Senior Martech Product Manager

Our story:

Every year millions of people are either filing their taxes in fear or giving up on their tax refund altogether. We're working on fixing that. Our intuitive app enables anyone, regardless of education or background, to file their taxes with newfound confidence.

Spread across Germany, Spain and the UK, the team at Taxfix Group with its brands Taxfix and Steuerbot, is a compassionate group of solution-finders. We speak our minds openly, and with over 400 professionals, including tax experts, developers, and IT security experts, we're rich in ideas and voices. The group has facilitated more than 3.5 billion euros in tax refunds for its customers since its founding in 2016.

Role summary

You own the marketing-technology layer behind Taxfix's growth: the conversion signals that tell ad networks who converted, the customer data that powers CRM, the consent flows that decide what we may share and with whom, and the referral program, one of the growth mechanics the team owns end to end. This is a senior individual-contributor role with no direct reports. You set direction for a small engineering team (a tech lead plus 3–4 engineers, two-week sprints) that supports four products across three markets, with Paid Acquisition, CRM, Brand and Creative as internal customers. A typical week mixes debugging a missing ad-network event, scoping a referral reward, settling a data-sharing question with Legal, and explaining trade-offs to leadership. All work, including across markets, happens in English; German is not required.

What you'll do

• Own conversion-signal engineering for paid acquisition: client-side and server-to-server events into Singular, Firebase/GA4, Google Ads and TikTok, including synthetic events, revenue values and predicted-LTV signals.

• Run the referral program as a product: reward mechanics, eligibility and fraud rules, voucher infrastructure (Voucherify), the in-app voucher wallet, entry points, and the experiments that tune them.

• Grow push and marketing-consent opt-in through permission primers, iOS/Android OS permission flows and notification preferences.

• Keep CRM data trustworthy: Braze attributes and events, Snowflake-to-Braze syncs, event-loss monitoring, and moving legacy messaging (SendGrid, Firebase) onto Braze.

• Turn consent and privacy requirements into product behaviour, and work with Legal on what data can go to which partner.

• Adapt tracking, CRM attributes and attribution to company launches, such as new subscription pricing tiers, without breaking downstream campaigns or reporting.

• Turn stakeholder requests, support escalations and spike findings into tickets engineers can start on, and decide what goes into the sprint.

• Weigh roadmap work against platform upkeep: pipeline migrations, security fixes, end-of-life SDKs.

• Design A/B tests (Eppo) and read the results for marketing and consent opt-s, and referral changes.

• Report progress, risks and trade-offs in writing to marketing leadership, including VP and C-level.

Must-have skills and experience

• Several years as a product manager owning martech, growth infrastructure or data products, setting your own roadmap with senior stakeholders.

• Hands-on mobile and web attribution: an MMP (Singular or comparable), server-to-server events, and ad-network conversion setups (Google Ads, TikTok).

• Event-tracking depth: you can define an event schema, write a tracking spec, and trace a missing or duplicated event through Segment, Google Tag Manager and the receiving platform.

• CRM data platforms, ideally Braze: custom attributes, event-triggered segmentation, data ingestion and sync quality.

• Working knowledge of EU consent and privacy: GDPR, consent mode, iOS App Tracking Transparency, and how push permissions behave on iOS and Android.

• Experimentation: framing hypotheses, choosing and configuring metrics, judging when a result is real.

• Precise writing: specs that engineers (and AI coding agents) can start on without a meeting, and concise updates and decision memos for leadership.

• Enough technical fluency to work through trade-offs with engineers across mobile apps (React Native), backend services and data pipelines, and to triage production incidents.

Nice to have

• Performance marketing experience with the main app and web acquisition channels (e.g. Google Ads, TikTok).

• Referral, loyalty or voucher programs; Voucherify specifically.

• Predicted-LTV or value-based bidding signals (e.g. Churney).

• Deep linking and deferred deep linking across ad networks.

• AI-driven CRM orchestration (Aampe) or creative asset tooling (Frontify, AI creative tagging).

• Building AI agents or automation for product and engineering workflows.

• Querying data yourself in SQL (Snowflake), and familiarity with dbt and Airflow.
