Job description

We’re partnering with an early-stage European defence-tech company developing autonomous robotic systems for real-world operational environments.

The team is building next-generation autonomy technology, with a current focus on aerial robotics and counter-drone systems. Their work combines advanced algorithms, robotics, perception, control and physical hardware to create autonomous systems capable of operating reliably in complex and dynamic environments.

We are looking for a Founders' Associate.

The role

Be the founders' right hand, across both the practical and the strategic. One day you keep four founders (CEO, CTO, CPO, CSO) organised and unblocked; the next you help them step back and focus as we scale from a small team toward 50+. It takes real detail-obsession and process discipline — you're the person who brings order to a fast-moving company and makes it run smoothly, with nothing falling through the cracks. It's a role that grows with you: hands-on operations and executive support now, Chief of Staff as the company scales.

What you'll do

• - Keep the founders organised and their time protected — calendars, travel, meetings, inbox and prep, with nothing dropped.
• - Design, document and run the processes and systems the team relies on — bringing repeatable structure and operational rigour to a fast-moving company.
• - Run the operating rhythm — leadership meetings, goals / OKRs, reporting cadence, and board and investor prep.
• - Drive the founders' highest-priority cross-functional projects end-to-end — fundraising support, hiring, operations — owning the details through to done.
• - Turn strategy into execution: chase blockers, keep the org aligned, and follow through where others drop the ball.
• - Prepare board decks, investor updates and internal communications to a high standard.

What you'll bring

• - Exceptional attention to detail and a process / systems mindset — you build repeatable processes, document them, and catch the things others miss.
• - 3–6 years in a high-tempo environment — executive support to founders, startup operations, chief-of-staff, or top-tier consulting (we're flexible on level for the right person).
• - Someone who operates at both the detail and the strategic level — equally happy fixing a calendar clash and structuring a board update.
• - Strong organisation, discretion and ownership; calm and resourceful in ambiguity and at speed.
• - Strong written and verbal communication; fluent Spanish and English.

Bonus points

• - Deep-tech or defense exposure; fundraising / board support; recruiting or people-ops; experience building operating systems and SOPs from scratch.

What we offer

• - Direct access to the founders and real ownership on a small, senior team building something that matters.
• - A front-row seat as we scale, and Made-in-Europe impact.
