Job Description

At WHOOP, we're on a mission to unlock human performance and healthspan. WHOOP empowers members to perform at a higher level and live longer through a deeper understanding of their bodies and daily lives. Protecting our members’ data and ensuring our systems scale securely and reliably is core to this mission.

WHOOP is hiring a Software Engineer II focused on backend development to build and enhance systems that power our platform. This role will directly contribute to delivering scalable and secure services that support millions of members worldwide. 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.

This is a top-funnel role: depending on your background and interests, you may align more closely with our Product Security team (focused on secure-by-default guardrails, compliance, and data privacy) or our Application Infrastructure team (focused on scalability, reliability, and developer enablement). Either way, you’ll have the opportunity to shape core platform practices and help WHOOP grow to the next level.

This posting is for an immediate new hire to our team. For those graduating in the fall of 2026 seeking entry level roles, we kindly ask that you check out this New Grad Opportunities job posting instead to be considered for roles opening at that time. Thank you.

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.

• Ensure system reliability, scalability, and performance through effective testing, monitoring, and optimization.

• Implement secure coding practices and contribute to designing systems that safeguard member data.

• Stay current with backend technologies and contribute to improving team engineering standards and best practices.

QUALIFICATIONS:

• 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.

BONUS QUALIFICATIONS:

• Experience working with infrastructure as code and developer enablement platforms.

• Familiarity with containers and orchestration (e.g., Docker, Kubernetes).

• Background in cloud security or incident response.

• Exposure to building translation or localization platforms to support multi-language content delivery.

• Hands-on experience with observability tools (logging, monitoring, alerting) in production environments.

ABOUT YOU

• 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.
