Today, most countries across the world lack access to the internet and with that, the resources to do business, exchange ideas and learn. 

Severe bottlenecks at all levels, what we call the Global Internet Distribution Challenge, has led to more than 50% of the world left unconnected entirely OR connected but with extremely poor access to the Internet. The outcome is that large swaths of the global population are hence prevented from accessing life-changing and economy-driving tools and services offered by the Internet.

What if you could really change the future?


We are building a space laser network to deliver the future of Internet Distribution worldwide. This will be the fastest way to bring the rest of the world up on the bandwidth and connectivity curve. Right now, we are using the same technology to provide a rapidly deployable, affordable, low cost and high speed Last Mile Connectivity solution, CENTAURI, which speeds up adoption of 4G and 5G globally, specially dense residential areas during COVID-19 period which require urgent bandwidth upgrades.

Join our team if you want to define the rules of how our civilisation communicates!


Senior Space Optics Monostatic Engineer



Responsible for the optical system architecture design of the space laser communication device. 

Tasks includes:

  1. Designing advanced diffraction limited telescopes for space and ground applications, including STOP analysis and Athermal Optics designs
  2. Selection of materials for optical systems to work efficiently in space environments
  3. Simulation of optical systems to validated performance in various environments including vacuum and high thermal gradients
  4. Designing bonding and calibration mechanisms for assembly of optical system within design tolerances
  5. Design testing and qualification mechanisms to assemble and validate the optical system
  6. Propose and conduct experiments to test the various optical components in the system.
  7. Identity critical system components and explore the operating limitations.
  8. Improve the overall efficiency of the system.
