Hybrid | Senior Level | Full Ownership
We are not looking for a Media Buyer.
We are building the supply backbone of a next-generation on App Growth company.
Appiness is an AI-powered App Growth Partner turning app users into shoppers.
We don’t resell CPI traffic.
We build incrementality across traffic ecosystems.
Now we’re hiring the person who will own and scale our Supply-Side Intelligence Layer.
Main Responsibilities
Your Mission
Design and scale a diversified, resilient, high-margin supply ecosystem that:
- Adds differentiated traffic sources (DSPs, CTV, OEM, premium)
- Protects incrementality (our USP)
- Eliminates publisher dependency risk
- Drives new GP through strategic supply expansion
- Prevents CPI/CPA commoditization
You will decide where and how we scale.
This is a business-critical leadership role.
What You’ll Actually Do
Expand the Supply Universe
You will identify, evaluate, negotiate and activate:
- New & relevant App Networks
- Programmatic DSPs
- Performance DSPs
- CTV platforms
- OEM & device-level partnerships
- Premium / non-commoditized inventory
You understand the structural difference between:
network traffic, DSP buying, OEM supply and walled gardens.
You don’t just “test traffic.”
You architect supply strategy.
Own MMP & Incrementality Logic
You have real experience in: Adjust/AppsFlyer / Singular or similar
You understand:
- Postbacks & event mapping
- SKAN complexity
- Cohort validation
- LTV analysis
- Fraud signals
- Incrementality testing
If you only read dashboards - this role is not for you.
Deep Network & DSP Experience
You’ve worked hands-on with at least one of:
AppLovin| ironSource / Unity| Liftoff| Moloco| InMobi|Mintegral| Chartboost| AdColony|Fyber or similar.
And you understand how buying logic actually works.
You know how supply is structured.
You know what “easy scale” really means.
You know how to protect margin.
Understand the Ecosystem
You know how campaigns operate across:
Meta| Google App Campaigns| TikTok| Apple Search Ads
You understand how to compare their incrementality vs external DSP supply.
You think cross-channel.
How Success Looks Like
- New high-quality publishers onboarded
- Clear diversification (no single publisher >30%)
- Strong GP per new supply partner
- Measurable incremental revenue impact
- Strong margin protection
- A resilient supply stack
Your profile
Who You Are
- 6+ years in mobile performance ecosystem
- Strategic, commercially sharp
- Comfortable negotiating with networks & DSPs
- Obsessed with incrementality
- Skeptical of inflated scale
- Thinks in GP and enterprise value
You are not a channel specialist.
You are a supply strategist.
Not For
- Junior UA managers
- Pure Meta/Google buyers
- Campaign operators
- Arbitrage CPI traders
Why us?
Why This Is Big
You will own one of the two core pillars of the company.
Your decisions directly impact:
- Margin
- Risk

- Company valuation
This is not a job.
It’s ownership of a growth engine.
