Senior iOS Engineer

Bilue is a digital consultancy that designs and builds smart, user-friendly technology for some of Australia’s most well-known businesses. From mobile apps to beautifully designed web platforms and digital experiences, we create solutions that drive impact and deliver exceptional customer outcomes.

Our culture is people-first and purpose-driven. We’re a down-to-earth, values-led team with offices in Sydney and Melbourne, and a growing presence in Manila. We genuinely enjoy working together, whether we’re solving tough tech problems, brainstorming creative solutions, or grabbing a coffee between meetings. Curiosity is encouraged. Collaboration is second nature.

We value excellence, not ego, and back each other to do great work without micromanagement. With low politics and high trust, it’s a place where delivery people, designers, and engineers genuinely connect, and where everyone has a voice, space to grow, and a little fun along the way.

As a Senior iOS Engineer at Bilue, you’ll be part of a cross-functional team that brings bold ideas to life. Your craft will shape apps that are not just fast and reliable, but a joy for people to use every day.

Working side by side with our clients, you’ll turn their vision into elegant, scalable solutions. By leaning into the latest iOS frameworks and agile ways of working, you’ll help us deliver software that feels effortless on the surface and powerful underneath, the kind of work that makes a lasting mark.
