Quantum Product Owner/Tech lead


SpeQtral is looking for highly motivated quantum specialist to join a team of space quantum pioneers at the office in Singapore. We are commercialising quantum communications to prepare the world for the quantum future. Think quantum space lasers, entanglement and military level secure communications. As part of our mission to transform the world’s networks we plan to launch a constellation of satellites to enable world-wide entanglement distribution. The earliest application of this is highly secure delivery of encryption keys to facilitate secret communications.

At SpeQtral, you would work directly together with a team of scientists and engineers to overcome the technical challenges of quantum communication in the real world.


  • Two+ years of working experience in a relevant field, or Master’s degree in physics (with specialization in quantum optics, information or communication, or PhD in quantum optics, information or communication
  • Track record of hardware development and familiarity with full hardware stack (optomechanics, electronics, software).


  • Assist with/oversee the design and development of quantum and optics hardware and software systems and their integration to secure communications networks
  • Join/lead a team of domain and technology experts implementing solutions based on state-of-the-art and/or cutting-edge R&D
  • Work with the business development team and external parties to ensure products are developed to fulfil customer requirements.
  • Effectively present technical content internally as well as to customers or partners
  • Assist with creating commercial and research proposals to support work done at SpeQtral and with partners of SpeQtral
  • Other related functions as assigned

Technical skills:

  • Quantum optics: Experience with optical systems that operate in the single photon regime. Familiarity with measurements and analysis of quantum states, specifically for polarization encoding.
    • Examples: quantum state tomography, polarization entangled photon sources, weak coherent pulsed sources, single photon sources.
  • Free-space optical communications: Experience with transmitting photons over long distances through free space optical channels.
    • Examples: LIDAR, gaussian beam propagation, optical communications.
  • Quantum key distribution: Experience with quantum key distribution systems, free-space or fibre based.

Bonus technical skills – experience in any of the following topics is advantageous

  • Optical design software (Zemax)
  • Quantum key distribution software
  • Electronics engineering
  • Mechanical design
  • Data analysis
  • Quantum communication theory, e.g., QKD protocols
  • Space-to-ground QKD
  • Optical communications
  • Control theory
