Senior Client Account Director (SEO) in London

About Merj

Merj is a deeply technical SEO and AEO partner to global enterprise clients, engineering platforms, data and technology for meaningful performance. We shape resilient, discoverable platforms designed for good bots, search engines, and customers alike.

Engineered advantage: We find and implement hidden advantages that others miss to give our clients a clear edge.

Future-ready leadership: We actively experiment, test, and adapt to emerging search and AI technologies.

Strategic clarity: We make sense of complexity to define clear paths for growth.

The role

We're looking for a Senior Account Director to lead a portfolio of global enterprise clients. You will be the day-to-day point of contact for client relationships, the person responsible for keeping engagements healthy and growing, and the connective tissue between consulting, R&D, and growth. This is a hands-on role. You'll run accounts, shape roadmaps, offer strategic input, keep delivery on track, and make sure the work we ship reflects Merj's standards.

What you'll do

• Account management and retention
  • Manage relationships across a portfolio of enterprise accounts.
  • Hold the retention number for your portfolio.
  • Work closely with our SEO & AEO Director and Growth Director on new opportunities, renewals, commercials, and SOWs.
  • Work with our SEO & AEO Director, Ops Director and Growth Director to maintain and improve relationship scores across your portfolio.
  • Build account plans that reflect the client's commercial goals, not just our scope of work.
• Project and delivery management
  • Work alongside our lead consultants and project manager on day-to-day tasks, delivery, and quality management.
  • Keep scope, timeline, and quality in balance across every active workstream.
  • Set up the right rituals for each account including standups, working sessions, reporting cadences, async updates.
  • Spot risks early and resolve them before they become escalations.
  • Use Jira, Notion, and our internal SOPs to keep everything visible and accountable.
• Consulting and craft
  • Translate client business goals into plans of work.
  • Develop clear and actionable reverse briefs.
  • Work with our consultants to apply Merj's research and tooling to client problems.
  • Pressure-test recommendations before they reach the client.

What we're looking for

Must have

• Significant agency or consultancy experience leading global enterprise accounts.
• A track record of retaining and growing major clients over multi-year engagements.
• Experience working with clients in high-competition verticals such as retail, ecommerce, travel, financial services, fintech, and media.
• Strong project management instincts. You can run a complex program without losing the thread.
• Deep understanding of digital marketing across organic, paid, content, analytics, and lifecycle.
• Solid working knowledge of SEO. You don't need to be the most technical person in the room, but you need to hold your own with technical SEO and engineering teams.
• Exposure to AEO, LLM-driven search, or AI visibility work.
• Comfort working with senior client stakeholders, including legal, procurement, and C-suite.
• Clear written and verbal communication. You can write a sharp email, a clean status update, and a useful exec summary.
• Exposure to commercial models common in consultancy work, including retainers, fixed fee, and time and materials.

Nice to have

• Familiarity with tools such as Jira, Notion, GA4, GSC, or Profound.
• Experience leading international or multi-market programs across multiple regions and time zones.
• Experience with site migrations, replatforming, or working with headless and JS-heavy stacks.
• Experience working with US-based clients and stakeholders.
• A network in the SEO, digital, or marketing community, whether through speaking, writing, or community involvement.
• Project management qualifications such as PRINCE2 or Agile/Scrum certifications.

How you work

• You learn new frameworks and ways of working quickly, and you adapt rather than force-fit what worked before.
• You bring lessons from past roles into the work without making everything sound like the last place you were at.
• You're comfortable with ambiguity and you make decisions with incomplete information.
• You give and take feedback directly.
• You care about craft. You'd rather ship something good and slightly late than something average on time.

Attitude & Behaviours

• You thrive in a high-trust environment and bring:
• Ownership and accountability: You deliver on commitments and raise risks early.
• Precision: You define problems clearly, work from evidence, and communicate trade-offs.
• Curiosity and experimentation: You test ideas, run controlled experiments, and learn quickly.
• Collaborative delivery: You work well across disciplines and can lead working groups to get outcomes shipped.
• Clear communication: You write and speak with clarity, and can explain complex topics to non-specialists.
