Associate Director, Machine Learning (Core Algorithms)

At WHOOP, we're on a mission to unlock human performance and healthspan. WHOOP empowers members to perform at a higher level and live longer through a deeper understanding of their bodies and daily lives.We are seeking an Associate Director, Core Algorithms (Cloud) to lead the teams responsible for WHOOP's cloud-based algorithmic intelligence — the models and systems that transform physiological data into the sleep, recovery, and training insights our members rely on daily. This role is also responsible for ensuring our cloud algorithms evolve alongside WHOOP hardware, partnering with Sensor Intelligence and Hardware teams to translate new sensor capabilities into production-grade algorithmic experiences.You will own the technical vision, execution, and organizational health of this team. You'll drive the evolution of our core production algorithms such as workout detection, strain, and sleep staging toward higher accuracy, better member experiences, and more mature development practices. You will partner closely with ML Platform, Sensor Intelligence, Research, Product, and Software Engineering to define what WHOOP algorithms can enable — not just how they perform technically, but how they show up for members.This is a role for someone who has built and shipped physiological ML at scale in a consumer product, who has a deep product instinct for what algorithms mean to end users, and who knows how to elevate an ML organization's practices: raising the bar on tooling, processes, and standards to match the ambition of the work.RESPONSIBILITIESLead the cloud ML team responsible for the algorithms powering sleep, recovery, and trainingDirectly manage applied ML scientists and ML engineers; provide coaching, career development, and performance feedback that grows individual contributors into strong technical leadersEnsure the technical quality bar for algorithm development is maintained by establishing the processes, reviews, and standards that guarantee rigor from research through deployment, and diving into designs and architectural decisions where necessaryHelp drive the vision for what WHOOP algorithms and next-generation sensors can enable; advocate for member experience and push the boundaries of what our data makes possibleEnsure cloud algorithms remain compatible with future hardware generations; partner with Sensor Intelligence and Hardware to evolve proof-of-concept algorithms that leverage new sensor capabilities and bring them to production readinessEstablish and improve development lifecycle practices: experiment management, model validation, deployment pipelines, and production monitoringPartner with ML Platform / MLOps to define requirements and drive maturity improvements across experiment tracking, model monitoring, deployment automation, and observabilityDrive cross-functional alignment with Sensor Intelligence, Product, Software Engineering, and Research teamsQUALIFICATIONS8+ years of experience in machine learning or applied data science, with hands-on experience developing and shipping ML models for a consumer product4+ years of people leadership experience directly managing machine learning scientists/engineers, with demonstrated growth of team members and a track record of building high-performing teamsExperience scaling a production ML organization: growing teams and leaders, identifying gaps in the development lifecycle, and driving improvements that increase velocity, reliability, and rigorDeep product sense: ability to think about algorithms from the member's perspective, drive the vision for what algorithms can enable, and ensure the team is building toward meaningful user outcomesAbility to evaluate technical designs, guide architectural decisions, and ensure quality at the system level, without needing to write code day-to-dayExperience defining and driving cross-functional programs with engineering, product, and science partnersStrong communication skills with the ability to translate complex ML concepts to diverse audiences including product, engineering, and executive stakeholdersPREFERREDExperience building algorithms using physiological or wearable sensor data (e.g., PPG, accelerometer, temperature, bioimpedance)Experience managing through hardware-coupled development timelines where sensor availability and device generations constrain algorithm roadmapsFamiliarity with time-series modeling, sequential data, and the specific challenges of continuous physiological monitoringThis 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.
