• 2+ years of hands-on experience with Facebook Ads in Gambling/iGaming;

• Strong understanding of the full traffic funnel and key performance metrics;
• Experience independently launching and optimizing Facebook campaigns;
• Experience managing and scaling significant traffic volumes;

• Experience with Binom, Keitaro, or similar tracking platforms;
• Understanding of BMs, advertising accounts, and the general Facebook buying infrastructure;
• Strong analytical mindset and ability to make decisions based on data;
• Ability to identify problems quickly and take ownership of the result;
• Practical experience using AI tools in media buying, analytics, or workflow optimization;

WHY YOU'LL LOVE IT HERE:

• Flexible working hours and a remote work setup, so you can plan work around your life and not your life around work!
• Unlimited vacation days and paid sick leave—because your rest matters.
• A competitive compensation that truly reflects your skills and expertise.

About the Role

InterLink is seeking an experienced Project Manager with the background in software development and IT to join our Project Management Office (PMO). Our PMs are responsible for end-to-end project delivery across various sectors. They collaborate closely with clients, developers, and stakeholders, ensuring smooth project execution using Agile methodologies, particularly Scrum.

Responsibilities

As a Project Manager at InterLink, you will:

• manage project delivery from initiation to closure;
• define project scope, goals, and deliverables;
• plan and manage project resources;
• oversee Agile ceremonies (daily stand-ups, sprints);
• manage client communication and expectations;
• ensure timely delivery and alignment with client requirements.

What We Offer

InterLink offers the right candidates:

• a contract-based cooperation;
• work in a dynamic, motivated team;
• opportunities to manage diverse and impactful projects;

Expectations

This is what is expected from the successful candidate on this position:

• Long-term Commitment. Our projects are usually long-term. That's why we ask our team members for a minimum of 1 year commitment from their side.
• Full-time Work. Our customers expect us to work full-time on their projects, so we kindly ask our team members the same. On average this means 40 hours per week.
