Job description

Задачи:

• Design the architecture of an advertising SDK for integration with Windows applications (Win32/UWP) and interaction with our proprietary SSP, including mechanisms for requesting, receiving, and displaying ads, as well as collecting impression, click, and other user interaction events.
• Define requirements for SDK performance, reliability, security, and compatibility with various applications, lead its technical implementation, and ensure its future development and support for additional platforms.
• Design and launch an SSP to sell advertising inventory from our own games, with the subsequent addition of third-party publishers, including the implementation of ad auctions, inventory management, placement rules, floor prices, and ad formats.
• Design SSP integrations with existing mediation solutions, ad exchanges, external DSPs, and other demand sources, as well as technical solutions for publisher onboarding, application and ad placement configuration, reporting, settlements, and traffic quality control, with the ability to expand beyond Windows.
• Design the architecture for purchasing ad impressions and managing advertising campaigns, including budget, audience, creative, and frequency cap configuration, bidding logic, pacing, and campaign optimization.
• Ensure campaign performance measurement and reconciliation of results with advertisers and publishers, and evaluate the feasibility of developing DSP components in-house versus using partner solutions.
• Define the target architecture of the AdTech platform, technical roadmap, and phased launch plan; design API and RTB integrations based on "OpenAPI", "OpenRTB", and relevant industry standards, ensuring low-latency RTB auctions, high availability, scalability, observability, and protection against ad fraud.
• Design the architecture of event collection, analytics, reporting, billing, and data reconciliation systems; define approaches to ensuring ad creative quality and supply chain transparency; collaborate with Game Development, Analytics, Ad Monetization, Product, and Marketing teams; and build and develop the engineering team as the platform grows.

Требования:

• Have experience in architectural design and documentation of complex systems using established approaches and notations (C4 Model, UML, architecture diagrams, ADRs).
• Have experience designing and developing SSPs, ad exchanges, DSPs, or other RTB platforms, including hands‑on experience taking at least one side of an advertising platform from architecture design through to production, and strong technical experience with the other side.
• Be familiar with OpenRTB 2.x, have experience integrating with DSPs, SSPs, or ad exchanges, and understand how ad auctions work, including bid requests and bid responses, floor prices, timeouts, win/loss notifications, and billing notifications.
• Have experience working with SSP functionality, including inventory management, publisher onboarding, mediation, external demand sources, and revenue optimization.
• Have experience working with DSP functionality, including advertising campaign and budget management, targeting, bidding, pacing, optimization, and performance measurement.
• Have experience designing backend architectures, event streams, reporting systems, and financial reconciliation systems, and understand distributed backend architectures, network protocols (HTTP/HTTPS, TCP/IP), APIs, caching, and the principles of building high-performance web services in cloud environments (AWS/GCP/Azure).
• Be familiar with advertising formats and technologies (Display, Video, VAST, VPAID, MRAID, HTML creatives), ad quality control practices, fraud detection, advertising inventory protection, and advertising supply chain transparency standards (ads.txt, app-ads.txt, sellers.json, SupplyChain object).
• Demonstrate technical leadership skills, including the ability to justify architectural decisions, assess risks and development costs, set priorities, and develop an engineering team.
• Have a working level of English sufficient for negotiations with international partners and reading technical documentation.
