ABOUT ALEXERGY
Senior engineering judgement.
Grounded in plant reality.
Alexergy Engineering is an independent Australian engineering consultancy helping industrial and energy clients make safer, clearer technical decisions from early design through to operating-plant challenges.

THE PRINCIPAL ENGINEER
You work directly
with Alex.
Alex Mashego is a chemical engineer with more than 20 years of experience spanning plant operations, process design, commissioning, process safety, engineering management and technical leadership.
His career has moved from hands-on operating environments to senior and principal engineering roles. That perspective keeps the work technically rigorous, commercially aware and grounded in how plants and project teams actually operate.
Every engagement is scoped around the problem, the evidence available and the decision your team needs to make.

HOW WE APPROACH THE WORK
Plant context first
Understand the process, the people involved and the conditions under which equipment and safeguards must work.
Transparent reasoning
Keep inputs, assumptions, uncertainties and limitations visible so the work can be reviewed and trusted.
A usable handover
Provide clear findings, documented recommendations and a practical route to the next decision.
WHEN TO INVOLVE ALEXERGY
Bring us in when making the right decision is important.
Shape the basis
Define the technical problem, compare options and establish a defensible design basis.
Test the assumptions
Review designs, vendor information, safeguards and risk decisions before commitments are made.
Resolve plant issues
Investigate constraints, support modifications and turn findings into practical next actions.
LET’S TALK
A clear next step starts with a conversation.
Tell us about your plant, project or technical challenge. We’ll help define the question and the engineering support it needs.
