Description

Company Description WD is building the infrastructure behind the AI-driven data economy. As AI scales, so does data. Every interaction, every model, every system generates data that must be stored, managed, and made accessible over time. That’s where we come in. We combine deep engineering expertise with global-scale manufacturing to deliver the storage systems that make AI possible, powering hyperscale data centers, cloud platforms, and enterprise infrastructure worldwide. This isn’t theoretical work. It’s real systems, at real scale, people solving some of the hardest challenges in technology today. We’re looking for people who want to build, solve, and operate at that level. Join us and let’s shape the future of data. Job Description Key Responsibilities Technical Leadership & Program Ownership Lead the end-to-end design, architecture, and implementation of large-scale machine learning programs involving multiple interconnected projects Own the technical vision and roadmap for ML initiatives across the organization, ensuring alignment with business objectives Drive solutioning efforts for complex, ambiguous problems by breaking them down into actionable technical components Establish best practices, design patterns, and architectural standards for ML systems at scale Make critical technical decisions on model selection, infrastructure, tooling, and deployment strategies Champion production excellence by ensuring ML systems are reliable, scalable, maintainable, and cost-efficient Goals & Metrics Ownership Define success metrics and KPIs for ML initiatives, establishing clear linkage between technical work and business outcomes Drive a metrics-driven culture by implementing comprehensive monitoring, experimentation frameworks, and impact measurement systems Analyze and communicate the business impact of ML solutions through rigorous A/B testing and causal inference methodologies Set and track ambitious yet achievable goals for your programs, proactively identifying and mitigating risks Translate business objectives into quantifiable ML objectives and success criteria Mentorship & Team Development Mentor and guide junior and mid-level data scientists and ML engineers, accelerating their technical growth and career development Conduct code reviews, design reviews, and provide constructive feedback to elevate team quality standards Foster a culture of technical excellence, innovation, and continuous learning within the team Develop and deliver technical training sessions on
