About POSH

Humans are fundamentally social creatures, but the largest "social" companies today have evolved into purely digital content providers, exacerbating the isolation, loneliness, and mental health challenges plaguing our society. POSH enables anyone to become event organizers and build community around their followings, bringing people together in-person to cultivate real-world human connection. Founded by event enthusiasts and college dropouts, we've built the ultimate set of tools for creating, marketing, and selling tickets to live experiences.

In just three years, POSH has grown to a team of 30+, expanded our user base to 2M+, secured $31M in venture funding, and facilitated over $100M in transactions.

About The Role

At POSH, you'll help shape our platform that brings people together through live events. Your work will directly impact how event organizers create experiences and how attendees discover and enjoy them.

We're looking for someone who excels in both technical skills and leadership. You'll tackle exciting projects that push our platform forward. Some recent work includes building a system for users to follow each other, creating curated event playlists, and tools for affiliate event promotion. If you enjoy solving real-world problems and working in a fast-paced environment, you'll fit right in.

This is an in-person position at our New York City office located in the heart of SoHo, where you'll be part of a team that's revolutionizing how people connect in the real world.

Key Responsibilities:

Lead the architecture design and implementation of complex features.

Demonstrate full stack experience with specialization in either frontend, backend, or infrastructure while contributing to broader projects.

Collaborate on architecture and technical decisions that influence the direction of the platform, ensuring scalability, performance, and user-focused improvements.

Focus on performance optimization and system reliability, especially as our user base grows.

Build with data and analytics in mind which provides actionable insights for business leaders and event organizers.

Drive experimentation with MVPs, balancing rapid iteration with long-term sustainable growth and developer experience.

Contribute to either frontend design systems, database design, or dev ops/infrastructure to ensure scalable, secure, and maintainable systems.

Provide mentorship to engineers, fostering a culture of growth and collaboration.

Ideal Candidate:

5+ years of experience leading complex technical projects with significant business impact.

Strong expertise in a specific area (e.g., frontend, backend, or infrastructure) while maintaining broad knowledge of the full stack.

Proficiency in relevant technologies (e.g., React, React Native, Typescript, AWS or similar cloud providers), with experience in either mobile app development or backend systems.

Experience with scalability, performance optimization, and building tools that support data-driven decision-making.

Strong problem-solving skills and a passion for creating products that connect people in the real world.

Ability to lead initiatives, mentor others, and communicate effectively across technical and non-technical teams.

Experience working at consumer, social, or marketplace companies is a plus, as it speaks to our user-centric values at POSH.

When applying, please include links to your GitHub profile or a portfolio of past projects.
