Job description

About FOSSA

At FOSSA, we’re redefining how the world connects. We are a space engineering and telecommunications company with 60+ professionals and 27 satellites launched, building a next-generation constellation for IoT connectivity and dual-use space applications. Headquartered in Madrid with an R&D center in Lisbon, we design, build and operate our own satellites.

Who are we looking for?

We’re looking for an AI & Business Development Internto join our Sales team and help us find and pursue new opportunities with public and government customers, in Spain and abroad.

This is not a traditional sales internship. We want someone who uses AI as a core part of their work: building workflows to screen tenders faster, research institutions, qualify opportunities and prepare outreach at scale. You’ll have the freedom to experiment with the latest AI tools and turn manual processes into smarter, automated ones.

Responsibilities:

• Screening national and international public tenders and funding calls, using AI tools to filter, summarise and prioritise them.
• Technical pre-assessment of opportunities and their fit with FOSSA’s capabilities.
• Researching government and defence institutions and supporting cold outreach.
• Building and improving AI-assisted workflows for lead research, tender monitoring and proposal drafting.
• Keeping the opportunity pipeline and CRM up to date.
• Supporting the preparation of proposals and commercial presentations.

Profile:

• Student or recent graduate in Engineering or a technical field.
• Hands-on experience using AI tools (LLMs, assistants, automation platforms) in your studies or projects.
• Interest in sales and the business side of technology.
• Fluent English and Spanish.
• Organised, proactive and confident when contacting new people.

Preferably:

• Basic scripting skills (Python or similar) or experience with no-code automation tools.
• Interest in the space and defence sectors.
• Knowledge of public procurement (TED, PLACSP, ESA, EDF).
• Experience with CRM tools.
• Additional languages.

Why FOSSA?

• Learn how institutional and defence business is built in the space industry.
• Shape how a fast-growing company uses AI in its commercial processes.
• Work alongside engineers and sales professionals in a fast-paced environment.
• Flexible working arrangements with a strong focus on work-life balance.

FOSSA believes in equal opportunities; all applications will be considered and no discrimination for any reason will be tolerated.

Location: Las Rozas, Madrid.

Paid Internship. The candidate must be able to subscribe an agreement between their educational institution and FOSSA.
