About WHOOP

You thrive on ownership and want to shape the foundation of WHOOP’s platform

Responsibilities

  • Design, develop, and maintain robust, scalable backend systems that power WHOOP’s core infrastructure and member experience.
  • Collaborate with product managers, data engineers, frontend developers, and other cross-functional partners to deliver features that enhance member engagement.
  • Build and maintain APIs to enable seamless integration with frontend applications and third-party services.
  • You believe reliability, security, and visibility are just as important as speed and scale

Requirements

  • Familiarity with cybersecurity principles (data privacy, authentication, and authorization) is a plus but not required
  • Strong problem-solving skills and ability to work in a fast-paced environment
  • Familiarity with database design and management (e.g., PostgreSQL, MySQL, or NoSQL databases)
  • Exposure to event-driven architecture (messaging/streaming tech such as Kafka, RabbitMQ)

Understanding of cloud infrastructure (AWS, GCP, or Azure)

  • Good communication skills and ability to collaborate across teams
  • 2-4 years of backend software development experience, ideally in languages like Java, Python, or C#

Experience designing and building RESTful APIs and microservices

  • You automate everything you can, always seeking to replace manual work with scalable tooling
  • You enjoy working cross-functionally and can communicate complex infrastructure and security topics clearly

Background in cloud security or incident response

  • Familiarity with containers and orchestration (e.g., Docker, Kubernetes)
  • Hands-on experience with observability tools (logging, monitoring, alerting) in production environments
  • Experience working with infrastructure as code and developer enablement platforms

Preferred

  • While backend development expertise is the primary focus, familiarity with cybersecurity concepts (data privacy, AuthN/AuthZ, etc) or cloud infrastructure concepts (AWS, IaC, Kubernetes, etc) will be considered a strong plus
  • Exposure to building translation or localization platforms to support multi-language content delivery
