Job Description

READY TO DO WORK YOU'RE PROUD OF?

Charlie Oscar isn't a typical agency. We're independent, AI-native, and built to help ambitious brands outmanoeuvre, outpace and outgrow the competition.

We blend data science with creativity - not because it's fashionable, but because it's how brands actually grow. The numbers give us clarity. The creative work is what wins hearts, builds brands, and drives revenue.

Every week here looks different: sharp strategic problems, high-calibre teammates, and real ownership over work that reaches some of the world's most ambitious brands. Outside the day job, there's run club, book and chess clubs, charity fundraisers, Thursday drinks, and enough team socials that work never feels like just work.

We hire for attitude and culture add first - not just experience. Curious, ambitious people who challenge how things are done, bring fresh ideas, and help shape the future of marketing.

Sound like your kind of place?

WHO WE HIRE

We look for attitude first. Smart, humble, proactive, genuinely curious - that's the shortlist. People who care about their craft without taking themselves too seriously. We build brave ideas, keep learning constantly, and make sure everyone's voice counts.

If you're already using AI to work smarter, even better.

AI

We're looking for people who use AI to sharpen their work - not replace their thinking.

You don't need to be an AI specialist. You need to be curious enough to already be finding ways to use it: faster workflows, sharper insight, better creative options, smarter decisions. We want people who ask “how can this be better?” and treat AI as a tool to elevate the craft, not a shortcut around it.

THE ROLE

Please note: we can’t sponsor visas for this role. You must already have the right to work in the UK, with no sponsorship needed now or later.

This is an entry-level role in our Marketing Science team, designed for someone at the start of their career. We’re more interested in how you approach problems than in your previous experience, and we’ll give you the training and support you need to develop.

You’ll work alongside our Data Consultants on COmpass, our marketing mix model. You’ll start by preparing and cleaning client data, then running first-pass analysis. You’ll learn the tools as you go, and the team will show you how each piece of work feeds into the decisions clients make about their budgets.

Whilst a technical background is helpful to problem solve , we will teach you the skills you will need - we want you to bring the curiosity and the drive to keep improving.

WHAT YOU'LL BE GETTING STUCK INTO

• Prepare client data for COmpass projects. You’ll pull it from Google, Meta, Shopify and other platforms, clean it and check it before anyone builds a model on it.
• Support model re-runs across multiple client accounts, delivering to the deadlines the team relies on.
• Dig into the numbers and flag anything that looks off, even before you know why it matters.
• Learn each client’s business: what they sell, who they sell to and what they need from us.
• Build your technical skills in Python, SQL and COmpass, with structured training and a team who’ll answer your questions.
• Test where AI tools can speed up your work, and check their outputs before you trust them.

WHAT WE'RE LOOKING FOR

Must-haves

• You enjoy hard problems. When you get stuck, you try a few approaches before asking for help, and you ask when you need to.
• You think logically. You can break a question into steps and explain how you reached your answer.
• You want to know why. You ask what a piece of analysis is for and who will use it.
• You learn fast from the people around you. You take feedback, act on it and come back sharper.
• You speak up. If you see a better way to do something, tell us, even in your first month.

Nice-to-haves

• You have experience building time-series regression models from scratch
• Some experience with Python or SQL,
• An interest in marketing, media or how brands grow
• A background in maths, economics, science or another numbers-heavy subject

None of these are essential. Don’t tick every box? Apply anyway. We’ll teach you the tools if you bring the thinking.

The one thing we can’t flex on: you must already have the right to work in the UK. We can’t sponsor visas for this role, so please don’t apply if you’ll need sponsorship.

BENEFITS

• Competitive salary, plus a performance-based bonus paid every 6 months
• Wellness allowance, including access to Bupa private healthcare
• Pension plan
• Regular team socials and an annual company away day
• Hybrid working - 3 days in the office, 2 dayS from home
• 25 days' holiday, plus bank holidays and flexible time over Christmas
• 2 weeks ‘Work From Anywhere’ per year
• Your birthday off
• Cycle to Work Scheme with Forest Bikes
• Eye care vouchers
• Regular office treats and surprises
• Be part of building something truly exceptional
