Senior Software Engineer, Growth

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 $31M in venture funding, and facilitated over $200M 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.

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 data. As a Senior Growth Engineer at Posh, you will be critical in driving user acquisition, engagement, and retention through innovative and data-driven strategies. As a Senior Growth Engineer, you will be the dedicated technical lead on our Growth Team, working alongside the Engineering team to spearhead experimentation and drive impact through fast-paced, innovative projects.

This is a hybrid 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.

• Develop and execute growth experiments and targeted initiatives across the Posh platform to enhance user acquisition, retention, and engagement.

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

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

• Integrate scalable tracking systems to ensure data integrity and actionable insights across all growth initiatives.

• Ability to extract actionable insights from data and translate them into impactful solutions.

• Conduct code reviews and contribute to knowledge-sharing initiatives within the Engineering Team, fostering a culture of growth and collaboration.

• 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.

• Strong understanding of growth strategies, experimentation frameworks, and metrics-driven decision-making.

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

• Experience with A/B testing frameworks or experimentation platforms (e.g., StatSig, LaunchDarkly).

• Strong knowledge of product metrics, funnels, and user lifecycle stages.

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

• A passion or curiosity for growth and improvement, coupled with the drive to explore innovative approaches that elevate user experiences and product success.
