Growth Product Builder – Performance Marketing

Entain is looking for a hands-on, execution-focused Growth Product Builder to take complete operational ownership of creating and optimizing landing pages for our global performance marketing channels. In this role, you will be the direct engine behind the gateways handling hundreds of millions of dollars in marketing spend across premier brands like bwin, Ladbrokes, Coral, and PartyPoker.

This is not a traditional, hands-off management role. You will be a hybrid builder, someone who started in frontend web development (HTML, CSS, JS) and has a sharp eye for conversion rate optimization (CRO) and design. You will work directly with performance marketing stakeholders, brand managers, and design teams to take brief requirements and personally build, code, and launch innovative landing pages directly inside our Sitecore CMS framework.

By aggressively utilizing cutting-edge AI generation tools, you will act as a force multiplier—rapidly executing layouts, copy variations, and functional tests on your own without waiting for central development queues.

• The Technical Foundation: Strong background in core frontend development (HTML5, CSS3, vanilla JavaScript). You must be completely comfortable looking at, writing, and debugging web code.

• The Growth Shift: Experience in a Growth, CRO, or digital production role where your success was measured by hard conversion metrics (CVR, CTR), not just task completion.

• CMS Execution: Direct experience authoring, structuring, and launching digital assets within enterprise CMS platforms (Sitecore experience is highly advantageous)[cite: 1, 2].

• AI Tool Pro: Mastery of prompt engineering and AI development workflows to accelerate layout generation and asset production.

• Speed & Autonomy: An entrepreneurial mindset. You thrive on being the single bottleneck-remover who can turn an idea into a live, multi-geo web asset in the same day.

Key Performance Indicators (KPIs)

• Funnel Conversion Rate (CVR) Lift: Measurable growth in user registration and first-time deposits down the acquisition funnel.

• Production Velocity: Drastic reduction in time-to-market from creative handoff to a live, compliant, public-facing URL.

• Autonomy Rate: Ability to deliver complex, high-converting layouts independently without relying on core engineering sprint cycles.
