Backend Software Engineer, WHOOP

• 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
• 2-4 years of backend software development experience, ideally in languages like Java, Python, or C#
• Experience designing and building RESTful APIs and microservices
• Exposure to event-driven architecture (messaging/streaming tech such as Kafka, RabbitMQ)
• Familiarity with database design and management (e.g., PostgreSQL, MySQL, or NoSQL databases)
• Understanding of cloud infrastructure (AWS, GCP, or Azure)
• 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
• Good communication skills and ability to collaborate across teams
• You thrive on ownership and want to shape the foundation of WHOOP’s platform
• 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
• You believe reliability, security, and visibility are just as important as speed and scale
