Job description

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.

WHOOP is seeking a Senior Reliability Engineer to lead the charge in ensuring our hardware products deliver a consistent, high-reliability experience for members. In this critical role, you will influence the full product lifecycle, from early design through mass production. Applying deep technical expertise to data-driven, risk-informed decisions and ensuring reliability is embedded in every phase of development. Your work will directly support WHOOP's ability to innovate quickly while maintaining industry-leading quality and performance standards.

RESPONSIBILITIES:
  • Own and drive reliability strategy across New Product Introduction (NPI), in-market monitoring (ORT/ Field Reliability), and continuous improvement initiatives, ensuring alignment with program risk and launch readiness

  • Define reliability requirements, targets, and validation strategies (e.g., DVT success criteria, AFR targets), ensuring products meet predictable launch outcomes and achieve reliability within defined thresholds

  • Identify, assess, and mitigate reliability risks early through structured methodologies (DFMEA, HALT, accelerated testing), achieving high coverage of critical failure modes prior to launch

  • Translate use cases and field conditions into system-level test strategy and execution plans (Test Protocols), ensuring no major unknown failure modes escape into market

  • Analyze reliability data to generate actionable insights (AFR, CoUR, TWR), influencing cross-functional decisions across design, manufacturing, and supply chain

  • Lead root cause investigations and corrective actions for test and field failures, driving resolution of top issues and enabling sustained product performance without regression

  • Partner with internal teams and external suppliers to standardize reliability practices, scale test capabilities, and ensure consistent execution across global partners

  • QUALIFICATIONS:
  • 8+ years of experience successfully applying Design for Reliability (DfR) principles, preferably in high-volume consumer electronics or wearable/medical device environments

  • Bachelor's or Master’s degree in Mechanical Engineering, Materials Science, Reliability Engineering, or a related field

  • Strong understanding of reliability principles across electro-mechanical systems, including failure mechanisms in materials, components, and assemblies

  • Experience defining and executing reliability test strategies (HALT, HASS, ALT) and translating results into product and business decisions

  • Proficiency in statistical analysis, reliability modeling, and structured problem-solving methodologies for root cause identification

  • Demonstrated ability to influence cross-functional teams and drive alignment on risk-based decisions in fast-paced development environments

  • Experience working with global suppliers and manufacturing partners to improve product reliability and test consistency

  • Strong communication skills with the ability to clearly convey complex technical insights to diverse audiences

  • Strong commitment to embracing and leveraging AI tools in day-to-day tasks, ensuring AI-assisted work aligns with the same high-quality standards as personal contributions

  • ASQ Certified Reliability Engineer (CRE) certification preferred
