The role

We are looking for an experienced BI Developer with extensive experience in BI tools like Power BI, Tableau, Qlik Sense, or similar. Expertise in data modelling and storytelling is essential, together with stakeholder management skills and a problem‑solving mindset. This position requires a combination of robust technical expertise and effective interpersonal skills, as independent end‑to‑end project execution is expected.

This is a rewarding opportunity to work with an innovative organisation in a growing team. Exposure will go beyond technology and focus on outcomes‑driven solution implementation in an array of verticals. While the position is in the BI Practice, it will offer regular exposure to all areas of the business by virtue of the role. The BI Developer role will serve both internal and external customers and therefore be client facing.

Your working time will be split between our offices, work at client sites, and remotely (from home) for Merkle’s valued clients.

What you’ll do

• Develop & maintain BI solutions – design, build, and optimize dashboards, reports, and data pipelines using tools like Power BI, Tableau, or Qlik.
• End‑to‑end project delivery – work on BI projects from scoping and data extraction to visualization and stakeholder training.
• Ensure data accuracy & security – work with data engineers to maintain data integrity and comply with industry regulations.
• Work closely with clients – gather requirements, present insights, and provide recommendations to clients and internal teams.
• Stay ahead of new BI tools & features – continuously explore new technologies and industry trends, including AI & augmented analytics, to improve our data capabilities.
• Contribute to development of the team – help develop more junior team members with technical support and guidance, share details of recent project solutions, and conduct bi‑weekly team catch‑ups.

What we are looking for in you

• 3+ years in a data/reporting analyst role – preferably in an agency, consultancy, or client‑facing environment.
• Proficiency in reporting tools – Power BI, Tableau, Qlik, SQL, and Excel.
• Strong problem‑solving skills – the ability to translate data into actionable insights.
• Interest in AI‑assisted analytics – demonstrate comprehension and articulate knowledge of emerging augmented analytics features, including Copilot, Insight Advisor, and Tableau Pulse.
• Excellent presentation and storytelling skills – simplify complex data topics for diverse audiences.
• Ability to manage multiple client accounts – stay organized and meet deadlines efficiently.
• Knowledge of industry metrics – familiarity with key performance indicators (KPIs) in marketing, finance, or other relevant industries.
• Project management skills – familiarity with an array of project management techniques and tools.

A few of the benefits

• You’ll have a great compensation package, private health & dental insurance, corporate discounts and career development through Dentsu University, and free access to LinkedIn Learning.
• 29+ days of annual leave (25 days of regular holidays, birthdays off and 3 additional wellness days).
• We also offer the opportunity to volunteer for up to 2 days per year and tend to close down the agency between Christmas and New Years.
• You’ll have a hybrid working schedule, with flexible start/end hours.
