Senior Full-Stack Engineer

About Wunderkind

Wunderkind is a performance marketing solution that uses AI and data to help brands acquire and retain customers through one-to-one, personalized messages across websites, email, text, and ads, guaranteeing a lift in revenue. Founded in 2010, our goal is to scale a brand’s ability to create and grow customer relationships through websites, email, text, and ads. We believe individuals should have the freedom to choose the kind of internet they want. An internet that fosters genuine relationships with brands. An internet that treats humans like real people instead of “web traffic.” We also believe in empowering brands to treat their customers as individuals, satisfying their unique needs with tailored experiences and thoughtful communication.

Summary

We are seeking a senior full stack engineer who can help deliver Wunderkind Advertising's roadmap across supply, demand, and platform investments. This includes building and scaling campaign placements and triggers (overlay takeovers, mastheads, in-feed, gallery / milestone units, slider placements, progress bars, ad refresh, and multiple-campaign activation), integrating SSP demand sources, improving OpenRTB-based auction flows, and evolving advertiser / publisher tooling and reporting. The ideal profile combines strong backend engineering, practical frontend product development, and fluency in ad-tech concepts and vocabulary.

The Profile We Are Looking For

• A senior engineer who can move comfortably between backend services, APIs, data / event flows, and frontend product surfaces without losing momentum in either layer.
• Someone who can reason about advertising systems using the language of supply, demand, campaigns, placements, bid requests, SSP integrations, OpenRTB, creative constraints, pacing, segmentation, and reporting.
• An engineer who can translate roadmap themes into implementation plans - for example, new ad placements, campaign-type expansion, refresh logic, segmentation controls, bulk-edit tooling, publisher workflows, and advertiser-facing reporting capabilities.
• A pragmatic builder who can operate in ambiguity, identify the right system boundaries, and ship incremental value while preserving long-term platform quality.
• Ads-space experience is a strong asset; CTV, SSP, auction, or broader ad-tech experience is especially valuable.

Role Responsibilities

• Design, build, and maintain full stack product capabilities across backend services, APIs, frontend interfaces, and internal tools that support Wunderkind Advertising.
• Implement supply-side product capabilities such as new placements, trigger logic, refresh behavior, and multi-campaign activation rules across onsite, in-app, and adjacent ad surfaces.
• Build frontend and backend workflows that support advertiser and publisher use cases, including segmentation controls, placement configuration, campaign setup, and bulk-edit or operational tooling.
• Contribute to demand-side integrations and optimization work, including SSP onboarding, OpenRTB request / response handling, and yield / pacing improvements.
