A minimum of 5 years of relevant experience in marketing analytics, econometrics, or a closely related quantitative discipline.

Strong quantitative and analytical skills, including the ability to work rigorously with large, complex datasets and draw commercially meaningful conclusions.
Solid knowledge of media and marketing dynamics, including price and promotional mechanics and their interaction with media investment.
Advanced proficiency in Excel, PowerPoint, and Word, with the ability to produce client-ready deliverables to a high standard.
The ability to communicate complex analytical findings clearly and persuasively in writing and presentations to senior commercial audiences.
Fluency in French and a strong command of professional English.

Responsibilities

Lead the design, development, and delivery of Marketing Mix Models across a portfolio of advertiser clients, ensuring outputs are analytically robust and commercially relevant.

Identify opportunities to add value beyond immediate project scope through methodological improvement, additional analysis, or strategic counsel.
Manage client relationships, coordinate data collection, explain analytical outputs, and support clients in embedding recommendations into planning and decision-making.

Mentor and develop junior analytics team members, support their technical progression, and ensure consistent project delivery within scope and budget.

Desired Qualifications

Experience coding in R, Python, SQL, or VBA is a significant advantage and will be weighted accordingly in selection.

This role sits at the heart of Ebiquity's Analytics practice in France, working directly with leading advertisers to maximise the returns on their marketing and promotional investment. As a Senior Consultant, you will take ownership of the end-to-end development and delivery of Marketing Mix Models: translating complex, multi-source data into concise, commercially grounded recommendations that clients can act on with confidence.

This is a senior individual contributor role with genuine influence: over client relationships, analytical methodology, and the development of junior talent within the team. You will be expected to operate with a high degree of autonomy, bring intellectual rigour to every engagement, and contribute actively to the growth and reputation of Ebiquity's MMM practice in France.

Identify and pursue new business opportunities within existing client relationships, working in close collaboration with Director-level leadership.
Mentor and develop junior members of the analytics team, supporting their technical progression and ensuring consistent project delivery within scope and budget.

A minimum of 5 years of relevant experience in marketing analytics, econometrics or a closely related quantitative discipline.
Proven, hands-on experience building and validating Marketing Mix Models in a professional context -- this is a non-negotiable requirement.
Strong quantitative and analytical skills, with the ability to work rigorously with large, complex datasets and draw commercially meaningful conclusions.
Solid knowledge of media and marketing dynamics, including an understanding of price and promotional mechanics and their interaction with media investment.
Advanced proficiency in Excel, PowerPoint and Word, with the ability to produce client-ready deliverables to a high standard.
Experience coding in R, Python, SQL or VBA is a significant advantage and will be weighted accordingly in the selection process.
The ability to communicate complex analytical findings clearly and persuasively, both in writing and in presentation, to senior commercial audiences.
Fluency in French and a strong command of professional English, given the international nature of the role and client base.
