Synthesized is transforming how the world tests software with AI.

Trusted by global leaders like Deutsche Bank, UBS, and the European Commission, our AI-powered platform enables teams to generate high-quality test data and test cases in seconds—slashing costs, accelerating delivery, and eliminating reliance on production data.

We're a VC-backed company supported by top investors. With strong traction across financial services, healthtech, and telecom, and a $90B+ market in sight, we're scaling fast in 2025 and beyond.

? The Role

Synthesized is building the future of Testing Infrastructure — a new category that replaces fragile testing tools and manual workflows with scalable, intelligent systems built for continuous delivery.

We’re looking for a Demand Generation & ABM Marketing Manager to take the lead in how we identify, engage, and convert our highest-potential prospects into long-term customers. This role is ideal for someone who thrives at the intersection of data, creativity, and execution — someone who knows that great campaigns start with deep customer understanding and end with measurable business impact.

As our first dedicated demand marketer, you’ll work cross-functionally with Sales, Product Marketing, and the Executive Team to shape our pipeline strategy, design full-funnel campaigns, and execute account-based motions that drive growth. You'll play a key role in amplifying our category story, delivering quality opportunities to Sales, and ensuring our GTM efforts are aligned with the market we’re shaping.

This is a high-impact, high-ownership role for a marketer who wants to help define the go-to-market machine of a category-defining company — and isn’t afraid to build while scaling.

What You’ll Be Responsible For

? Demand Generation and ABM Strategy & Execution

• Develop and implement multi-channel demand generation campaigns (email, paid media, SEO/SEM, webinars, events) to drive qualified leads and accelerate pipeline growth.
• Optimize the marketing funnel by analyzing conversion rates and implementing strategies to improve lead quality and velocity.
• Manage and allocate the demand generation budget effectively to maximize ROI.
• Collaborate with Sales to identify high-value target accounts and develop personalized marketing strategies to engage key stakeholders.
• Execute 1:1, 1:few, and 1:many ABM campaigns, tailoring content and messaging to specific account needs and pain points.
• Work closely with Sales to ensure seamless lead handoff, establish lead scoring criteria, and develop joint campaign strategies.
• Provide Sales with the necessary tools, content, and insights to effectively engage and convert leads.
• Regularly review campaign performance with Sales to identify areas for improvement and collaboration.

? Analytics & Optimization

• Track and report on key performance metrics (MQLs, SQLs, pipeline contribution, conversion rates) to assess campaign effectiveness.
• Conduct A/B testing and use data-driven insights to refine and optimize marketing strategies.
• Maintain and manage marketing automation and CRM systems to ensure data integrity and campaign efficiency.

What We’re Looking For

• 5+ years of experience in demand generation and/or ABM roles within B2B SaaS, preferably in data, AI, or developer tools.
• Proven track record of designing and executing successful demand generation campaigns that drive measurable pipeline and revenue growth.
• Strong proficiency with marketing automation and CRM systems (e.g., HubSpot).
• Experience with ABM tools and strategies, including account selection, personalized content creation, and engagement tracking.
• Excellent analytical skills with the ability to interpret data and translate insights into actionable strategies.
• Exceptional collaboration and communication skills, with experience working cross-functionally across Sales, Product, and Marketing teams.
• Self-starter with a proactive mindset, capable of thriving in a fast-paced, dynamic environment.

? Why Join Us

• Be at the forefront of a new infrastructure category — and help define it.
• Join a mission-led company backed by top-tier investors and used by global enterprises.
• Work with a small, elite team that blends technical depth with market ambition.
• Competitive salary, meaningful equity, and hybrid flexibility across London and Barcelona.
• Opportunities for professional growth and development in a rapidly scaling startup.
