One Group Handling The Complete Aircraft Maintenance Lifecycle
Sigma Aerospace Group recruits, trains, places and deploys the engineers who keep aircraft flying — and maintains the aircraft they work on, on wing and off.
Integrating training, workforce, and MRO solutions creating skilled, licenced aircraft engineers & quality maintenance services for a stronger aviation industry.
Australia’s only fully integrated provider across aircraft maintenance, overhaul, workforce and engineer training.
Sigma Aerospace Group brings together commercial aircraft maintenance, engine overhaul, component overhaul and parts, aviation workforce solutions, and aircraft engineer training under one operating model.
That matters because aircraft downtime, engineer shortages and licence bottlenecks usually do not happen in isolation. Sigma’s structure is built to connect the aircraft, the people and the training to enable us to deliver best-in-class tailored solutions for aircraft operators.
One integrated engineering solution delivering less friction between maintenance, workforce and training.

MRO Services
Direct recruitment, contingent labour and workforce solutions for airlines, MROs and defence operators.
Sigma Aerospace Workforce connects airlines and MROs with aircraft engineers through direct recruitment, contingent workforce and outsourced HR, with support spanning onboarding, payroll, compliance and visa support. Our workforce division also promotes engineer-led recruitment and pre-vetted candidates rather than generic recruiter shortlists.
For international demand, our workforce team also operates OHLA capability to sponsor and place overseas engineers under 482 visas while handling licencing, compliance and workforce management. On the careers side, we position ourself as a faster route for engineers to reach hiring managers and move into roles that fit their aircraft experience, pay and location goals.
Better engineers in the right roles.

Pre-apprentice to Part 66, RPL, type training and workforce-ready engineers.
Sigma Aerospace College covers the training arm of the group, with pre-apprenticeship and industry-readiness programs, apprenticeships and traineeships, Certificate IV and Diploma pathways, CASA Part 66 licensing, exclusion removals, type training, requalification and international licence conversions. Our college offers training for both people starting out,and for aircraft engineers already working in maintenance.
The model is designed to build engineers who can move into real jobs, real fleets and real maintenance environments with a cleaner path through training, licencing and employment.
Aircraft Engineer Training that connects to the hangar, the licence and the job.
