SEO Lead London

Harnham’s London office receives mixed but generally favorable online feedback: Glassdoor shows about 3.8/5 from roughly 68 reviews with 77% willing to recommend, praising the friendly culture, onboarding, and supportive teams, while a 2025 review highlights long hours and KPI-driven pressure along with management issues.

Work environment and values appear strong, with high Culture & Values ratings (around 4.3–4.4) and Diversity & Inclusion ~4.4, plus CSR programs that emphasize mental health support, volunteering, and community initiatives, along with sustainability efforts like moving toward a paperless environment.

Financial health suggests a solid mid-sized private firm: Endole lists Harnham Group Limited turnover under £54m with under 250 employees, and Crunchbase/BGF indicate growth and investor interest in the business. (open.endole.co.uk)

Career development is mixed—onboarding and training receive praise from some, but there are frequent complaints about limited development opportunities and a removed Learning & Development function; CSR and sustainability are highlighted in official materials as strengths. Note: these insights predominantly reflect the London office with a modest public review base (roughly 68–89 reviews), so representativeness may be limited. (glassdoor.com)

What will the SEO Lead role involve and how does it fit into the company?

The SEO Lead will establish and own the SEO function from the ground up in a fast-growing AI company. You will report directly to the CMO and be the go-to expert for all things search, owning the strategy, technical implementation, and the tooling/processes needed to scale. Responsibilities include leading technical SEO initiatives (migrations, site optimizations, and troubleshooting), ensuring SEO drives growth for both consumer-facing and enterprise products, managing external agencies, and building scalable SEO infrastructure and workflows. This is a foundational, high-autonomy role with potential to lead a team in the future.

What are the must-have qualifications and experience for this role?

• Strong technical SEO expertise (highest priority) with a track record of solving complex technical issues and migrations.
• Experience in environments where SEO is a primary driver of growth.
• Ability to take full ownership of SEO strategy and end-to-end implementation.
• Experience managing agencies or third-party vendors is valuable.
• Hands-on practitioner mindset with a view toward future leadership of a team.
• Content-focused SEO background is a plus but secondary to technical depth.

What is the work arrangement and location eligibility?

• The role is 100% remote and UK-based.
• You can work from anywhere in the UK, with flexibility and alignment to UK time zones.
• Although the listing mentions London, the posting indicates remote work within the UK. If you’re outside the UK or outside business hours, please confirm during the interview how time zones and collaboration will be handled.

What is the compensation and benefits package?

• Salary up to £100,000, depending on experience.
• Benefits are referenced in the posting but are not itemized there. Details will be shared later in the process or in the offer, including standard items typical for UK tech roles (the exact benefits may include things like pension contributions, private health, etc.). You’ll learn the specific benefits during the interview / offer stage.

What is the interview process and how should I prepare?

• Step 1: Introductory conversation with the CMO to assess fit, motivation, and high-level alignment.
• Step 2: Technical assessment or discussion of SEO case studies to gauge depth, problem-solving approach, and practical skills.
• Step 3: Final interview with senior leadership to assess strategic thinking, leadership potential, and cultural fit.
• Preparation tips:
  • Be ready to discuss specific technical SEO challenges you’ve resolved (migrations, site structure changes, large-scale technical fixes).
  • Prepare quantitative examples showing impact on rankings, traffic, and conversions.
  • Demonstrate a plan for building an SEO function from scratch, including processes, tooling, dashboards, and collaboration with product and marketing.
  • Research the company’s AI products and think through how SEO could drive growth for both consumer and enterprise offerings.
