Job description

VAST is hiring a Creative Strategist to own creative strategy end-to-end for a portfolio of fast-growing DTC eCom brands — turning performance data, buyer insight and cultural trends into ads that convert across Meta.

VAST (Vast Media Marketing) is a growth partner for eCom brands providing performance & creative services. From direct-response video, statics, UGC & partnerships for 8 figure eCom brands, and we use AI across the whole production pipeline.

You’ll work hand-in-hand with our wider team, strategists, editors, designers and coordinators. This role is equal parts storyteller and strategist: you love ideas, but you care most about whether they perform. You’ll also bring real AI and tooling ability, and use it to make the whole creative function faster and sharper.

Why this role exists

Our creative output only scales if creative strategy is owned by people who obsess over the craft. This seat exists so creative strategy runs to a consistently high standard on every brand.

As a Creative Strategist at VAST, you are:

• The person who owns creative strategy end-to-end for your brands — research, briefing, direction and overall quality
• Someone who thinks about the buyer first: who they are, what moves them, and what the creative must do to convert them
• The bridge between performance data and production, making sure the team produces the right creative, not just more creative

You’ll start by learning our systems and frameworks, then grow into full ownership of your own brands.

What you’ll own

• Creative strategy for your brands: creative direction, research, angles and briefing across your assigned accounts.
• Creative quality: the standard of what ships — briefs that are clear and on-strategy, with authority to send back work that isn't right.
• Performance-informed creative: making sure creative decisions are shaped by what the data says is working and failing, in partnership with Growth.
• Creative testing: planning, launching and learning from tests, so every iteration is intentional and learnings are captured.
• Brief-to-delivery flow: briefs moving cleanly through to production, working directly with editors, designers and coordinators, on time.
• AI tooling within creative: building and improving the tools that make creative work faster and better.

What you’ll do

• Research: dig into brands, audiences, competitor ads, customer reviews and cultural trends to find new angles and opportunities.
• Buyer avatars and angles: build sharp avatars and messaging — who's actually buying, what moves them, and where the opening is versus competitors.
• Briefs and scripts: write detailed, structured static, video and UGC briefs and scripts that give editors, designers and creators everything they need.
• Creative review and QA: review edits against strategy and the quality bar, give clear and actionable feedback, and keep revision cycles low.
• Performance analysis: track creative performance to find winning hooks, formats and stories, and tie creative to CTR, CVR, CAC, ROAS and MER.
• Creative roadmaps: build weekly plans and roadmaps for your brands, looking several weeks ahead, including strategy for new product launches.
• Iteration: spot what's already working in an account and reuse, adapt or combine assets into fresh variations.
• Coordination: manage timelines with editors and designers so work is delivered on time and to a high standard.
• Documentation: capture what works into repeatable frameworks, briefs and SOPs in Notion.

AI and tooling

AI is part of this job, not a side project. You’ll build and refine practical AI tools that speed up creative and research work — brief accelerators, avatar and research generators, and similar.

• Scope each build with the team so it fits our existing infrastructure and doesn't duplicate what we already have
• Get input from strategy, growth and editing leads as you go
• Use AI to raise the quality and speed of the work, while still owning the thinking yourself

The clearer you are about what you’re building and why, the more scope and budget opens up.

You should have

• 2+ years in creative strategy or performance advertising (agency or brand-side)
• A strong portfolio of ads or campaigns that shows creative and strategic thinking
• A solid grasp of performance metrics and how creative moves them
• An eye for what makes a great ad — strong hooks, storytelling and scroll-stopping design
• Confidence writing briefs, directing designers, editors and UGC creators
• AI ability - you've built or used AI tools to speed up real work & create leverage for yourself
• Clear, confident communication with both clients and teammates
• Organisation and reliability across multiple projects and deadlines

What success looks like

• Clear, intentional roadmaps led by performance insight — testing is structured, learnings are captured, and iterations have a reason.
• A smooth creative workflow — briefs and feedback are clear and actionable, and revisions are kept to a minimum.
• Better ads, better accounts — your creative measurably improves performance over time, which means happy clients.
• This role is ideal for someone who wants to work with fast-growing DTC brands and take pride in ads people actually want to watch.
