Working Student / Intern (GTM & Marketing) (m/w/d)

Job description

At Celdon, we're building AI-powered workflow automation platform for enterprise finance teams. We aim to help accountants, financial analysts, tax advisors and CFOs reduce their manual work.
We're an early-stage startup, moving fast, and focused on bringing Noah to market. Now we're building our GTM engine from the ground up – and we're looking for a sharp working student to help us grow.
The Role
This isn't a sideline seat. You'll work directly with the founding team across the full GTM spectrum – from content and SEO to customer success touchpoints and outbound. You'll own real projects, learn by doing, and help shape how our product shows up in the market.
We are hiring for this position as either an Intern or a Working Student, depending on your availability.
Working Student hours: 16–20 hours/week during semester
Internship possible based on your individual and university requirements
Start: As soon as possible
Tasks
In your role, you'll work directly with the founding team to build our GTM engine and marketing and product content. You will:
Content & SEO

Research, write, and publish content in German and English across our website, blog, and social channels
Support SEO strategy: keyword research, on-page optimization, and technical fixes
Help develop case studies, product explainers, such as videos and guides, and thought leadership content targeted at finance teams
Update content regularly and spot new topic opportunities based on trends and competitor activity

Customer Success & Community

Assist in maintaining customer documentation, FAQs, and help content
Monitor feedback channels and relay insights to product and marketing
Support beta customers with feedback and experience on our platform

CRM & GTM Operations

Keep our CRM clean and up to date
Track GTM KPIs, support reporting, and help us stay organized across campaigns and follow-ups
Track performance in tools like HubSpot or similar – flags, dashboards, basic reporting
Spot gaps and proactively suggest improvements – we love that

Learn by Doing

Get hands-on experience in B2B GTM, AI-driven products, content marketing, and how early-stage companies build their growth engine.

Requirements
We care more about curiosity and drive than a polished resume. You'll thrive here if you:

Are passionate about AI topics and current trends
Can translate ideas into stories that catch attention of enterprise customers
Fluent German and English (C1+)
Are currently enrolled at a university in Germany, available ~16–20h/week
Are comfortable writing clearly in both German and English — for technical and non-technical audiences
Like figuring things out, trying tools, and learning fast
Have strong attention to detail and are comfortable with numbers

Bonus if you've worked with content tools (Storyblok), HubSpot, SEO tools, design tools (Figma, Canva, Photoshop, etc.) or video tools (Loom, ElevenLabs, Vimeo) – even just for personal projects.
Benefits

Direct collaboration with the founders and our small professional team - flat hierarchies and experience sharing
Early ownership and fast decision-making – your work ships and matters
Exposure to the full GTM playbook: content, SEO, CRM, customer success, and growth
Hands-on experience building an AI product from early stage to scale
Flexibility and autonomy in how you work – the position is mostly remote

Join our team to build a market strategy for a product redefining how finance teams work at one of the most exciting moments in AI.
We hire for drive and curiosity – everything else is secondary. All applicants are welcome.
