About POSH

We are all social creatures, but the dominant “social” companies today have evolved into digital loneliness machines, driving isolation, anxiety, and mental health challenges across our lives.

Human connection is lost. Posh is a beacon guiding us back.

Posh enables anyone to become an event organizer, build a community around their followers, and bring people together in person to cultivate real-world human connections. Founded by event enthusiasts and college dropouts, we’ve built the ultimate tools for creating, marketing, and monetizing in-person communities globally. In just three years, Posh has grown to a team of 60, expanded to 5M+ users, secured $40m in venture funding, and facilitated over $220M in transactions. We've achieved more than teams ten times our size in a tenth of the time—and there's so much more to come.

• Promote org-wide knowledge sharing, code quality, and technical excellence.

• Partner with leadership to align technical initiatives with product vision and business goals.

• Lead innovation in architecture, infrastructure, and product systems, ensuring adaptability as POSH scales.

• Balance rapid experimentation with sustainable design, driving forward both business growth and developer productivity.

Ideal Candidate:

• 10+ years of experience leading complex, large-scale technical projects with broad organizational impact.

• Proven track record shaping technical strategy and making architectural decisions that balance scalability, sustainability, and business goals.

• Experience mentoring and developing senior engineers, creating structures for org-wide growth and knowledge sharing.
