Senior SEO Strategist

Overview

We’re looking for a hands-on SEO expert to serve as our in-house authority on all things SEO. You’ll guide strategy and decision-making across the team, mentor colleagues on best practices, and execute SEO work directly for client accounts. You’ll partner closely with the Director of SEO, who leads client relationships and project delivery — you bring the technical/strategic SEO depth.

Key Responsibilities

• Serve as the internal SEO subject-matter expert — advise team members and leadership on strategy, best practices, and decisions
• Educate and upskill a small team (1-5 people) on SEO fundamentals and advanced tactics
• Execute hands-on SEO work: audits, keyword research, technical fixes, content optimization, link strategy, reporting
• Support client-facing conversations when SEO expertise is needed (calls, strategy presentations, Q&A)
• Leverage AI tools to scale SEO workflows — research, content briefs, audits, reporting — and help the team adopt them effectively
• Stay current on algorithm updates, industry trends, and tooling; translate changes into actionable guidance
• Diagnose and troubleshoot SEO performance issues across client accounts
• Adapt quickly as algorithms, client priorities, and industry best practices shift — this role requires comfort with ambiguity and frequent change

Requirements

• 4-7 years hands-on SEO experience (technical, content, and off-page)
• Proven track record improving organic search performance
• Genuine enthusiasm for using AI tools to work smarter and scale output
• Comfortable explaining SEO concepts to non-experts (leadership, clients, junior team members)
• Experience with SEO tools
• Strong written/verbal communication — will present findings to clients and team
• Adaptable to shifting priorities, algorithm changes, or client needs without missing a beat
• Comfortable working remote/async

Nice to Have

• Agency experience
• Experience mentoring or training others informally
• Experience building or refining AI-assisted SEO workflows
