Zusammenfassung

Hims & Hers is seeking a Sr. Director of Machine Learning to lead the teams building AI services at the core of our platform.

You will guide the applied side of our AI portfolio, including LLM-powered services for clinical intake, provider support, personalization, and operational workflows. You will set the technical direction for productionized AI, grow a team of ML engineers and ML production specialists, and ensure measurable, safe, and continuously improving outputs across clinical

Qualifikationen

• Led ML teams or cross-functional groups focused on AI systems.
• Experience building end-to-end ML services in production.
• Strong understanding of projection, eval, and safety for ML models.

Aufgaben

• Lead and grow ML engineers, applied scientists, and ML production engineers building AI services end to end - from problem framing through production operation.
• Own the strategy for how we build on top of frontier LLMs: prompt and context design, retrieval, tool and function calling, agentic workflows, structured output reliability, fallback and degradation behavior, latency and cost management.
• Drive the design of the harnesses and glue around LLM calls - orchestration, validation, guardrails, deterministic scaffolding - so probabilistic components produce dependable, auditable outputs inside product and clinical workflows.
• Direct development of in-house deep learning and classical ML models where a custom model outperforms a general-purpose one, including clinical and recommendation use cases such as medication and treatment-plan recommendations surfaced to providers.
• Set the bar for how AI services are productionized: SLOs for accuracy, latency and cost, graceful failure, rollout strategy, and clear ownership of production behavior.
• Make build-versus-fine-tune-versus-prompt decisions deliberately, and revisit them as model capabilities and pricing shift.

About the Role

We’re looking for a Sr. Director of Machine Learning to lead the teams building the AI services at the core of the Hims & Hers experience. This leader owns the applied side of our AI portfolio: the LLM-powered services that handle clinical intake, provider support, personalization, and operational workflows, as well as the in-house deep learning models that drive recommendations and predictions where accuracy and clinical soundness matter most.

This is a builder’s leadership role. You’ll set the technical direction for how we turn foundation models and custom models into dependable production services, grow a team of ML modelers and ML production engineers, and partner with our ML platform and evaluation organization to make sure what we ship is measurable, safe, and continuously improving.

You will:

Lead and grow ML engineers, applied scientists, and ML production engineers building AI services end to end - from problem framing through production operation.

Own the strategy for how we build on top of frontier LLMs: prompt and context design, retrieval, tool and function calling, agentic workflows, structured output reliability, fallback and degradation behavior, latency and cost management.

Drive the design of the harnesses and glue around LLM calls - orchestration, validation, guardrails, deterministic scaffolding - so probabilistic components produce dependable, auditable outputs inside product and clinical workflows.

Direct development of in-house deep learning and classical ML models where a custom model outperforms a general-purpose one, including clinical and recommendation use cases such as medication and treatment-plan recommendations surfaced to providers.

Set the bar for how AI services are productionized: SLOs for accuracy, latency and cost, graceful failure, rollout strategy, and clear ownership of production behavior.

Make build-versus-fine-tune-versus-prompt decisions deliberately, and revisit them as model capabilities and pricing shift.

Partner with Clinical and Medical Affairs to ensure clinically-facing models are developed with appropriate oversight, validation, and human-in-the-loop design; ensure providers stay in control of clinical decisions.

Partner closely with the ML infrastructure and evaluation team members to define evaluation criteria, feedback loops, and annotation needs for every service your team ships - and to hold your team accountable to the resulting metrics.
