At Centrapay, we’re revolutionising how you spend money both in-store and online. We allow businesses to create digital assets and loyalty programmes so that you can spend and be rewarded anywhere. Some of our partners include Coca-Cola, BNZ, and Farmlands, and we process payments in New Zealand and Australia.

Our payments platform is the heartbeat of what we do. On top of this, we're building our hero app, Payap, that brings all of our best capabilities to life.

We're looking for a mobile engineer who will be the driving force behind Payap's Flutter development, loves building great consumer-facing products, enjoys supporting their teammates, and who is resilient in the face of ambiguous problems. You'll be our go-to person for mobile architecture decisions and will shape how we deliver mobile experiences to our users. In return, we'll provide you with a supportive environment to grow and teach you how we use our tools to build amazing payment experiences.

💅 Your day-to-day

• We prioritise automation, test-driven development, and continuous deployment. You’ll be deploying code to production almost every day, including your very first day!
• Be the primary contributor to Payap's codebase, driving feature development and architectural decisions that will shape our mobile platform
• Streamline Payap's performance and implement robust observability solutions to ensure our mobile app delivers exceptional user experiences
• Own and improve our mobile continuous delivery pipeline, making it faster and more reliable for the entire team
• Integrate Payap with backend services via RESTful APIs and other communication protocols
• Lead design sessions with your team, design and product stakeholders to collaborate on upcoming mobile requirements and solution design
• Support your teammates through code reviews, pair programming and thoughtful guidance that helps them develop their skills and confidence
• Benefit from dedicated support, including a manager focused on accelerating your growth and a comprehensive 2-month onboarding program to get you up to speed.
• Dedicate 10% of your time to self-directed learning, empowering you to explore new ideas and develop your expertise

Requirements

👀 Who we're looking for

• Strong Flutter experience is essential - you've shipped consumer-facing Flutter apps to production, understand the ecosystem deeply, and can architect scalable mobile solutions
• A builder. Your happy place is crafting intuitive mobile experiences that users love, with code that is both performant and maintainable
• A writer. You can communicate ideas effectively through writing to fit in with our bias for async-first working and public-first transparency
• A designer. You think through mobile UX solutions before building, have a customer-first mindset, and design with future mobile needs in mind
• A leader. You've got experience promoting mobile engineering best practices within your team, championing testable mobile code, and driving mobile DevOps improvements including CI/CD pipelines
• An owner. If you build it, you care deeply about how it performs for users on their devices, and you implement monitoring and observability to prove it
• A mentor. You've got experience supporting more junior mobile developers in ways that encourage learning and independent problem-solving
• A proactive mentality where you can steer yourself through an ambiguous mobile problem, grab help when you need it, and come up with something great
