At Opti-Num, we embrace diversity.

We understand that employing leading minds with the talent and expertise to deliver world-class solutions is just the start – we have to follow up by nurturing the environment in which they can thrive.

And that is what we do - allowing our team the freedom to think outside the box and find innovative solutions to some of the greatest challenges facing business today.  

Why work with us?


Cross industry exposure

Consult with, get advice from, and share with colleagues from a wide range of industries, including telecommunications, mining, process engineering, aerospace and defence, automotive, property, and financial industries. We have a culture that encourages knowledge transfer through project shares and code and design reviews at all levels.


Flexible hybrid working conditions

We support working remotely, but our well-equipped offices with a great atmosphere are available for those days when you wake up in the mood for the office environment where in-person collaboration is much more productive. You can find strong coffee, and sweet carbonated drinks there too, in case you need that extra kick!


Financial well being

We believe in making good decisions, for our clients, and for our staff. So in support of this, Opti-Num makes contributions towards your provident fund and life cover.


Mentorship and growth

We have a strong culture of growth. We like to push people to achieve their potential. A strong part of this is mentorship from multiple layers of seniority in the company. Our staff receive mentorship and guidance from seniors and executives, and have the opportunity to mentor others on the team.


Endless Learning Opportunities

Your core responsibility supporting Applications Engineering will inherently require continuous learning as you engage with new clients and technologies. Additionally, we have coding dojos, a data science club, and internal training courses, as well as funding for external courses and further studies.


Great culture

Happiness and work-life balance is important to us. We even give you an extra day off in your birthday month!

We love having the occasional team outing to have fun as a team – some favourites have been racing go-carts, riding quad bikes, walking around a park or simply having a good lunch together.
