About this role

Hims And Hers is hiring for a Principal Engineer, Applied AI (Fullstack/Backend) role (full-time). See the official posting for full details.

Requirements

  • 15+ years of professional software engineering experience with deep architectural expertise and a record of delivering production systems at scale.
  • Proven track record of influencing technical strategy and delivering cross-org technical initiatives at the group or organizational level.
  • Excellent track record standing up services at scale in production, with a demonstrated ability to think about robustness, scalability, and debuggability from day one.
  • Deep experience owning service architecture across a full stack — understanding how services should blend together, not just how to build any one of them well.
  • A "productionization" mindset: comfortable being the counterweight to a fast-moving research/experimentation culture, focused on uptime and reliability.
  • Hands-on engineering ability; you want to stay close to the code and the architecture, not just the roadmap.
  • Some exposure to LLM/AI services — you don't need deep AI expertise, but you should have tested the waters with LLM or AI-powered systems in some capacity.
  • Ability to think long-term and build for the future, balancing near-term delivery with durable architecture.
