The Radio Frequency Interference and Electromagnetic Compatibility (RFI & EMC) engineer for the Square Kilometre Array Low Telescope (SKA‐Low) will form a critical link between the SKA Observatory (SKAO) headquarters (HQ) and the SKA‐Low telescope project in Western Australia with regards to RFI & EMC management and control during the construction and operations phases. The engineer will form part of the SKA‐Low Site Management Team to address the management of RFI through the guidance of SKAO HQ.

Furthermore, the successful applicant will lead a team of RFI engineers and technicians at the SKA Low site in Australia to eventually achieve the full scope of work below and need to initiate work in each of the critical areas before the remainder of the team is on board. Initially, the focus of the position will be on the construction phase, compliance of equipment being installed at the site, and activities on the site to ensure the overall compliance of the SKA to its own and the MRO’s RFI/EMC standards. Over time, this will transition to the ongoing monitoring, analysis and control during the operations phase.

In addition, the position will play a key role, contributing to the coordination and management of RFI & EMC matters within the SKA‐Low project. This will include developing new management, engineering, and broader communication processes for the SKA‐Low telescope and implementing existing SKAO policies and procedures. Also, the successful candidate will deploy the RFI monitoring architecture design and will be responsible for actively monitoring RFI at the SKA site on the MRO, analysing results and following up as required on results.

The position will promote teamwork between SKAO HQ, SKA‐Low and national stakeholders (CSIRO) in resolving RFI/EMC issues and motivating, coaching and developing people in the team to build functional skills in dealing with RFI & EMC related requirements.

The position will form part of the wider SKAO RFI group, representing the Observatory at national and international meetings and conferences, detailing SKA‐Low activities related to RFI & EMC related SKA‐Low project activities. In addition, at the national level, they will contribute to the SKA’s RFI site policies definition and implementation.

The position will interact with a wide range of stakeholders, especially the Commonwealth Scientific and Industrial Research Organisation (CSIRO) MRO Site Entity team and its RFI Compliance Leader, working collaboratively to help ensure the long‐term quality of the MRO site.

Consideration may be given to performing this role on either a full-time or job share basis. Please indicate your preference in your application.

Duties and Key Result Areas
  • The RFI & EMC Engineer (SKA‐Low) will have regular meetings with SKAO HQ RFI Working Group to present the SKA‐Low RFI & EMC related issues, environments and compliance management:
    • Weekly presentations and regular written reporting to SKAO HQ.
  • Work closely with the CSIRO RFI Compliance Leader to ensure SKA compliance to the MRO RFI/EMC Standard.
  • RFI Qualification of SKA‐Low and ancillary hardware/equipment:
  • The position will oversee the RFI qualification of equipment intended for the SKA‐Low.

Some of the duties will include:

  • Review of RFI Qualification Test Procedure documents and Qualification Test Results reports.
  • Assisting SKAO and external stakeholders in identifying suitable test facilities to perform RFI Qualification to SKA RFI/EMC Standard requirements.
  • Assisting in the identification of RFI mitigation measures and solutions. Provide specialist advice on specific RFI & EMC issues as required.

RFI Management, Control and Policies for SKA‐Low telescope site:

  • Work collaboratively with colleagues both in SKAO and external stakeholders to achieve SKA compliance with SKAO and the MRO’s RFI/EMC Standard requirements for activities and equipment deployed to the SKA site.
  • Assess and “own” SKA‐LOW project-related RFI & EMC risk issues.
  • Articulate and explain RFI & EMC constraints to various stakeholders at all levels.

RFI Environment and Monitoring for SKA‐Low:

  • Lead the characterisation of the RFI environment for SKA‐Low, including deploying RFI monitoring hardware and software systems. This includes measurements and data analysis using both fixed and mobile monitoring infrastructure and characterising and identifying RFI emitters.
  • If required, the RFI & EMC Engineer must perform in‐situ measurements in the field to identify and characterise RFI culprits using a variety of antennas, current probes and RF receivers. These include both time domain, as well as real-time and sweeping spectrum analysers.
  • Provide input and use‐cases to the SKA‐Low Signal Chain and Science Data Processing domain specialists and teams to characterise the impact of RFI on the signal chain.
  • Communicate openly, effectively, and respectfully with all staff, clients and suppliers in the interests of good business practise, collaboration and enhancement of SKAO and CSIRO’s reputation.
  • Work collaboratively as part of a professional regionally and internationally dispersed team.
  • Adhere to the spirit and practice of both SKAO and CSIRO’s Values and the Code of Conduct, Health, Safety and Environment procedures and policy, Diversity initiatives and Zero Harm goals.
  • Other duties as directed.
