To thrive as a Backend Engineer Java, you need a solid understanding of Java programming, data structures, algorithms, and experience with backend frameworks, typically supported by a relevant degree or industry experience. Familiarity with tools and technologies such as Spring Boot, RESTful APIs, relational databases, and build systems like Maven or Gradle is commonly required. Problem-solving ability, teamwork, and effective communication are crucial soft skills for excelling in collaborative and fast-paced development environments. These combined skills ensure robust, scalable backend systems that meet business needs and integrate smoothly within larger software architectures.

How does a backend engineer Java typically collaborate with frontend developers and other stakeholders in a project?

As a Backend Engineer Java, you will regularly collaborate with frontend developers to ensure seamless integration between server-side logic and user interfaces.

You’ll also engage with product managers, QA engineers, and sometimes DevOps teams to align on project goals, timelines, and deployment strategies. Effective communication is key to translating business requirements into reliable backend solutions and maintaining smooth workflows across the team.

At WHOOP, we're on a mission to unlock human performance and healthspan. WHOOP empowers members to perform at a higher level through a deeper understanding of their bodies and daily lives. Our wearable technology monitors vital physiological metrics to provide personalized insights that improve fitness, health, and recovery.
As a Software Engineer I, you will contribute to the design, development, and maintenance of the services that power WHOOP's core product experiences. 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. 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.
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:
  • Contribute to the development and maintenance of backend services and APIs that power WHOOP's member-facing features using technologies such as Java, Kafka, Postgres, and AWS.
  • 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.

QUALIFICATIONS:
  • 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.

This role is based in the WHOOP office located in Boston, MA. The successful candidate must be prepared to relocate if necessary to work out of the Boston, MA office.
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.

The WHOOP compensation philosophy is designed to attract, motivate, and retain exceptional talent by offering competitive base salaries, meaningful equity, and consistent pay practices that reflect our mission and core values.
At WHOOP, we view total compensation as the combination of base salary, equity, and benefits, with equity serving as a key differentiator that aligns our employees with the long-term success of the company and allows every member of our corporate team to own part of WHOOP and share in the company's long-term growth and success.
The U.S. base salary range for this full-time position is $105,000 - 145,000. Salary ranges are determined by role, level, and location. Within each range, individual pay is based on factors such as job-related skills, experience, performance, and relevant education or training.
In addition to the base salary, the successful candidate will also receive benefits and a generous equity package.
These ranges may be modified in the future to reflect evolving market conditions and organizational needs. While most offers will typically fall toward the starting point of the range, total compensation will depend on the candidate's specific qualifications, expertise, and alignment with the role's requirements.
