Security Engineer, Application Security - GameChanger

About GameChanger:

We believe in the life-changing impact youth sports have on and off the field. Sports encourage leadership, teamwork, responsibility, and confidence—important life lessons that have the power to propel our youth toward meaningful futures. We recognize that without coaches, parents, and volunteers, organized youth sports could not exist. By building the first and best place to experience the youth sports moments important to our community, we are helping families elevate the next generation through youth sports.

So if you love sports and their community-building potential, or building cool products is your sport, GameChanger is the team for you. We are a remote-first, dynamic tech company based in New York City, and we are solving some of the biggest challenges in youth sports today.

The Position:

We’re looking for a Security Engineer to join our InfoSec team and become the primary security partner for our software engineering organization. Reporting to the Security Engineering Manager, you’ll operate application security across the SDLC, champion secure design and development practices, and bring DevSecOps discipline to how we build and ship software. This is a high-impact, highly collaborative role. You’ll work closely with platform and product engineers to make security a part of how we build and deliver. You will also be a member of our weekly on-call rotation.

What You’ll Do:

Application Security

• 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.

DevSecOps

• 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.

Vulnerability & Risk Management

• 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.

What You’ll Bring:

• 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).
• Beneficial certifications: AWS Certified Security Specialty, CKS, GWEB, GMOB, or equivalent.

Who You Are:

• 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.
• 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 proactively address root causes.
• Collaborative and cross-functional: You bring product, business, and operational context into your security decisions.
• Approachable: You foster open dialogue and make it easy for engineers to surface security concerns without fear of judgment.
