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. Now, we’re building the next generation of digital health - AI-powered, privacy-first, clinically backed - to help our users know their body better.

As our Engineering Manager for the AI Platform, you will lead the core team that builds the shared infrastructure powering every AI feature at Flo—from our chatbot and cycle predictions to personalized health insights. We don’t just use AI; you will work in an environment where we maintain direct technical partnerships with Databricks, OpenAI, Anthropic, and AWS, moving far beyond standard vendor relationships.

The AI Platform team is embedded directly in product delivery, working in cross-functional squads alongside our Data Platform team and external model partners. We operate with a clear but fluid strategy — iterating quickly based on rapid AI/LLM advancements and real-time metrics. You will manage a dynamic environment where roughly 30% of the team's work is reactive, driven by immediate product needs, while maintaining focus on our long-term roadmap.

You’ll provide the management layer that supports their technical execution, performance, and career growth. You’ll help the team maintain high standards for safety, medical compliance, and performance.

• Cross-Functional Impact: Act as the primary point of contact for stakeholders across Product, Analytics, and Engineering, while representing Flo’s AI vision to our industry partners.
• Engineering Leadership: Proven track record managing engineering teams in fast-moving product environments. You know how to build high-performing teams, mentor talent, and hire effectively.
• AI/ML Infrastructure Depth: You have direct, hands-on experience leading or building ML systems in production. You understand MLOps, model serving, or AI platform engineering.
• The "Manager-as-Leader" Mindset: You aren't looking to spend your day coding, but you have the technical depth to participate in architecture discussions and credibly guide technical trade-offs.
• Agile & Stakeholder Savvy: You are comfortable operating where priorities shift. You know how to protect roadmap momentum while absorbing urgent requests.
• Collaborative Spirit: You thrive in cross-functional setups and understand how to manage diverse teams in an agile environment.
