Senior Infrastructure Security Engineer

Denver, CO

About This Role

Strava is the app for active people. With over 150 million athletes in more than 185 countries, Strava is where connection, motivation, and personal bests thrive. No matter your activity, gear, or goals, we help you find your crew, crush your milestones, and keep moving forward. Start your journey with Strava today.

Our mission is simple: to motivate people to live their best active lives. We believe in the power of movement to connect and drive people forward.

At Strava, we protect the infrastructure that powers millions of athletes' journeys. As a Senior Infrastructure Security Engineer on the Foundation Team, you'll be the guardian of our platform—building security into every layer of our infrastructure while enabling teams to move fast and innovate fearlessly. You'll balance security excellence with developer velocity, ensuring our platform remains both impenetrable and performant.

The Foundation Team is the backbone of Strava's engineering organization, providing the secure infrastructure, tools, and frameworks that power every feature our athletes love. In this role, you'll embed security into the foundation of our platform—from hardening our Kubernetes clusters and cloud infrastructure to building automated security guardrails that make the secure path the easy path for developers.

By architecting security solutions that scale, you'll protect the data of 150+ million athletes while enabling product teams to ship features with confidence. You'll be both a builder and a defender—creating tools that empower engineers, responding to emerging threats, and partnering with teams across Strava to weave security into our engineering DNA.

We follow a flexible hybrid model that translates to more than half your time on-site in our Denver office — three days per week.

What You'll Do:

  • Design and implement security controls across Strava's cloud infrastructure, including network segmentation, IAM policies, and data protection mechanisms
  • Lead security initiatives for the Foundation Team, conducting threat modeling, security reviews, and risk assessments for infrastructure changes
  • Build and maintain security automation tools that enable engineering teams to deploy securely by default
  • Partner with engineering teams to integrate security best practices into CI/CD pipelines and infrastructure-as-code workflows
  • Respond to security incidents, perform root cause analysis, and implement preventive measures to strengthen our security posture
  • Develop and maintain security monitoring, alerting, and response systems using SIEM and cloud-native security tools
  • Drive compliance initiatives, ensuring infrastructure meets SOC2, GDPR, and other regulatory requirements
  • Collaborate with the security team to implement zero-trust architecture and strengthen our defense-in-depth strategy
  • Participate in on-call rotations and mentor other engineers on security best practices

What You'll Bring to the Team:

  • 5+ years of infrastructure engineering experience with at least 3 years focused on security engineering or DevSecOps
  • Deep expertise in AWS security services (IAM, GuardDuty, Security Hub, WAF, Shield) and cloud security best practices
  • Strong background in Kubernetes security, including RBAC, network policies, admission controllers, and container security
  • Proven experience implementing infrastructure-as-code security patterns using Terraform, with expertise in policy-as-code tools
  • Track record of building security automation and tooling that scales across large engineering organizations
  • Excellence in cross-team collaboration, with the ability to influence security practices without direct authority
  • Strong incident response experience and ability to remain calm under pressure during security events

Some of our Technical Expectations:

We're not looking for 100% coverage; if you match any of these qualifications, we'd love to hear from you:

  • Experience with security scanning tools (Trivy, Snyk, SonarQube) and vulnerability management workflows
  • Experience in secrets management solutions (HashiCorp Vault, AWS Secrets Manager) and PKI infrastructure
  • Experience with SIEM platforms (Splunk, Datadog Security, Elastic Security) and security orchestration
  • Strong knowledge of network security including VPC design, service mesh (Istio), and zero-trust networking
  • Familiarity with compliance frameworks and experience with security audits (SOC2, ISO 27001, PCI-DSS)

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
