Job description

Salary: Up to $160,000 per annum + potential equity/package (depending on experience)

About the Opportunity

We're supporting an innovative technology company building AI-native products designed to transform how people manage communication, organization, workflows, and daily tasks.

The team is developing intelligent assistant technology focused on real-world task completion, long-running workflows, persistent context, and highly reliable AI experiences. Their vision is to create products that help users accomplish more with significantly less effort, making AI genuinely useful in everyday life.

This is an opportunity to join a small, high-performing team where engineering excellence, product quality, and rapid execution are highly valued.

The Role

As an iOS Mobile Engineer, you will own and shape the mobile experience of a sophisticated AI-powered application.

This is not a traditional mobile development position focused solely on building interfaces. You will play a key role in defining how AI interactions feel on mobile, ensuring experiences are intuitive, performant, reliable, and trustworthy.

Working closely with backend and machine learning engineers, you will contribute to the development of production-grade AI features that users rely on every day.

Key Responsibilities

• Build and maintain high-quality iOS applications using Swift and SwiftUI
• Integrate AI-powered capabilities through backend APIs and platform services
• Design seamless AI interaction patterns, including:
• Streaming responses
• Loading states
• Retry mechanisms
• User-friendly fallback experiences
• Optimize application performance, memory consumption, responsiveness, and battery efficiency
• Implement analytics and feedback mechanisms to support AI evaluation and product improvements
• Collaborate closely with backend, platform, and machine learning teams on API design and product behavior
• Maintain high standards of application quality, stability, testing, and production readiness
• Contribute to architectural and technical decisions that support future growth and scalability

Required Experience

• 7+ years of professional iOS development experience
• Strong proficiency in Swift and SwiftUI
• Experience building, shipping, and maintaining production iOS applications
• Hands-on experience integrating AI-powered or intelligent product features into mobile applications
• Strong understanding of:
• Swift Concurrency
• Background processing
• API integration
• Proven experience optimizing mobile performance and memory usage
• Experience designing solutions that account for latency, partial failures, and unpredictable system behaviour
• Strong problem-solving capabilities and attention to detail

Preferred Experience

• Exposure to CoreML or on-device machine learning technologies
• Experience with TensorFlow Lite or similar mobile inference frameworks
• Familiarity with feature flagging and remote configuration systems
• Understanding of AI product design principles and user trust considerations
• Experience working within startup, scale-up, or high-growth environments

Success in This Role

You will be successful if you help deliver:

• Stable, reliable, and high-performing iOS applications
• Fast and responsive user experiences with efficient memory and CPU usage
• AI-powered features that users trust and engage with regularly
• Effective monitoring and rapid resolution of production issues
• Continuous improvements to product quality, reliability, and user satisfaction
• Swift
• SwiftUI
• SQL / NoSQL Databases
• TensorFlow Lite (On-Device Inference)

Working Style

The company believes exceptional products are built by small, talented teams with high ownership and strong technical standards.

You will work in an environment that values:

• Independent thinking
• Continuous learning
• Delivering high-quality outcomes

This role offers significant autonomy and the opportunity to influence both product direction and technical strategy.

Interview Process

The interview process has been designed to be transparent and efficient, consisting of up to four stages, including technical assessments and discussions with key team members.

Applications are reviewed directly by experienced engineers and hiring stakeholders, with a focus on technical capability, problem-solving ability, and alignment with a high-performance culture.

If you're excited about building AI-native mobile products and want to help shape the future of intelligent software, we'd love to hear from you.
