Basel Swim

Basel City Centre, Switzerland - Yearly Rhine Swim Event - Home to Numfum GmbH

Numfum’s core team have been developing software products together since the 1990s. They have designed and developed top notch, award winning software in computer game and white collar sectors over the past 3 decades. Indeed... we might be small, but we’ve already empowered our clients to realise millions of dollars in sales revenues.


We are looking for the right person to develop a script VM and bytecode compiler which will integrate with our existing 3D graphics engine and planned (GL-based) 2D UI. If you think you can squeeze a custom JavaScript implementation into 4KLOC, then this job is most certainly up your street.

The long-term goal here, is a completely script-driven game engine, replete with interactive shell and step debugger, tied into a custom IntelliJ-based IDE. We already have a proof-of-concept stack-based VM with DBGP remote debugging, but are willing to allow some autonomy given the right candidate.


Do you enjoy the cut and thrust of a charged office environment? Do you relish the thrill of building a reputation, and climbing up the ranks? Are you the sort of person who has something to prove? If any of this resonates, then please don’t apply. We are only looking for talented, easy going people, who would like to work in a pleasant environment alongside some highly skilled industry veterans.

The job is full time and pays a good salary. All statutory requirements such as pension and accidental health cover are complied with. Where appropriate, we’ll also discuss a relocation allowance.

We welcome applications from citizens in the EEA / EU-28.


  • Expert level C++
  • Demonstrable VM and compiler projects
  • Deep multi-platform knowledge
  • Day to day office language is English

Bonus Points

  • Games industry experience
  • Emscripten / WebAssembly / NaCl
  • Game engine development
  • Experience of small, constrained devices
  • Java and IDE plug-in experience
  • Conversational German and / or French
