Position Overview

We are seeking a highly analytical, connection-obsessed, and systems-minded SEM Lead / Senior SEM Expert to spearhead and scale our paid acquisition strategy across our complete portfolio of applications under a permanent, full-time remote engagement framework open across Spain and broader Europe. Shifting completely away from routine ad-hoc copywriting, passive tracking checkmarks, or simple external agency oversight, you will run an active algorithmic budget engineering, high-volume keyword segmentation, and technical search automation laboratory—partnering face-to-face with product managers, data scientists, and core growth marketing pods. This position requires a quantitative performance veteran who constructs multi-layered campaign infrastructures fluidly natively using Google Ads mechanics, evaluates backend attribution health cleanly natively leveraging automated tracking models and data warehouses, and commands large-scale multi-product budget allocation frameworks confidently under strict unit-economic performance targets.

Key Responsibilities

• Core Paid Search Architecture: End-to-end management, engineering, and scaling of Google Ads Search infrastructures from scratch across our complete application portfolio, establishing robust keyword intent match-types.
• Algorithmic Bidding Optimization: Oversee Smart Bidding frameworks, optimizing conversion signal streams, tracking infrastructure, and data attribution nodes to optimize algorithm efficiency.
• Data Engineering and Script Automation: Build custom internal analytics dashboards, data pipelines, and performance-tracking automation scripts natively utilizing Google Ads and raw data warehouses (GA4, Looker Studio, and BigQuery).
• Capital Deployment and Profitability Governance: Formulate scalable system budget architectures, balancing capital distribution based on ultimate downstream unit metrics (LTV, CAC, and operational revenue impact) over vanity metrics.
• Search Term Data Mining: Lead deep, continuous query mining and negative keyword framework updates to isolate high-intent conversion pathways and eliminate capital leaks.
• Cross-Functional Product Synergy: Collaborate directly with internal data and product developers to influence application onboarding loops, subscription prompt flows, and integrate predictive tracking systems.

Required Skills & Qualifications

• Bachelor’s degree in Marketing, Finance, Business Analytics, or a highly quantitative technical field (Engineering, Mathematics, or Data Science).
• Deep, verified career history driving high-volume paid acquisition growth, showcasing advanced structural expertise specifically within Google Ads Search.
• Demonstrated capacity tracking and scaling search channels natively utilizing Google Ads data, with deep mastery over matching keyword intents, negative mining rules, and conversion signals.
• Strong quantitative independence, with a proven ability to independently query databases, write custom reporting scripts, or interface with BigQuery, Google Analytics 4, and Looker Studio ecosystems.
• Sharp financial mindset focused entirely on core unit economics, prioritizing actual profit conversions and LTV:CAC performance scales over simple CPC or CTR metrics.
• Excellent communication proficiency in English, enabling seamless strategic presentations and analytical walkthroughs across distributed product squads.
• Location Context: Position is open to experienced growth marketers working remotely from anywhere in Spain or across Europe , with optional hybrid office integration at Barcelona Tech City.

Preferred Strategic Indicators (Nice to Have)

• Prior experience optimizing paid customer acquisition pipelines for consumer mobile apps, multi-product tool utilities, or software subscription (SaaS) models.
• Operational hands-on background handling supplementary paid platforms such as Google Display Network (GDN) and YouTube Ads.
• Familiarity with prompt testing or exploring the intersection of generative AI models inside programmatic user growth pipelines.

What We Offer

• Vetted, High-Agency AI & Mobile Growth Blueprint: An exceptionally competitive baseline corporate compensation structure aligned precisely with your quantitative search engine marketing mastery, backed by a permanent employment contract.
• The spectacular professional canvas to own and scale the primary acquisition channel for a venture-backed portfolio used by millions of global consumers.
• Profound work-from-home remote parameters offering an autonomous European virtual framework, flexible schedule execution, and zero geographical office constraints.
• Access to premium, high-end production hardware configurations and technical tools tailored for your data execution velocity.
• A flat, agile startup environment led by proven elite technology founders, focused heavily on continuous experimentation, product ownership, and technical growth.
