Job description
Join to apply for the Marketing Data Engineer role at Ageras Danmark
At Ageras, we are redefining how entrepreneurs—freelancers, self-employed professionals, and SMEs—manage their banking and administrative tasks with seamless tools and innovative banking solutions. Our vision is to become the best friend of every small entrepreneur across Europe. We serve over 300,000 clients with integrated solutions in accounting, invoicing, and business banking, and we’re expanding across Europe through acquisitions.
Locations: Berlin, Paris, Amsterdam — Hybrid.
As Marketing Data Engineer you are the technical engine behind our measurement stack. You ensure tracking is reliable, privacy-safe, and useful so spend decisions are evidence-based and experiments move faster. This is a hands-on role with ownership.
- Enable high-performing paid campaigns (via tROAS, CAPI, EC, etc.).
- Power platform learning and experimentation.
- Safeguard tracking integrity across apps, web, and our CDP.
If you thrive on seeing your data infrastructure directly boost campaign ROI, this role is made for you.
- Conversion tracking: Own client and server-side setups for Google and Meta and deliver a reliable baseline for attribution and reporting, including dedup between ad platforms and business data.
- Consent management: Map current consent setups per brand and ship a plan to maximise performance within compliance boundaries in DE, FR and NL.
- Own our tracking infrastructure: Manage event tracking (GA4, Segment, GTM, Firebase, MMP) across web, app, and server environments.
- Power campaign performance: Build conversion tracking and enable smart bidding via server-side integrations (CAPI, Google Enhanced Conversions, TikTok, Snap, etc.).
- Ensure data quality & attribution: Standardise conversion definitions and UTMs, implement server-side deduplication and Segment/GTM governance, and maintain a trusted cross-brand attribution baseline.
- Embed privacy & compliance: Implement Consent Mode v2, integrate CMPs, and ensure GDPR-compliant tracking practices.
- Enable cross-platform visibility: Support mobile/app tracking with Firebase or AppsFlyer and align it with web.
- Drive cross-team alignment: Collaborate with growth marketers, legal, data, and product teams to translate business needs into robust tracking plans.
- Co-own the weekly performance marketing sync and the bi-weekly tracking and measurement forum.
Tooling & Stack: GTM (client/server) · GA4 (web + SSG) · Segment (or CDP) · Firebase · Mixpanel · AppsFlyer/Adjust · Cookiebot/OneTrust · BigQuery/Snowflake · Python/SQL
You will have authority to standardise conversion definitions and reporting, plus input on tools with budget approved for consultants and stack upgrades.
- Visibility & Ownership: Your work directly impacts how we spend and scale millions in paid media.
- Tooling & Autonomy: modern stack with real decision rights on tracking and attribution tooling.
- Embedded in Growth: collaborate closely with product, data, and legal; regular updates to leadership; potential to shape growth tech at Ageras.
- Marketing or growth analytics experience with end-to-end experiments and clear readouts.
- Comfortable reading/writing code (HTML, JavaScript, APIs) for implementation/debugging.
- Experience with GTM, GA4, server-side tracking, and tools like Segment or HubSpot.
- Strong command of ad platform integrations (Google, Meta, TikTok, etc.).
- Understanding of CMPs, GDPR, and Consent Mode v2.
- Skilled in attribution modeling (multi-touch, first/last click) and customer data platforms.
- Excellent collaboration skills; comfortable with cross-functional teams.
- Fluency in English; additional languages (French or German) a plus.
- Bonus: AppsFlyer, BigQuery/Snowflake, MMM, or CCPA experience.
- Managed CDP integrations across web and mobile.
This role is not a fit for pure backend or platform engineering profiles without clear marketing experiment and measurement work.
Compensation: total compensation depends on location, experience, skills, and seniority.
