Head of Marketing - Full remote

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).
