Chief of Staff (to-be COO) // Magic Sandbox

July 8, 2019

We’re building the world’s most complex browser interface, an all-new learning medium.

Books & documentation have evolved into video tutorials the past decade. We believe we’re at the cusp of a fundamentally new learning era that leverages the latest technologies which will finally narrow the gap between education & work. Developers used to learn by reading, then by watching and are now finally able to learn by doing. Because the platform we’re building is pushing the limits of what is technically possible – we are looking for exceptional people who’ve mastered their craft and love challenging the status quo.

Learn more about the MSB Mission & Platform



Build & Run Operations so MSB can double every quarter.

MSB is the most deep-tech education platform in Europe. The platform is growing rapidly and up-skilling thousands of engineers per day from all over the world. This is the time we need to build out our organisation around our product-heavy team. What was hacked together before now requires a v1 process.

We will grow from a team of 7 today to a team of 20 next year. This is a very dynamic & operational role that requires analytical and problem-solving skills in combination with a strong desire to get things through the finish line.

Example projects you’ll drive:

  • Act as a liaison between the CEO, lawyers and stakeholders while we set up a new entity in a new country…
  • Triage and lead communications with high-level partners/clients/candidates (VPs at F500s)…
  • Research, structure and complete investor decks in prep of a new financing round…
  • Build out processes for customer on-boarding, hiring, product feedback etc…
  • Set up a customer support process, hire first customer success manager…
  • Help build out a financial model to forecast burn / projections / P&L etc…
  • Drive the streamlining of our accounting process, manage stakeholders…
  • Help drive marketing materials, manage press, support Head of Design…
  • Drive the search for a new office, scout locations, negotiate…

You’ll be the operational spider that enables MSB to endure hyper-growth without breaking.

  • We’re not looking for an exact profile other than you’ve done some impressive things before
  • Could be that you excelled during your studies, or excelled in sports, science or in the liberal arts
  • An ex-consulting background (MBB) in combination with experience at a scale-up would be a plus
  • Bottom line is you’re smart, know how to triage problems with limited resources and get things done
  • Great role for ex PMs, consultants, finance talents that want to join a scale-up to grow into a COO role.
  • You’re very efficient working on a Mac and are not afraid to learn (Gsuite / Excel / Keynote / Zapier etc.)
  • We’re a very international team so if you’ve spent some time adventuring around the world that’s a plus :)
  • You’re fluent in English and ideally also in German


MSB was founded by Mislav Stipetic (CTO) and Jord van den Hooff (CEO).

Mislav hails from the East of Croatia and later moved to Zagreb where he studied CS. Always hacking projects on the side, one of them landed him a speaker slot at the EuroPython in Berlin.

His most recent role was at Infarm where he was a Tech Lead running IoT. In 2018 he got accepted into EF which is where he met Jord…

Jord grew up around Amsterdam and moved to China when he was 19. He ended up studying Chinese and worked across China (Shenzhen, Chengdu & Shanghai) for 10 years. He co-founded Taxi-Book (a translation tool) in 2008, Jellyfish (a nightclub) in 2010 and Artifesto (a web-to-print e-commerce in 2011 – RIP). After that he joined agencies Razorfish & Publicis in Shanghai where led design teams as UX Director. In 2017 he moved to Nairobi where he joined the Lori team to help set up product. After a short stint in Africa he joined BCG DV in Berlin as a senior PM. In 2018 he got into EF as well and started discussing the state of EdTech with Mislav…
