Data and Analytics Manager in Brighton

addmustard is a brand, marketing and technology agency for entrepreneurs. We add the strategic and creative fire‑power of an advertising agency, to the precision and rigour of a digital marketing agency, to the flexibility of an in‑house team. We are world‑class at creating value in our clients’ businesses and brands. We are a team of 35 brilliant brand, marketing and technology experts: a core in‑house team based in the United Kingdom (Soho and Brighton), supported by a network of specialists from around the world.

We are looking for a brilliant analytical mind, but brilliance alone isn’t enough. We need a leader. You are someone who takes deep pride in absolute accuracy and high‑level commitment. You don’t just “do” the data; you own the function. We need a “safe pair of hands” who can support the senior leadership team by providing iron‑clad insights that we can bet the business on. You are bold, energetic, and irreverent, but you are also the most methodical person in the room. You’re looking for a role where you can step up, lead the data conversation, and provide the dedicated support our fast‑paced entrepreneurial clients—and our internal teams—depend on.

The Role:

• Commitment & Leadership
• Operational Ownership: You aren’t just a contributor; you are the guardian of our data integrity. You ensure that every number that leaves the agency is 100% accurate and verified.
• Proactive Support: You don’t wait to be asked. You anticipate the needs of the founders and the strategy teams, providing the “ammunition” they need before they know they need it.
• Strategic Leadership: You will bridge the gap between technical data and commercial reality. You’ll sit with our senior team to help shape the agency’s direction through evidence‑based thinking.
• Mentorship & Rigour: You will set the standard for how data is handled at addmustard, ensuring the wider team maintains the same level of precision and commitment that you do.

We need you to:

• Forensically Lead: Own the analysis of digital marketing performance. You won’t just spot a trend; you’ll investigate the “why” and present a solution.
• Build the Infrastructure: Architect and maintain the dashboards (Looker Studio/GA4) that serve as the “source of truth” for our clients.
• Challenge & Defend: Be confident enough to challenge a creative idea with data, but also committed enough to find the data that supports a winning strategy.
• Drive Commercial Value: Understand that our clients are entrepreneurs. They need data that helps them grow, pivot, and win—not just spreadsheets for the sake of it.

Your Experience & Technical Toolkit

We are looking for a “Player‑Coach” who has been in the trenches but is ready to lead.

• 4+ Years in Agency/High‑Growth Environments: You understand the “all‑hands‑on‑deck” commitment required to help entrepreneurs succeed.
• Unrivalled Precision: A track record of delivering error‑free, high‑stakes reporting.
• GA4 & Looker Studio Mastery: You are the person others come to when they get stuck.
• Advanced Google Sheets: You treat a spreadsheet like a piece of engineering—structured, scalable, and easy for others to use.
• Communication: You can command a room. You translate complex data into “Founder‑speak” with ease and confidence.

What’s in it for you?

In return for your commitment and leadership, you can expect:

• A Seat at the Table: Your voice will directly influence the growth of the agency and our clients’ businesses.
• Full Autonomy: We trust our leaders. You will have the space to shape the data department as you see fit.
• A High‑Performance Culture: Work alongside 35 experts who are as ambitious and hard‑working as you are.
• The “addmustard” Life: Hybrid working (Soho/Brighton), flexi‑time, and a genuinely supportive, sociable team that celebrates every win.
