About the Role

Role Overview

We’re seeking a seasoned engineer to drive technical integrations for our identity and data management platform.

You’ll take full ownership of client-side JavaScript tags, server-to-server interfaces, and adserver integrations, ensuring seamless deployment for publishers and partners.

Key Responsibilities

  • Collaborate directly with publisher engineering teams to onboard and troubleshoot tag integrations
  • Develop and support key-value integrations with major ad servers including Google Ad Manager and Xandr
  • Architect and deploy high-performance server-to-server integrations with DSPs, identity providers, and ad platforms
  • Build and manage pixel-based tracking for campaign attribution and measurement

What We’re Looking For

You have a strong background in adtech systems and deep experience in JavaScript and Python. You’ve worked at a publisher, data provider, or supply-side platform and understand the operational realities of real-time bidding, identity resolution, and tag delivery. You’re comfortable owning technical integrations from design to production.

Required Skills

  • Degree in Computer Science or related field, plus 5+ years of hands-on engineering experience
  • Expertise in JavaScript and Python, with a focus on performance-critical, production systems
  • Proven experience integrating with ad servers such as Google Ad Manager or Xandr

Preferred Background

  • Experience with identity graphs, ID resolution, or cookieless identity frameworks
  • Familiarity with privacy compliance standards such as TCF and consent management platforms
  • Proficiency in Rust, particularly in backend or performance-sensitive contexts

Work Environment

This is a freelance position at 80–100% capacity, initially for six months with a clear path toward full-time conversion. Work can be conducted remotely within ±4 hours of Central European Time, or from our offices in Zurich or Berlin. You’ll join a technically strong, collaborative team building infrastructure for a more private web.
