Adtech Specialist

Adtech Specialist 

We are looking for an Adtech Specialist to join our Martech team. This role will play a critical part in enabling our marketers to buy the right customers at the right value.

You’ll combine technical expertise, problem-solving, and cross-functional collaboration to make sure our adtech stack is stable, scalable, and delivering measurable impact across acquisition and re-engagement campaigns.

Key Responsibilities

Paid Media Data Enablement

• Enable the flow of first-party data into ad platforms (Meta, Google, TikTok, Branch.io, etc.) to power targeting, optimisation, and attribution.
• Support the activation of data out of ad platforms and MMPs, ensuring performance insights can be captured, reconciled, and fed back into decision-making.
• Partner with Performance Marketing, Data, and Engineering teams to configure and validate conversion APIs, event attributes, and schema alignment.
• Audit and resolve gaps in tracking, attribution, and data activation to improve match rates and optimisation signals.
• Build a repeatable playbook for scaling new data-driven use cases across markets and channels (audiences, predictive attributes, suppression, value-based bidding).

Optimisation & Capability Growth

• Test and roll out advanced features across platforms (e.g. TikTok Events API, Google Ads enhanced conversions, Meta Conversions API upgrades, Google Tag Gateway).
• Contribute to the design and implementation of a new performance marketing data schema to standardise event usage across channels.
• Champion best practice in event tracking, measurement, and campaign optimisation.
• Ensure documentation and knowledge sharing so Performance Marketing teams can self-serve effectively.

Ongoing Responsibilities

• Act as the subject matter expert for paid channel data activation (Meta, Google, TikTok, Branch.io).
• Provide second-line technical support and troubleshooting for advanced adtech issues (event mismatches, sync failures, attribution discrepancies).
• Collaborate with Engineering/Data teams to ensure pipelines, APIs, and integrations remain stable, scalable, and privacy-compliant.
• Stay abreast of industry and vendor innovation (e.g. cookie deprecation, ATT, privacy changes, new API capabilities), identifying opportunities to strengthen ClearScore’s adtech stack.

Why Join ClearScore?

• Work at the intersection of data, platforms, and digital marketing.
• Be part of a team that values innovation, learning, and impact.
• Gain hands-on experience across Meta, Google, TikTok, Branch.io, Hightouch, GTM, GA4, and CM360.
• Build skills across both adtech and martech in a global environment.

Essential:

• Hands-on experience with tag management (Google Tag Manager) and analytics platforms (GA4 or similar).
• Proven track record implementing ad platform integrations (Meta Events Manager, Google CM360, TikTok Ads Manager).
• Familiarity with MMPs such as Branch.io (or equivalent e.g. Appsflyer, Adjust) for attribution and 1st-party data activation.
• Experience using data activation tools (Hightouch, Segment, or similar).
• Technical background: APIs, data schema alignment, troubleshooting event-level data.
• Understanding of performance marketing workflows (audience creation, optimisation, attribution).
• Strong analytical and problem-solving skills, with ability to translate data issues into marketing impact.
• Excellent stakeholder management across performance marketing, data, and engineering.

Desirable:

• Experience with server-side tagging and conversion APIs.
• Knowledge of SQL for data validation and investigations.
• Exposure to privacy and compliance considerations (GDPR, ATT, data governance in paid media).
• Experience with marketing data warehouses (Databricks, BigQuery, Snowflake).
