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.

What You’ll Do
  • Design and evolve infrastructure: Architect resilient, scalable, and secure infrastructure using cloud-native tools (AWS preferred).

  • Automate everything: Develop CI/CD pipelines and infrastructure-as-code systems (e.g., Terraform, GitHub Actions, Docker) to make deployment seamless and consistent.

  • Monitor and improve reliability: Implement alerting, logging, and tracing systems that empower teams to diagnose and resolve issues quickly.

  • Collaborate cross-functionally: Partner with engineers across backend, frontend, and data to optimize how services are built, tested, and deployed.

  • Harden cloud security: Contribute to IAM design, least-privilege access, and posture management across environments.

  • Drive operational excellence: Identify bottlenecks and reliability risks, and build solutions that scale with Posh’s growth.

  • Mentor and elevate: Coach engineers on best practices for infrastructure design, cloud efficiency, and secure deployment.

What You Bring
  • 5+ years of experience as an Infrastructure, DevOps, or Backend Engineer.

  • Deep knowledge of AWS services (EC2, Lambda, CloudWatch, IAM, SNS/SQS, etc.) and infrastructure automation (Terraform, CloudFormation).

  • Experience with CI/CD pipelines, containerization (Docker), and orchestration systems (ECS, EKS, or equivalent).

  • Proficiency in Java, JavaScript, or Python, and familiarity with scripting for automation.

  • Strong grasp of cloud security principles, identity and access management, and cost optimization.

  • Solid understanding of networking fundamentals, observability, and system reliability.

  • Excellent communication and collaboration skills; able to partner with diverse engineering teams.

  • A passion for automation, scalability, and improving developer velocity.

Nice to Have
  • Experience with multi-region or distributed cloud systems.

  • Exposure to compliance and security tooling for cloud posture management.

  • Contributions to open-source infrastructure tools.

  • Background in mentoring engineers or leading reliability initiatives.
