Paid Search Specialist (Freelancer)
We are looking for a Freelance Paid Search Specialist with strong expertise in SEM and CRO, and a passion for converting in-market demand into high-quality sales opportunities. With this position, you will work in the Demand Capture Squad at our office in Barcelona, activating and optimising bottom-of-funnel campaigns to maximise pipeline contribution from ready-to-buy audiences.
You will join a dynamic, cross-functional team and report to the squad’s internal digital marketer, working in close collaboration with the Inside Sales leads, Product Owner, and the central creative/design team.
What you’ll be doing:
You will own the paid activation and CRO layer of bottom-of-funnel campaigns targeting high-intent keywords, retargeting engaged audiences and optimising the conversion experience from click to lead. Your efforts will directly fuel the sales pipeline with qualified opportunities while ensuring cost efficiency.
Plan, launch, and optimise Search/SEM campaigns (Google Ads, Microsoft/Bing Ads incl PMAX) with a focus on high-intent keywords and strong conversion performance.
Drive conversion rate optimisation (CRO) by refining lead forms, CTAs, and product landing pages in collaboration with our CRO expert, internal digital marketer, designers and developers.
Track and report on BOF performance KPIs, including CPL, cost per opportunity and lead quality.
Recommend tactical adjustments to improve inbound lead quality, sales conversion rates and budget efficiency.
Coordinate test-and-learn experiments with the internal digital marketer to validate messaging, creative and audience improvements.
You will report to the internal digital marketer within the BOF Squad.
Operate within the squad's agile processes, maintaining clear task ownership and feedback loops to ensure smooth coordination.
Who are you?
You are already set up in Spain to work as a freelancer in Barcelona, either as a self-employed contractor (autónomo) or through your own services company (SLU), and can invoice us directly under one of these legal forms.
You bring 3–5+ years of hands-on SEM experience running and optimising Google Ads and Microsoft/Bing Ads campaigns (including Performance Max) for B2B lead generation.
You leverage AI and automation to work smarter.
You understand the full conversion journey, spotting friction points from ad copy to landing page and applying CRO best practices to continuously improve results.
You’re data-driven and ROI-focused, confident with analytics tools (GA4 or PIWIK Pro, Looker Studio, Supermetrics) to measure CPL, cost per opportunity, and lead quality.
You thrive in an agile, collaborative environment, comfortable working in cross-functional squads and using tools like Jira and Confluence to stay aligned and transparent.
You communicate clearly and proactively, sharing insights and recommendations that help marketing and sales teams hit their pipeline and revenue goals.
You’re a self-starter who loves testing and learning, bringing creative ideas for messaging, bidding strategies, and audience targeting while maintaining cost efficiency.
You’re detail-oriented and organised, able to juggle multiple campaigns, track experiments, and document learnings for continuous improvement.
