Job description

At CELO, we are leaders in high-precision technical screws and fixing solutions for construction and industrial manufacturing. We strongly believe that the \"Small Things Matter\". This philosophy doesn’t just apply to our products; it guides how we handle our processes, our relationships, and our data.

We are looking for a highly autonomous practitioner with a strong technical backbone who can roll up their sleeves and audit, structure, and optimize our ecosystems without needing a long hand-holding period. If you thrive on transforming complex, multi-country data streams into clean, actionable growth strategies, this is your role.

What will your responsibilities be?

• Data Governance & Analytics: Audit, structure, and scale our GTM and GA4 setups across international sites. Establish strict naming conventions and measurement frameworks to maintain data hygiene across markets.
• CRM Automation (HubSpot): Design and manage advanced B2B nurturing workflows, optimize database segmentation, and build closed-loop pipeline attribution models.
• Performance Marketing (Paid Media): Plan and scale paid acquisition (Google Ads, LinkedIn, Meta) across multiple countries. Manage ad budgets, run continuous A/B tests, and lead and coordinate our international subsidiaries in the development and execution of their local digital campaigns, ensuring alignment with global strategy and measurement standards.
• Reporting & Dashboards: Connect HubSpot, GA4, and ad networks into clean dashboards (Looker Studio/BI) that provide actionable insights to corporate leadership.

What are we looking for?

• 5+ years of experience in hands-on Web Analytics and Performance Marketing.
• Advanced HubSpot Expertise: Practical experience in building complex workflows, custom reporting, and database cleaning is mandatory.
• Tracking Mastery: Deep technical knowledge of Google Tag Manager (GTM) and GA4 (debugging, custom events, variables).
• The \"Order\" Mindset: A proactive professional who builds structured tracking systems and clean databases rather than letting them run into chaos.
• Bilingual English & Spanish (essential for coordinating with global subsidiaries).

Nice to have

• Prior B2B industrial or multinational corporate experience.
• Intermediate knowledge of SQL, Looker Studio, or Power BI.
• Active HubSpot, GA4, or Google Ads certifications.
• Leadership & autonomy: proven ability to propose, execute, and follow through on projects independently, including coordinating teams or stakeholders across subsidiaries.

Are you passionate about digital marketing and motivated to work on international projects? Are you interested in combining creativity, analysis and strategy to strengthen the digital presence of an industrial company?

We would love to get to know you. Apply for this position and choose a dynamic, international company that keeps growing.

At CELO, cohesion and teamwork are some of our core values. We embrace a diverse and inclusive culture that promotes equality and offers opportunities to everyone.
