Job Description
Let’s introduce ourselves
We’re a venture-scaler powered by CommBank. That means we build, buy, and invest in startups that could benefit the bank’s 15 million customers and beyond.
Because of what we do, we’re really neither corporate, nor startup – instead we’re happily navigating the space between both worlds. We're close enough to benefit from the bank’s strategy, scale and stability, but separate enough that we have the autonomy to try new things. To be a sandbox for change
What it’s like to work here
We’re a community of galvanisers, thinkers, and doers. We have a big, bold vision, which so far no-one has nailed (including us). That excites, rather than deters, us.
We never lose sight of the impact we can have on people’s lives, and the role that each of us plays in shaping the bank of the future. We don’t take ourselves too seriously and make time to connect to celebrate and grow our people.
At x15, we’re guided by three values: Care, courage, and commitment. And what does that mean? We’re aware, attuned, and always act to help our people and our customers. We’re more than just job titles and we don’t hide the human stuff. We lead with grit and grace and do what's right – even if it's hard. And, whatever happens, we always find a way .
