Mission / role summary: We are looking for a Marketing & Brand Intern to consolidate Bloomineral’s commercial messaging, visual identity, and client-facing materials as we move from R&D into industrial deployment. You will work directly with our founder Caroline to consolidate Bloomineral’s value proposition across markets (cement, concrete, coatings, etc.), build professional sales assets (decks, one-pagers), and elevate the overall aesthetic and clarity of our communication. This is a hands-on role at the core of the company, ideal for someone who wants to apply marketing skills in a deeptech, industrial B2B environment.

This is a hands-on role in a deeptech B2B environment. Less social media. More real commercial material.

Key Responsibilities

Brand & Messaging

• Help consolidate Bloomineral’s core value propositions across applications

• Translate complex technical concepts into clear commercial narratives

• Ensure consistency of tone, visuals, and messaging across all materials

Commercial Assets

• Build customer decks by product / application / market

• Create one-pagers and technical-commercial sales materials

• Support structuring of client presentations and pilot documentation

• Maintain and organize Bloomineral’s marketing asset library (slides, templates, visuals)

• Help run our social media, website, and newsletter campaign

Visual Execution

• Produce marketing visuals using Powerpoint (Figma / Adobe PS are strong pluses)

• Improve layout, structure, and visual coherence of existing materials

• Support creation of simple visual or video content when relevant

What We’re Looking For

• Currently enrolled in a Master’s program in marketing, communication, design, business, or related field

• Strong interest in B2B marketing and industrial / technical products

• Solid visual sensibility and experience with Powerpoint/ Canva (Figma / Adobe are major advantages)

• Comfortable building structured, professional decks and documents

• Ability to understand technical content and convert it into clear messaging

• Highly organized, detail-oriented, and autonomous

• Fluent in English (French is a plus)

We are looking for someone who has already chosen marketing as a direction, not someone experimenting with it for the first time.

Nice to have

• Experience in climate tech, deeptech, or industrial environments

• Familiarity with tools like Notion, Slack, Figma, basic video editing

• Prior experience creating B2B marketing or sales materials

Why Join Bloomineral

• Work directly with the founding team

• Help shape how a climate deeptech company presents itself

• High ownership, real responsibilities (essentially 1-person marketing team)

• Exposure to real commercial discussions and activity

• Small team, fast learning curve, visible impact

• A culture that values rigor, initiative, and learning by doing

We care more about curiosity, rigor, and drive than about checking every box. If our mission resonates with you but your profile doesn’t match every single line above, apply anyway. We’re building a diverse, thoughtful team and we know great people don’t all look the same on paper. If you’re excited about turning carbon into materials the world can build with, we’d love to hear from you.
