Principal Software Engineer

About the role

Hi, we’re PEXA!

We know you’ll Google us before applying, so let’s keep this brief. PEXA revolutionised the way that property is settled in Australia, turning a paper-based process into a digital one. Our solution is a world-first, with over 500 people across Australia and an expanding international team, we’re helping 20,000+ families into their homes each week.

We’re passionate about solving problems for our customers – always striving to set the standard for how property is bought and sold. Being awarded as one of the best places to work in Australia is a recognition of our culture and commitment to innovation, customers and our community.

We’re growing fast, that is where you come in.

We believe our success in Australia is worth sharing and that our proven technology will advance how the UK buys and sells homes.

Establishing ourselves within the UK in late 2020, we are committed to collaborating with lawyers, conveyancers, lenders, government and the property industry, to set the new standard for both remortgages and buying and selling property.

We're looking for an established Principal Engineer to join our brilliant UK Technology Team. This is a remote first role, but we have offices in Leeds and Thame for collaboration.
