Join MGID as a Full-Stack Developer and become part of a team shaping the future of AdTech

You'll be working on a project focused on building a new product core — the Smartlink and Adaptive Funnels Platform.

  • Collaborate with product and marketing teams to implement new ad formats (push subscriptions, clickunders)

  • Ensure performance, scalability, and security of web and mobile applications

  • Experiment with monetization models, analytics, and user flows together with the product team


Who You Are

  • 4+ years of experience in backend development with GoLang / PHP / (PHP is obligatory)

  • 4+ years of experience with modern frontend frameworks (Angular is priority)

  • Strong knowledge of relational databases (MySQL/PostgreSQL), including query optimization and indexing

  • Experience with additional databases such as ClickHouse (analytics), Aerospike (key-value), MongoDb (object)

  • Ability to design scalable, secure, and high-load systems with caching, monitoring, and API integrations

  • Experience in developing responsive web and mobile-friendly applications

  • Familiarity with containerization (Docker, Kubernetes) and Nginx reverse proxy

  • Understanding of security practices (CORS, token auth, HTTPS, security headers)

  • Solid understanding of how the Internet works (DNS, CDN, TLS, routing, caching layers)

  • Understanding of content delivery and scalability principles (edge caching, geo-replication, CDN invalidation)

  • Familiarity with AI-powered coding assistants (such as Cursor or Claude Code) to enhance development productivity

  • Upper-Intermediate English for confident technical communication

Will be a plus

  • Experience in AdTech, affiliate marketing, or traffic monetization platforms

  • Knowledge of ML-based optimization (multi-armed bandit, Thompson sampling)

  • Experience with A/B testing frameworks and analytics pipelines

  • Bachelor's or Master's degree in Computer Science or a related field

Join us at MGID and be a key player in our innovative, results-driven AdTech team.
