We are looking for a hands-on Ad Product Marketing & Creative Lead to translate our KaiKai lock screen surface into a compelling, high-impact narrative that advertisers want to buy into.

This is a dual-impact role: you will own our go-to-market strategy, sales enablement, and corporate positioning from scratch, while staying deep in creative execution—setting the quality bar, building agency guidelines, and collaborating directly on client campaigns.

Who we think this person is

Most likely you are sitting in a strategy job at a creative agency, or in brand marketing, business marketing, or platform partnerships at a media house. If you already do ad product marketing at a platform, you will recognise this job instantly, and we want to hear from you, but we wrote this for the first two.

What you'll do

Go-to-market and product marketing

• Own commercialisation for new ad formats, from first-client pilot through pilot programme to general availability
• Define target advertiser segments and the problem each format solves for them
• Write positioning, messaging and proof points, and keep sales speaking with one voice
• Package formats into sellable offerings together with the CBO, who owns the rate card and pricing logic
• Set and report success metrics for each launch: adoption, advertiser performance, revenue impact
• Act as voice of the advertiser to product, and voice of product to sales

Sales-facing material and enablement

• Own the full sales kit: decks, one-pagers, case studies, creative spec guides, objection handling
• Every case study anchored to a measurable outcome, not a description of what ran
• Train the sales team on new formats and refresh that training at each launch
• Direct external design and production partners, and own those relationships and their briefs

Creative

• Run brand collaborations end to end: concept, pitch, execution with the client's agency, sign-off
• Work with the Creative Team
• Set and hold the quality bar on everything that runs on the KaiKai surface
• Build creative guidelines and a reference library agencies can work to without hand-holding
• Put creative testing in place so format and execution decisions are evidenced rather than argued

Market

• Track competing platforms: what they offer, how they package it, what they charge
• Represent the product as subject matter expert in client and agency meetings, with the sales team
• Co-build the annual product moment with the CBO (not the first year)

Cosmose corporate marketing and communication

• Clean up corporate positioning and the public-facing basics: website, LinkedIn, company boilerplate
• Keep a regular communication rhythm so client outreach lands on a company that looks alive
• Owns the work.

KaiKai consumer brand

• With the CBO, positioning of the consumer app and the case for voluntary download

What we're looking for

• Six years or more; the title on your CV doesn't matter. Strategy, planning, brand marketing, business marketing, product marketing. What matters is what you have made, not what the role was called.
• You can take something technical and turn it into a reason a marketer cares. This is the whole job in one line. We have a surface, a set of capabilities, and no story. You build the story, then you have to defend it to someone who buys media for a living.
• You know how a brand buys media from the inside. What actually goes into an RFP. Who signs. What brand lift is and why measurement decides whether a budget grows or stays a test. If you have been on the buying side, this is your advantage, and it is the one we value most.
• You have a view on creativity, and you can give a brand feedback they will accept. Not taste for its own sake. You can tell the difference between creative that will work on a specific surface and creative that was resized from a banner, and you can say so to a client without losing the client.
• You can write about a company, not only about a product. Part of this job is making Cosmose look like a company a media buyer would take seriously. Website, LinkedIn, the basics. You do not need to have done corporate communications as a job. You need to be able to look at what we have today and say what a planner would think of it.
• Your Polish and English are good enough to run meetings with internal teams and a global client. The team is spread across Warsaw, Singapore, the SEA market, and Brazil.
• You are fine without a process. There is no playbook here yet, and you will be writing most of it.

What you do not need

• You do not need to have worked at a platform. Most of the people we are talking to have not. We can teach you pricing, ad load, measurement partners, and how OEM deals work.
• No adtech background and no technical knowledge of programmatic.
• No sales experience. There is no quota, and you will not own accounts.
• Not performance marketing. This is not a media buying or user acquisition role.

What you would be learning in the first six months

• How this inventory is priced and why. How measurement works in OEM inventory, and why it is the thing that unlocks budgets. How an OEM partnership actually operates. If none of that sounds interesting, this is the wrong job, because it is where the first year goes.

We're building something big-and we're just getting started.

If you're excited about shaping the future of AI-powered mobile content, we'd love to meet you.
