About Us

At Assembly, our mission is to find the change that fuels growth. We apply this principle to the work we do with our clients and to how we engage with our people. We’re a modern global agency bringing together media, data, technology and talent to make brands perform.

Our business is purpose driven. In March 2022, we were named Ad Age’s first ever Purpose-Led Agency of the Year, recognised for our mission to leave the world better than we found it. This year we became B Corp certified, the result of a two-year journey. We’re proud to have created a culture where diversity of thought, experience, and background are valued, within an environment that fosters continuous learning, adaptability, and a shared passion for meaningful impact.

When you join Assembly, you become part of an award-winning global community of digitally led experts, home to 1,500 talented people across 25 offices globally. Together we create unique data, technology and media solutions that enable faster and smarter problem solving within an inspired, collaborative workplace.

Assembly is poised for its next chapter of growth. We’re a meritocratic, high-performance business with a progressive outlook and a growth mindset in all that we do. To realise our potential we need some new skills and thinking.

The core DNA of Assembly lies in digital performance marketing. New and existing clients are asking us to extend this expertise across all media, connecting traditional channels with digital methods of execution, measurement and automation. We were born the right way to do this – we’re building out from a leading digital and technology capability and adding the rest, rather than trying to reverse engineer a legacy business into a more modern version of itself. At Assembly we ask our people to embody three core values:

Show Up: actively contribute to a space of personal and collective growth

Make Change: embrace obstacles as opportunities, taking intentional steps to drive positive change

Win Well: approach success with integrity, responsibility, and a commitment to collaboration, understanding that the journey is as important as the destination.

We look forward to meeting you and to discussing how we can grow together.

Overview

We’re looking for a well-rounded Technical SEO Manager to join our European HQ in Central London. With a strong agency background and solid technical SEO knowledge, you’ll play a key role in delivering results-focused technical strategies and fixes that align with business goals and elevate organic performance.

In this role, you’ll work with clients in the luxury fashion and travel sectors. As we’re an SEO team that specialises in international SEO (100% of our clients are multi-market), you must be comfortable and have experience with international optimisation tactics (particularly hreflang tags).

Working with our Technical SEO Lead, you’ll collaborate closely with the wider SEO and Paid Search teams, ensuring campaigns are aligned, integrated, and executed flawlessly.

Responsibilities

• Work closely with the Technical SEO Lead (account director) to conduct technical audits and support the implementation of fixes.
• Manage client migrations and work closely with the Tech SEO Lead and our wider team to service these projects in a consistent and effective manner, ensuring all deadlines are met.
• Manage technical projects and tasks for clients.
• Work closely with client dev teams and submit Jira tickets to get tasks implemented, and troubleshoot how to implement if there are internal dev resource issues or technical limitations.
• Continue to develop your knowledge within the digital industry and future of search.
• Participate in new business work when required, taking ownership and ensuring delivery of the areas you have been assigned.

Required Skills

• 3-5 years’ experience in SEO, with a minimum 2 years within an agency environment.
• A strong background in technical SEO, with experience optimizing websites to enhance user engagement and drive business performance.
• Strong attention to detail, excellent analytical brain, numeracy understanding with strong emphasis on statistical data.
• Strong experience working with Shopify, Salesforce, and other e‑commerce CMS’s.
• Prior experience working closely with dev teams. Some coding experience would be a bonus, including an understanding of JavaScript.
• Natural curiosity and someone who loves solving an SEO puzzle.
• Experience with complex, large‑scale international e‑commerce sites.
• Experience managing and supporting a direct report.
• Proven experience with technical audits and website migrations.
• Solid understanding of SEO tools (e.g. Google Search Console, SEMrush, Sitebulb, Screaming Frog) and experience uncovering insights and creating a helpful strategy for clients.
• Experience in accurately reporting and measuring SEO in a way that clients can understand and report back to senior leadership.
• Excellent communication and presenting skills, including written & spoken English.
