Job description

500M+ downloads. 80M+ monthly users. A decade of building – and we’re still accelerating.

Flo is the world’s #1 health & fitness app worldwide on a mission to build a better future for female health. Backed by a $200M investment led by General Atlantic, we became the first product of our kind to reach a $1B valuation in 2024 – and we’re not slowing down.

With 7M paid subscribers and the highest-rated experience in the App Store’s health category, we’ve spent 10 years earning trust at scale. Now, we’re building the next generation of digital health – AI-powered, privacy-first, clinically backed – to help our users know their body better.

The Job

As a key member of Flo’s Security Architecture team, you will lead the design and operation of our US Healthcare security controls. You'll work directly with Product and Engineering teams to translate HIPAA and SOC 2 requirements into technical security controls across Flo's AWS multi-account environment - including EKS, Lambda, RDS, S3, VPC networking, IAM, and KMS.

You’ll own the roadmap for HIPAA compliance and SOC 2 Type II certification, working closely with external auditors and professional services partners, and partnering with Engineering and Legal to build a secure, compliant platform for millions of users.

Your Experience

Must have:

• 7+ years in security, compliance, or risk management (3+ in a leadership capacity), with a Bachelor's degree in a related field or equivalent experience.
• Deep expertise in SOC 2 within the AWS environment (familiarity with HIPAA frameworks would be considered a big plus).
• Familiarity with PHI handling, GRC and compliance automation platforms, and exposure to enterprise architecture frameworks such as TOGAF.
• Strong ability to manage multiple concurrent audit and certification workstreams.
• Excellent written and verbal communication, with the ability to translate complex compliance requirements into clear actions for engineering and business teams.

Nice to have:

• CISA, CISM, or CISSP certifications
• Experience with NIST 800-53, Cloud Security Alliance (CSA), and Center for Internet Security (CIS) frameworks
• Experience in healthcare or another regulated industry; HITRUST experience a plus
• Experience building compliance roadmaps in early-stage startups
• Exposure to containerization (Docker/Kubernetes), serverless, and big data platforms
• Exposure to DevSecOps and sprint-based Agile development

What you'll be doing

You'll be responsible for:

• Compliance Leadership: Lead annual SOC 2 and HIPAA certifications, managing interfaces with external auditors and professional services.
• Technical Control Design: Partner with Engineering to harden AWS workloads (EKS, EC2, data pipelines, and more) to meet HIPAA and SOC 2 controls; perform technical security design reviews and architectural risk assessments for services handling PHI.
• Policy & Risk: Define and maintain security policies and standards; embed risk assessment activities within engineering processes, and evolve Flo’s security risk management framework.
• Vendor Risk Management: Support vendor risk activities including contract reviews and security posture assessments.
• Operational Excellence: Partner with control owners to automate evidence gathering and ensure controls reduce friction rather than creating it.
• Stakeholder Management: Serve as the primary Security POC for US regulators and partners; support the wider Security team with ISO 27001/27701 alignment; report risk status to security leadership.
• Tooling: Manage and integrate GRC and compliance automation platforms to streamline monitoring and reporting.

What You’ll Get

We support impact with meaningful reward. Here’s what that looks like:

• Competitive salary and annual reviews
• Opportunity to participate in Flo’s performance incentive scheme
• Paid holiday, sick leave, and female health leave
• Enhanced parental leave and pay for maternity, paternity, same-sex and adoptive parents
• Accelerated professional growth through world-changing work and learning support
• In-person collaboration and work in a hybrid model, with 3 days per week spent in the office
• 5-week fully paid sabbatical at 5-year Floversary
• Flo Premium for friends & family, plus more health, pension and wellbeing perks
