We're building the OS for Hospitality. Want to shape the mobile experience?

At
Oolio
, we're creating the foundational platform that powers hospitality businesses across Australia and beyond. From in-venue ordering and payments to delivery, loyalty, and staff tooling—our mobile interfaces are often the
first and most critical touchpoint
for merchants and customers alike.

As we embed
AI across our product suite
—from smart chatbots to partner MCPs—we're looking for a
Senior Mobile Engineer
who can craft reliable, performant, and resilient apps that work in the real-world constraints of the venues we serve.

What you'll do at Oolio

  • Lead development of
    cross-platform and native mobile applications
    , especially in
    Kotlin
    (Android) or
    React Native/Flutter
  • Build and ship mobile-first experiences that are
    mission-critical
    ,
    offline-capable
    , and optimized for
    low memory and CPU devices
    .
  • Leverage
    AI tools
    to accelerate development, improve test coverage, and ship with confidence.
  • Collaborate closely with design, product, and backend teams to deliver intuitive and responsive user experiences.
  • Architect solutions with
    offline-first patterns
    , background sync, and local persistence.
  • Drive reliability, performance, and resilience across POS and SoftPOS integrations.

Who you are

  • 7+ years of strong product development experience
  • 5+ years
    working with building and shipping
    Kotlin-based Android apps
    and understand Android internals and constraints well.
  • You have good working experience with
    Flutter or React Native
    , and can navigate trade-offs across platforms.
  • You've worked on
    mission-critical systems
    — where reliability, speed, and fault tolerance matter.
  • You've built apps for
    low-spec hardware
    or environments with
    limited connectivity
    , using
    offline-first design patterns
    .
  • You care deeply about
    performance, user experience, and code quality
    .
  • You actively use
    AI tools
    like Copilot, Claude, or Coderabbit in your development workflow.
  • Experience working with
    POS or payment terminals
    is a strong plus.

What it's like to work at Oolio

  • We value
    impact over ceremony
    and
    real-world outcomes over theoretical perfection
    .
  • We embed
    AI into our workflows
    , enabling faster builds, better ideas, and smarter code.
  • We work
    hybrid
    , with a collaborative and high-trust engineering culture.
  • Our apps power thousands of venues across Australia—you'll see the impact of your work immediately.

Why now?

  • Help define the
    mobile layer of the OS for hospitality
    .
  • Work on real-time, offline-capable systems used in production daily.
  • Join a fast-moving team committed to
    craft, autonomy, and AI-first development
    .
  • Build products used at the heart of cafes, restaurants, and venues across the country.

Let's build the future of mobile hospitality software—together.
