RESPONSIBILITIES:

  • Help execute WHOOP's vision to build and scale the use of Generative across our Core product
  • Develop backend features and services, leveraging Java, AWS, and PostgreSQL to deliver scalable and reliable software solutions.
  • Collaborate with cross-functional teams—including Product, Design, and Data Science—to gather technical requirements and deliver impactful infrastructure and tools
  • Design abstraction layers that empowers Product and Software teams to leverage Generative AI in the WHOOP product.
  • Consistently deliver high-quality code, adhering to best practices in software design and development.
  • Develop and maintain observability and monitoring systems to ensure the stability and reliability of deployed features.
  • Mentor and support junior engineers, fostering a culture of collaboration and continuous improvement.

QUALIFICATIONS:

  • Experience in backend development, working on large-scale software systems.
  • Experience building applications on top of Large Language Models.
  • Expertise in API design and development (preferably with Java).
  • Experience in relational database design and development (SQL).
  • Experience with scalable system design and performance optimization.
  • Strong independent problem-solving skills and the ability to work effectively in a fast-paced, collaborative environment.
  • Excellent communication skills and a commitment to delivering high-quality work.
