Role
Who you are
- This is a growth-oriented role ideal for engineers who are excited to learn, ship high-quality code, and make an impact in a fast-paced, mission-driven environment
- Professional experience in backend software development (internship, co-op, or academic project experience acceptable)
- Experience building or interacting with RESTful APIs and relational databases (e.g., Postgres or similar SQL-based systems)
- Proficiency in an object-oriented programming language such as Java, or demonstrated ability to quickly learn new backend technologies
- Familiarity with version control systems such as Git and standard development workflows
- Understanding of fundamental computer science concepts including data structures, algorithms, and system design basics
- Interest in distributed systems, event-driven architectures (e.g., Kafka or similar technologies), and cloud platforms such as AWS
- Strong problem-solving skills and a growth mindset, with a willingness to seek feedback and continuously improve
- Effective communication skills and the ability to collaborate within a cross-functional team environment
- Interested in the role, but don’t meet every qualification? We encourage you to still apply! At WHOOP, we believe there is much more to a candidate than what is written on paper, and we value character as much as experience

You will work closely with experienced engineers, product managers, designers, and data scientists to build scalable, reliable systems that deliver meaningful insights to our members

- Collaborate with cross-functional partners across Product, Design, Data Science, and Engineering to translate requirements into well-scoped technical solutions
- Write clean, maintainable, and well-tested code while participating in code reviews to continuously improve engineering quality and standards
- Support the operation and monitoring of production systems, helping to troubleshoot issues and ensure reliability, scalability, and performance
- Break down feature requirements into actionable tasks, identify risks early, and iterate quickly to deliver value to members
- Contribute to technical documentation and knowledge sharing to support team velocity and long-term maintainability
Our take
WHOOP develops wearable health-tracking devices designed to help athletes optimise their performance. Its technology continuously monitors recovery, sleep, and training hours to fine-tune both individual and team performance. Unlike competitors that primarily track exercise data, WHOOP's holistic approach includes metrics like heart rate variability, which can influence more effective and healthier exercise routines.
By focusing on a subscription model that includes the cost of the physical device, WHOOP differentiates itself from competitors that charge a higher one-time fee for their products. This model provides ongoing value and encourages users to stay engaged with their health data.
WHOOP's comprehensive monitoring of strain and recovery has given it a competitive edge, even as other brands like Fitbit have incorporated similar features. Beyond sports performance, WHOOP has conducted extensive research on predicting premature births, aiming to integrate these findings into its app. This commitment to broader health applications demonstrates WHOOP's dedication to advancing wearable health technology.
