Technical Founder's Associate Intern (f/m/x)

Become part of Tanso and decarbonise industries with us.

To develop a brand-new software module from scratch - from the first product decision to go-to-market, marketing rollout, and sales motion, we are looking for a Founder's Associate Intern (f/m/x).

This role sits at the centre of one of the most demanding and exciting things a startup can do: launching something entirely new.

We're not looking for someone to support a team. We're looking for someone to build with us.

Key responsibilities

• Drive the zero-to-one development of a new software module alongside the product and engineering team - from early concept to shipped feature.
• Own the go-to-market strategy: define positioning, shape the narrative, and coordinate the marketing and sales launch end-to-end.
• Build and manage key partnerships and business development initiatives that support the module's market entry.
• Identify and close execution gaps across product, marketing, and sales - whatever needs to happen to move the launch forward.
• Contribute to operational processes and internal tooling that help Tanso scale as we grow.

Your profile

• You think like a founder: you're proactive, comfortable with ambiguity, and take ownership without being asked.
• Practical knowledge in sustainability that lets you hold your own in product discussions.
• Comfortable working in technical environments: familiar with Git/GitHub, dev tooling, and close collaboration with engineering teams.
• Experience or strong interest in go-to-market, business development, or product management.
• Fluency in German & English (C1 level).

What we offer

• Hybrid working model that combines the benefits of onsite collaboration with the flexibility needed.
• Sponsored access to EGYM Wellpass to prioritize your wellbeing with thousands of options.
• Exclusive discounts that help you save on a wide range of everyday brands, services, and experiences.

Why Tanso?

• Directly influence how companies understand, act upon and report on sustainability.
• Lead initiatives that matter, in projects where innovation meets purpose.
• Drive ideas forward and take responsibility to make a difference.

Our team

We're a diverse group of people, and that diversity is what makes us great. We bring unique perspectives to everything we do and are always eager to learn from each other. We work in cross-functional teams to tackle ambitious challenges, actively seek feedback and be the best versions of ourselves.
