  • Comfort operating under limited guidelines and requirements is desirable.
  • Hands-on experience targeting FPGA and Software-Defined Radios, and knowledge of traditional telecommunications and satellite communications systems, is desirable.
  • Demonstrable Android development experience, native or multiplatform, is desirable.
  • Design, development, and maintenance of live micro-service platforms is desirable.
Responsibilities
  • Design new clean-slate products with complete autonomy over architecture.

  • Build quick prototypes to confirm the feasibility of proposed technical approaches and iterate until they meet requirements.
  • Work hands-on in the day-to-day delivery of projects, typically alongside one or two colleagues.
