Sets application security direction and standards across engineering teams. Builds scalable security tooling, automation, and observability; leads threat modeling, risk assessments, code reviews, and multi-team remediation. Develops strategies for AI-powered systems and agentic development risks, API security, and software supply chain security. Partners with engineering and security teams, prioritizes investments, communicates risk to leadership, and mentors AppSec engineers.

The Security Engineer role involves identifying vulnerabilities, automating tasks in penetration testing, and creating security reports for various audiences.

Build and scale enterprise application security capabilities: design automations, integrations, developer tooling, golden paths, and secure AI guardrails. Secure code, dependencies, containers, IaC, CI/CD, and software supply chains; improve vulnerability triage, remediation, telemetry, and platform integrations while mentoring engineers and partnering with cloud and platform teams.

Partner with engineering, compliance, and security teams to embed application security into the SDLC: triage static/SCA alerts, advise on OWASP Top 10 remediation, maintain developer playbooks and training, track security metrics and evidence for audits, and help shape AI governance and GenAI-safe workflows.

Own and evolve the application security program: embed secure SDLC practices, partner with engineering on design and code reviews, manage AppSec tooling (SAST/DAST/ASM/WAF/mobile), harden AWS deployments, integrate security into CI/CD, and lead vulnerability investigation and remediation efforts.

Own the organization’s application security posture, partnering with engineering and IT on secure coding, vulnerability management, penetration testing, security architecture, and remediation. Support audits, risk assessments, SOC 2 compliance, incident and breach investigations, bug bounty programs, and employee security training. The role is fully remote but requires a final in-person interview with company-paid travel.

Secure Temporal’s development pipeline, product, and customer execution environments. Partner with engineering teams on secure architecture, threat modeling, risk assessments, code and software supply-chain security, vulnerability triage, Kubernetes hardening, multi-tenant isolation, and responsible AI security. Participate in on-call rotations and help establish actionable security policies and practices across the organization.

Secure applications throughout the software development lifecycle by performing SAST, DAST, penetration testing, secure code reviews, vulnerability remediation tracking, and DoD security control validation. The role uses Fortify and SonarQube, produces assessment reports, supports secure SDLC process design, and partners with developers, architects, and cybersecurity specialists.

Secures applications throughout the software development lifecycle by performing SAST with Fortify, code analysis with SonarQube, DAST, penetration testing, secure code reviews, vulnerability remediation tracking, and DoD control validation. The role documents assessment findings, supports secure SDLC process design, and collaborates with developers, architects, and cybersecurity specialists. Requires an active Secret or TS clearance, application security experience, penetration testing knowledge, and CEH certification. Quarterly travel to Scott Air Force Base is required.

Embeds application security into the SDLC through DevSecOps processes, security assessments, repository scanning, vulnerability triage, remediation validation, and secure code review. Uses tools such as Burp Suite, CodeQL, SAST, SCA, and secret scanning across applications, APIs, cloud workloads, and infrastructure. Develops security metrics and executive dashboards, coaches development teams, participates in Agile ceremonies, and promotes secure coding and responsible AI-assisted security practices.

Lead AppSec efforts across product, platform, and AI features by owning secure SDLC, performing threat modeling and deep code reviews, driving vulnerability management and remediation, building AppSec tooling and automations (including AI-assisted workflows), and enabling engineering teams with secure design guidance and training.

Build and advance application and product security across the engineering organization. Responsibilities include establishing secure defaults, CI guardrails, security requirements, threat modeling, risk assessments, penetration testing, vulnerability remediation, secure coding education, roadmap ownership, and hands-on code review. The role partners closely with product, engineering, DevOps, and services teams to secure applications, microservices, and AI features while enabling efficient development.

Operate application security across the SDLC, including secure design, code reviews, threat modeling, API security, DevSecOps tooling, CI/CD security gates, cloud and container security, vulnerability management, and risk communication. Partner with engineering teams on secure coding standards, AWS, Kubernetes, Terraform, mobile ecosystems, and responsible AI integration. Participate in an on-call rotation and develop scalable security platforms, paved roads, documentation, and developer training.

The Senior Application Security Engineer ensures the security of systems and data by monitoring vulnerabilities, responding to incidents, and promoting security best practices within the organization.

Lead security initiatives by establishing secure development practices, conducting security reviews, as well as managing threat modeling and security assessments.

Lead application security for products by performing threat modeling, manual secure code reviews, and penetration testing. Collaborate with engineers to remediate defects, build AppSec automation and tooling, secure cloud/containerized applications, and drive bug-bounty responses to harden platform security.
