Flo is the world’s #1 health & fitness app on a mission to build a better future for female health. We are looking for a Cloud Security Engineer to join Velocity, our Internal Platform team. Your mission is to ensure that every system, pipeline, and tool our engineers rely on is secure by default.
The Scale of the Challenge
At Flo we don't just have users, we have a global community. When millions of people trust you with their most personal health data, security isn't a feature — it's a foundation.
The Mission: Velocity
The Velocity team exists to eliminate friction. We build and own the foundation everything else runs on: cloud infrastructure, developer tooling, and SRE practices.
What You Will Do
- Cloud Security Posture: Own and continuously strengthen Flo's AWS security posture using tools like GuardDuty, Inspector, Security Hub, and SSM Patch Manager.
- Container & Supply Chain Security: Harden container image security end-to-end — patch vulnerabilities automatically with Copacetic, sign and verify images with Cosign/Sigstore, and enforce policies at admission with Kyverno.
- Policy as Code: Manage CI/CD security across the organisation using policy-as-code tooling (Kyverno, Checkov), ensuring standards are enforced programmatically.
- Security Observability: Build visibility into security performance by measuring and visualising actionable metrics using tools like Databricks Dashboards or Looker.
- High-Scale Privacy: Support the infrastructure for industry-leading privacy features, such as our TIME-recognised "Anonymous Mode."
- Culture & Thought Leadership: Shape Flo's broader security culture through proactive engagement, documentation, and cross-team collaboration.
What You Bring
- 7+ years in Infrastructure Security, Cloud Security, or Security Engineering roles.
- Deep expertise in AWS security services and best practices is essential.
- Proficient in Terraform and Terragrunt — you run everything as code.
- Strong knowledge of Kubernetes security, image hardening, and admission control.
- Solid understanding of identity management principles — SSO, OAuth, JWT, SAML.
- Comfortable scripting in Python, Bash, or similar to automate security workflows.
- Understanding of modern network security principles and their practical application.
- Experience building Secure Software Development Lifecycle phases into engineering workflows.
Bonus Points
- Experience with security monitoring and event correlation systems (IDS/IPS, SIEM, AWS-native tooling).
- Knowledge of Zero Trust Architecture and its implementations (e.g., Cloudflare).
- Familiarity with secret management processes and tools.
- Experience in multi-cloud environments (AWS and preferably GCP).
- Understanding of business continuity principles (BIA, DRP).
- Professional accreditations such as AWS Security Specialty, CKS, or CISSP.
Why Join Flo?
- Your work directly protects the health data of millions.
- We hire experts and empower you to deliver.
- Work with modern security tooling deployed on real production infrastructure at massive scale.
