About Us: Silex is an award-winning and VC-backed LegalTech startup based at EPFL Innovation Park in Lausanne, building the next-generation AI-powered legal platform. Our ambition is to create the infrastructure layer for legal intelligence, the foundation on which legal professionals will search, reason, draft and manage knowledge.
Job Description: We are looking for a rare kind of Head of Marketing.
Not someone who wants to manage marketing from a distance, but someone who wants to build something meaningful from the ground up.
Someone who understands that in an early-stage startup, marketing is not a department, it is a growth engine, a narrative, and a strategic weapon. Someone who rolls up their sleeves, takes ownership, and makes things happen.
Key Responsibilities:
· Own and define the overall marketing strategy
· Build and execute a powerful go-to-market strategy to accelerate customer acquisition.
· Develop a strong category positioning and narrative at the intersection of law and AI.
· Drive demand generation and growth, from early traction to scalable growth systems.
· Lead product marketing, ensuring clear positioning, messaging, and market education.
· Build and execute a content and thought leadership strategy to position the company as a leading voice in LegalTech and AI.
· Design and implement high-impact marketing campaigns across multiple channels.
· Collaborate closely with founders, sales, and product teams to align marketing with company strategy.
· Manage and coordinate external partners (design, CRM, content, etc.).
· Build and scale the marketing function and team over time.
Who You Are:
· You have experience in B2B SaaS startups, ideally in early-stage or high-growth environments.
· You combine strategic thinking with strong execution skills.
· Creative and proactive, with a “can-do” mindset and a willingness to take initiative.
· You have an owner mentality and take full responsibility for outcomes.
· You are extremely hands-on and comfortable operating in fast-moving startup environments.
· You thrive in building things from scratch rather than managing established structures.
· You know how to translate complex products into clear, compelling market narratives.
· You are comfortable working with external partners and multidisciplinary teams.
· You are curious, ambitious, and motivated by building something meaningful and impactful.
· You want to help build a company that can define a new category in LegalTech.
· Strong written and verbal communication skills in French, English and German.
· Why Join Us:
· Join at an early stage and play a key role in shaping the company’s trajectory.
· Own the marketing function and build it from the ground up.
· Flexible setup and remote work
· Work directly with founders and influence core strategic decisions.
· Build something meaningful: help reshape how legal knowledge is accessed and used.
· Be part of a company with strong technological foundations and ambitious growth plans.
· Help build a category-defining LegalTech platform in Europe and beyond.
Start date: As soon as possible (ASAP).
