The job
Flo Health is the world’s most popular women’s health app, supporting over 80 million monthly active users. 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; we build the systems that make it possible at scale. 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 Environment
Our 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.
What You’ll Do
- Lead & Empower: Manage a team of senior engineers using a distributed leadership model. You’ll provide the management layer that supports their technical execution, performance, and career growth.
- Own the Roadmap: Translate product and company goals into clear team roadmaps, managing the balance between structured delivery and the reactive, business-driven work essential to a platform team.
- Drive Delivery: Coordinate cross-pod dependencies, resolve blockers, and track roadmap milestones.
- Technical Stewardship: Participate in architectural reviews and provide hands-on technical guidance (~20% of your time). 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.
What you bring:
- 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.
Why Join Flo?
- Massive Scale: Your work will directly impact millions of users.
- Cutting-Edge Tech: Work at the intersection of AI and healthcare, with deep integration into modern LLM stacks and ML infrastructure.
- High Visibility: This role offers significant industry exposure, including potential opportunities to present our evaluation platforms at events alongside our technology partners.
