Sr. SEO Specialist

Wonderist Agency - Dental Marketing•San Diego, CA

About The Position

The Senior SEO Specialist will be responsible for managing and optimizing a portfolio of client accounts in a fast-paced, high-growth agency environment. This role requires an individual who is highly organized, strategic, and capable of executing SEO initiatives across a portfolio of websites at scale. The primary focus is on driving quality organic search performance, improving rankings, and increasing website visibility for our clients in the dental industry. As a senior member of the SEO team, you’ll go beyond day-to-day implementation—taking ownership of complex client scenarios, advising on strategy, and helping ensure delivery at scale in a fast-moving startup environment. You’ll be expected to support junior team members, delegate where appropriate, and contribute to elevating both the quality and efficiency of execution across the department. This role also includes owning portions of vendor relationships, working cross-functionally with third-party partners to ensure alignment, quality, and smooth delivery. You’ll collaborate with the SEO Team Lead to identify areas for process improvement and play an active role in scaling systems that support growth across hundreds of clients. The Senior SEO Specialist combines technical SEO, content strategy, local optimization, and off-page SEO to create tailored, results-driven strategies. Unlike in-house SEO roles, which focus on a single brand, this position requires the ability to prioritize a large, diverse portfolio, troubleshoot performance challenges, and stay agile as industry trends evolve. The ideal candidate thrives in an agency setting, has strong communication skills, and can confidently translate SEO insights into actionable client recommendations. You should be comfortable navigating ambiguity, taking initiative, and working collaboratively across web, content, paid media, and external partners to deliver cohesive, measurable outcomes.
