The Opportunity:

Are you a technical SEO expert ready to make a global impact?  

At Avantor, we power the world’s most critical innovations in science—and we’re looking for a Technical SEO Specialist to help amplify that mission. You’ll be the architect behind how the world discovers our digital content: optimizing performance, streamlining structure, and engineering solutions that scale across regions, languages, and platforms.  

If you thrive at the intersection of data, development, and digital visibility, let’s shape the future of discovery together. 

What we are looking for: ​  

Several years of professional experience in technical SEO with large-scale B2B or e-commerce platforms. 

Deep understanding of how search engines render, index, and rank content. 

Hands-on experience with JavaScript-heavy environments, modern CMSs, and server-side rendering. 

Strong coding and analytics chops—think crawl stat parsing, schema deployment, and automation scripts. 

Clear, strategic communication—especially across dev, content, and product teams. 

How you will thrive and create an impact:  

Lead full-scale SEO audits across international sites to optimize crawlability, rendering, Core Web Vitals, indexation, and semantic structure. 

Design and execute scalable SEO strategies that align with UX, infrastructure, and multilingual goals. 

Translate technical SEO needs into developer-ready requirements—structured data, hreflang, canonical tags, sitemaps, and more. 

Use advanced tooling and scripting (Python, SQL, JavaScript) to automate audits, analyze log files, and surface performance insights. 

Serve as SEO lead in cross-functional projects: site migrations, platform changes, CMS redesigns, and global launches. 

Stay ahead of search trends (AI SERPs, headless CMS, structured search) and champion innovation across teams. 

Tools You’ll Use: Screaming Frog, DeepCrawl, Ahrefs, GSC, Sitebulb, New Relic, Datadog, Lighthouse, Looker Studio, Tableau, Power BI, GA4, Python, SQL, and more. 

Our commitment to you:  

 We value your time off, through flexible working hours and a hybrid setting, 24 vacation days, and an extra paid day off on your birthday!  

Enjoy a modern work environment with amenities such as free coffee and tea, an office massage chair, PlayStation, and a library.  

Your well-being is important to us. We support it with meal vouchers, gift vouchers, our Benefit Online Platform, and many others.  

We care for you and your loved ones through a private medical insurance and Employee Assistance Program.  

We empower you with learning and development opportunities to grow your career. Participate in in-house trainings, learn a new language or explore thousands of educational videos through LinkedIn Learning.  

We know you have some amazing friends, so you also receive a reward for referring people you like.
