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 around the world.

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

Posh enables anyone to build an IRL community based on shared interests, while connecting consumers with the communities of people just like them. Founded by event organizers who were frustrated with the growing loneliness epidemic and the tools available to build their own event brand, we’ve built the ultimate platform for launching, monetizing, and finding IRL communities of people just like you. In just 5 years, Posh has grown to a team of 65, expanded to 7M+ users, secured $70m in venture funding, and facilitated over $300M 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 role based in our New York City office in the heart of SoHo. Building live experiences and building with soul are important for our customers, and we believe being and working together as a team is the best way for Posh to feel and achieve this. Events on Posh should be fun, alive, and driven with passion and we want to mirror this in our teams every day!

What You'll Learn & Achieve
  • 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.

What We're Looking For:
  • 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.
