adjoe builds the technologies behind mobile apps growth and monetization. adjoe Ads is our programmatic in-app advertising platform that seamlessly connects advertisers and publishers through direct integration of our Android and iOS SDKs. Every ad decision happens in under 200ms across 10 million daily users, powered by real-time bidding algorithms and user quality prediction models that match the right ad to the right user at the right moment.
Where 50 Billion Daily Predictions Begin

The User Experience team is the origin point of adjoe Ads. Everything the system knows about a user, every prediction the ML models make, every bid placed in an auction. It all starts with code this team ships.

The team owns two responsibilities. On the SDK side, a native Kotlin and Swift code runs inside hundreds of publisher apps. It participates in 120 million daily auctions, renders ad creatives across multiple formats, and captures the behavioral signals that power 50 billion predictions per day. The constraint that defines this work: you’re executing inside someone else’s app, on someone else’s device, with zero tolerance for instability. Every ad impression has to feel native and fast to the user.

On the analytics side, the dashboards, investigation tools, and data frameworks that turn raw data into decisions: real-time revenue performance across active campaigns, infrastructure cost visibility, and data quality assessments. If a number matters to the business or to engineering, this team makes it accessible.

Your Mission & Who We Are Looking For:

• Auction & Marketplace Analytics: You will monitor core ad exchange KPIs—including bid rates, win rates, timeout rates, eCPM, and render rates—and run deep dives to uncover bidding patterns and supply path optimization (SPO) opportunities. We are looking for someone with 2–3 years of experience as a Data or Product Analyst in AdTech (Programmatic, Ad Exchange, SSP, or DSP) who understands what drives marketplace health and revenue.

• A/B Testing & Revenue Strategy: You will design, track, and evaluate A/B tests for product features, floor pricing rules, and traffic shaping algorithms. We are looking for a data-driven thinker who loves solving business puzzles, testing commercial hypotheses, and proving what actually moves the needle on product performance.

• Advanced Data Extraction: You will query massive datasets to turn millions of raw ad events into clear business answers. We need advanced SQL skills to effortlessly query billions of rows, spot anomalies, and translate complex metrics into clear, actionable recommendations for our product and demand teams.

• Traffic & Cost Efficiency: You will analyze bid request data to identify inefficient traffic and help product managers design smart routing rules. We need an analyst who can balance top-line revenue with operational costs, finding ways to streamline traffic (Queries Per Second) without sacrificing publisher earnings.

• Executive Dashboarding & Reporting: You will build automated, easy-to-read dashboards that give Product, Engineering, and Demand Partnerships real-time visibility into campaign performance. We are looking for hands-on experience with BI tools like QuickSight, Tableau, Looker, Power BI, or Redash to make key business numbers intuitive and accessible to everyone.

• Agile Project Execution: You will balance scheduled analytics projects with quick-turnaround deep dives when marketplace metrics shift unexpectedly. We need a hands-on, proactive analyst who thrives in a fast-paced environment and can independently manage multiple analytical priorities.
