Job Description

Senior Full-Stack Engineer

Wunderkind

• 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, auction logic, curation flows, and traffic-shaping or path-optimization capabilities. • Partner closely with product managers, designers, and engineers to translate roadmap items into clear technical designs, scoped milestones, and production-ready implementations. • Develop reporting and observability capabilities that improve visibility into bids, impressions, inventory, advertiser outcomes, and platform health. • Write clean, modular, testable code and uphold strong engineering standards through code reviews, documentation, and thoughtful system design. • Help shape architecture and delivery decisions around latency-sensitive systems, event-driven workflows, privacy-aware data handling, and operational reliability. • Support production readiness by contributing to monitoring, troubleshooting, incident response, and ongoing platform improvements.

Job Requirements

  • 5+ years of professional software engineering experience, including substantial hands-on experience in both backend and frontend development.
  • Strong proficiency in at least one backend language such as Go, Java, or similar, with experience building production APIs, services, and integrations.
  • Strong proficiency in modern frontend development, ideally with React and TypeScript, including experience building product configuration or operational interfaces.
  • Experience designing and integrating with RESTful APIs, event-driven systems, and service-oriented architectures.
  • Ability to model and implement business logic for campaigns, placements, segmentation, reporting, or workflow configuration in a scalable and maintainable way.
  • Solid understanding of distributed systems fundamentals, production debugging, observability, and performance considerations.
  • Ability to reason about ad-tech concepts such as supply and demand flows, SSP integrations, OpenRTB, VAST, impression / click tracking, creative metadata, privacy signals, and latency-sensitive request paths.
  • Experience working with telemetry, analytics, or event streams to power reporting and operational visibility.
  • Comfort working across the full delivery lifecycle: discovery, technical design, implementation, testing, deployment, and post-launch support.
  • Strong problem-solving skills, attention to detail, and the judgment to make pragmatic trade-offs in ambiguous environments.
  • Ability to work independently and autonomously without requiring constant supervision.
  • Excellent communication and collaboration skills.
