Head of Engineering

About this role

About Evvy At Evvy, we believe the female body shouldn’t be a medical mystery. We are a precision women’s health company leveraging the vaginal microbiome to improve outcomes across a woman's lifespan. Backed by $30M+ from leading investors, we serve over 100,000 patients and 2,000 providers nationwide with our validated Vaginal Microbiome Test and AI-powered personalized care platform.

Why join now? Evvy is a generational opportunity in women's health — and we're at the inflection point. We’ve built a dataset no one has. Evvy has generated the world’s largest vaginal microbiome dataset from 100,000+ patients, uncovering novel biological markers underlying women’s health conditions that collectively cost the healthcare system $180B+ annually. Validated, AI-first platform. We’ve built a comprehensive testing and care platform that unlocks personalized treatment pathways for each patient. Our work is supported by research published in major peer-reviewed journals and presented at major clinical conferences (including ACOG, ASRM, IDSOG, and more). Proven traction, massive opportunity. We serve 100,000+ patients and 2,000 providers nationwide, with rapidly growing revenue and an expanding suite of diagnostics and treatments to improve outcomes across condition areas. We've only scratched the surface. Top tier team, investors, and partners. Our world-class team is backed by industry leading investors, including General Catalyst, Left Lane Capital, US Fertility, and Labcorp. We're looking for high-horsepower, mission-driven people who find it unacceptable that the female body is still a medical mystery — and want to help change that. The Role We’re looking for a Head of Engineering to help build the technical foundation for the future of women’s healthcare. At Evvy, engineering sits at the center of everything we do — from diagnostics and patient experiences to AI-powered personalization, clinical operations, and data infrastructure. This role is about using modern engineering and AI-native development to dramatically increase the speed, leverage, and ambition of what a small team can accomplish. As Head of Engineering, you’ll report directly to the CEO and lead Evvy’s technical vision, architecture, and execution as we scale. You’ll oversee the evolution of our platform across patient experiences, internal tooling, AI-powered workflows, clinical infrastructure, and data systems — helping ensure we move quickly without compromising quality, reliability, or trust. We’re looking for someone deeply hands-on and intensely product-minded. You should be excited about working directly in the weeds with the team: reviewing architecture decisions, unblocking engineers, experimenting with new tooling, prototyping systems, and helping the organization adopt the newest AI-enabled development workflows. You should have strong instincts for how modern engineering organizations operate in an AI-native world — where lean, highly-leveraged teams can execute roadmaps that previously required significantly larger organizations. Evvy is a primarily in-person team based in NYC. Given the cross-functional nature of this role, our ideal candidate is located in NYC.
