Job description

At WHOOP, our mission is to unlock human performance and healthspan. Our enterprise platform helps organizations across athletics, business, healthcare, and public service better understand and support the health and performance of their teams.
WHOOP Enterprise is entering a new phase of growth and reinvestment. We're looking for a Software Engineer II to play a critical role in evolving the Enterprise platform; building core systems, shaping technical direction, and laying the foundation for a scalable enterprise product.
This is a high-ownership role with meaningful autonomy. You'll operate in a product-ambiguous environment, help define what "great" looks like, and partner closely with design, stakeholders, and leadership as the platform takes its next step forward.
RESPONSIBILITIES:
  • Own and evolve foundational systems for WHOOP Enterprise, starting with Enterprise APIs, authentication, and account management
  • Design, build, and maintain backend services and APIs that support enterprise use cases and external integrations
  • Collaborate closely with design, analytics, and engineering partners to translate ambiguous product needs into scalable technical solutions
  • Define and influence technical direction, system architecture, and implementation standards for the Enterprise platform
  • Build systems with a strong emphasis on security, privacy, reliability, and correctness, appropriate for enterprise customers
  • Develop and maintain observability, monitoring, and operational practices to ensure system stability
  • Consistently deliver high-quality, well-tested code following best practices in software design and development
  • Help establish engineering foundations that scale, including documentation, patterns, and mentorship as the team grows

QUALIFICATIONS:
  • 2+ years of professional software engineering experience, with a strong foundation in backend development
  • Experience building and owning production backend systems and RESTful APIs (Java preferred)
  • Familiarity with authentication, authorization, and identity or account management concepts
  • Experience working with relational databases such as PostgreSQL
  • Experience designing and operating services in cloud environments (AWS)
  • Comfort working across the stack, including contributing to web applications leveraging AI tools (e.g., React), even if backend is your primary strength
  • Strong system design skills, with experience building scalable, reliable, and maintainable software
  • Ability to operate effectively in fast-paced, high-ambiguity environments with minimal product process
  • Strong independent problem-solving skills and a sense of ownership over outcomes
  • Clear communicator who collaborates well across disciplines and can articulate technical tradeoffs
  • Builder mindset with interest in helping shape and scale a platform and team over time

Learn more about our Software Org and how to be successful in your engineering career at WHOOP via our Career Framework.
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. As we continue to build a diverse and inclusive environment, we encourage anyone who is interested in this role to apply.
WHOOP is an Equal Opportunity Employer and participates in E-verify to determine employment eligibility. It is unlawful in Massachusetts to require or administer a lie detector test as a condition of employment or continued employment. An employer who violates this law shall be subject to criminal penalties and civil liability.
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 $125,000 - $215,000. 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.
