Job description

Are you a storyteller and content creator who loves to build stunning visual and written stories (with the help of AI tools) to explain complex technical topics to a wide audience, from investors to engineers and public stakeholders? At Lightium, we're pioneering next-generation photonic integrated circuits (PICs) built on thin-film lithium niobate (TFLN), and we're looking for our first Marketing Lead who owns and drives Lightium's marketing and content creation activities, ranging from branding, visuals, and animation to website and social media management. You will use Claude and other AI tools to accelerate and enhance your production, and you will make sure every claim is correct.

Position Summary

In this role, you’ll join our Sales & Marketing Team, reporting to the CRO, and build the content engine for a young deep tech startup. You will produce and own the written and visual material across our website, LinkedIn, articles, presentations, application notes, customer documents, booth designs, explainer animations, and posters, working with a workflow that you design and document yourself. You work within our established brand system and alongside our Sales team to find where customers need clearer material. R&D reviews your technical content before it goes out. This is a build role: you will define how Lightium produces marketing content, not maintain an existing process.

Key Responsibilities

Website & Digital Presence: Own the website frontend (creation and maintenance) and our social media channels (LinkedIn, YouTube, and others), including content, posting cadence, updates, and SEO, to build inbound interest with the right technical audience. Work with external developers and the backend DevOps team as needed.

AI-Native Content Production: Build and run AI-assisted workflows (for example, Claude projects) that centralize the production of visuals and documents consistent with our brand guidelines across the organization: reports, decks, posters, LinkedIn posts, and more. Deliver at high speed and high quality, and document your prompts, templates, and workflows so colleagues can reuse them.

Creative Design & Animation: Design roll-ups, booth graphics, flyers, datasheets, and social visuals using Canva, the Adobe suite, and AI tools, and produce short explainer animations of our technology. Work closely with the C-suite so that investor and customer decks meet the highest standards.

Technical Accuracy: Run a review loop with R&D for every technical claim, figure, diagram, and animation before publication, because our customers will notice errors. Maintain a source-of-truth sheet of approved specifications and messaging so nothing goes out with an unverified number.

Tradeshows & Conferences: Own the event calendar: select and book events, organize booth materials (artwork, back wall, brochures, samples), and manage booth and team presence at key industry events, working with our Sales colleagues, who own customer relationships on site.

Media & PR: Draftpress releases and own media relationships. Work with our media partners to plan C-level interviews, talks, and podcast appearances.

Corporate & Investor Communications: Support leadership with investor-facing materials, a consistent corporate narrative, and internal communications as the company scales. Publish monthly investor updates and quarterly newsletters, working closely with the C-level team (CFO, CRO, technical and operational leads) for content.

Marketing Operations & Partners: Run the content calendar and track which content produces inbound interest. Own and nurture relationships with external partners: animation studios, graphic designers, copywriters, photographers, freelancers, and print suppliers.

What you’ll bring

Education & Background: Education or training in visual arts (graphics, animation, video, or image editing), or an equivalent portfolio. Copywriting, storytelling, and photography skills are a strong plus.

Experience: 2-5 years in B2B marketing, content, or communications, ideally in deep tech, semiconductors, photonics, or another technical field. Writing for a technical journal is a strong plus. A portfolio of work you have produced matters more than your employer’s name.

Creative & Design Skills: Hands-on ability in Canva and the Adobe Creative Suite (Illustrator, InDesign, Photoshop; motion or video editing is a plus). You can take a roll-up, booth wall, or flyer from brief to print-ready file, and you turn technical content into clean, accurate graphics.

Digital Storytelling: Strong experience telling technical stories on the web and social media: website posts, LinkedIn, YouTube, or X.

AI Fluency: Daily hands-on use of Claude and other generative AI tools for text, image, and animation in real work. You can show us what you made, explain your workflow, say what you check, and say what you throw away.

Judgment: You treat AI output as a draft. You catch wrong numbers, wrong physics, and generic phrasing before anyone else does, and you know when to ask an engineer.

Technical Curiosity: Enough interest in deep tech to learn fast and write credibly. You don't need a technical degree, but you must want to understand what the numbers mean.

Drive: You ship quickly, iterate in the open, and take ownership without waiting to be asked. Most of what you build today didn't exist last quarter.

Collaboration: You extract accurate detail from engineers and leadership and turn it into material that improves how customers experience Lightium.

Language Skills: Fluency in English is required. German or French is a plus.

What We Offer

• A unique opportunity to build Lightium's first marketing & content function from the ground up at a deep tech company with genuine technical differentiation and a clear path to high-volume production
• Competitive compensation and benefits package, including an employee stock option plan (ESOP), reflective of your experience and expertise.
• Become a key player in an early-phase startup and join an impact-driven, diverse team. You will have the unique opportunity to create, grow, and develop your professional skills at a fast pace.

We'd love to hear from you if you're passionate about building new tech from the ground up and thrive in a collaborative and innovative environment. Lightium is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
