World in my hands

Wireless Research Engineer

Closing date: 30 June 2018

AmmbrTech Group designs, develops and manufactures a range of hardware and software within the general area of decentralised systems. With operations in Europe, Asia, the United States and Africa, we embrace diverse and entrepreneurial minded individuals with a desire to effect positive change in society through technology.

Ammbr Research Labs (ARL) is a research body that supports AmmbrTech product development and carries out research thought leadership and conceptualization by identifying or generating underpinning academic work in the field of decentralized systems and interpretation of key learning and impact of that work to others in the company. ARL will test new algorithms, architectures and concepts through modelling, simulation, prototyping and testbeds and disseminate these through research papers and white papers in order to receive peer review from experts in the field. ARL will also test products, or components of products, through access to domain experts, or facilities such as emulators, simulations or test beds to validate and expose flaws and capture key learning for the product development teams.

The Cape Town ARL office will be carrying out research on TV white space, WiFi and advanced mesh technology and will also develop rapid prototypes in both lab and outdoor test bed environments in partnership with the international team carrying our product development of the Ammbr router hardware and firmware. In the future other radio technologies such as Small cell and LoraWAN will also be explored. We have a vacancy for a Wireless Research Engineer.

The purpose of this job is to carry out research in the area of wireless protocol engineering and develop rapid prototypes at the physical or data link layer for these offerings and is well suited to an individual who enjoys intellectually challenging and rewarding work. The initial focus will be on research on TV White space radios that will be integrated into the Ammbr router product. We value bright, curious, growth oriented individuals who enjoy pushing the boundaries of what’s possible – often testing ideas they have in their own time.

Key responsibilities:

The incumbent will be required to:

  • Work in a team with other developers and researchers locally and internationallyto carry out research in the area of wireless communication protocols such as TVWhite Space and WiFi and LoraWan.
  • Develop rapid prototypes that integrate radio modules or develop softwaredefined radio components (written for an FPGA or an environment likeGnuRadio) for the Ammbr platform.
  • Responsible for MAC layer modifications to the protocol where needed e.g.TVWS adapted to work in mesh mode.
  • Responsible for Dynamic Spectrum Access aspects of the work such as using spectrum sensing and geo-location spectrum databases to allocate optimal channels.
  • Translate protocol specifications and designs into software or gateware for a cognitive radio system, and develop rapid prototype systems that will be deployed in the field.

Qualifications, skills and experience:

  • A Bachelor’s degree in a relevant and related field (e.g. computer engineering, electronic engineering) and relevant practical experience.
  • A postgraduate degree in electronic engineering or computer engineering would be advantageous especially if the thesis was in a field related to software defined radios / dynamic spectrum access / TV White space.
  • At least five years of design and development experience in embedded programming using C/C+, Embedded MATLAB and programming FGPAs or cognitive radios.
  • Experience with MATLAB, GnuRadio and FPGA development tools would be advantageous.
  • Familiarity with wireless digital communication: Digital Modulation and demodulation, and filters etc.
  • Familiarity with Radio propagation
  • Experience with embedded operating systems such as OpenWRT or any otherLinux derivative designed for embedded systems
  • Ability to work on complex projects with uncertain or evolving requirements.
  • Ability to find creative technical solutions to problems and think outside the box.

Applicants must attach the following documents:

  • Certified copies of academic results (including the latest ones) or transcript(s).
  • Certified copies of tertiary qualifications.
  • Links to websites / videos for any projects they have been involved in

Package:

Highly competitive salary with the addition of equity and tokens

Network Research Engineer

In the future other radio technologies such as Small cell and LoraWAN will also be explored. We have a vacancy for a Network Research Engineer.

The purpose of this job is to carry out network research at an algorithm, mathematical or simulation-based level and quickly develop code in a prototype router to test these ideas in an indoor or outdoor test bed. Most of the initial work will be focussed on wireless mesh networks – specifically areas like routing metrics, channel selection, and pricing integration. The prototype code will mostly be developed using the OpenWRT-based Linux operating system on the router platform and server platforms that connect to these devices and is well suited to an individual who enjoys intellectually challenging and rewarding work. We value bright, curious, growth oriented individuals who enjoy pushing the boundaries of what’s possible – often testing ideas they have in their own time.

Key responsibilities:

The incumbent will be required to:

  • Work in a team with other researchers and developers locally and internationally
    to carry out research and develop rapid prototypes of features required in future versions of the Ammbr router product.
  • Write embedded code for an algorithm that implements a feature such as a new routing metric or distributed sensing on OpenWRT or writing server code to process data from multiple routers.
  • Carry out extensive testing of new prototypes or early product versions in testbeds and trial networks and provide feedback to product development and research teams.
  • There is a significant amount of experimentation required for this role where you will be required to think quickly and creatively.

Qualifications, skills and experience:

  • A Bachelor’s degree in a relevant and related field (e.g. computer engineering, electronic engineering) and relevant practical experience.
  • A postgraduate degree in electronic engineering or computer engineering would be advantageous especially if the thesis was in a field related to network systems.
