  • Experience with CMPs/consent management platforms such as Didomi, Cookiebot, OneTrust, or Usercentrics.
  • Familiarity with GDPR, DMA, Consent Mode V2, vendors/purposes, and consent-aware implementations.
  • Comfort validating consent behavior directly in DevTools and browser requests.
  • Understanding of hashing, normalization, formatting, and match quality concepts related to conversion APIs and attribution systems.
  • Comfortable using browser DevTools to inspect network requests, payloads, cookies, local storage, request headers, and API calls.
  • Hands-on debugging mindset; able to reproduce and troubleshoot issues independently.
  • Experience with online payment systems such as Stripe or similar gateways and payment attribution flows.
  • Fluent English, written and spoken; Spanish is a plus.
