Euphoric builds AI-first employee benefits administration software for the world’s largest and most prestigious employers. Born
out of Peppy Health — a fast-growing, category-defining Series B startup — we spun out in May 2025 to tackle a far bigger
opportunity.
Global employers spend $3–5 trillion on benefits every year. It’s their second-largest cost after payroll — yet the entire
category is still running on legacy systems and outdated assumptions. The space is primed for transformation: despite its scale,
it’s been almost completely overlooked by AI-first startups. Incumbents — including one U.S. heavyweight with $2B+ in annual
revenue — are constrained by archaic tech stacks and can’t move fast enough to innovate.
And this isn’t just a massive market — it’s genuine “tech for good.” Smarter benefits administration, richer analytics, and
clearer communication have the power to directly improve the everyday lives, wellbeing, and financial security of millions of
employees worldwide.
We’re a sharp, high-velocity team with bold ambitions, obsessed with building category-defining technology and partnering with
exceptional people who want their work to truly matter.
We closed significant seed rounds in October 2025 & May 2026 and are building from a position of strength with a long cash runway.
We've already secured contracts with several of the world's largest enterprises and are now preparing for rapid expansion as we
scale the platform globally.
We’re looking for a Software Engineer to bring their ambition, creativity, and technical prowess to join our high-powered team to
build the technology that powers the world’s first lovable, AI-native benefits platform.
You’ll have real ownership, big targets, and a chance to help shape both the work you do and the company in general. We care less
about traditional career paths and more about raw talent, bias for action, and how much fire you bring.
platform features that leverage personalization, experimentation, and AI/ML methods (e.g. agents/LLMs, recommender systems,
reinforcement learning) to enhance user experience in a meaningful business domain.
on the backend, shipping production-ready code and user-facing features in addition to innovative ML work.
development tools (Cursor, Windsurf), keep up with the regular drumbeat of AI advances, and find new and exciting ways to build
and explore new features faster.
