Mechanical Engineer — Directed Energy Systems

Electro Optic Systems; Canberra; On-site; AUD 90,000 - 130,000; Full time

Job summary

Electro Optic Systems in Canberra is seeking two Mechanical Engineers to advance our directed energy programs. You will take designs from concept through analysis and detailed drawing to field-ready systems, with emphasis on precision opto‑mechanical structures and thermal management.

Each role spends time in the field, tackling beam director assemblies, cooling loops, platform integration, and equipment maintenance, with hands-on work in the workshop and on trial sites.

Qualifications

• Degree in mechanical, mechatronic or aerospace engineering.
• Minimum 4 years in mechanical design for demanding applications.
• Advanced 3D CAD proficiency in SolidWorks, Creo, NX or Inventor.
• Demonstrated analysis capability across structural, modal or thermal cases.
• Practical understanding of machining, sheet metal, welding and surface treatment processes and their cost drivers.
• Experience taking a design from concept through prototype build to test.
• Hands-on approach, comfortable in the workshop and on the range.
• Willingness to travel to the test range and trial sites regularly, including periods of out-of-hours work.

Responsibilities

• Design precision opto‑mechanical assemblies including beam director structures, mirror mounts, gimbal interfaces and optical bench layouts.
• Design thermal management for high energy laser subsystems, including liquid cooling loops, chillers, heat exchangers, pumps and coolant selection.
• Produce detailed 3D models and manufacturing drawings to AS 1100 with correct geometric dimensioning and tolerancing, tolerance stacks and fits.
• Perform structural, modal, thermal and fluid analysis to verify stiffness, alignment stability, cooling capacity and transport survivability.
• Design the platform integration, including layout, mounting, access, serviceability, mass properties and lifting provisions for containerised and vehicle mounted configurations.
• Select materials, finishes, fasteners and coolants suited to alignment retention, corrosion resistance and the Australian field environment.
• Work with suppliers and the internal workshop on manufacturability, cost and lead time, and support build, alignment, integration, test and field maintenance.
• Maintain drawing sets, bills of material and configuration records under engineering change control, and contribute to design reviews and trade studies.
