Senior Creative Strategist

London (in-office) £70,000–£90,000
3 month contract
Full time

Most of our ads don't work.

To be fair, most ads in general don't work.

The viewer scrolls past. The idea doesn’t land. The message never gets a chance.

At Fyxer, we spend a lot of time figuring out why that happens, and what makes the rare ads people actually stop for, listen to, and click on.

We’re growing quickly, and creative plays a big role in that.

We’re looking for a Senior Creative Strategist to help us find more of those winning ideas.

Fyxer is an AI email assistant that organizes your inbox, assists with emails, and writes draft replies ready for your review.

It learns from your tone, your past conversations, and the context around your work. The result: an inbox that helps you move faster instead of slowing you down.

Our customers are ambitious professionals who build their reputation in their inbox. When they stay on top of email, they stay on top of their work.

You’ll sit within the creative team, reporting to the Head of Creative.

Your job is to turn insight into direction for the team. That means finding patterns in creative performance and customer behaviour, shaping strong briefs, and helping our designers, videographers, and copywriters produce work that actually drives growth.

You’ll work closely with marketing managers and channel owners across paid channels, but the focus of the role is creative thinking.

Study what works

• You’ll spend time inside ad platforms looking at creative performance.

• Which hooks make people stop scrolling? Which messages convert? Which audiences respond differently?

• You’ll combine that with customer research and market context to deliver hypotheses worth testing.

Write the briefs that guide our work

• Most projects start with a brief.

• You’ll write briefs that give the team a clear direction: the audience, the problem we’re solving, and the insight that unlocks the idea.

• You'll then work with our copywriters, designers, and videographers to turn that thinking into finished creative.

Run creative tests

• We run a high volume of creative tests.

• Some focus on improving work that already performs well. Others explore bigger bets: new audiences, new messaging angles, or new formats.

• For example, we might test whether a product message resonates more strongly with industries like sales, recruiting, or real estate.

• You’ll help design those tests and make sure they lead to useful learnings.

Keep creative anchored to results

• You’ll lead the strategic direction of brainstorms and review work as it moves through production.

• Craft specialists on the team focus on how the work looks and sounds. Your role is making sure the idea still answers the problem we set out to solve.

• You’ll also report back on what’s working so the next round of briefs gets smarter.

This role usually suits someone who has worked as:

• a creative strategist at a performance marketing agency

• an in-house performance creative lead

It would be great if you've done both.

You’re comfortable analysing performance directly in ad platforms and translating those insights into clear creative direction.

You’ve likely worked on accounts with large paid media budgets and understand how creative influences results at scale.

• Analysing creative performance in paid channels

• Designing structured creative testing programs

• Writing clear, actionable creative briefs

• Translating research and data into creative ideas

• Strong judgment on messaging and audience fit

• Speed of execution, the faster we turn around tests, the faster we grow

Experience using AI tools in your workflow is useful, but not essential.

Paid marketing drives a large share of Fyxer’s growth.

That means every insight we uncover can quickly turn into creative seen by millions of people.

This role exists to help us learn faster, and turn those learnings into better creative work.

We know that people from underrepresented backgrounds are often less likely to apply for roles unless they meet every requirement.

If you’re reading this and thinking, “I’m not sure I tick every box, but this sounds like the kind of work I enjoy,” we’d still encourage you to apply.

We care most about how you think: how you approach problems, find insights, and turn them into ideas that work.

This is a senior role, so relevant experience matters. But great candidates rarely fit a job description perfectly. If you believe you could do the work well, we’d be interested in hearing from you.
