Senior Client Strategist

About this role

At Wellist, we’re helping employers deliver the right resources at the right time—so employees can feel supported through every life moment, and HR leaders can maximize the value of their investments.

As our Senior Client Strategist you’ll serve as a trusted strategic advisor to enterprise employers as they launch Wellist. Rather than simply executing implementation plans, you’ll partner with HR and Benefits leaders to solve complex organizational challenges, design tailored employee experience strategies, and guide clients through meaningful change that drives platform engagement and measurable business outcomes.

We’re looking for a structured problem solver who thrives in ambiguity, communicates with executive presence, and enjoys building scalable frameworks from the ground up. If you’re energized by partnering with enterprise customers, influencing senior stakeholders, and helping build a world-class implementation function within a high-growth company, this role is for you.

What You’ll Own

End-to-End Implementation Leadership

• Serve as the primary strategic lead for new enterprise client engagements, owning the relationship and implementation from kickoff through launch and early optimization.

• Build tailored implementation plans that align with each employer’s workforce needs, benefits portfolio, and engagement goals.

• Partner closely with internal stakeholders (Support, Product, Directory, and Activation) to translate client needs into coordinated, cross-functional solutions.

• Track project milestones and dependencies, manage risks, and keep timelines on track with precision.

Client Strategy & Customization

• Design the overall client experience, implementation strategy, activation approach, communication plan, and directory customization strategy to reflect each employer’s culture, workforce, and priorities.

• Lead discovery conversations to understand workforce challenges and translate those into actionable solutions.

• Collaborate with client stakeholders to develop launch campaigns, email communications, and internal engagement strategies.

Program Activation & Optimization

• Implement and refine strategic activation plans—including segmented outreach, referral prompts, and tailored content—to drive employee engagement, adoption, and measurable client outcomes.

• Analyze client performance data and user feedback to identify early wins and opportunities for improvement.

• Serve as a strategic advisor to HR and Benefits leaders—ensuring that each program delivers value and exceeds expectations.

Scalable Systems & Process Excellence

• Codify implementation workflows, toolkits, and playbooks to support future scale.

• Define and track key success metrics (e.g., time to launch, adoption rates, satisfaction scores).

• Help shape Wellist’s enterprise implementation methodology and play a key role in building a scalable, consultative client success function.
