Let me introduce...

With Sonia, doctors are successful doctors. We create and deploy AI-enhanced solutions that make doctors’ lives easier, patients’ care better, and healthcare systems more efficient. If you’re an intrinsically motivated self-starter who values impactful work, join us in revolutionizing healthcare.

We’re looking for a Head of Marketing (all) to lead our marketing strategy and execution across brand, demand generation, content, and community. This role combines strategic thinking with hands-on implementation—defining our positioning and go-to-market approach while driving campaigns and testing growth channels.

As part of our Management Team, you’ll play a key role in shaping Sonia’s direction and scaling our impact in the healthcare and AI ecosystem.

This role can be performed in a hybrid setup from our offices in Luxembourg or Berlin, or remotely from anywhere in Germany or Luxembourg.

This is what you’ll own

Marketing Strategy & Leadership

• Define and execute Sonia’s marketing strategy in alignment with company goals
• Build, lead, and mentor a high-performing marketing team of 4
• Own the marketing budget and ensure efficient resource allocation

Brand & Positioning

• Strengthen Sonia’s brand and visibility within healthcare and AI communities
• Ensure consistent, compelling messaging across all channels
• Develop and oversee our content strategy (website, social media, campaigns, thought leadership)

Growth & Demand Generation

• Drive customer acquisition through performance marketing, events, and partnerships
• Manage campaigns across digital, social, and offline channels
• Establish a scalable lead generation and nurturing process in collaboration with Sales

Community & Events

• Lead Sonia’s community engagement through newsletters, webinars, and partnerships
• Represent Sonia at key industry events and conferences
• Scale event marketing to engage and inspire customers and prospects

Analytics & KPIs

• Track and report marketing performance metrics (pipeline, CAC, MQLs, brand reach, ROI)
• Use data and experimentation to optimize campaigns and inform strategy

You’ll thrive in this role if you bring

• 6–7 years of marketing experience, including 2–3 years in a leadership role—ideally in B2B SaaS, HealthTech, or AI-driven products
• Proven track record in building and scaling marketing functions in fast-paced environments
• Expertise across performance marketing, content, brand, and events
• Strong command of modern marketing tools and systems, with a focus on scalability and automation
• A compelling storyteller able to position Sonia credibly and confidently in the market
• Strong leadership, communication, and collaboration skills
• Data-driven mindset with experience using analytics to guide decisions
• Fluency in German and English

Why you’ll love working with us

• A leadership role with strategic impact and full ownership of marketing
• The opportunity to shape a fast-growing HealthTech startup backed by top-tier investors
• Close collaboration with the CEO, CTO, and Management Team
• Competitive salary and equity package
• A culture of trust, speed, and personal growth
