Director of Strategic Finance - Marketing

📍 Czech Republic – hybrid role (2 days per week in our Prague office)

Groupon is looking for a Director of Strategic Finance to become the financial architect of our Demand Engine. This role reports directly to the CFO and partners closely with our CMO. Your job is simple to say - and hard to do: Turn marketing spend into provable, incremental growth. If you believe finance should help the business decide what to scale, what to stop, and why, this role was built for you.

We are moving beyond last-click attribution, blended CAC, and static reporting.

Marketing and Product need:

• Clear visibility into incremental impact

• Confidence in cohort quality and unit economics

• Fast, defensible decisions on where to invest tens of millions - and where not to

You will build the financial truth that makes this possible.

• Create an integrated demand model linking customer segments, channels, surfaces, and P&L

• Establish a clear New vs Returning customer lens across major cohorts

• Own demand-side planning with bottom-up assumptions tied to acquisition and retention

• Define marginal ROI frameworks and channel hurdle rates

• Set testing and incrementality standards using holdouts and experiments

• Drive real budget reallocations based on evidence, not averages

• Standardize cohort-level LTV and CAC by channel, category, geography, and customer type

• Shift the narrative from cost per transaction to lifetime contribution margin

• Deliver category- and geo-level contribution margin visibility

• Classify the portfolio into Invest / Maintain / Fix or Exit

• Partner with Pricing and Promotions to separate incremental demand from subsidized behavior

• Act as finance owner for unified revenue monitoring

• Lead the financial narrative in Weekly and Monthly Business Reviews

• Turn signals into decisions within 24 hours

• You care about causality over correlation

• You don’t just analyze data — you build systems and playbooks others can run

• You are a trusted sparring partner to CMOs and growth leaders

• You are comfortable saying “stop” as confidently as “scale”

• When trends break, you land with a clear so what and now what

• You work AI-first, using AI as a daily accelerant for analysis, modeling, and documentation

• Senior experience in Strategic Finance, Growth Finance, or Marketing Finance

• Background in marketplace, ecommerce, or high-volume B2C

• Hands-on exposure to attribution and incrementality testing

• Strong data fluency and partnership with BI and Data Science

• Proven ability to influence executive-level decisions

• Track record of improving contribution margin through capital allocation
