Senior Cloud & Application Security Engineer

AXON-Networks•Irvine, CA

About The Position

The Senior Cloud & Application Security Engineer is the primary hands-on technical security engineer within AXON Networks’ Information Security organization. The role partners with Software Engineering, Cloud Operations, Platform Engineering, DevOps, QA, and Product teams to identify security weaknesses, design practical controls, validate remediation, improve development security practices, and strengthen AXON’s cloud-native platforms. The engineer works across source code, CI/CD pipelines, Kubernetes clusters, cloud infrastructure, APIs, identity systems, vulnerability findings, architecture diagrams, and production environments. The role supports engineering teams with security expertise, technical assurance, tooling, standards, testing, and guidance; it does not replace Engineering ownership of secure software and infrastructure. Responsibilities include application security, DevSecOps and software supply chain security, cloud and Kubernetes security, vulnerability management, security architecture and testing, detection and incident response, and technical support for Security Champions.

Requirements

5+ years of experience in application security, cloud security, security engineering, DevSecOps, penetration testing, platform engineering, or related technical roles.
Strong knowledge of cloud-native application architectures.
Strong practical knowledge of Kubernetes and containers.
Understanding of CI/CD pipelines and modern software development workflows.
Experience with application security testing tools, including SAST, SCA, container scanning, dependency scanning, and secret detection.
Strong understanding of common application vulnerabilities and secure coding practices.
Experience evaluating REST APIs, service-to-service communications, authentication, authorization, and secrets handling.
Experience with at least one major public cloud platform.
Ability to analyze vulnerabilities and determine realistic exploitability and impact.
Ability to communicate effectively with developers and infrastructure engineers.

Nice To Haves

Experience with Go, Java, Python, C/C++, or other languages used in cloud-native environments.
Experience with GitLab Ultimate security functionality.
Experience with Terraform, Helm, Kubernetes operators, or infrastructure-as-code.
Experience with Azure, GCP, or OCI.
Familiarity with service meshes, gRPC, message buses, distributed systems, and microservice architectures.
Familiarity with OWASP ASVS, OWASP Top 10, CWE, CVSS, EPSS, KEV, and related vulnerability frameworks.
Experience with security testing tools such as Burp Suite, Nmap, Semgrep, Trivy, or equivalent tools.
Relevant certifications such as OSCP, CSSLP, CCSP, GIAC, Kubernetes security certifications, or equivalent practical experience.

Responsibilities

Partner with development teams to improve secure coding and application security practices.
Review findings from SAST, SCA, dependency scanning, container scanning, secret detection, and other security tools; help teams assess exploitability, exposure, severity, and remediation.
Perform targeted manual security reviews of applications, APIs, and services, and participate in application and architecture threat modeling.
Help define secure API design and input validation requirements; review authentication, authorization, session management, cryptography, and secrets handling.
Support penetration testing and validate remediation of penetration test findings.
Integrate and improve security controls in CI/CD pipelines, including security gates and automated testing.
Improve source code, dependency, container, and artifact security; assist with artifact integrity, signing, provenance, and software supply chain controls.
Evaluate build and deployment workflows for security weaknesses and help define security controls that avoid unnecessary development friction.
Assess Kubernetes clusters, workloads, cloud environments, and supporting infrastructure for security weaknesses.
Review identity and access management, network security, segmentation, ingress and egress controls, workload identities, service-to-service access, container runtime configuration, secrets management, and image security.
Support implementation and validation of cloud security baselines, review infrastructure-as-code, and partner with Cloud Operations and Platform Engineering on secure architecture.
Analyze vulnerabilities affecting AXON software, infrastructure, containers, dependencies, and services; evaluate newly disclosed CVEs for applicability and exposure.
Assist the Information Security Analyst and Engineering teams with vulnerability triage, validate remediation where appropriate, distinguish theoretical scanner findings from meaningful exploitable risk, and document findings and recommendations.
Participate in design and architecture reviews, identify risks early, recommend practical controls and architectural improvements, and review new technologies, platforms, integrations, and services for security implications.
Help maintain approved security patterns and reference architectures.
Conduct targeted security testing of applications, APIs, cloud services, infrastructure, and configurations; develop repeatable validation procedures and automation where appropriate.
Coordinate with external penetration testing providers, reproduce security findings, verify fixes, and help teams develop security-focused test cases.
Assist with technical investigation of suspected security incidents by reviewing logs, cloud events, authentication activity, network activity, and system evidence.
Help improve security telemetry and detection capabilities, and participate in incident response exercises and post-incident reviews.
Provide technical guidance and mentorship to Security Champions, develop technical security training, participate in Security Champion Council meetings, help Champions evaluate findings, and promote reusable secure engineering patterns.
