SKA-Mid Dish Structure Servo Technician
At the SKAO we are coordinating a global effort to deliver one of the largest science facilities on the planet. The SKAO telescopes will be next-generation instruments that will help to answer key questions in astrophysics, drive technological innovation and support human capital development.
More than a dozen partner countries and over a thousand scientists and engineers around the world are already on board, making the SKA project an international collaboration like no other, and one of the most ambitious science and engineering endeavours of the 21st century.
Headquartered in the UK, with telescope sites in Australia and South Africa, the SKAO will be one observatory operating two telescopes, an endeavour spanning three continents. Multinational by design, in early 2021 the SKAO became an intergovernmental organisation, one of only a select handful of science infrastructures to do so worldwide.
Construction activities for the SKAO's telescopes in Australia and South Africa started in 2021, along with a ramping up of SKAO staff in both countries. It is expected that the transition from the Construction Phase to the Operations Phase will happen around 2028.
SKAO Operations in South Africa will be conducted in partnership with the South African Radio Astronomy Observatory (SARAO). SKAO Operations in Australia will be conducted in partnership with the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The Observatory will also partner closely with a global network of SKA Regional Centres through which astronomers will access science data products and a suite of tools and resources to further analyse the SKA telescopes' data.

The SKA Observatory offers a competitive salary and a generous pension and benefits package. As an employee of an intergovernmental organisation, an appointee who is not a national of the country in which the role is based may be subject to personal Privileges and Immunities.
SKA-Mid Dish Structure Servo Technician
An exciting opportunity for a Servo Technician with experience in precision motion control of electro-mechanical servo systems to join an international, multicultural organisation and support the construction of the largest radio telescope on the planet.
The Role
The Servo Technician will support the Lead Servo Technician to integrate, commission and test the Dish Structure servo system in order to deliver SKA Dishes to the Observatory for the SKA-Mid Telescope. the SKA-Mid Dish Construction Site (located in the Meerkat National Park, approximately 90km from Carnarvon).
The successful candidate will receive on-the-job training from the Dish Contractor (CETC54). The servo system features a Bosch Rexroth motion control system with three independent axes used for steering the telescope (azimuth and elevation) and the feed indexer.
This role will be reporting to the SKA-Mid Dish Site Construction Manager.
This role will be a 2-year fixed term appointment and will be based in Carnarvon, Northern Cape, South Africa for the duration of the contract.
SKAO is committed to providing an inclusive and flexible working environment, meeting the requests of our Colleagues whilst also fulfilling the needs and objectives of the Observatory.
There may be occasions where this role requires the post holder to work across different time zones and, in line with SKAO policy, flexible working hours will be supported in agreement with the line manager.
