Description

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Fullstack Engineer based in Germany. This role offers the opportunity to build high-performance, user-facing applications at the heart of a global ad-tech platform operating at massive scale. You will join a product-focused engineering team responsible for the core “Console” experience, the primary interface through which users manage complex programmatic advertising campaigns and real-time analytics. The work involves translating highly complex backend systems into intuitive, fast, and reliable user experiences used across global markets. You will operate across the full stack, contributing to architecture, frontend development, and API integrations while collaborating closely with product, design, and backend engineering teams. The environment is fast-moving, highly technical, and deeply collaborative, with a strong emphasis on ownership and execution. You will also work with modern AI-assisted development workflows to accelerate engineering productivity. This is a chance to have direct impact on a product handling billions of ad requests daily. \n Accountabilities: Design, develop, and maintain fullstack features across frontend interfaces and backend integrations for a high-scale ad-tech platform. Build and enhance user-facing dashboards, reporting tools, and campaign management interfaces used for real-time decision-making. Translate product requirements into clean, scalable, and well-tested technical implementations, owning features end to end. Collaborate closely with product managers, designers, QA, and backend engineers to deliver seamless and high-quality user experiences. Participate in architectural discussions and contribute to technical decisions around system design, performance, and maintainability. Optimize frontend performance, including rendering efficiency, data handling, and responsiveness for data-heavy applications. Maintain high engineering standards through code reviews, testing practices, and continuous improvement of the codebase. Support delivery planning by breaking down requirements into actionable engineering tasks and ensuring timely execution. Requirements 5+ years of professional experience as a Fullstack Engineer working with modern JavaScript/TypeScript. Strong experience with at least one major frontend framework (React, Angular, or Vue) and its ecosystem. Solid understanding of HTML5, CSS3, responsive design, and cross-browser compatibility. Experience building complex, data-intensive UIs, ideally with real-time or analytics-driven interfaces. Good understanding of API integration, REST or GraphQL, and backend interaction patterns. Strong grasp of frontend performance optimization techniques such as caching, lazy loading, and bundle optimization. Experience with testing frameworks such as Jest, Cypress, or Playwright. Ability to work in fast-paced environments with a strong bias for shipping and iterative delivery. Comfortable working with ambiguity and contributing to product and technical discussions beyond pure implementation. Bonus: experience in ad-tech, high-scale systems, or AI-assisted development tools and workflows. Benefits Competitive compensation package. Flexible remote work within Europe. Annual learning and development budget. Home office setup allowance. Opportunity to work on a global-scale platform handling billions of daily ad requests. High-growth environment with strong technical mentorship and career progression opportunities. International, diverse team with a collaborative engineering culture. Exposure to cutting-edge AI-assisted engineering workflows and tools. \n How Jobgether works: We use an AI-powered matching process to ensure your application is reviewed quickly, objectively, and fairly against the role's core requirements.
