Security Engineer, Application Security

GameChanger is a remote-first technology company focused on improving youth sports experiences for families and communities. The Security Engineer will serve as the primary security partner for software engineering, operating application security across the SDLC, advancing DevSecOps practices, managing application vulnerabilities and risks, and supporting secure cloud and product development.

Responsibilities:

• Embed security into every phase of the SDLC
• Champion security requirements for the responsible and secure integration of Gen AI and agentic AI tools within our product stack
• Conduct security-by-design engagements for new features, APIs, platform initiatives, and infrastructure changes
• Perform secure code reviews providing engineers with clear, actionable findings and remediation guidance
• Partner with architecture and platform teams to establish secure API patterns (REST and GraphQL)
• Contribute to and maintain secure coding guidelines, API security standards, and security architectural patterns that serve as the “paved roads” for all engineering teams
• Give useful code review feedback, write documentation that outlasts the ticket, and run the occasional workshop or lunch-and-learn for engineers
• Integrate and maintain security tooling across CI/CD pipelines
• Enforce security quality gates in delivery pipelines
• Harden the CI/CD platform components, including configuration and hardening of GitHub Actions and runner environments
• Identify opportunities to leverage AI for increasing engineering productivity and agentic security workflows
• Work alongside DevOps engineers to ensure cloud infrastructure is defined and deployed securely via IaC (terraform, k8s)
• Implement and validate security controls for containerized workloads
• Support the implementation of application-layer network security controls, such as Web Application Firewalls (WAFs) and CDN security, to protect application endpoints
• Operate the application vulnerability management lifecycle
• Triage and prioritize findings from our sources (including; GHAS, NowSecure, Wiz, BugCrowd, penetration tests) by business impact and exploitability
• Proactively identify systemic risks and facilitate cross-functional initiatives to address root causes
• Track security-specific KPIs (e.g., MTTR, vulnerability density, and security coverage of CI/CD pipelines) and translate them into actionable insights for engineering and business leadership
• Effectively communicate security risk clearly to both engineering and business leaders

Requirements:

• 3+ years in application security engineering
• Proven experience building and operating internal security developer platforms or tooling that reduces developer friction
• Demonstrated ability to use AI/ML-driven tools to enhance security effectiveness and scalability
• Hands-on experience leading threat modeling engagements and designing paved roads
• Proven track record integrating security tooling into CI/CD pipelines
• Working knowledge of OWASP Top 10s (web, mobile, API, LLM)
• Hands-on experience securing deployments in AWS with container and Kubernetes security, IaC scanning, and policy-as-code approaches
• Demonstrated expertise in security-by-design in TypeScript, Swift, and/or Kotlin
• Track record of implementing secure primitives in mobile ecosystems (iOS/Android)
• Pragmatic defender. You understand that security must enable the business, not block it. You look for “secure by default” solutions and know how to make the right path the easy path for engineers
• Force multiplier. You don't solve every security problem yourself. You coach, document, and build systems that make the engineers around you more secure by default
• Clear communicator. You can trace a BOLA vulnerability chain to a frontend engineer and translate the same risk into business terms for a VP; and you know which conversation you're in
• Automation-first. If you have to do it twice, you'd rather write the script
• Long-view oriented. You think about medium-to-long-term system health, not just the current sprint, and you proactively address root causes rather than patching symptoms repeatedly
• Collaborative and cross-functional. You bring product, business, and operational context into your security decisions, not just security best practices in isolation
• Approachable. You foster open dialogue, encourage diverse perspectives, and make it easy for engineers to surface security concerns without fear of judgment or friction
• Beneficial certifications: AWS Certified Security Specialty, CKS, GWEB, GMOB, or equivalent
