Senior Fullstack Engineer Node.js Media & AdTech

Braver IT S.A. Remote 2026-11-05

Requirements

  • 4+ years of professional software engineering experience, including running production systems.
  • Strong Node.js/TypeScript (or a comparable language) with a backend focus.
  • Strong React experience. You will build and maintain the customer-facing interfaces around these services, so this is a fullstack role rather than a backend-only one.
  • Solid, hands-on AWS experience: ECS/EKS, RDS, SQS, CDK, MediaConvert, CloudFront. You should be able to name the services you have used, explain what you built with them, and be comfortable helping out on the infrastructure side at scale.
  • Practical experience with media: video and image processing, media delivery, and embedding web content or players into different interfaces (apps, news websites, e-commerce).
  • Experience taking a product from idea to production ownership, including monitoring, iteration and long-term maintenance.
  • Strong computer science fundamentals and software engineering best practices.
  • Experience building systems that handle structured but skewed and noisy data.
  • Experience with AI-enabled development as part of your everyday workflow.
  • Based in Europe and comfortable working in an English-speaking, distributed team.

Nice to have

  • Experience in ad tech or programmatic advertising (real-time bidding experience is not required).
  • Real-time or low-latency backend systems.
  • Media delivery and format optimization at scale.
  • Rust.
  • Python.
  • Background in a publisher, media or ad-serving company.

What we offer

  • Multisport card.
  • Private healthcare.

  • Direct impact on advertiser outcomes and company revenue.
  • Modern AI tooling as part of your daily engineering workflow.
