Job summary

Hims & Hers is seeking a senior ML leader to guide the design, development, and deployment of AI services across clinical and product workflows. You will own LLM strategy, build production-grade models, and drive measurable impact while partnering with clinical stakeholders and cross-functional teams.

You will oversee a team of ML engineers, scientists, and production engineers, shaping multi-year roadmaps, evaluating build-vs-fine-tune-vs-prompt decisions, and ensuring responsible AI practices.

Qualifications

• 14+ years of experience in machine learning and software engineering.
• 8+ years leading ML teams and managing managers or senior tech leads.
• Depth in modern LLM application development: RAG, prompt engineering, fine-tuning, evaluation, agent and tool-calling architectures.
• Comfort operating with ambiguity and shipping measurable impact.
• Excellent communication skills with executives and clinical stakeholders.
• Experience training and deploying deep learning models where outcomes matter.
• Bonus: healthcare, digital health, or safety-critical ML experience.
• Track record of shipping ML-powered products to production at scale and owning them operationally.

Responsibilities

• Lead and grow ML engineers, applied scientists, and ML production engineers.
• Own the strategy for building on frontier LLMs: prompts, retrieval, tools, and workflows.
• Design harnesses around LLM calls: orchestration, guardrails, and deterministic scaffolding.
• Develop in-house deep learning and classical ML models for clinical and recommendation use cases.
• Set production standards: SLOs for accuracy, latency, cost; governance and ownership.
• Decide when to build, fine-tune, or prompt, in response to evolving model capabilities and pricing.
• Partner with Clinical and Medical Affairs to ensure oversight and human-in-the-loop design.
• Collaborate with ML infrastructure to define evaluation criteria and accountability metrics.
• Translate ambiguous business problems into scoped, high-leverage ML work.
• Establish engineering and scientific standards across the team and mentorship practices.
