Senior Mobile Software Engineer (React Native)

Who We Are:

Amused Group is a fast-growing online wagering and technology company operating across Australia and international markets. We build and scale high-performance platforms across sports and racing, backed by a culture of accountability, speed, and continuous improvement.

We operate as a global, remote-first team and are focused on delivering outcomes, not just activity.

Who You Are:

• You are an exceptional mobile software engineer with extensive experience designing, building, and evolving large-scale, production-grade mobile applications using React Native.
• You are the technical authority for mobile engineering, capable of making sound architectural decisions, solving the most challenging technical problems, and defining engineering standards that enable the entire team to build high-quality mobile applications.
• You understand that building world-class React Native applications extends beyond JavaScript.
• You are comfortable working within the native Android and iOS projects to troubleshoot platform-specific issues, integrate native SDKs, implement native functionality, and optimise application behaviour when React Native abstractions are insufficient.
• You have a deep understanding of mobile application architecture, performance, security, reliability, and user experience, and you instinctively design solutions that are scalable, maintainable, and resilient.
• You provide technical leadership through architecture, engineering standards, design reviews, and mentorship.
• You enjoy evaluating emerging technologies and frameworks, balancing innovation with pragmatism to make sound long-term technical decisions.
• You understand technology at a fundamental level, enabling you to troubleshoot problems across the JavaScript runtime, native mobile platforms, networking, backend integrations, and cloud infrastructure.
• You have experience with modern software development methodologies such as spec-driven development and AI-assisted development, and are adept at using tools such as Cursor, Kiro, Claude Code and similar technologies to improve engineering productivity and software quality.
• You continuously seek opportunities to improve engineering practices, developer experience, automation, and product quality.

What You Will Do:

• Own the technical direction of the company's mobile platform and establish architectural standards for all mobile applications.
• Design and evolve scalable, maintainable, secure, and high-performance mobile application architectures using React Native.
• Make technology and design decisions that balance long-term maintainability, performance, developer productivity, and business outcomes.
• Lead technical investigations and solve the most challenging mobile engineering problems.
• Review architecture, technical designs, and code to ensure consistency, maintainability, quality, and adherence to engineering standards.
• Work directly within native Android using Kotlin/Java and iOS using Swift/Objective-C projects to resolve platform-specific issues, implement native functionality, develop native modules, and integrate third-party SDKs.

• Define engineering standards, reusable frameworks, shared components, and best practices that improve consistency across all mobile applications.
• Drive improvements in application startup time, rendering performance, memory usage, battery consumption, networking efficiency, and overall user experience.
• Own the technical aspects of the mobile release lifecycle, including build automation, CI/CD, code signing, TestFlight, App Store Connect, Google Play Console, release management, and production deployments.
• Evaluate new technologies, frameworks, libraries, and tooling, making recommendations based on technical and business trade-offs.
• Partner closely with backend, frontend, DevOps, QA, and product teams to design robust end-to-end solutions.
• Champion engineering excellence through automated testing, observability, documentation, code reviews, and continuous improvement initiatives.
• Mentor engineers through technical guidance, design discussions, and architectural reviews, fostering engineering excellence across the team.
