📍 Job Overview

Job Title: Principal Product Designer, Growth

Company: Weight Watchers

Location: United States - Remote

Job Type: Full-Time

Category: Product Design / Growth Operations

Date Posted: 2026-04-22

Experience Level: 10+ Years

Remote Status: Fully Remote

🚀 Role Summary

• Drive the end-to-end design vision and execution for critical growth funnels, including user acquisition, activation, retention, and monetization strategies.

• Lead 0→1 growth initiatives, defining foundational systems and shaping initial iterations of new conversion and monetization experiences within a complex, ambiguous environment.

• Act as a strategic partner to product, engineering, data science, and marketing teams, influencing product strategy and experimentation roadmaps through data-informed insights and exceptional design craft.

• Mentor and elevate the design practice by establishing experimentation frameworks, standards, and fostering a culture of continuous learning and high-quality execution.

📝 Enhancement Note: While the title is "Principal Product Designer, Growth," the responsibilities heavily emphasize driving business metrics through design, aligning with a "Growth Operations" or "Product Growth" function. This role requires a deep understanding of user funnels, A/B testing, and data-driven decision-making, which are core to operations. The emphasis on "0→1 growth initiatives" and "shaping first iterations" suggests a need for strategic thinking and the ability to define new processes and systems from scratch, a key aspect of operations.

📈 Primary Responsibilities

• Design Leadership & Strategy:

  • Lead and drive the design vision for major growth surfaces (Acquisition, Activation, Retention), influencing product strategy and experimentation roadmaps in close collaboration with Product and Engineering leadership.
  • Spearhead early-stage, ambiguous problem spaces by framing opportunities, defining foundational systems, and shaping first iterations of new conversion and monetization experiences.
  • Serve as a trusted strategic partner to executive stakeholders, advocating for best product practices and ensuring alignment with long-term business objectives.

• Craft & Execution:

  • Translate complex business requirements, user friction points, and funnel data into clear strategy and intuitive, elegant user experiences.
  • Deliver high-quality interaction designs, prototypes, and visual systems for growth-focused product areas.
  • Lead rapid experimentation and utilize advanced prototyping tools to bring concepts to life, iterating and validating solutions through A/B testing, quantitative data, and user feedback.

• Collaboration & Practice Building:

  • Partner effectively across Engineering, Product, Data Science, and Marketing teams to ensure design decisions are technically feasible, measurably impactful, and strategically aligned.
  • Collaborate with Design and Product leadership to establish experimentation frameworks, standards, and documentation that mature the growth design practice.
  • Articulate design decisions and narratives clearly to stakeholders at all levels, creating alignment and driving accountability through the lens of business impact.

• Mentorship & Culture:

  • Mentor and coach designers across all levels, providing guidance on product strategy, craft excellence, and professional growth within the design organization.

  • Model exceptional design practice and foster a culture of continuous learning, curiosity, and high-quality execution within the team.

📝 Enhancement Note: The responsibilities highlight a blend of strategic leadership, hands-on execution, and practice-building, which is common for senior roles in growth-focused product teams. The emphasis on "0→1 growth initiatives," "shaping first iterations," and "experimentation frameworks" points towards a need for operationalizing design processes for growth, rather than just executing on defined projects. This requires a systematic approach to problem-solving and continuous improvement, core to operations.
