Job Description       Position Title: Mechanical Engineer Work Unit: Instrumentation Classification: APS6 Supervisor: Mechanical Engineering Manager In the position the successfully candidate will be acting as a lead mechanical engineer working on the various instrumentation projects that are  ongoing at the Australian Astronomical Observatory. The successful candidate will have a minimum qualification of B.S. in mechanical engineering and eight years of relevant experience.  The candidate must demonstrate a strong ability to work independently on projects with an awareness of cost and schedule constraints.    Experience in designing opto-mechanical assemblies is a must.  The successful candidate must have a flexible, positive attitude and be able to work with other disciplines to ensure the success of the project. As the projects have varying size and scope the candidate must be able to perform in multiple capacities.  The responsibilities can include proposal writing, conceptual design, some project management, estimating, design and analysis, specification writing, assembly and testing. This position requires an individual who is capable of designing and detailing components and assemblies utilizing CAD software.   Individuals with prior experience with Autodesk Inventor will be viewed favorably.  Experience with FEA analysis, in particular ANSYS, will be a plus.   The candidate must demonstrate strong organizational skills, and have the ability to manage projects from concept to finished product.   This position requires individuals to be hands on at times.  Candidates who have prior experience working with piezos and fibre optics will have an advantage.  Candidates who have also demonstrated systems engineering experience in the field of opto-mechanics will also have a strong advantage. In addition, candidates with previous astronomical or space-based instrumentation experience will have an advantage.   back to top
