Our Company

We are Twin Paradox Labs, a small startup with very big aspirations: To remove the technical barriers limiting scientific progress so that humanity’s greatest challenges can be overcome. We are developing hardware to transform quantum and atomic devices from academic experiments into real-world instruments, unlocking entire new fields of research and discovery in applications as varied as greenhouse gas sensing, quantum computing, and space exploration. All of this starts by building precision electronics and optics to manipulate the internal structure of single atoms. That’s what we do.

In the past 8 months we have:

• Launched a prototype laser system on a SpaceX rocket, enabling a quantum gravity sensor for earth observation

• Demonstrated the viability of our technology in the application of greenhouse gas sensing

• Delivered our first product, a robust and compact laser system, to a Government of Canada Defense organization

If you’ve got a “can-do” attitude, want to be constantly learning and trying new things, and want to build the best possible tools to explore and protect our world, we would love to hear from you.

The Role

We are looking for an FPGA Design Engineer to join our team. In this role you will play a vital part in the development of Twin Paradox Labs’ laser systems, focused on both R&D and product development. You will be a leader within our small startup team, taking responsibility for all FPGA development work while working closely with team members in other disciplines to deliver impactful electro-optic products.

You will implement new control algorithms, command structures, and digital signal processing in FPGAs and on ARM cores, and help implement fault tolerance and remote operation to enable laser system use in harsh terrestrial conditions all the way to CubeSats and the ISS.
