediation workflows for developers.
Partner closely with product, engineering, platform, privacy, compliance, infrastructure, and security stakeholders to identify, assess, and remediate application security risks across the services and components you support.
Conduct threat modeling, security code reviews, and system design reviews, including low-level design, API design, and data modeling, for new and existing features and services.
Safely integrate and operate AI/ML-enabled solutions that improve security outcomes, applying familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products.
Minimum Qualifications:
Bachelor’s degree in Computer Science or a related technical field; or equivalent related professional experience.
5+ years of relevant professional experience.
Experience in application security, product security, DevSecOps, or security engineering supporting modern CI/CD pipelines, cloud-native services, and secure software delivery practices across multiple services or domains.
Practical experience with software supply chain security, including areas such as SBOMs, signing or attestation, secure build pipelines, and using SAST, DAST, and SCA to protect against open-source and supply chain risks.
Practical experience operating and tuning vulnerability management and security tooling platforms (e.g., Qualys, SCA, Wiz, GHAS, Ox security, integrating them with CI/CD pipelines (e.g., GitHub Actions, Jenkins, Spinnaker), ticketing systems, and developer workflows, and using modern programming languages such as Java or Python to automate security outcomes.
Preferred Qualifications:
Experience applying AI/ML and agentic AI techniques to vulnerability management, including autonomous triage workflows, intelligent prioritization, classification, enrichment, or AI-assisted security tooling that improves detection, prioritization, and remediation effectiveness.
Familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real-world products, including a working understanding of AI/ML security implications such as the OWASP LLM Top 10 and basic penetration testing concepts.
Demonstrated success enabling developers on secure development practices and influencing secure engineering decisions within a team, product area, or domain through practical guidance, standards, and playbooks.
Strong communication skills with the ability to distill complex security topics for broad technical and non-security audiences, operate effectively in fast-paced environments, and navigate ambiguity with sound judgment.
Proven impact reducing vulnerability backlogs and improving remediation SLAs through automation, tool tuning, stronger signal-to-noise ratios, and data-driven operational improvement.
Starting pay for this role will vary based on multiple factors, including location, available budget, and an individual’s knowledge, skills, and experience. Pay ranges may be modified in the future.
